"I'm so sad": Woman declined entry into music venue because of her baby

<p>A mother has shared her frustration after she was denied entry into a live music venue due to the fact that she had her baby with her. </p> <p>Jasmine and her partner were excited to see one of their favourite artists, Angie McMahon, at Melbourne's iconic concert venue The Forum, and made the decision to bring their five-month-old baby with them. </p> <p>The baby was strapped to the mum's chest in a carrier and was wearing headphones, but jasmine was soon confronted by venue staff that she was not allowed entry into the venue, and instead offered to return without their child for another night.</p> <p>The singer herself later called in to the <em>3AW</em> radio show, where Jasmine had recalled the incident, to say that she would not have minded having a baby in the audience.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C7lk_LGPqta/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C7lk_LGPqta/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by 3AW Melbourne (@3aw693)</a></p> </div> </blockquote> <p>“I’m so sad.

Are young people smarter than older adults? My research shows cognitive differences between generations are diminishing

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/stephen-badham-1531316">Stephen Badham</a>, <a href="https://theconversation.com/institutions/nottingham-trent-university-1338">Nottingham Trent University</a></em></p> <p>We often assume young people are smarter, or at least quicker, than older people. For example, we’ve all heard that scientists, and even more so mathematicians, <a href="https://www.forbes.com/sites/nextavenue/2014/08/07/who-says-scientists-peak-by-age-50/">carry out their most important work</a> when they’re comparatively young.</p> <p>But my new research, <a href="https://www.sciencedirect.com/science/article/pii/S027322972400008X#:%7E:text=Highlights&amp;text=Three%20review%20studies%20measure%20secular,%2C%20education%2C%20and%20overall%20health.">published in Developmental Review</a>, suggests that cognitive differences between the old and young are tapering off over time. This is hugely important as stereotypes about the intelligence of people in their sixties or older may be holding them back – in the workplace and beyond.</p> <p>Cognitive ageing is often measured by comparing young adults, aged 18-30, to older adults, aged 65 and over. There are a variety of tasks that older adults do not perform well on compared to young adults, such as memory, spatial ability and speed of processing, which often form the basis of <a href="https://theconversation.com/the-iq-test-wars-why-screening-for-intelligence-is-still-so-controversial-81428">IQ tests</a>. That said, there are a few tasks that older people do better at than younger people, such as reading comprehension and vocabulary.</p> <p>Declines in cognition are driven by a process called <a href="https://www.nature.com/collections/cbjacdabdf">cognitive ageing</a>, which happens to everyone. Surprisingly, age-related cognitive deficits start very early in adulthood, and declines in cognition have been measured as dropping in adults as young as just 25.</p> <p>Often, it is only when people reach older age that these effects add up to a noticeable amount. Common complaints consist of walking into a room and forgetting why you entered, as well as difficulty remembering names and struggling to drive in the dark.</p> <h2>The trouble with comparison</h2> <p>Sometimes, comparing young adults to older adults can be misleading though. The two generations were brought up in different times, with different levels of education, healthcare and nutrition. They also lead different daily lives, with some older people having lived though a world war while the youngest generation is growing up with the internet.</p> <p>Most of these factors favour the younger generation, and this can explain a proportion of their advantage in cognitive tasks.</p> <p>Indeed, much existing research shows that <a href="https://theconversation.com/iq-tests-are-humans-getting-smarter-158837">IQ has been improving</a> globally throughout the 20th century. This means that later-born generations are more cognitively able than those born earlier. This is even found when both generations are tested in the same way at the same age.</p> <p>Currently, there is growing evidence that <a href="https://www.pnas.org/doi/10.1073/pnas.1718793115">increases in IQ are levelling off,</a> such that, in the most recent couple of decades, young adults are no more cognitively able than young adults born shortly beforehand.</p> <p>Together, these factors may underlie the current result, namely that cognitive differences between young and older adults are diminishing over time.</p> <h2>New results</h2> <p>My research began when my team started getting strange results in our lab. We found that often the age differences we were getting between young and older adults was smaller or absent, compared to prior research from early 2000s.</p> <p>This prompted me to start looking at trends in age differences across the psychological literature in this area. I uncovered a variety of data that compared young and older adults from the 1960s up to the current day. I plotted this data against year of publication, and found that age deficits have been getting smaller over the last six decades.</p> <p>Next, I assessed if the average increases in cognitive ability over time seen across all individuals was a result that also applied to older adults specifically. Many large databases exist where groups of individuals are recruited every few years to take part in the same tests. I analysed studies using these data sets to look at older adults.</p> <p>I found that, just like younger people, older adults were indeed becoming more cognitively able with each cohort. But if differences are disappearing, does that mean younger people’s improvements in cognitive ability have slowed down or that older people’s have increased?</p> <p>I analysed data from my own laboratory that I had gathered over a seven-year period to find out. Here, I was able to dissociate the performance of the young from the performance of the older. I found that each cohort of young adults was performing to a similar extent across this seven-year period, but that older adults were showing improvements in both processing speed and vocabulary scores.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=333&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=333&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=333&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=418&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=418&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/591482/original/file-20240501-24-esxcic.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=418&amp;fit=crop&amp;dpr=3 2262w" alt="The figure shows data for a speed-based task where higher scores represent better performance." /><figcaption><span class="caption">The figure shows data for a speed-based task where higher scores represent better performance.</span> <span class="attribution"><a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <p>I believe the older adults of today are benefiting from many of the factors previously most applicable to young adults. For example, the number of children who went to school <a href="https://education-uk.org/history/chapter12.html">increased significantly</a> in the 1960s – with the system being more similar to what it is today than what it was at the start of the 20th century.</p> <p>This is being reflected in that cohort’s increased scores today, now they are older adults. At the same time, young adults have hit a ceiling and are no longer improving as much with each cohort.</p> <p>It is not entirely clear why the young generations have stopped improving so much. Some research has <a href="https://doi.org/10.1016/j.intell.2016.10.002">explored maternal age, mental health and even evolutionary trends</a>. I favour the opinion that there is just a natural ceiling – a limit to how much factors such as education, nutrition and health can improve cognitive performance.</p> <p>These data have important implications for research into dementia. For example, it is possible that a modern older adult in the early stages of dementia might pass a dementia test that was designed 20 or 30 years ago for the general population at that time.</p> <p>Therefore, as older adults are performing better in general than previous generations, it may be necessary to revise definitions of dementia that depend on an individuals’ expected level of ability.</p> <p>Ultimately, we need to rethink what it means to become older. And there’s finally some good news. Ultimately, we can expect to be more cognitively able than our grandparents were when we reach their age.<!-- Below is The Conversation's page counter tag.

New studies suggest millions with mild cognitive impairment go undiagnosed, often until it’s too late

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/soeren-mattke-1484707">Soeren Mattke</a>, <a href="https://theconversation.com/institutions/university-of-southern-california-1265">University of Southern California</a> and <a href="https://theconversation.com/profiles/ying-liu-1221170">Ying Liu</a>, <a href="https://theconversation.com/institutions/usc-dornsife-college-of-letters-arts-and-sciences-2669">USC Dornsife College of Letters, Arts and Sciences</a></em></p> <p>Mild cognitive impairment – an early stage of dementia – is widely underdiagnosed in people 65 and older. That is the key takeaway of two recent studies from our team.</p> <p>In the first study, we used Medicare data for about 40 million beneficiaries age 65 and older from 2015 to 2019 to estimate the prevalence of mild cognitive impairment in that population and to identify what proportion of them had actually been diagnosed.</p> <p>Our <a href="https://doi.org/10.1186/s13195-023-01272-z">finding was sobering</a>: A mere 8% of the number of cases with mild cognitive impairment that we expected based on a statistical model had actually been diagnosed. Scaled up to the general population 65 and older, this means that approximately 7.4 million cases across the country remain undiagnosed.</p> <p>In the second study, we analyzed data for 226,756 primary care clinicians and found that <a href="https://doi.org/10.14283/jpad.2023.131">over 99% of them underdiagnosed mild cognitive impairment</a> in this population.</p> <h2>Why it matters</h2> <p>Mild cognitive impairment is an early symptom of Alzheimer’s disease in <a href="https://doi.org/10.1001/jama.2019.2000">about half of cases</a> and progresses to dementia <a href="https://www.alz.org/alzheimers-dementia/what-is-dementia/related_conditions/mild-cognitive-impairment">at a rate of 10% to 15% per year</a>. It includes symptoms such as losing the ability to remember recent events and appointments, make sound decisions and master complex tasks. Failure to detect it might deprive patients of an opportunity to get treated and to slow down disease progression.</p> <p>Mild cognitive impairment can sometimes be caused by easily addressable factors, such as medication side effects, thyroid dysfunction or <a href="https://theconversation.com/vitamin-b12-deficiency-is-a-common-health-problem-that-can-have-serious-consequences-but-doctors-often-overlook-it-192714">vitamin B12 deficiency</a>. Since mild cognitive impairment has <a href="https://doi.org/10.1016/j.amjopharm.2008.06.004">the same risk factors as cardiovascular disease</a>, such as high blood pressure and cholesterol, medication management of these risks combined with diet and exercise <a href="https://doi.org/10.1016/S0140-6736(15)60461-5">can reduce the risk of progression</a>.</p> <p>In 2023, the Food and Drug Administration <a href="https://www.fda.gov/news-events/press-announcements/fda-converts-novel-alzheimers-disease-treatment-traditional-approval">approved the drug lecanemab</a> as the <a href="https://theconversation.com/what-the-fdas-accelerated-approval-of-a-new-alzheimers-drug-could-mean-for-those-with-the-disease-5-questions-answered-about-lecanemab-197460">first disease-modifying treatment</a> <a href="https://www.nia.nih.gov/health/alzheimers-causes-and-risk-factors/what-happens-brain-alzheimers-disease">for Alzheimer’s disease</a>, the most common cause of mild cognitive impairment. In contrast to previous drugs, which can temporarily improve symptoms of the disease, such as memory loss and agitation, this new treatment addresses the underlying cause of the disease.</p> <p>Lecanemab, a monoclonal antibody, <a href="https://www.news-medical.net/health/What-are-Amyloid-Plaques.aspx">reduces amyloid plaques</a> in the brain, which are toxic protein clumps that are believed to contribute to the progression of the disease. In a large clinical trial, lecanemab was able to <a href="https://doi.org/10.1056/NEJMoa2212948">reduce the progression</a> of early-stage Alzheimer’s disease. A similar drug, donanemab, also <a href="https://doi.org/10.1001/jama.2023.13239">succeeded in a clinical trial</a> and is expected to be <a href="https://www.medicalnewstoday.com/articles/fda-delays-approval-of-alzheimers-drug-donanemab-what-experts-think">approved sometime in 2024</a>.</p> <p>However, these drugs must be used in the early stages of Alzheimer’s disease, ideally when a patient has only mild cognitive impairment, as there is <a href="https://www.alz.org/alzheimers-dementia/treatments/lecanemab-leqembi">no evidence that they are effective in advanced stages</a>.</p> <figure><iframe src="https://www.youtube.com/embed/w3IbAscNjsQ?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">An earlier diagnosis leads to early treatment and better outcomes.</span></figcaption></figure> <h2>What still isn’t known</h2> <p>Many factors contribute to the <a href="https://doi.org/10.1002/alz.13051">lack of timely detection</a>. But researchers don’t have a good understanding of the relative importance of those individual factors or how to reduce the high rate of underdiagnosis.</p> <p>While distinct, symptoms are subtle and their slow progression means that they can be overlooked or misinterpreted as normal aging. A neurologist in China told our research team that diagnosis rates spike in China after the New Year’s holiday, when children who haven’t seen their parents for a year notice changes that are harder to pick up when interacting with someone daily.</p> <p>Doctors also commonly discount memory concerns as normal aging and doubt that much can be done about it. While cognitive tests to distinguish mild cognitive impairment from pathologic decline do exist, they take about 15 minutes, which can be hard to come by during the limited time of a doctor’s visit and may require a follow-up appointment.</p> <h2>What’s next</h2> <p>People, particularly those in their 60s and beyond, as well as their families and friends need to be vigilant about cognitive decline, bring it up during doctor’s appointments and insist on a formal assessment.</p> <p>The <a href="https://www.medicare.gov/coverage/yearly-wellness-visits">Medicare yearly “wellness” visit</a> is an opportunity to explore such concerns, but only about half of beneficiaries <a href="https://doi.org/10.1377/hlthaff.2019.01795">take advantage of it</a>.</p> <p>Just as physicians ask patients about unexplained weight loss and take those concerns seriously, we believe questions that explore a patient’s cognitive state need to become the norm.</p> <p><em>The <a href="https://theconversation.com/us/topics/research-brief-83231">Research Brief</a> is a short take on interesting academic work.</em><!-- Below is The Conversation's page counter tag.

Steep physical decline with age is not inevitable – here’s how strength training can change the trajectory

<p><em><a href="https://theconversation.com/profiles/zachary-gillen-1251178">Zachary Gillen</a>, <a href="https://theconversation.com/institutions/mississippi-state-university-1970">Mississippi State University</a></em></p> <p>Raise your hand if you regularly find yourself walking up a flight of stairs. What about carrying heavy bags of groceries? How about picking up your child or grandchild? Most of us would raise our hands to doing at least one of those weekly, or even daily.</p> <p>As people age, it can become more and more difficult to perform some physical tasks, even those that are normal activities of daily living. However, prioritizing physical fitness and health as you get older can help you go through your normal day-to-day routine without feeling physically exhausted at the end of the day.</p> <p>It can also help you continue to have special memories with your family and loved ones that you might not have been able to have if you weren’t physically active. For example, I ran two half-marathons with my dad when he was in his 60s!</p> <p>I am an exercise physiologist who studies how people can <a href="https://scholar.google.com/citations?user=gn8ZiLMAAAAJ&amp;hl=en">use resistance training to improve human performance</a>, whether it be in sports and other recreational settings, in everyday life, or both. I am also a certified strength and conditioning specialist. My career has given me the opportunity to design exercise programs for kids, college athletes and elderly adults.</p> <p>Staying physically active as you get older doesn’t need to include running a half-marathon or trying to be a bodybuilder; it could be as simple as trying to get through the day without feeling winded after you go up a flight of stairs. Although our muscles naturally get weaker as we age, there are ways we can combat that to help improve quality of life as we get older.</p> <h2>Muscle loss and chronic disease</h2> <p>One of the most important parts of exercise programming, no matter who I am working with, is proper resistance training to build muscle strength. Some amount of age-related loss of muscle function is normal and inevitable. But by incorporating resistance training that is appropriate and safe at any ability level, you can slow down the rate of decline and even prevent some loss of muscle function.</p> <p>The medical term for a condition that involves <a href="https://doi.org/10.1093/ageing/afy169">age-related loss of muscle function and mass is sarcopenia</a>. Sarcopenia can begin as early as age 40, but it tends to be <a href="https://doi.org/10.1097/01.mco.0000134362.76653.b2">more common in adults age 60 and older</a>. Sarcopenia is associated with a number of health issues such as <a href="https://doi.org/10.1093/gerona/glx245">increased risk of falling</a>, <a href="https://doi.org/10.1161/CIRCULATIONAHA.123.064071">cardiovascular disease</a> and <a href="https://doi.org/10.3390/nu13103519">metabolic disease</a>, among others.</p> <p>In one of our team’s previous studies, we saw that otherwise healthy individuals with sarcopenia had issues <a href="https://doi.org/10.1002/jcsm.12932">delivering vital nutrients to muscle</a>. This could lead to greater likelihood of various diseases, such as Type 2 diabetes, and slow down recovery from exercise.</p> <p>Recent estimates suggest that sarcopenia affects <a href="https://doi.org/10.1016/j.metabol.2023.155533">10% to 16% of the elderly population worldwide</a>. But even if a person doesn’t have clinically diagnosed sarcopenia, they may still have some of the underlying symptoms that, if not dealt with, could lead to sarcopenia.</p> <h2>Strength training is key</h2> <p>So the question is, what can be done to reverse this decline?</p> <p>Recent evidence suggests that one of the key factors leading to sarcopenia is <a href="https://doi.org/10.1093/gerona/glx245">low muscle strength</a>. In other words, combating or reversing sarcopenia, or both, may be best done with a proper resistance-training program that <a href="https://doi.org/10.1186/s12877-021-02642-8">prioritizes improving strength</a>. In fact, the decline in muscle strength seems to <a href="https://doi.org/10.3945/ajcn.2009.28047">occur at a much faster rate</a> than the decline in muscle size, underscoring the importance of proper strength training as people age.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=638&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=638&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=638&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=802&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=802&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=802&amp;fit=crop&amp;dpr=3 2262w" alt="Chart showing the general pattern for changes in muscle strength and size across stage of life." /></a><figcaption><span class="caption">Typical age-related changes in muscle strength and size with and without strength training.</span> <span class="attribution"><span class="source">Zachary Gillen</span></span></figcaption></figure> <p>Continuing to regularly strength train with moderate to heavy weights has been shown to be not only effective at combating the symptoms of sarcopenia but also <a href="https://doi.org/10.1016/j.jamda.2018.09.011">very safe when done properly</a>. The best way to make sure you are strength training properly is to seek out guidance from a qualified individual such as a personal trainer or strength and conditioning specialist.</p> <p>Despite the clear benefits of strength training, it’s been shown that only about 13% of Americans age 50 and older do some form of <a href="https://pubmed.ncbi.nlm.nih.gov/17572957/">strength training at least twice a week</a>.</p> <h2>Finding what works for you</h2> <p>So how does a person properly strength train as they age?</p> <p>The National Strength and Conditioning Association, a leading organization in advancing strength and conditioning around the world, states that for older adults, <a href="https://doi.org/10.1519/JSC.0000000000003230">two to three days per week of strength training</a> can be incredibly helpful for maintaining healthy muscle and bone and combating a number of chronic conditions.</p> <p>The organization recommends that these workouts involve one to two exercises involving multiple joints per major muscle group, with six to 12 repetitions per set. These are done at an intensity of 50% to 85% of what’s known as one-repetition maximum – the most weight you could handle for a single repetition – with the exception of body weight exercises that use one’s own body weight as the resistance, such as pushups.</p> <p>I would also recommend resting for about two to three minutes between sets, or even up to five minutes if the set was challenging. For older adults, particularly those age 60 and older, the National Strength and Conditioning Association guidelines suggest that a program like this be performed two to three days per week, with 24 to 48 hours between sessions.</p> <p><iframe id="sGvo5" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/sGvo5/3/" width="100%" height="400px" frameborder="0"></iframe></p> <h2>Making life’s tasks lighter</h2> <p>The guidelines above are only one example out of many options, but they provide a framework that you can use to build your own program. However, I would highly recommend seeking out a professional in the field to give specific exercise programming advice that can be tailored to your own needs and goals as you age.</p> <p>Following such a program would give your muscles an excellent stimulus to enhance strength, while also allowing enough recovery, a very important consideration as people age. You might think it looks like a huge time commitment, but an exercise routine like this can be done in less than an hour. This means that in less than three hours of strength training per week you can help improve your muscle health and reduce the risk of getting sarcopenia and associated health issues.</p> <p>It’s also important to note that there is no one right way to do resistance training, and it needn’t involve traditional weight equipment. Group classes like Pilates and yoga or those that involve circuit training and work with resistance bands can all produce similar results. The key is to get out and exercise regularly, whatever that entails.<!-- Below is The Conversation's page counter tag.

Can a daily multivitamin improve your memory?

<p><a href="https://theconversation.com/profiles/jacques-raubenheimer-1144463">Jacques Raubenheimer</a>, <em><a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em><a href="https://theconversation.com/au/topics/research-check-25155">Research Checks</a> interrogate newly published studies and how they’re reported in the media. The analysis is undertaken by one or more academics not involved with the study, and reviewed by another, to make sure it’s accurate.</em></p> <hr /> <p>Don’t we all want to do what we can to reduce the impact of age-related decline on our memory?</p> <p>A new study suggests a daily multivitamin and mineral supplement is a simple and inexpensive way to help older adults slow the decline in some aspects of memory function.</p> <p>The <a href="https://ajcn.nutrition.org/article/S0002-9165(23)48904-6/fulltext">new study</a>, which comes from a <a href="https://www.clinicaltrials.gov/ct2/show/NCT02422745?term=NCT02422745&amp;draw=2&amp;rank=1">long-running clinical trial</a>, shows there may be a small benefit of taking a daily multivitamin and mineral supplement for one type of cognitive task (immediate word recall) among well-functioning elderly white people. At least in the short term.</p> <p>But that doesn’t mean we should all rush out and buy multivitamins. The results of the study don’t apply to the whole population, or to all types of memory function. Nor does the study show long-term benefits.</p> <h2>How was the study conducted?</h2> <p>The overarching COSMOS study is a well-designed double-blind randomised control trial. This means participants were randomly allocated to receive the intervention (a daily multivitamin and mineral supplement) or a placebo (dummy tablet), but neither the participants nor the researchers knew which one they were taking.</p> <p>This type of study is considered the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5654877/">gold standard</a> and allows researchers to compare various outcomes.</p> <p>Participants (3,562) were older than 64 for women, and 59 for men, with no history of heart attack, invasive cancer, stroke or serious illness. They couldn’t use multivitamins or minerals (or <a href="https://www.pnas.org/doi/10.1073/pnas.2216932120">cocoa extract</a> which they also tested) during the trial.</p> <p>Participants completed a <a href="https://www.clinicaltrials.gov/ct2/show/NCT04582617?term=NCT04582617&amp;draw=2&amp;rank=1">battery of online cognitive tests</a> at the start of the study (known as baseline), then yearly for three years, of which only three were reported in this paper:</p> <ul> <li> <p>ModRey, measuring immediate recall. Participants were shown “a list of 20 words, one at a time, for three seconds each,” and then had to type the list from memory</p> </li> <li> <p>ModBent, measuring object recognition. Participants were given 20 prompts with a shape and then had to select the correct match from a pair of similar prompts. After this, they were prompted with 40 shapes in turn, and had to indicate whether each was included in the original 20 or not</p> </li> <li> <p>Flanker, measuring “executive control”. Participants had to select a coloured block that corresponded to an arrow in a matrix of arrows, which could have the same (or different) colour to the surrounding arrows, and the same (or different) direction as the prompt block.</p> </li> </ul> <h2>What did the researchers find?</h2> <p>Of all the tests the researchers performed, only immediate recall (ModRey) at one year showed a significant effect, meaning the result is unlikely to just be a result of chance.</p> <p>At two and three years, the effect was no longer significant (meaning it could be down to chance).</p> <p>However they added an “overall estimate” by averaging the results from all three years to arrive at another significant effect.</p> <p>All the effect sizes reported are very small. The largest effect is for the participants’ immediate recall at one year, which was 0.07 – a value that is <a href="https://academic.oup.com/jpepsy/article/34/9/917/939415">generally considered very small without justification</a>.</p> <p>Also of note is that both the multivitamin and placebo groups had higher immediate word recall scores at one year (compared to baseline), although the multivitamin group’s increase was significantly larger.</p> <p><a href="https://www.pnas.org/doi/epdf/10.1073/pnas.2216932120">In the researchers’ prior study</a>, the increase in word recall scores was described as a “typical learning (practice) effect”. This means they attributed the higher scores at one year to familiarisation with the test.</p> <p>For some reason, this “learning effect” was not discussed in the current paper, where the treatment group showed a significantly larger increase compared to those who were given the placebo.</p> <h2>What are the limitations of the study?</h2> <p>The team used a suitable statistical analysis. However, it did not adjust for demographic characteristics such as age, gender, race, and level of education.</p> <p>The authors detail their study’s major limitation well: it is not very generalisable, as it used “mostly white participants” who had to be very computer literate, and, one could argue, would be quite well-functioning cognitively.</p> <figure class="align-center "><figcaption></figcaption>Another unmentioned limitation is the advanced age of their sample, meaning long-term results for younger people can’t be assessed.</figure> <p>Additionally, the baseline diet score for their sample was abysmal. The researchers say participants’ diet scores “were consistent with <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/1899558">averages from the US population</a>” but the cited study noted “the overall dietary quality… [was] poor.”</p> <p>And they didn’t measure changes in diet over the three years, which could impact the results.</p> <h2>How should we interpret the results?</h2> <p>The poor dietary quality of the sample raises the question: can a better diet be the simple fix, rather than multivitamin and mineral supplements?</p> <p>Even for the effect they observed, which micronutrient from the supplement was the contributing factor?</p> <p>The researchers speculate about vitamins B12 and D. But you can find research on cognitive function for any arbitrarily chosen <a href="https://www.centrum.com/content/dam/cf-consumer-healthcare/bp-wellness-centrum/en_US/pdf/lbl-00000775-web-ready-centrum-silver-adults-tablets-(versio.pdf">ingredient</a>, including <a href="https://scholar.google.com/scholar?hl=en&amp;as_sdt=0%2C5&amp;q=selenium+cognitive+function">selenium</a>, which can be <a href="https://www.sciencedirect.com/science/article/pii/S0048969720378608">toxic at high levels</a>.</p> <h2>So should I take a multivitamin?</h2> <p><a href="https://newsinhealth.nih.gov/2013/08/should-you-take-dietary-supplements">Health authorities advise</a> daily multivitamin use isn’t necessary, as you can get all the nutrients you need by eating a wide variety of healthy foods. However, supplementation may be appropriate to meet any specific nutrient gaps an individual has.</p> <p>Using a good quality multivitamin at the recommended dose shouldn’t do any harm, but at best, this study shows well-functioning elderly white people might show some additional benefit in one type of cognitive task from using a multivitamin supplement.</p> <p>The case for most of the rest of the population, and the long-term benefit for younger people, can’t be made.</p> <hr /> <h2>Blind peer review</h2> <p><strong>Clare Collins writes:</strong></p> <p>I agree with the reviewer’s assessment, which is a comprehensive critique of the study. The key result was a small effect size from taking a daily multivitamin and mineral (or “multinutrient”) supplement on memory recall at one year (but not later time points) and is equivalent to a training effect where you get better at taking a test the more times you do it.</p> <p>It’s also worth noting the study authors received support and funding from commercial companies to undertake the study.</p> <p>While the study authors state they don’t believe background diet quality impacted the results, they didn’t comprehensively assess this. They used a brief <a href="https://pubmed.ncbi.nlm.nih.gov/22513989/">diet quality assessment score</a> only at baseline. Participants may have changed their eating habits during the study, which could then impact the results.</p> <p>Given all participants reported low diet quality scores, an important question is whether giving participants the knowledge, skills and resources to eat more healthily would have a bigger impact on cognition than taking supplements. <!-- Below is The Conversation's page counter tag.

What is cognitive functional therapy? How can it reduce low back pain and get you moving?

<p><em><a href="https://theconversation.com/profiles/peter-osullivan-48973">Peter O'Sullivan</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/jp-caneiro-1463060">JP Caneiro</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/peter-kent-1433302">Peter Kent</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p>If you haven’t had lower back pain, it’s likely you know someone who has. It affects <a href="https://pubmed.ncbi.nlm.nih.gov/22231424/">around 40% of adults</a> in any year, ranging from adolescents to those in later life. While most people recover, <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">around 20%</a> go on to develop chronic low back pain (lasting more than three months).</p> <p>There is a <a href="https://bjsm.bmj.com/content/54/12/698">common view</a> that chronic low back pain is caused by permanent tissue damage including “wear and tear”, disc degeneration, disc bulges and arthritis of the spine. This “damage” is often described as resulting from injury and loading of the spine (such as bending and lifting), ageing, poor posture and weak “core” muscles.</p> <p>We’re often told to “protect” our back by sitting tall, bracing the core, keeping a straight back when bending and lifting, and avoiding movement and activities that are painful. Health practitioners often <a href="https://theconversation.com/having-good-posture-doesnt-prevent-back-pain-and-bad-posture-doesnt-cause-it-183732">promote and reinforce these messages</a>.</p> <p>But this is <a href="https://bjsm.bmj.com/content/54/12/698">not based on evidence</a>. An emerging treatment known as <a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">cognitive functional therapy</a> aims to help patients undo some of these unhelpful and restrictive practices, and learn to trust and move their body again.</p> <h2>People are often given the wrong advice</h2> <p>People with chronic back pain are often referred for imaging scans to detect things like disc degeneration, disc bulges and arthritis.</p> <p>But these findings are very common in people <em>without</em> low back pain and research shows they <a href="https://pubmed.ncbi.nlm.nih.gov/24276945/">don’t accurately predict</a> a person’s current or future experience of pain.</p> <p>Once serious causes of back pain have been ruled out (such as cancer, infection, fracture and nerve compression), there is <a href="https://pubmed.ncbi.nlm.nih.gov/27745712/">little evidence</a> scan findings help guide or improve the care for people with chronic low back pain.</p> <p>In fact, scanning people and telling them they have arthritis and disc degeneration can <a href="https://pubmed.ncbi.nlm.nih.gov/33748882/">frighten them</a>, resulting in them avoiding activity, worsening their pain and distress.</p> <p>It can also lead to potentially harmful treatments such as <a href="https://pubmed.ncbi.nlm.nih.gov/27213267/">opioid</a> pain medications, and invasive treatments such as spine <a href="https://pubmed.ncbi.nlm.nih.gov/19127161/">injections</a>, spine <a href="https://pubmed.ncbi.nlm.nih.gov/12709856/">surgery</a> and battery-powered electrical stimulation of spinal nerves.</p> <h2>So how should low back pain be treated?</h2> <p>A complex range of factors <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">typically contribute</a> to a person developing chronic low back pain. This includes over-protecting the back by avoiding movement and activity, the belief that pain is related to damage, and negative emotions such as pain-related fear and anxiety.</p> <p>Addressing these factors in an individualised way is <a href="https://pubmed.ncbi.nlm.nih.gov/29573871/">now considered</a> best practice.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/15936976/">Best practice care</a> also needs to be person-centred. People suffering from chronic low back pain want to be heard and validated. They <a href="https://pubmed.ncbi.nlm.nih.gov/35384928/">want</a> to understand why they have pain in simple language.</p> <p>They want care that considers their preferences and gives a safe and affordable pathway to pain relief, restoring function and getting back to their usual physical, social and work-related activities.</p> <p>An example of this type of care is cognitive functional therapy.</p> <h2>What is cognitive functional therapy?</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">Cognitive functional therapy</a> is about putting the person in the drivers’ seat of their back care, while the clinician takes the time to guide them to develop the skills needed to do this. It’s led by physiotherapists and can be used once serious causes of back pain have been ruled out.</p> <p>The therapy helps the person understand the unique contributing factors related to their condition, and that pain is usually not an accurate sign of damage. It guides patients to relearn how to move and build confidence in their back, without over-protecting it.</p> <p>It also addresses other factors such as sleep, relaxation, work restrictions and engaging in physical activity based on the <a href="https://www.restorebackpain.com/patient-journey">person’s preferences</a>.</p> <p>Cognitive functional therapy usually involves longer physiotherapy sessions than usual (60 minutes initially and 30-45 minute follow-ups) with up to seven to eight sessions over three months and booster sessions when required.</p> <h2>What’s the evidence for this type of therapy?</h2> <p>Our recent clinical trial of cognitive functional therapy, published in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00441-5/fulltext">The Lancet</a>, included 492 people with chronic low back pain. The participants had pain for an average of four years and had tried many other treatments.</p> <p>We first trained 18 physiotherapists to competently deliver cognitive functional therapy across Perth and Sydney over six months. We compared the therapy to the patient’s “usual care”.</p> <p>We found large and sustained improvements in function and reductions in pain intensity levels for people who underwent the therapy, compared with those receiving usual care.</p> <p>The effects remained at 12 months, which is unusual in low back pain trials. The effects of most recommended interventions such as exercise or psychological therapies are <a href="https://pubmed.ncbi.nlm.nih.gov/34580864/">modest in size</a> and tend to be of <a href="https://pubmed.ncbi.nlm.nih.gov/32794606/">short duration</a>.</p> <p>People who underwent cognitive functional therapy were also more confident, less fearful and had a more positive mindset about their back pain at 12 months. They also liked it, with 80% of participants satisfied or highly satisfied with the treatment, compared with 19% in the usual care group.</p> <p>The treatment was as safe as usual care and was also cost-effective. It saved more than A$5,000 per person over a year, largely due to increased participation at work.</p> <h2>What does this mean for you?</h2> <p>This trial shows there are safe, relatively cheap and effective treatments options for people living with chronic pain, even if you’ve tried other treatments without success.</p> <p><a href="https://www.restorebackpain.com/cft-clinicians">Access to clinicians</a> trained in cognitive functional therapy is currently limited but will expand as training is scaled up.</p> <p>The costs depend on how many sessions you have. Our studies show some people improve a lot within two to three sessions, but most people had seven to eight sessions, which would cost around A$1,000 (aside from any Medicare or private health insurance rebates). <!-- Below is The Conversation's page counter tag.

How the brain stops us learning from our mistakes – and what to do about it

<p>You learn from your mistakes. At least, most of us have been told so. But science shows that we often fail to learn from past errors. Instead, we are likely to keep repeating the same mistakes.</p> <p>What do I mean by mistakes here? I think we would all agree that we quickly learn that if we put our hand on a hot stove, for instance, we get burned, and so are unlikely to repeat this mistake again. That’s because our brains create a threat-response to the physically painful stimuli based on past experiences. But when it comes to thinking, behavioural patterns and decision making, we often repeat mistakes – such as being late for appointments, leaving tasks until the last moment or judging people based on first impressions.</p> <p>The reason can be found in the way our brain processes information and creates templates that we refer to again and again. These templates are essentially shortcuts, which help us make decisions in the real world. But these shortcuts, known as heuristics, can also make us repeat our errors.</p> <p>As I discuss in my book <a href="https://www.drpragyaagarwal.co.uk/sway-press">Sway: Unravelling Unconscious Bias</a>, humans are not naturally rational, even though we would like to believe that we are. Information overload is exhausting and confusing, so we filter out the noise.</p> <p>We only see parts of the world. We tend to notice things that are repeating, whether there are any patterns or not, and we tend to preserve memory by generalising and resorting to type. We also draw conclusions from sparse data and use cognitive shortcuts to create a version of reality that we implicitly want to believe in. This creates a reduced stream of incoming information, which helps us connect dots and fill in gaps with stuff we already know.</p> <p>Ultimately, our brains are lazy and it takes a lot of cognitive effort to change the script and these shortcuts that we have already built up. And so we are more likely to fall back on the same patterns of behaviours and actions, even when we are conscious of repeating our mistakes. This is called confirmation bias – our tendency to confirm what we already believe in, rather than shift our mindset to incorporate new information and ideas.</p> <p>We also often deploy “<a href="https://theconversation.com/is-it-rational-to-trust-your-gut-feelings-a-neuroscientist-explains-95086">gut instinct</a>” - an automatic, subconscious type of thinking that draws on our accumulation of past experiences while making judgements and decisions in new situations.</p> <p>Sometimes we stick with certain behaviour patterns, and repeat our mistakes because of an “<a href="https://www.sciencedirect.com/science/article/pii/S0014292121002786">ego effect</a>” that compels us to stick with our existing beliefs. We are likely to selectively choose the information structures and feedback that help us protect our egos.</p> <p>One experiment found that when people were reminded of their successes of the past, they were more likely to <a href="https://www.sciencedirect.com/science/article/abs/pii/S1057740815000728">repeat those successful behaviours</a>. But when they were conscious of or actively made aware of their failures from the past, they were less likely to overturn the pattern of behaviour that led to failure. So people were in fact still likely to repeat that behaviour.</p> <p>That’s because, when we think of our past failures, we are likely to feel down. And in those moments, we are more likely to indulge in behaviour that makes us feel comfortable and familiar. Even when we think carefully and slowly, our brains have a bias towards the information and templates we had used in the past, regardless of whether these resulted in errors. This is called the <a href="https://www.psychologytoday.com/gb/blog/mind-my-money/200807/familiarity-bias-part-i-what-is-it">familiarity bias</a>.</p> <p>We can learn from mistakes though. In one experiment, monkeys and humans had to watch noisy, moving dots on a screen and judge their net direction of movement. The researchers found that both slowed down after an error. The larger the error, the longer the post-error slowing, showing more information was being accumulated. However, the quality of this information <a href="https://www.eurekalert.org/news-releases/809286">was low</a>. Our cognitive shortcuts can force us to override any new information that could help prevent repeating mistakes.</p> <p>In fact, if we make mistakes while performing a certain task, “frequency bias” makes us likely to repeat them whenever we do the task again. Simplistically speaking, our brains start assuming that the errors we’ve previously made are the correct way to perform a task – creating a habitual <a href="https://link.springer.com/article/10.3758/pbr.15.1.156">“mistake pathway”</a>. So the more we repeat the same tasks, the more likely we are to traverse the mistake pathway, until it becomes so deeply embedded that it becomes a set of permanent cognitive shortcuts in our brains.</p> <p><strong>Cognitive control</strong></p> <p>It sounds bleak, so what can be done?</p> <p>We do have a mental ability that can override heuristic shortcuts, known as “cognitive control”. And there are some <a href="https://www.cell.com/neuron/fulltext/S0896-6273(21)00075-1">recent studies in neuroscience with mice</a> that are giving us a better idea of what parts of our brains are involved in that.</p> <p>Researchers have also <a href="https://www.cell.com/neuron/fulltext/S0896-6273(18)31007-9">identified two brain regions</a> with “self-error monitoring neurons” – brain cells which monitor errors. These areas are in the frontal cortex and appear to be part of a sequence of processing steps – from refocusing to learning from our mistakes.</p> <p>Researchers are exploring whether a better understanding of this could help with development of better treatments and support for Alzheimer’s, for example, as preserved cognitive control is crucial for <a href="https://www.frontiersin.org/articles/10.3389/fnagi.2020.00198/full">wellbeing in later life</a>.</p> <p>But even if we don’t have a perfect understanding of the brain processes involved in cognitive control and self-correction, there are simpler things we can do.</p> <p>One is to become more comfortable with making mistakes. We might think that this is the wrong attitude towards failures, but it is in fact a more positive way forward. Our society denigrates failures and mistakes, and consequently we are likely to feel shame for our mistakes, and try and hide them.</p> <p>The more guilty and ashamed we feel, and the more we try and hide our mistakes from others, the more likely we are to repeat them. When we not feeling so down about ourselves, we are more likely to be better at taking on new information that can help us correct our mistakes.</p> <p>It can also be a good idea to take a break from performing a task that we want to learn how to do better. Acknowledging our failures and pausing to consider them can help us reduce frequency bias, which will make us less likely to repeat our mistakes and reinforce the mistake pathways.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/how-the-brain-stops-us-learning-from-our-mistakes-and-what-to-do-about-it-203436" target="_blank" rel="noopener">The Conversation</a>. </em></p>

3 ways your brain changes with ageing

<p dir="ltr">Your entire body changes when you age, including your brain, which is responsible for everything. Regardless of your physical or neurological health, there is such a thing as “cognitive ageing.” It happens to the best of us!</p> <p dir="ltr">So, what are these changes? </p> <p dir="ltr" role="presentation"><strong>1. Processing speed</strong></p> <p dir="ltr">This refers to how quickly the brain can process information and provide a response.

Memory</strong></p> <p dir="ltr">Memory is complex, and there’s different kinds of memory, but these are the functions that you’ll notice changes in as you age:</p> <ul> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Working memory, the ability to hold information and manipulate it mentally, declines </p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Episodic memory, the ability to remember personally experienced events at a certain plane or time, declines </p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Prospective memory, the ability to remember to do things in the future, declines</p> </li> </ul> <p dir="ltr"><strong>3.

Long COVID: How lost connections between nerve cells in the brain may explain cognitive symptoms

<p>For a portion of people who get COVID, symptoms continue for <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/conditionsanddiseases/bulletins/prevalenceofongoingsymptomsfollowingcoronaviruscovid19infectionintheuk/6october2022" target="_blank" rel="noopener">months or even years</a> after the initial infection. This is commonly referred to as “long COVID”.</p> <p>Some people with long COVID complain of “<a href="https://theconversation.com/what-is-and-what-isnt-brain-fog-190537" target="_blank" rel="noopener">brain fog</a>”, which includes a wide variety of cognitive symptoms affecting memory, concentration, sleep and speech. There’s also growing concern about findings that people who have had COVID are at <a href="https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(22)00260-7/fulltext" target="_blank" rel="noopener">increased risk</a> of developing brain disorders, such as dementia.</p> <p>Scientists are working to understand how exactly a COVID infection affects the human brain. But this is difficult to study, because we can’t experiment on living people’s brains. One way around this is to create <a href="https://www.nature.com/articles/s41578-021-00279-y" target="_blank" rel="noopener">organoids</a>, which are miniature organs grown from stem cells.</p> <p>In a <a href="https://www.nature.com/articles/s41380-022-01786-2.pdf" target="_blank" rel="noopener">recent study</a>, we created brain organoids a little bigger than a pinhead and infected them with SARS-CoV-2, the virus that causes COVID-19.</p> <p>In these organoids, we found that an excessive number of synapses (the connections between brain cells) were eliminated – more than you would expect to see in a normal brain.</p> <p>Synapses are important because they allow neurons to communicate with each other. Still, the elimination of a certain amount of inactive synapses is part of normal brain function. The brain essentially gets rid of old connections when they’re no longer needed, and makes way for new connections, allowing for more efficient functioning.</p> <p>One of the crucial functions of the brain’s immune cells, or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5768411/" target="_blank" rel="noopener">microglia</a>, is to prune these inactive synapses.</p> <p>The exaggerated elimination of synapses we saw in the COVID-infected models could explain why some people have cognitive symptoms as part of long COVID.</p> <p><strong>Parallels with neurodegenerative disorders</strong></p> <p>Interestingly, this pruning process is believed to go awry in several disorders affecting the brain. In particular, excessive elimination of synapses has recently been linked to <a href="https://www.nature.com/articles/s41593-018-0334-7" target="_blank" rel="noopener">neurodevelopmental disorders</a> such as <a href="https://www.nature.com/articles/s41593-018-0334-7" target="_blank" rel="noopener">schizophrenia</a>, as well as <a href="https://www.frontiersin.org/articles/10.3389/fncel.2019.00063/full" target="_blank" rel="noopener">neurodegenerative disorders</a> such as Alzheimer’s and Parkinson’s disease.</p> <p>By sequencing the RNA of single cells, we could study how different cell types in the organoid responded to the virus. We found that the pattern of genes turned on and off by the microglia in our COVID-infected organoids mimicked changes seen in neurodegenerative disorders.</p> <p>This may go some way in explaining the link between COVID and the risk of developing certain neurological disorders.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=425&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=425&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/491380/original/file-20221024-17-9wi5pg.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=425&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="caption">A brain organoid used in our study.

In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6410571/">other research</a>, we’ve observed that an antibiotic called minocycline can reduce the degree to which microglia prune synapses in a dish. So we want to see if this drug can help in our brain organoid models following SARS-CoV-2 infection.<!-- Below is The Conversation's page counter tag.

High score: Video game play linked to better cognitive performance

<p>Children playing video games for more than three hours a day score better on cognitive performance compared to non-gamers.</p> <p>A study involving more than 1,800 children aged nine and ten by researchers at the University of Vermont in the United States, is believed to be the largest investigation looking at the association between <a href="https://cosmosmagazine.com/people/good-games/" target="_blank" rel="noreferrer noopener">video games</a>, cognition and brain function. </p> <p>The researchers found children who played more than 21 hours of video games per week recorded better scores for <a href="https://cosmosmagazine.com/technology/can-games-tell-if-you-are-impulsive/" target="_blank" rel="noreferrer noopener">response inhibition</a> and working memory than those who never played. The article is <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2797596?utm_source=For_The_Media&amp;utm_medium=referral&amp;utm_campaign=ftm_links&amp;utm_term=102422" target="_blank" rel="noreferrer noopener">published</a> in JAMA Network Open.</p> <p>Lead author Dr Bader Chaarani told Cosmos, “it makes sense that if you consider the brain is like a muscle, the more you train it, the better it performs.” </p> <p>Impulse control is considered important as it is linked to substance use in adolescence, while working memory is connected to IQ and language processing, Chaarani says.</p> <p>In the study, the children performed two tasks inside an MRI scanner. The first was a ‘stop signal task’ measuring impulse control. The task required children to press a button when arrows pointed left or right, but not press anything when the arrows point up. The second, a working memory task showed children pictures of faces and tested their recall.</p> <p>Children were also tested outside the scanner using oral and verbal tasks.</p> <p>In contrast to the findings of other research, the study did not find any significant difference between gamers and non-gamers in terms of mental health or behaviour. </p> <div class="newsletter-box"> <div id="wpcf7-f6-p220302-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/high-score-video-game-play-linked-to-better-cognitive-performance/#wpcf7-f6-p220302-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>Chaarani says, “many parents today are concerned about the effects of video games on their children’s health and development, and as these games continue to proliferate among young people, it is crucial that we better understand both the positive and negative impact that such games may have.”</p> <p>In Australia, 78% of children and teenagers play video games, averaging 106 minutes per day, according to <a href="https://igea.net/wp-content/uploads/2021/10/DA22-Report-FINAL-19-10-21.pdf" target="_blank" rel="noreferrer noopener">research commissioned</a> by the Interactive Games and Entertainment Association.</p> <p>In the University of Vermont study, non-video gamers (who spent zero hours a week playing games) and gamers (who played more than 21 hours a week) were recruited from a mix of 21 public, private and charter schools across the United States.</p> <p>The two groups did not differ in terms of characteristics such as age, BMI or IQ. However, the gamers group had a higher share of boys, and lower parental income on average.</p> <p>The research forms part of the <a href="https://abcdstudy.org" target="_blank" rel="noreferrer noopener">Adolescent Brain Cognitive Development Study</a>, the largest long-term study of brain development and child health in the United States. This allows children to be tracked over time into early adulthood to see if changes in video gaming behaviour are linked to changes in cognitive skills, brain activity, behaviour, and mental health.</p> <p>While the results showed an association between playing video games and higher cognitive performance, the paper notes it does not evidence for causality. This will be the focus of further research, given the Adolescent Brain Cognitive Development Study follows children every two years.</p> <p>Chaarani says they also plan to look at the effect of video game genre in future work. The current study did not differentiate by the type of video games children played, whether puzzle games, action adventure, sports, simulation or shooters; or single versus multi-player games. </p> <p>“There are some smaller studies reporting that different types of games may engage different areas in the brain, different functions of the brain… but because of the sample size we cannot trust them enough,” he says.</p> <p>“For the nine and ten years old, we’ve been looking at surveys done internationally. So, these kids tend to play more fast-paced games like action, adventure and shooters that give you immediate reward rather than slow paced games.”</p> <p><!-- Start of tracking content syndication.

Your dog can get dementia - here’s how to prevent it

<p dir="ltr">Just like us, dogs can experience cognitive decline as they age. They can also risk developing a neurodegenerative condition called Canine Cognitive Dysfunction (CCD), a condition similar to Alzhheimer’s Disease.</p> <p dir="ltr">Like Alzheimer’s, symptoms dogs with CCD can experience include a loss of spatial awareness, memory deficiencies, disrupted sleep, and altered social interactions.</p> <p dir="ltr">Both CCD and Alzheimer’s also share symptoms found in the brain itself, including <a href="https://oversixty.com.au/health/mind/alzheimer-s-marker-found-in-the-brain" target="_blank" rel="noopener">the buildup of fragments of a protein called beta-amyloid</a> in between nerve cells.</p> <p dir="ltr">According to a new study published in the journal <em><a href="https://doi.org/10.1038/s41598-022-15837-9" target="_blank" rel="noopener">Scientific Reports</a></em>, the risk of developing CCD increases by 68 percent each year after dogs turn 10.</p> <p dir="ltr">The team studied a whopping 15,019 dogs that took part in a longitudinal study called the Dog Ageing Project. Between 2019 and 2020, the owners of participating pets completed two surveys about the health status and physical activity of their dogs. They also completed the Canine Social and Learned Behaviour survey, which tested for symptoms of CCD such as dogs failing to recognise familiar people.</p> <p dir="ltr">But, they also found that older pooches that were very active had a much smaller risk of developing the condition in comparison to less active dogs of the same breed and health - with the more sedentary dogs having a 6.47 times higher risk of having CCD.</p> <p dir="ltr">They stress that their study doesn’t show that a lack of physical activity causes CCD, and are calling for more research to determine whether CCD is caused by less physical activity or if the inactivity is caused by CCD.</p> <p dir="ltr">Because of the similarities between CCD and Alzheimer’s disease, the team argue that means that researching CCD could have implications for our understanding and treatment of Alzheimer’s, and vice versa.</p> <p dir="ltr">For example, the association between physical activity and lower risks of CCD come after numerous studies showing this relationship in rodents <a href="https://oversixty.com.au/health/mind/the-surprising-reason-exercise-improves-symptoms-of-alzheimer-s" target="_blank" rel="noopener">and in humans</a>.</p> <p dir="ltr">“These observations may reflect a variety of biologic mechanisms, including a reduction of pro-inflammatory cytokines in the brain that otherwise contribute to neural damage and death, and an increase in neural plasticity,” they write of the studies with rodents and people, adding that these mechanisms might also explain the link between physical activity and CCD risk.</p> <p dir="ltr">“Given increasing evidence of the parallels between canine and human cognitive disease, accurate CCD diagnosis in dogs may provide researchers with more suitable animal models in which to study ageing in human populations.”</p> <p><span id="docs-internal-guid-91437cc1-7fff-5a43-0a9a-bca582c47473"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Vitamin C deficiency linked to cognitive impairment

<p dir="ltr">A new study has found a link between poor brain function and how much Vitamin C older people have, and that a deficiency could have some serious effects on the brain.</p> <p dir="ltr">Cognitive impairment is common among older, hospitalised patients, and can result in poor memory and concentration, as well as finding decision-making difficult.</p> <p dir="ltr">The team from Flinders University in Adelaide tested the cognitive function and vitamin C level of 160 people over the age of 75 who were admitted to the university’s medical centre.</p> <p dir="ltr">From this, 91 patients were found to have cognitive impairment, and 42 of this group were found to have such low levels of vitamin C - below 11 micromoles per litre - they were at risk of developing scurvy.</p> <p dir="ltr">“Our findings showed that cognitive function scores were significantly lower among patients who were vitamin C deficient, with further analysis suggesting vitamin C deficiency was almost three times more likely to be associated with cognitive impairment after adjustment for other factors,” Associate Professor Yogesh Sharma, the study’s lead author, <a href="https://www.scimex.org/newsfeed/low-vitamin-c-linked-to-cognitive-impairment-in-older-australians" target="_blank" rel="noopener">said</a>.</p> <p dir="ltr">The researchers stressed that the two were associated, not that vitamin C deficiency causes cognitive impairment.</p> <p dir="ltr">They also noted that many of the symptoms of low vitamin C levels - including skin issues, bruising and bleeding - are common in this age group because of a number of conditions.</p> <p dir="ltr">“It may, therefore, be difficult to diagnose vitamin C deficiency solely on looking for these particular symptoms in older hospitalised patients,” Associate Professor Sharma said.</p> <p dir="ltr">“Given we know vitamin C deficiency is common among older hospitalised patients, medical professionals need to remain vigilant for this condition and confirm a patient’s vitamin C status in suspected cases.”</p> <p dir="ltr">With this link, the researchers said they will need to conduct more studies to confirm the link and determine whether replacing a patient’s vitamin C levels could help prevent or reverse cognitive impairment.</p> <p dir="ltr">The study was published in the journal <em><a href="https://doi.org/10.3390/antiox11030463" target="_blank" rel="noopener">Antibiotics</a></em>.</p> <p><span id="docs-internal-guid-2ab5757b-7fff-e419-e985-eb63d06eb2d3"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Air pollution may impair cognitive function

<div> <div class="copy"> <p>A joint China-US research team has found that exposure to even short-term air pollution may impair cognitive function.</p> <p>Air pollution is a growing cause of sickness and death globally, with a <a href="https://cosmosmagazine.com/climate/air-pollution-pandemic-warning/" target="_blank" rel="noreferrer noopener">recent study</a> estimating that it caused an extra 8.8 million premature deaths in 2015, surpassing the 7.2 million caused by tobacco smoking. It has well-established effects on the lungs and the heart – it has been linked with spikes in <a href="http://jaha.ahajournals.org/content/5/5/e002742" target="_blank" rel="noreferrer noopener">heart attacks, strokes</a> and <a href="http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0180522" target="_blank" rel="noreferrer noopener">asthma</a>, and is a carcinogen known to cause lung cancer.</p> <p>Increasingly, research is also associating air pollution with other health impacts including <a href="https://cosmosmagazine.com/biology/kidney-disease-linked-to-air-pollution/" target="_blank" rel="noreferrer noopener">kidney disease</a>, <a href="https://cosmosmagazine.com/climate/could-air-pollution-contribute-to-psychiatric-illness/" target="_blank" rel="noreferrer noopener">psychiatric illness</a> and <a href="https://cosmosmagazine.com/biology/air-pollution-link-to-alzheimer-s-mooted/" target="_blank" rel="noreferrer noopener">Alzheimer’s</a>.</p> <p><strong>What causes air pollution?</strong></p> <ul> <li>Air pollution is the release of pollutants into the air that have detrimental effects on human or planetary health.</li> <li>It can have natural sources, such as desert dust or bushfire smoke, but is increasingly created by humans, primarily from burning fossil fuels.</li> <li>There are two main types: smog occurs when emissions from burning fossil fuels react with sunlight, while soot is made up of tiny particles made up of smoke, soil, dust, allergens or chemicals. Anything that combusts fossil fuels can cause this, including vehicle exhaust, power plants, incinerators and more.</li> </ul> <p>Now, in a new study <a href="https://doi.org/10.1038/s43587-021-00060-4" target="_blank" rel="noreferrer noopener">published</a> in the journal <em>Nature Ageing</em>, researchers have linked poor air quality with decreased brain health.</p> <p>The team studied a sample of 954 Caucasian males (with an average age of 70) from the Boston area in the US, who were participants in the Veterans Affairs Normative Aging Study. Their cognitive function was measured by a series of assessments to test their attention, learning and memory, as well as an screening to help detect early signs of dementia.</p> <p>This was compared to the average levels of fine particulate matter (PM2.5, smaller than 2.5 micrometres in size) in the area, both on the day of each test and in the 28 days prior. The team found the participants tended to score lower when levels of PM2.5 were higher in the month before the tests – even when levels were still below what is considered as “hazardous”.</p> <p>“The findings were quite startling,” write cognitive health researchers Joanne Ryan and Alice J. Owen, in an <a href="https://dx.doi.org/10.1038/s43587-021-00062-2" target="_blank" rel="noreferrer noopener">accompanying article</a>. “Even relatively small increases in the levels of PM2.5 in the 3–4 weeks prior to testing were associated with consistently worse cognitive performance.”</p> <p>Ryan and Owen, both from Monash University in Australia and both not involved in the study, point out that Boston “has by no means the worst air quality in the USA or the world, and yet significant detrimental effects of air pollution on cognitive function were observed”.</p> <p>While a decline in brain function in older adults is common, it can be exacerbated – and accelerated – by environmental factors. Evidence is <a href="https://doi.org/10.3233/jad-180631" target="_blank" rel="noreferrer noopener">mounting</a> that air pollution could be a risk factor for dementia and could, over the long term, be <a href="https://dx.doi.org/10.1016%2Fj.neuro.2016.06.004" target="_blank" rel="noreferrer noopener">associated</a> with cognitive declines.</p> <p>“The results of the current study are especially important because they provide some of the first evidence that even relatively low-level, short-term increases in PM2.5 are detrimental for thinking and memory, as well as global cognition in older adults,” Ryan and Owen write.</p> <p>The results may point to a general trend in the larger population, given that air pollution <a href="https://www.unicef.org/environment/files/Danger_in_the_Air.pdf" target="_blank" rel="noreferrer noopener">affects brain development</a> in kids, and women seem to be <a href="https://doi.org/10.1289/ehp.0900994" target="_blank" rel="noreferrer noopener">more strongly affected</a> than men.</p> <p>Interestingly, the researchers also found that the participants who were prescribed NSAIDs (nonsteroidal anti-inflammatory drugs, such as aspirin) were less adversely affected. This may be because the health impacts of air pollution tend to involve activating the body’s inflammatory response. But caution is warranted; there may be many other differences between participants who do and don’t use NSAIDs.</p> <p>This study also had a relatively small sample size and focused on a certain geographical area, so further research is needed to solidify the link between air pollution and cognitive function.</p> <p>However, Ryan and Owen emphasise the importance of the results.</p> <p>“The implications for public health, and consequent health, societal and economic costs of air pollution, are immense,” they write. “This should be a further wake-up call about the urgent need for action.</p> <p>“It has been estimated that 90% of the world’s population breathe polluted air. Breathing clean air is fundamental to our health but represents a global challenge and one of substantial inequity, disproportionally affecting the most vulnerable.”</p> <p><em>Image credits: Getty Images</em></p> <p><em><!-- Start of tracking content syndication.

Why the use of cash is rapidly declining

<p dir="ltr">When was the last time you used cash to pay for something? Do you even have cash in your wallet right now? </p> <p dir="ltr">The way we pay has drastically changed over the past few years with so many new options available, such as buy-now-pay-later and contactless payments. </p> <p dir="ltr">According to the annual <a href="https://worldpay.globalpaymentsreport.com/en" target="_blank" rel="noopener">Global Payments Report</a>, cash payments in Australia will amount to just two per cent of transactions by 2025. </p> <p dir="ltr">The report also predicts that digital wallets that are readily available with just two clicks on a smartphone, will be the preferred method of payment in just two years. This will overtake the use of credit and debit cards. </p> <p dir="ltr">About 40 per cent of transactions across the country are composed of debit cards, following closely with credit cards at 35 per cent, digital wallets sitting at 11 per cent, cash seven percent, and buy-now-pay-later options at a mere four per cent.  </p> <p dir="ltr">Thanks to Covid-19 and periods of lockdown, most Aussies opted out of using cash, with the Australian Banking Association reporting a decline in use of ATMs by 20 per cent. </p> <p dir="ltr">"Covid-19 accelerated trends in our society and changed the way we live our lives. Working from home will forever be more prominent within the workforce, we have steered away from using cash and as a result are seeing an increase in card and technology payments and the existing trend of doing banking online instead of in a branch has only continued," ABA chief executive Anna Bligh told <a href="https://www.9news.com.au/national/australia-cash-use-declining-predicted-to-be-two-per-cent-value-in-2025/29a6febb-f8ab-49cf-9462-56fd20a22a33" target="_blank" rel="noopener">Nine News</a>.</p> <p dir="ltr">"As we have seen more people go away from using branches, it's no surprise to see banks invest in areas where customers prefer to bank, such as in their online platforms and apps.”</p> <p dir="ltr">The ABA also showed that one in 10 Aussies regularly leaves their home without their wallet, while more than one in three use digital wallets weekly. </p> <p dir="ltr"><em>Image: Shutterstock</em></p>

Feel alone in your eco-anxiety? Don’t – it’s remarkably common to feel dread about environmental decline

<p>Feeling anxious about the ecological crises we face is entirely understandable, given the enormity of the threats.</p> <p>Eco-anxiety is <a href="https://www.bbc.co.uk/bbcthree/article/b2e7ee32-ad28-4ec4-89aa-a8b8c98f95a5">sometimes described</a> as a mental health problem. It’s not. Eco-anxiety is a rational psychological and emotional response to the overlapping ecological crises we now face.</p> <p>If you feel this way, you are not alone. We have found eco-anxiety is remarkably common. Almost two-thirds of Australian participants in <a href="https://www.sciencedirect.com/science/article/pii/S0959378021001709">our recent surveys</a> reported feeling eco-anxiety at least “some of the time”.</p> <p>The response <a href="https://www.nature.com/articles/d41586-021-02862-3">can be triggered by media stories</a> on environmental and climate crises as well as human efforts to combat them. This includes the barrage of media from the United Nations climate conference, or COP26, now underway in Glasgow.</p> <p>In this age of ecological reckoning, eco-anxiety is not going to go away. That means we must learn how to cope with it – and perhaps even harness it to drive us to find solutions</p> <p><a href="https://images.theconversation.com/files/430117/original/file-20211104-17-1846nze.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/430117/original/file-20211104-17-1846nze.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Cleared area of rainforest" /></a> <span class="caption">Awareness of environmental crises like deforestation can provoke anxiety.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Dwelling on problems we contribute to</h2> <p>Our study found four key features of eco-anxiety:</p> <ol> <li><strong>affective symptoms</strong>, such as feelings of anxiety and worry</li> <li><strong>rumination</strong>, meaning persistent thoughts which can keep you up at night</li> <li><strong>behavioural symptoms</strong>, such as difficulty sleeping, working, studying or socialising</li> <li><strong>anxiety</strong> about your personal impact on the planet.</li> </ol> <p>We found similar levels of eco-anxiety in our surveys of 334 Australians and 735 New Zealanders, with people affected in similar ways in both countries. This supports <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3918955">emerging research</a>, which found more than half of young people surveyed across ten countries experienced climate anxiety. Feeling anxious about the state of the planet is likely to be universal.</p> <p>When we asked Australians how it affected them, they told us eco-anxiety affected everything from their mood to their daily routine to their relationships. It even affected their ability to concentrate, work or study. For some, eco-anxiety made them feel restless, tense and agitated. New Zealanders reported similar impacts.</p> <p>Our study found people were also anxious about their personal contribution to the deteriorating state of the planet. Some participants noted the state of the planet made them “extremely anxious”, so much so they “find it hard to think about anything else”.</p> <p>Other research shows many people are anxious about how their personal behaviours impact the earth, such as <a href="https://www.ucpress.edu/book/9780520343306/a-field-guide-to-climate-anxiety">consumerism or flying</a>. Some young adults are choosing to have fewer children, or none at all, out of concern their children will contribute to the climate crisis or will <a href="https://nymag.com/intelligencer/2019/02/book-excerpt-the-uninhabitable-earth-david-wallace-wells.html">inherit a degraded world</a>.</p> <p>These fears appeared in our study too, with one parent participant noting:</p> <blockquote> <p>My biggest worry is that climate change will affect my child in their lifetime, and I get very upset that I won’t be able to protect him from the effects of it.</p> </blockquote> <h2>Is eco-anxiety different to generalised anxiety?</h2> <p>Eco-anxiety has similarities with generalised anxiety and stress, but we found important differences, such as the focus on environmental issues and our contribution to the problem.</p> <p>We also found people experience eco-anxiety independent of depression, anxiety and stress, suggesting it’s a unique experience.</p> <p>While it is possible to experience eco-anxiety as someone who is otherwise mentally well, many people experience it on top of <a href="https://link.springer.com/article/10.1007%2Fs12144-021-01385-4">existing mental health issues</a>.</p> <p>What we need to do now is understand what eco-anxiety means for individual (and planetary) well-being, and <a href="https://www.tandfonline.com/doi/full/10.1080/02650533.2020.1844166">provide support</a> to people with varying degrees of this anxiety.<a href="https://images.theconversation.com/files/429905/original/file-20211103-19-pt7tvl.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/429905/original/file-20211103-19-pt7tvl.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="School students carrying posters calling for climate action" /></a> <span class="caption">School students marching for climate action in the UK, 2019.</span> <span class="attribution"><a href="https://www.shutterstock.com/image-photo/london-uk-united-kingdom-15th-february-1315212515" class="source">Shutterstock</a></span></p> <h2>Four ways to cope with your eco-anxiety</h2> <p>Eco-anxiety is not going to go away as an issue, given the range of environmental issues the world is confronting. To stop these feelings becoming overwhelming or debilitating, there are a range of <a href="https://psychology.org.au/getmedia/cf076d33-4470-415d-8acc-75f375adf2f3/coping_with_climate_change.pdf.pdf">behavioural, cognitive and emotional strategies</a> people can use to cope.</p> <p>Here are four techniques:</p> <ol> <li> <p><strong>validation</strong> One part of managing your own anxiety is to <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618520300773">validate it</a>, by acknowledging it makes sense to feel anxious and distressed</p> </li> <li> <p><strong>time out</strong> Another technique is to take mental breaks and avoid your 24/7 news feed to give yourself time to restore a sense of balance</p> </li> <li> <p><strong>seek hope</strong> Cultivating a <a href="https://www.sciencedirect.com/science/article/pii/S0272494412000138?casa_token=mIMzMUtEHZYAAAAA:VHVA59QmgjLMGuMr8n-gb4aCxYKO3OrC-ym8UViPw14R1OBZymnfoW4dmQYsw7FHvvWv2T_J4w">realistic sense of hope</a> about the future can also reduce anxiety emerging from our awareness of ecological threats. That means appreciating the complexity of the problem, while also searching for alternative visions of the future and trusting that we, as a collective, will eventually resolve the crisis before it’s too late</p> </li> <li> <p><strong>take action</strong> Many of us struggle with a sense of overwhelming powerlessness in the face of a deteriorating climate. This can be self-reinforcing. To combat this, you can try action - whether changing your own behaviour or getting involved in campaigns.</p> </li> </ol> <p>As climate campaigner Greta Thunberg <a href="https://www.penguin.co.uk/articles/2019/jul/young-climate-activists-on-greta-thunberg-and-climate-crisis.html">has said</a>, “no one is too small to make a difference”.</p> <p>Climate change has been described as the <a href="https://www.sciencedirect.com/science/article/pii/S0959378018313608?casa_token=W-MRkMOq8DoAAAAA:o81eFiIQ6_82L9CGUP-WDIN9zEtq8cdgQSIUqqsqhH2QXaaHPF4X_bOSXJ4F7qNFmtY05REbfQ">greatest collective action problem</a> we have ever faced. That means the necessary changes will have to come from the collective action of all individuals, industries and governments.

But being concerned about environmental crises does not need to come at the <a href="https://www.ucpress.edu/book/9780520343306/a-field-guide-to-climate-anxiety">cost of your health</a> and wellbeing.</p> <p>After all, psychological, emotional and behavioural burnout is not helpful for you – or the planet.<!-- Below is The Conversation's page counter tag.

Queen Elizabeth declines Oldie of the Year Award

<p><span style="font-weight: 400;">If you have ever seen an optical illusion and wondered why you may have been tricked by it, you’re not the only one.</span></p> <p><span style="font-weight: 400;">Researchers interested in cognitive science and visual perception have used optical illusions to see how our brain works - even when we’re not being amazed or tricked by a deceptive image.</span></p> <p><span style="font-weight: 400;">“Illusions help us understand the rules our brain uses to create reality, based on the input it receives from our senses,” says Mark Williams, an honorary professor of cognitive science at Macquarie University.</span></p> <p><span style="font-weight: 400;">“What we actually see or hear or feel or taste or smell isn’t actually what’s out there, but what we think is out there.</span></p> <p><span style="font-weight: 400;">“Because we don’t see the world as it actually is, illusions help explain to us how we are creating the world we actually perceive.”</span></p> <p><span style="font-weight: 400;">This means that our brains don’t see the world wholly, instead responding to everything it perceives and filtering out what it doesn’t think is important.</span></p> <p><span style="font-weight: 400;">“Our sensory systems respond to the sum of all contextual information in which the relative information is more important than the absolute,” says Dr Spehar, a psychologist from the University of New South Wales</span></p> <p><span style="font-weight: 400;">“So for example, you perceive colour relative to the background, or you see orientation relative to the frame of reference.</span></p> <p><span style="font-weight: 400;">Let’s put our perceptions of reality to the test with this multicoloured illusion.</span></p> <p><strong>Is it moving?</strong></p> <p><img style="width: 500px; height:375.2900232018562px;" src="https://oversixtydev.blob.core.windows.net/media/7843585/109a9c3cc8949eb4a12d252545fb759c.jpg" alt="" data-udi="umb://media/9693caf172e54a1e8d66f94106e45659" /></p> <p><em><span style="font-weight: 400;">Image: Wikimedia Commons</span></em></p> <p><span style="font-weight: 400;">Though this image appears to move, staring at the centre of the image makes it stop.</span></p> <p><span style="font-weight: 400;">This illusion, known as rotating snakes, triggers receptors in your eyes that detect movement in your peripheral vision.</span></p> <p><span style="font-weight: 400;">Dr Spehar says that though we don’t fully know how the illusion works, it appears to involve the differences in contrast between the black, white, and coloured areas.</span></p> <p><span style="font-weight: 400;">“The illusion has a lot of light and dark elements, of both high and low contrast scattered everywhere,” Dr Spehar says.</span></p> <p><span style="font-weight: 400;">“[These] stimulate motion-sensitive neurons in the periphery of our visual field.”</span></p> <p><span style="font-weight: 400;">Even when you blink or move your eyes, parts of the illusion are projected onto different parts of your eye, meaning that it appears to move in a clockwise or counterclockwise movement.</span></p> <p><em><span style="font-weight: 400;">Image: Wikimedia Commons</span></em></p>

COVID accelerates worrying decline in young people’s mental health

<p>We <a href="https://ourlives.org.au/project-overview/">have been following</a> more than 2,000 Queenslanders from their adolescence into adulthood. The aim of the Our Lives study is to investigate how young people think about their future and how they master their trajectories in a world of rapid change and uncertainty.</p> <p>In 2006, our research team began tracking more than 7,000 students who began high school in Queensland at the age of 13. Since then, the study has become the largest and longest of school leavers in Australia post the global financial crisis. The cohort turns 27 this year.</p> <p>Every two years, we survey this cohort about their developing aspirations and experiences in work, study, housing, relationships and family. We also explore changes in their social attitudes and mental and physical health.</p> <p>We did a <a href="https://ourlives.org.au/wp-content/uploads/2020/06/4755-Our-Lives-Infographic.png">special survey in June 2020</a> in response to COVID-19. We wanted to understand how the cohort had been affected since the previous survey six months earlier, in late 2019.</p> <p><strong>How different demographics have fared</strong></p> <p>Research has indicated <a href="https://theconversation.com/young-women-are-hit-doubly-hard-by-recessions-especially-this-one-140943">women are more adversely affected</a> than men by recessions, both economically and psychologically.</p> <p>In line with this, the female participants in our study displayed significantly worse mental health during COVID than their male counterparts. The proportion of 27 year old males who described their mental health as excellent, very good or good in June 2020 was 70.5% compared to 63.5% for females.</p> <p>Young adults living in major city areas, where COVID cases have largely been concentrated, experienced a decline in mental health — from 68.7% in 2019 to 62.2% in 2020. But the proportion of those living in rural areas actually rose from 70.9% in 2019 to 72.2% in 2020.</p> <p>By their mid-twenties, a major gap emerged in the well-being of people with and without secure work. In 2015, when participants were 22 years old, 82.4% with permanent, ongoing work rated their mental health good to excellent, compared to 68.5% in 2020. The results were 77.6% in 2015 for those who were unemployed compared to 54.1% in 2020.</p> <p>Emergency welfare measures, such as the JobKeeper wage subsidy and increase to JobSeeker, may have temporarily prevented this gap from widening.</p> <p>One of Australia’s top mental health experts, Professor Ian Hickie, <a href="https://www.theguardian.com/commentisfree/2020/oct/09/we-need-more-than-hope-and-optimism-to-tackle-australias-mental-health-crisis">has argued</a> an extension to JobKeeper and greater financial support for students in post-school education and training are critical for mitigating the predicted surge in youth mental illness.</p> <p><strong>What about relationships?</strong></p> <p>Security in young adults’ housing and relationships appears to provide a key buffer against the negative psychological impacts of COVID-19. Our data show young adults living out of home, or with a partner (married or de facto) report substantially better mental health in June 2020 than those who are single and living with parents.</p> <p>Young people in who were living with housemates during the COVID-19 period experienced the sharpest decline in positive mental health.</p> <p>Social distancing took its toll on the Our Lives cohort during the national restriction period, with 39% reporting feelings of loneliness or isolation. There were also signs of strain and conflict in the young people’s relationships with those in their household.</p> <p>Around one-quarter of the sample reported a lack of personal space or alone time, while 16% reported experiencing greater tension and conflict in the household. These outcomes increased young adults’ chances of experiencing a major decline in mental health during the lockdown period.</p> <p>However, the effects of stay-at-home restrictions were not inherently negative. For many young adults, restrictions provided more time for themselves (38%) and encouraged stronger relationships with partners or family (33%). These outcomes were associated with significantly lower chances of a decline in mental health.</p> <p>It’s vital young people have good access to youth mental health services in the months ahead so their mental health doesn’t continue to drastically decline. This is particularly the case for young people who may be less able to turn to parents, partners or friends for help.</p> <p>Research has consistently found young people with mental health issues are the <a href="https://pubmed.ncbi.nlm.nih.gov/19530018/">least likely</a> to seek out mental health information and access professional help when they need it.</p> <p>There is hope that the collective experience of social distancing during COVID-19 may have <a href="https://www.theaustralian.com.au/breaking-news/aussies-prepared-to-get-more-mental-health-help-than-ever-during-covid19-reducing-stigma/news-story/213b772b22e5479e81f8a5a607776ef0">helped reduce some of the stigma</a> associated with seeking help. If this is the case, we must seize the opportunity to learn from the experience of the young people in our cohort and the Australians they represent.</p> <p><em>For mental health, go to <a href="https://www.lifeline.org.au/">Lifeline Australia</a> on 13 11 14 or <a href="https://www.beyondblue.org.au/">Beyond Blue</a> 1300 22 4636</em></p> <p><em>Written by <a href="https://theconversation.com/profiles/zlatko-skrbis-126879">Zlatko Skrbis</a>, Australian Catholic University; <a href="https://theconversation.com/profiles/jacqueline-laughland-booy-191894">Jacqueline Laughland-Booy</a>, Australian Catholic University, and <a href="https://theconversation.com/profiles/jonathan-smith-1072199">Jonathan Smith</a>, Australian Catholic University.

How the decline in Chinese tourists around the world has hit the luxury sector

<p>Large groups of Chinese visitors have become a pillar of the global tourism industry. Coronavirus has not only put paid to this enormous source of income for major cities and sights around the world, it is having a massive knock-on effect for the luxury goods business.</p> <p>For any tourist, buying souvenirs is a key part of the holiday experience. They might be trinkets such as key rings or fridge magnets, a T-shirt emblazoned with the slogan “I ❤ NY” or a Russian matryoshka doll. But a significant number of Chinese tourists prefer to spend large sums on luxury items, such as designer clothes and accessories, when they travel overseas.</p> <p>Roughly one-third of global spending on luxury goods was credited <a href="https://www.voguebusiness.com/consumers/chinese-consumers-luxury-purchases-growth-bain">to Chinese consumers in 2018</a>. Consultants at Bain predict this <a href="https://jingdaily.com/bain-company-chinese-consumers-will-make-up-half-of-global-luxury-purchases-by-2025/">to rise to 50% by 2025</a>. Before the coronavirus pandemic, nearly all of this £85 billion worth of spending (92%) was done <a href="https://www.mckinsey.com/~/media/mckinsey/featured%20insights/china/how%20young%20chinese%20consumers%20are%20reshaping%20global%20luxury/mckinsey-china-luxury-report-2019-how-young-chinese-consumers-are-reshaping-global-luxury.ashx">outside the Chinese mainland</a> .</p> <p>What’s more, most of this overseas shopping is done by women between the ages of 19 and 29, according to a 2018 survey of <a href="http://223.27.21.115/~allegiantmediaco/wp-content/uploads/Documents/CN-Travel-Shopper-White-Paper-Final.pdf">over 750 million Chinese people</a>. From our interviews <a href="https://www.emerald.com/insight/content/doi/10.1108/TR-08-2019-0335/full/html">with many of these women</a>, it seems clear that as the Chinese economy recovers from coronavirus they will return to spending. Where they are able to travel and spend will have a big impact on economic recoveries from the pandemic.</p> <p><strong>The awakened generation</strong></p> <p>In China, demographic cohorts are defined by decades. Rather than millennials or generation Z, in China it is the post-90s generation (those born in the 1990s) that have become the core driver of growth for many industries, including luxury, leisure and travel retail.</p> <p>China’s post-90s generation are the direct beneficiaries of the country’s economic reform that began in the 1980s, which opened up the Chinese market to the rest of the world and spurred enormous economic growth through the 1990s to today. Girls, in particular, benefited from growing up at a time when China was more connected with the rest of the world and experienced significant cultural changes, including a decline in the <a href="https://link.springer.com/article/10.1007/s10834-011-9277-9">historic preference for sons</a>. The one-child policy played a part in this, too.</p> <p>Compared with previous generations, which are more family-centred and self-effacing, post-90s Chinese women are self-confident, independent and well-educated. They are also keen to express themselves through consumerism. This was evident in the conversations we had with high-spending young women. For them, buying luxury goods was a key part of their identity and self-expression. When travelling, it was one of the most important parts of their holiday, if not the actual purpose for their trip.</p> <p>Around the world, people buy and display luxury goods – from fancy cars to expensive watches and handbags – as status symbols. This is especially the case for the post-90s Chinese woman who seeks to distinguish herself from others in various ways. Vivian*, who’s 30, has a master’s degree and works in finance, told us:</p> <p><em>Buying luxury branded products is very personal. It’s my handbag. I do not want to look like everyone else.</em></p> <p>Travelling further afield to Europe is a way to buy luxury goods that distinguish themselves from their peers, as different designs are available to those in China. As well as the premium shopping experience, the people we spoke to repeatedly talked about the importance of having unique items. Ava, a 23-year-old student, said:</p> <p><em>Those special designs somehow are much more beautiful than those basic items that are available everywhere [in China]. They also reflect my lifestyle as a well-travelled person. When I carry it around, people know I am special.</em></p> <p>We also found that for the post-90s Chinese woman who travels abroad, buying designer items in the country where they originated from was seen as part of the authentic experience. As Emma, who is 23 and works in fashion, put it:</p> <p><em>Buying handbags in Paris makes me feel like a French lady. It’s a fun and authentic experience. It is a very different experience to purchasing them in Shenzhen.</em></p> <p><strong>‘Revenge spending’</strong></p> <p>The coronavirus pandemic has not reduced this appetite among China’s wealthy post-90s generation to travel and spend. A survey from <a href="https://blog.globalwebindex.com/chart-of-the-week/coronavirus-reshaping-the-luxury-market/">April this year found</a> that almost 60% of this group who had delayed their purchase plans would return to spending once the outbreak was over in China. And a number of luxury businesses reported a <a href="https://edition.cnn.com/2020/06/11/business/global-luxury-sales-china-coronavirus-intl-hnk/index.html">big rise in spending</a> following the easing of lockdown restrictions in China, including jewellery brand Tiffany and fashion house Burberry.</p> <p>While overseas travel restrictions will significantly reduce the outbound tourist market for the time being, many brands will be hoping for a similar bout of so-called <a href="https://www.cnbc.com/2020/05/13/revenge-spending-by-the-rich-could-drive-luxury-recovery.html">“revenge spending”</a>, as people make up for the time spent cooped up in lockdown.</p> <p>Having been the first to be hit by coronavirus, China is the first major economy to show a recovery. And as the world’s largest (and still growing) source of travellers and luxury shoppers, China will be the engine of the post-pandemic recovery for both these sectors. Both should be aware of what motivates this younger generation to spend in order to tap into it. Growing tension between the west and China, along with struggles to contain the pandemic in the west, may see other Asian countries as the first to benefit from outbound Chinese tourists.</p> <p>*<em>Names have been changed.</em></p> <p><em>Written by Misha Ketchell</em><em>. This article first appeared on <a href="https://theconversation.com/how-the-decline-in-chinese-tourists-around-the-world-has-hit-the-luxury-sector-145267">The Conversation</a>. </em></p>

Man charged with murdering his sister declines court and bail

<p>The father of a Western Sydney artist allegedly killed by her older brother said he never imagined his own son would end up being charged with his daughter’s murder.</p> <p>Lucas Delaney, 30, was arrested on Tuesday morning, less than 24 hours after the body of his sister, Gabriella Delaney, 20, was found inside their shared Cambridge Park townhouse in Western Sydney.</p> <p>On Wednesday, Lucas chose not to appear on screen in Parramatta Court and did not apply for bail. He will remain behind bars until August 7 when his case is mentioned again.</p> <p>The siblings’ parents, who live in Western Australia, called NSW Police after failing to hear from Gabriella since June 3.</p> <p>Officers discovered Gabriella in a “very confronting” crime scene on Monday night, Detective Inspector Jason Pietruszka said.</p> <p>“The cause of death at the moment is being investigated,” he said.</p> <p>“We do believe unfortunately that it is foul play and it is being investigated as a homicide.”</p> <p>Court documents state that Lucas is being charged with the “murder (domestic violence)” of Gabriella on June 3.</p> <p>Lucas had checked into a mental-health facility at Cumberland Hospital in the days after he allegedly murdered his sister.</p> <p>In a Facebook comment, the siblings’ father Ross Delaney said he and his wife Brenda “know as much as the media is telling us ATM … feeling numb and confused really”.</p> <p>Gabriella, an aspiring Indigenous painter, was studying a Bachelor of Design (Visual Communication) at Western Sydney University before she died.</p> <p>A fried, Kyle Plant, paid tribute to the late student in a Facebook post.</p> <p>“I am still trying to piece together how something like this could happen to someone I knew. Someone so kind. Someone so gentle,” Plant wrote.</p> <p>“Gabriella Delaney was an amazing human-being. Hardworking, creative, funny, sporty, so kind hearted and a genuinely great person. We honestly need more people like her in this world not less. Rest In Peace.”</p> <p><em>If you or someone you know is experiencing violence or abuse, you can contact 1800RESPECT on 1800 737 732.</em></p>
