It’s extremely hot and I’m feeling weak and dizzy. Could I have heat stroke?

<p><em><a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Australia is braced for a hot, dry summer. El Nino is back, and this year it will occur alongside an <a href="https://www.abc.net.au/news/2023-08-22/positive-indian-ocean-dipole-to-coincide-with-el-nino/102756378">Indian Ocean dipole</a>, a climate pattern which will further amplify this hot and dry effect.</p> <p>Hot weather can place great stress on our bodies. When the environmental conditions exceed the limit at which we can adequately cope, we can suffer from heat-related illnesses.</p> <p>Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke.</p> <h2>What are the signs and symptoms?</h2> <p>If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness.</p> <p>Mild <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">symptoms of heat exhaustion</a> can often be treated at home by reducing your levels of physical activity, finding shade, removing excess clothing, hydrating with water and perhaps even taking a cool shower.</p> <p>If left unchecked, heat exhaustion can progress to the far more serious condition of heat stroke, where your core temperature climbs upwards of 40°C. <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">Symptoms</a> can develop rapidly and may include confusion, disorientation, agitation, convulsions, or it could even result in a coma.</p> <p>Heat stroke is a medical emergency and requires urgent treatment. Call an ambulance and start rapid, aggressive cooling by immersing the person in cold water (such as a cold bath). If this isn’t possible, apply ice packs to their neck, armpits and groin and cover the skin with lots of cool water.</p> <p>When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second.</p> <h2>Why do we overheat?</h2> <p>Environmental conditions play an important role in determining our heat stress risk. If the air temperature, humidity and levels of sun exposure are high, we are much more likely to dangerously overheat.</p> <p>When the body gets hot, the heart pumps more warm blood to our skin to help lose heat. As air temperature rises, this way of shedding heat becomes ineffective. When air temperature is higher than the temperature of the skin (normally around 35°C), we start gaining heat from our surroundings.</p> <p>Sweating is by far our most effective physiological means of keeping cool. However, it is the <em>evaporation</em> of sweat from our skin that provides cooling relief.</p> <p>When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates.</p> <p>Our physical activity levels and clothing also impact heat stress risk. When we move, our bodies generate metabolic heat as a by-product. The more intense physical activity is, the more heat we must lose to avoid dangerous rises in core temperature.</p> <p>Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool.</p> <h2>Who is most vulnerable in the heat?</h2> <p>Some people <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/people-most-at-risk.aspx">are at greater risk</a> of developing heat illness than others. This can result from physiological limitations, such as a decreased capacity to sweat, or a reduced capacity to adapt our behaviour. When these two risk factors coincide, it’s a perfect storm of vulnerability.</p> <p>Take, for example, an elderly outdoor agricultural worker. Being aged over 60, their physiological capacity to sweat is reduced. The worker may also be wearing heavy safety clothing, which may further limit heat loss from the body. If they don’t slow down, seek shelter and adequately hydrate, they become even more vulnerable.</p> <p>When a person dies of heat stroke – which is relatively easy to diagnose – heat will be listed as a cause of death on a death certificate. Between 2001 and 2018 in Australia, 473 heat-related deaths were <a href="https://www.sciencedirect.com/science/article/pii/S2212420921006324">officially reported</a>.</p> <p>However, the true association between heat and death is thought to be far greater, with an <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(20)30100-5/fulltext">estimated 36,000 deaths</a> in Australia between 2006 and 2017.</p> <p>This is because most people who die during extreme heat events do not die from heat stroke. Instead, they they die of <a href="https://www.nejm.org/doi/full/10.1056/nejm199607113350203">other medical complications</a> such as cardiovascular or renal collapse, as additional strain is placed on essential organs such as the heart and kidneys.</p> <p>People with underlying health conditions are more likely to succumb to heat-associated complications before they develop critical core temperature (over 40°C) and heat stroke.</p> <p>In such cases, while the additional physiological strain imposed by the heat probably “caused” the death, the official “cause of death” is often listed as something else, such as a heart attack. This can make understanding the true health burden of extreme heat more difficult.</p> <h2>How to stay safe in the heat</h2> <p>Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

Daily aspirin doesn’t prevent strokes in older, healthy people after all

<p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The daily use of <a href="https://www.nps.org.au/australian-prescriber/articles/drugs-in-secondary-stroke-prevention">low dose aspirin</a> has been a mainstay of preventing strokes for decades. While there has always been a risk of bleeding associated with aspirin use, the benefits were thought to outweigh the risk.</p> <p>Now <a href="https://dx.doi.org/10.1001/jamanetworkopen.2023.25803">new research</a> led by Monash University has shown daily, low-dose aspirin doesn’t prevent strokes in relatively healthy people aged over 70. And it increases their risk of bleeding on the brain after falls or other injuries.</p> <p>But if you’re taking aspirin, it doesn’t mean you should abruptly stop. It may still have a role to play in treating people at high risk of stroke. Or, after talking to your doctor, there might be better options available.</p> <h2>Why has aspirin been used to prevent strokes?</h2> <p>Aspirin is an anti-platelet medicine, which is commonly known as a blood-thinner. <a href="https://www.lifeblood.com.au/blood/learn-about-blood/platelets">Platelets</a> are the component of blood primarily responsible for its clotting action. They are what stop you from continuously bleeding any time you have a cut or scrape on your skin.</p> <p>A <a href="https://strokefoundation.org.au/about-stroke/learn/what-is-a-stroke">stroke</a> is when oxygen can’t get into the brain because of a burst or blocked blood vessel. A blockage can occur when platelets in the bloodstream form a clot and it gets stuck in the artery.</p> <p>Because aspirin acts on platelets, it can help prevent the clots that can lead to a stroke.</p> <p>But because aspirin acts on platelets, it can also increase the risk of <a href="https://www.mayoclinic.org/diseases-conditions/heart-disease/in-depth/daily-aspirin-therapy/art-20046797#:%7E:text=While%20daily%20aspirin%20can%20help,of%20developing%20a%20stomach%20ulcer.">unwanted bleeding</a>, usually in the stomach. It can also increase your risk of bleeding more when you have another injury, like hitting your head.</p> <p>Aspirin isn’t just used for the prevention of strokes. It is also the first aid treatment for someone undergoing a <a href="https://www.nps.org.au/australian-prescriber/articles/acute-myocardial-infarction-early-treatment">heart attack</a>.</p> <h2>Findings of the Monash trial</h2> <p>New <a href="https://dx.doi.org/10.1001/jamanetworkopen.2023.25803">research from Australia and the United States</a> reports results from the Aspirin in Reducing Events in the Elderly (ASPREE) trial.</p> <p>The researchers examined the protective use of daily low-dose aspirin (100 mg) in nearly 2,000 people who were aged 70 years and older and had no history of heart disease or stroke and whose blood pressure and cholesterol were well managed.</p> <p>When compared with placebo, aspirin didn’t reduce or increase the risk of stroke. Of the participants who took the aspirin, 195 or 4.6% had a stroke. Of those who took the placebo, 203 people or 4.7% had a stroke.</p> <p>But it did statistically increase the rate of non-stroke bleeding in the participants’ brains, for example when they injured their head. Those on aspirin showed a rate of bleeding in the brain of 1.1% (108 participants) compared with 0.8% (79 people) for those on placebo. This is a relatively, low but serious, risk.</p> <p>These findings are not entirely new. <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1800722?query=featured_home">Research</a> published five years ago based on the same ASPREE trial showed a similar result: a higher rate of bleeding among those taking low-dose aspirin compared with placebo.</p> <p>However as the study authors note, aspirin continues to be widely used for the prevention of stroke.</p> <h2>What are the study’s limitations?</h2> <p>The researchers examined aspirin in mostly people of white European heritage.</p> <p>So we don’t know whether the results are translatable to people with different ethnic backgrounds. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2594139/">Genetics and ethnicity</a> can significantly impact the efficacy and safety of some drugs.</p> <p>The clinical trial only included people who were not significantly at risk of a stroke, and had no history of heart disease.</p> <p>Younger age groups were not studied either, so we cannot make any conclusions about their use of low dose aspirin to prevent stroke.</p> <p>It’s also possible the potential benefits and risks are different for those who have underlying heart problems or who have previously had a stroke and are therefore at higher risk of another stroke.</p> <h2>I’m taking aspirin, what should I do?</h2> <p>If you’re taking daily low-dose aspirin and are concerned by the results of the study, it’s important you don’t just stop taking your medicine. Speak to your doctor or pharmacist.</p> <p>For people who are at high risk of having a stroke, or have previously had one, low-dose aspirin may remain their treatment of choice despite the slight bleeding risk.</p> <p>If you’re at high risk of bleeding, for example because of falls and other accidents due to advanced age, frailty, or another underlying condition, your doctor may be able to reduce the amount of aspirin you take by adding in <a href="https://www.nps.org.au/australian-prescriber/articles/dipyridamole">dipyridamole</a> or prescribing a different medicine completely, such as <a href="https://www.nps.org.au/australian-prescriber/articles/clopidogrel">clopidogrel</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210388/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nial-wheate-96839">Nial Wheate</a>, Associate Professor of the Sydney Pharmacy School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/tina-hinton-329706">Tina Hinton</a>, Associate Professor of Pharmacology, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty </em><em>Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

With the strokes of a guitar solo, Joni Mitchell showed us how our female music elders are super punks

<p>The iconic Joni Mitchell’s recent surprise performance at the <a href="https://www.youtube.com/watch?v=jxiluPSmAF8&amp;feature=youtu.be">2022 Newport Folk Festival</a> prompted a world-wide outpouring of love and respect. </p> <p>This was her first musical performance since suffering from a brain aneurysm in 2015 that left her unable to walk and talk. Last year, she spoke of having <a href="https://www.nme.com/en_au/news/music/joni-mitchell-addresses-health-issues-in-rare-speech-at-2021-kennedy-center-honors-3112447">polio as a child</a> as “a rehearsal for the rest of my life”. </p> <p>The tributes for Mitchell celebrated her triumph from illness to recovery, but they also paid homage to Mitchell’s career that has pivoted on protest. </p> <p>Mitchell is largely associated with folk scenes of the 60s and 70s. She has produced a prolific body of work, advocating for social change. As a committed activist she has spoken against environmental degradation, war, LGBTQI+ discrimination, and most recently, removed <a href="https://www.theverge.com/2022/1/29/22907696/joni-mitchell-spotify-joe-rogan-podcast-misinformation-covid-19">her music catalogue</a> from Spotify in a protest against anti-vaccine propaganda. </p> <p>Now, with the <a href="https://www.youtube.com/watch?v=G7wOdpxGctc">strokes of a guitar solo</a> she repositioned herself from folk hero to punk provocateur, defying the “permissible” ways older women “should” behave. </p> <p>In commanding public space and using one of the most traditionally masculinised expressions of popular music practice, she directly challenged the sorts of expectations many people have around gendered norms, particularly what women in their elder years look and sound like.</p> <h2>Not everyone gets to age on stage</h2> <p>Some of the most persistent social restrictions placed on women and gender diverse musicians are in relation to age. </p> <p>Ongoing expectations of older women are to be passive, quiet and very much in the background. They are rarely asked, or expected, to “take up space” in the same ways their male counterparts do. </p> <p>Whereas men step through phases of youthful experimentation into established music legends, there are tiresome obstacles for female and gender diverse people to do the same. </p> <p>And while exceptions are often exceptional, they are not plentiful.</p> <p>It’s not just age. Women have long been sidelined when it comes to acknowledging their skills on the electric guitar. Much like Mitchell.</p> <p>The electric guitar has been an important part of rock and punk genres. There is a symbiotic relationship between how these genres – and the instrumentation that defines them – have unwittingly become gendered. The electric guitar solo in particular has come to be associated with machismo: fast, loud, expert, brave. </p> <p>If you like to imagine a world where women don’t exist, google “best guitar solos ever”. </p> <p>A recent <a href="https://www.nytimes.com/interactive/2022/04/02/opinion/grammys-rock-guitar-solo.html">New York Times article</a> suggested things are starting to change. Citing guitarists like Taja Cheek and Adrianne Lenker, the Times suggested the guitar solo has shifted from a macho institution into a display of vulnerability, a moment (perhaps many) of connectivity. </p> <p>Mitchell’s performance sits somewhere in this domain. </p> <p>For the hundreds of thousands of women and gender diverse guitarists world-wide, myself included, the electric guitar and the genres it is entwined with offer a cool, optional extra: to test the cultural norms of gender with other markers of identity like class, culture, sexuality and age, to blur ideas of what we should and shouldn’t do.</p> <h2>Australian women to the front</h2> <p>Australian women and gender diverse rock and punk musicians are often subject to a double act of erasure – missing from localised histories, and also from broader canons of contemporary music, which often remain persistently rooted in the traditions of the UK and the US.</p> <p><a href="https://www.goodreads.com/en/book/show/55669013-my-rock-n-roll-friend">Tracey Thorn’s brilliant biography</a> of the Go-Between’s drummer Lindy Morrison is a love lettered homage that steps out the complex local, emotional, personal and structural ways that Australian women and gender diverse people are often omitted from cultural spaces. </p> <p>“We are patronised and then we vanish,” writes Thorn.</p> <p>The work of women and gender diverse artists is often compared to the glossy pedestal of the male creative genius.</p> <p>In this light, we don’t play right, we don’t look right, we don’t sound right. </p> <p>And then, somehow, we don’t age right. </p> <p>Other reasons are far more mundane. Women contribute around <a href="https://www2.deloitte.com/au/en/blog/economics-blog/2019/Value-unpaid-work-care.html">13 hours more unpaid work</a> than men each week. </p> <p>Carrying plates overflowing with generous gifts of labour, the maintenance of a music practice – a largely underpaid endeavour – is often the first to fall by the wayside. </p> <p>Add to the mix ingrained social networks of knowledge sharing, and the dominance of men making decisions higher up the chain, and it is easy to see how women and gender diverse musicians stay submerged as men rise to the limited real estate of music elders. </p> <p>The problem isn’t so much about starting up. It’s about finding the time to keep up.</p> <h2>Our female and gender diverse music elders</h2> <p>There are so many Australian female and gender diverse music elders. Some are visible, but many ripple beneath the surface. </p> <p>Regardless of genre, in maintaining decades-long practice, they are the super punks whose legacy can be heard in venues across the country. </p> <p>The challenge now is to support the current crop of excellent musicians beyond the flushes of youth so that we have a more sustainable, textured and diverse Australian music culture. One where Mitchell’s defiance of expectations represents the status quo of how older women should and can be.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/with-the-strokes-of-a-guitar-solo-joni-mitchell-showed-us-how-our-female-music-elders-are-super-punks-188075" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Australian women are less likely to receive pre-hospital stroke care than men

<p>Paramedics are failing to recognise strokes in women as much as they do for men, according to a new <a href="https://newsroom.unsw.edu.au/news/health/women-less-likely-receive-pre-hospital-stroke-care-men" target="_blank" rel="noreferrer noopener">study</a> of New South Wales stroke patients. Researchers suggest that clinician sex bias might be the cause.</p> <p>In 2018 it was <a href="https://www.aihw.gov.au/reports/heart-stroke-vascular-diseases/hsvd-facts/contents/heart-stroke-and-vascular-disease-and-subtypes/stroke" target="_blank" rel="noreferrer noopener">estimated</a> that 387,000 Australians aged over 15 years had experienced a stroke at some point in their lives. The success of treatment is very time dependent, so it’s critical that patients suffering from stroke are identified as soon as possible, preferably before arriving at hospital.</p> <p>But according to the study by Australian researchers, women (aged under 70) suffering with stroke were less likely than men to receive stroke care management prior to hospital admission – despite being more likely to arrive at hospital by ambulance.</p> <p>This is concerning, as other research shows stroke outcomes are <a href="https://pubmed.ncbi.nlm.nih.gov/31719135/" target="_blank" rel="noreferrer noopener">generally worse</a> for women than men – with greater stroke-related disability and poorer subsequent quality of life.</p> <p>“Our study suggests that better recognition of stroke symptoms in women by ambulance staff could ensure the right treatment is started as early as possible and give them the best opportunity for recovery,” says lead author Dr Xia Wang, research fellow at The George Institute for Global Health in Sydney.</p> <p>There are two types of stroke: ischaemic stroke occurs when a vessel supplying blood to the brain becomes blocked, and haemorrhagic stroke occurs when one ruptures and begins to bleed. This can cause parts of the brain to die – resulting in impairment that can affect things like speech, movement, and communication – or can often be fatal.</p> <p>Thanks to development in medical research <a href="https://www.nhs.uk/conditions/stroke/treatment/" target="_blank" rel="noreferrer noopener">treatment for stroke</a> is changing, but the efficacy of these treatments is highly time-dependent and rapid and accurate pre-hospital assessment is critical for successful outcomes.</p> <p>“When stroke is not recognised early, delays can have serious consequences,” says co-author Dr Cheryl Carcel, senior research fellow and academic lead of the George Institute’s Global Brain Health Initiative.</p> <p>“Procedures for in-ambulance stroke care ensure patients with stroke symptoms are brought to a high-level specialised facility quickly to receive life-saving treatment.”</p> <p>In a population-based cohort study, researchers analysed data from more than  200,0000 patients (51% women) admitted to NSW hospitals between July 2005 and December 2018 and subsequently diagnosed as having a stroke.</p> <p>Just over half of all stroke patients were taken to hospital via ambulance, with women (52.4%) more likely than men (47.9%) to arrive this way.</p> <p>Despite this, women were less likely to receive stroke care management prior to hospital admission.</p> <p>“Among patients under 70 years of age, women were less likely than men to be assessed by paramedics as having a stroke, but there was no significant difference for older patients,” the authors say.</p> <p>Instead, they were more frequently assessed by paramedics as having conditions which mimic stroke – like headache or migraine, anxiety, and unconsciousness – which contributed to a delay in the recognition and treatment of stroke.</p> <p>There was no significant difference for older patients.</p> <p>Health professionals know that on initial presentation, <a href="https://pubmed.ncbi.nlm.nih.gov/31114842/" target="_blank" rel="noreferrer noopener">atypical clinical symptoms of stroke</a> occur more frequently in women. So, these findings could be due to a difference in symptoms, although it’s also possible that implicit sex bias exists amongst healthcare providers.</p> <p>“While there aren’t any studies looking at clinician sex bias in stroke, we have evidence from other countries where it is happening in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3810172/" target="_blank" rel="noreferrer noopener">coronary artery disease</a>,” explains Carcel.</p> <p>This has also been <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002870321001885?via%3Dihub" target="_blank" rel="noreferrer noopener">found</a> to be the case for myocardial infarction (heart attack), with women less likely to be assessed by paramedics as having MI than men.</p> <p>“Greater awareness among all health professionals about differences in symptom presentation between men and women could help address this bias,” concludes Carcel. “In the case of stroke, this is particularly important for ambulance staff, so that women are identified early and treatment is commenced even before they reach the hospital.”</p> <p>This article originally appeared on <a href="https://cosmosmagazine.com/people/australian-women-stroke-care/" target="_blank" rel="noopener">Cosmos</a>. </p> <p><em>Image: Getty</em></p>

Stroke, cancer and other chronic diseases more likely for those with poor mental health

<p><a href="https://www.aihw.gov.au/reports-statistics/health-welfare-services/mental-health-services/overview">Four million Australians</a>, including our friends, family members, co-workers and neighbours, are living with mental health conditions, including anxiety and depression.</p> <p>A <a href="https://www.vu.edu.au/australian-health-policy-collaboration/publications#chronic-diseases">new report out today</a> from the <a href="https://www.vu.edu.au/australian-health-policy-collaboration">Australian Health Policy Collaboration</a> has found these four million Australians are at much greater risk of chronic physical disease and much greater risk of early death.</p> <p>Having a mental health condition increases the risk of every major chronic disease. Heart disease, high blood pressure, arthritis, back pain, diabetes, asthma, bronchitis, emphysema and cancer are all much more likely to occur among people with anxiety and depression. </p> <p>More than 2.4 million people have both a mental and at least one physical health condition.</p> <p>For the first time in Australia, this report quantifies the extent of this problem. For example, people with mental health conditions are more likely to have a circulatory system disease (that is, heart disease, high blood pressure and stroke). The likelihood increases by 52% for men, and 41% for women.</p> <p>More than a million people are affected by both a circulatory system disease and a mental health condition. These diseases are Australia’s biggest killers.</p> <p>For painful, debilitating conditions such as arthritis and back pain, the numbers are even higher. Arthritis is 66% more likely for men with mental health conditions, and 46% more likely for women, with 959,000 people affected.</p> <p>Back pain is 74% more likely for men with mental health conditions, and 68% more likely for women, with more than a million affected.</p> <p>The gender differences are significant. Women with mental health conditions are much more likely to have asthma than women across Australia as a whole (70% more likely), while men are 49% more likely to have asthma with a mental health condition.</p> <p>The biggest gender difference is cancer. Men with mental health conditions are 84% more likely to have cancer than the general population, and for women the figure is 20%.</p> <p>As more women live with mental health conditions than men, overall, women are 23% more likely to be living with both a mental and physical health condition than men.</p> <p>The report shows having a co-existing mental health condition and chronic physical disease generally results in worse quality of life, greater functional decline, needing to use more health care and higher healthcare costs. </p> <p>These people require more treatment, use more medications, and have to spend more time, energy and money managing their health. People with a mental health condition are also <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60240-2/abstract">more likely to be poorer</a>, less likely to work, less likely to receive health screening and, sadly, <a href="https://www.rethink.org/media/810988/Rethink%20Mental%20Illness%20-%20Lethal%20Discrimination.pdf">more likely to receive substandard care</a> for their physical diseases.</p> <p>On average, people with mental health conditions die younger than the general population, and mostly from preventable conditions. We know from <a href="https://www.bmj.com/content/346/bmj.f2539">earlier research</a>that people with severe mental illnesses die much earlier than the rest of the population. Our report shows even common mental health conditions such as anxiety and depression contribute to more chronic disease, leading to higher rates of early death.</p> <h2>Why?</h2> <p>We don’t know exactly why people with mental health conditions have poorer physical health. The <a href="https://acmedsci.ac.uk/policy/policy-projects/multimorbidity">Academy of Medical Sciences</a> has identified that poor mental health and psychosocial risk factors such as feeling dissatisfied with life, not feeling calm, having sleep problems that affect work, and financial concerns can predict physical disease.</p> <p>Other factors, such as <a href="https://theconversation.com/low-income-earners-are-more-likely-to-die-early-from-preventable-diseases-87676">low socioeconomic status</a>, poor social networks, living in rural areas and smoking are associated with both poor mental health and poor physical health.</p> <p>We do know people with mental health conditions often don’t receive advice about healthy lifestyles, don’t get common tests for disease, and are less likely to receive treatment for disease. Some of this is due to <a href="https://www.ncbi.nlm.nih.gov/pubmed/21379357">stigma and discrimination</a>, and sometimes it’s neglect. People with mental health conditions can <a href="https://www.ranzcp.org/Files/Publications/RANZCP-Serious-Mental-Illness.aspx">fall through the gaps between disjointed physical and mental health systems</a>. </p> <h2>What can we do about it?</h2> <p>There is <a href="https://www.ranzcp.org/Files/Publications/RANZCP-Keeping-body-and-mind-together.aspx">momentum for change</a> among the mental health sector, with dozens of organisations signing up to the <a href="https://equallywell.org.au/">Equally Well</a> consensus statement. This aims to improve the quality of life of people living with mental illness by providing equal access to quality health care. </p> <p>There’s some great work being done around the country, including in the <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/inm.12459">Hunter region</a>, where people with mental health conditions can access tailored help with physical health risk factors such as smoking and diet.</p> <p>People using mental health services should have their physical health regularly assessed, and any problems addressed as early as possible. Better coordination of care would preserve healthcare resources and improve quality of life.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/stroke-cancer-and-other-chronic-diseases-more-likely-for-those-with-poor-mental-health-100955" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Best stroke: Microswimmers that can deliver drugs around the body

<p>Picture an artificial cell: a self-propelling mixture of chemicals, somewhere between a thousandth and a tenth of a millimetre in size, able to travel around the body delivering medicines.</p> <p>This could become a reality with microswimmers – micrometre-sized blobs of liquid that can move independently, thanks to either chemical or physical mechanisms. There are plenty of naturally occurring microswimmers, but researchers have begun to tune artificial ones to do more interesting jobs.</p> <p>Artificial microswimmers can be very simple – last year, a group of researchers published a method for microswimmers you could <a href="https://cosmosmagazine.com/science/almost-home-made-microswimmers/" target="_blank" rel="noreferrer noopener">make at home</a> (provided you have a pipette and a microscope). But more complex “microrobots” have even more potential.</p> <p>Last month, for instance, researchers at the Max Planck Institute for Intelligent Systems, Germany, announced they’d developed light-powered microswimmers that can move through biological fluids.</p> <p>The researchers’ microswimmers are made from a porous substance called poly(heptazine imide) carbon nitride. This material comprises organic (carbon-containing) molecules linked together in a flat sheet, making it a “two-dimensional” <a href="https://cosmosmagazine.com/science/explainer-what-is-a-polymer/" target="_blank" rel="noreferrer noopener">polymer</a>.</p> <p>The microswimmers can be propelled forwards by light, and can also be triggered to release chemicals they’re holding – making them prime targets for drug delivery.</p> <p>Light-powered microswimmers aren’t an entirely new concept, though it had previously been tricky to make them work in biological environments.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p182933-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.56 resetting spai-bg-prepared" action="/technology/materials/microswimmers-targeted-drug-delivery-light/#wpcf7-f6-p182933-o1" method="post" novalidate="novalidate" data-status="resetting"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page spai-bg-prepared" name="referer-page" type="hidden" value="https://cosmosmagazine.com/health/" data-value="https://cosmosmagazine.com/health/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>“The use of light as the energy source of propulsion is very convenient when doing experiments in a petri dish or for applications directly under the skin,” says co-author Filip Podjaski.</p> <p>“There is just one problem: even tiny concentrations of salts prohibit light-controlled motion. Salts are found in all biological liquids – in blood, cellular fluids, digestive fluids etc.”</p> <p>But these microswimmers can move in even the most saline liquids. Podjaski says this is because of the porous nature of the material, as well as its light sensitivity.</p> <p>“In addition, in this material, light favours the mobility of ions, making the particle even faster,” he says.</p> <p>Currently, the microswimmers can release drugs in very acidic environments, but the researchers are still looking for other release mechanisms they can use. Artificial microswimmers are a long way from drug delivery or use in humans, but they’ve got plenty of exciting potential.</p> <p>“We hope to inspire many smart minds to find even better ways for controlling microrobots and designing a responsive function to the benefit of our society,” says co-author Metin Sitti.</p> <p>The findings were <a href="https://dx.doi.org/10.1126/scirobotics.abm1421" target="_blank" rel="noreferrer noopener">published</a> in <em>Science Robotics.</em></p> <p><!-- Start of tracking content syndication.

Salt substitute leads to fewer strokes and heart attacks

<div class="copy"> <p>A reduced-sodium, potassium-rich ‘salt substitute’ reduces rates of stroke, heart attack and death, according to a new <a rel="noreferrer noopener" href="https://doi.org/10.1056/NEJMoa2105675" target="_blank">study</a> published in <em>The New England Journal of Medicine. </em></p> <p>Researchers from the George Institute for Global Health showed that a salt substitute with more potassium chloride and less sodium chloride – the ‘normal’ table salt – leads to lower blood pressure and reduced heart problems, with no harmful effects.</p> <p>“Almost everyone in the world eats more salt than they should,’’ says lead author Bruce Neal. “Switching to a salt substitute is something that everyone could do if salt substitutes were on the supermarket shelves.</p> <p>“Better still, while salt substitutes are a bit more expensive than regular salt, they’re still very low-cost – just a few dollars a year to make the switch.</p> <p>“As well as showing clear benefits for important health outcomes, our study also allays concerns about possible risks.  We saw no indication of any harm from the added potassium in the salt substitute. Certainly, patients with serious kidney disease should not use salt substitutes, but they need to keep away from regular salt as well.”</p> <p>The study was conducted with 21,000 adults with a history of stroke or blood-pressure issues from 600 rural Chinese villages in 2014/15. For those using the low-sodium salt, the team found that incidents of stroke dropped by 14%, total cardiovascular events (including heart attack) dropped by 13% and premature deaths dropped by 12%.</p> <p>They also showed that the price difference between table salt and the substitute was low – $1.48 per kilogram for regular salt compared to $2.22 per kilogram for low-sodium salt.</p> <p>‘’Last year, a modelling study done for China suggested that about 400,000 premature deaths might be prevented each year by national uptake of salt substitute,” says Neal. “Our results now confirm this. If salt was switched for salt substitute worldwide, there would be several million premature deaths prevented every year.  </p> <p>“This is quite simply the single-most worthwhile piece of research I’ve ever been involved with.  Switching table salt to salt substitute is a highly feasible and low-cost opportunity to have a massive global health benefit.”</p> <p>Because of this result, the researchers have urged salt manufactures to switch to low-sodium salt, and for governments to make policies that promote salt substitutes.</p> <em>Image credits: Shutterstock           <!-- Start of tracking content syndication.

Losing speech after a stroke can negatively affect mental health – but therapy can provide hope

<p>Around <a href="https://www.nejm.org/doi/10.1056/NEJMoa1804492">25% of adults</a> will have a stroke in their lifetime. And <a href="https://www.archives-pmr.org/article/S0003-9993(16)30041-7/fulltext">around one-third</a> of stroke survivors will be left with damage to the part of their brain that decodes and organises language – leaving them with a disability known as <a href="https://www.tandfonline.com/doi/abs/10.1080/02687038.2020.1852003">aphasia</a>. Aphasia can affect speaking and understanding as well as reading and writing abilities, but does not affect intelligence. It can vary in severity from getting a few words mixed up, to being unable to say any words.</p> <p>Aphasia can be a difficult and frustrating disability to live with, and can disrupt many aspects of a person’s life – including relationships, holding down a job, and social activities. As such, depression is common, affecting an <a href="https://www.karger.com/Article/Abstract/16107">estimated two-thirds</a> of people with aphasia. Yet many people with aphasia <a href="https://www.tandfonline.com/doi/abs/10.1080/02687038.2019.1673304">struggle to access</a> the psychological support they need – psychological therapies, or “talk therapies”, can feel inaccessible to someone with a language disability.</p> <p><a href="https://journals.sagepub.com/doi/10.1177/10497323211020290">Our research</a> explored how psychological therapy could be made to work for people with aphasia. Working with speech and language therapists, mental health professionals and stroke survivors, we adapted a form of psychological therapy so that it was accessible for people with aphasia. We found that this form of therapy was valued by people with aphasia, and could make a positive difference in their lives.</p> <p><strong>Accessible therapy</strong></p> <p>The therapy that we delivered to our research participants was adapted from a form of psychological therapy called “<a href="https://www.taylorfrancis.com/books/mono/10.4324/9780203116562/solution-focused-brief-therapy-harvey-ratner-evan-george-chris-iveson">solution-focused brief therapy</a>”. This form of therapy supports a person in building meaningful change in their everyday lives. It invites people to describe their hopes for the future, and explores their skills, talents and resources to support them in when adapting to their new circumstances. It also gives them a chance to discuss their experiences and thoughts.</p> <p>Thirty people with post-stroke aphasia received the therapy in our study. Fourteen of our participants had severe aphasia, while 16 had milder aphasia. They were all at least six months post-stroke – and some were as many as 12 years post-stroke. Participants were offered up to six therapy sessions, each of about an hour, spaced over three months. The therapy was delivered by speech and language therapists who had received specific training and supervision from experts in solution-focused brief therapy.</p> <p>To make the therapy accessible, we made sure that the therapists worked closely with participants to help them communicate their thoughts and feelings, using whatever method they could – so as well as talking, participants communicated through drawing, gestures, pictures, objects, mime, or writing key words. Although their intelligence was not affected, many participants found it harder to understand language when spoken rapidly.</p> <p>To support participants’ understanding, therapists used simpler language, slowed their pace of speech and supported communication visually such as by writing key words, or using gestures or pictures. Above all, the therapists gave people time – time to express their thoughts and time to process what the therapist was saying.</p> <p><img src="https://images.theconversation.com/files/406699/original/file-20210616-3629-1d6qq4s.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="A young man reads a book with an elderly woman." /> <span class="caption">Participants communicated using whatever method they could.</span> <span class="attribution"><a href="https://www.shutterstock.com/image-photo/young-male-nurse-spending-time-elder-300626726" class="source">Photographee.eu/ Shutterstock</a></span></p> <p>Therapists encouraged participants to describe what “living well” with their aphasia meant to them. They invited participants to notice small signs of progress and share their successes and achievements with the therapist. These could be seemingly small events, such as making porridge with one hand for the first time, and also profound conversations around how they experienced aphasia, their early times in hospital, or describing the process of recovery and adjusting to their stroke. The therapists invited them to notice their own skills and the resources that they had drawn on, and how they could use these to help them continue to adjust to their new circumstances.</p> <p>Our participants agreed that the therapy worked well for people with aphasia – and that it was important for them (and others with aphasia) to have access to psychological support if needed. Many valued being able to talk about their hopes and achievements, and share how they found living with stroke and aphasia. They also valued the companionship and connection they felt with their therapist.</p> <p>Many participants also described experiencing positive changes in their life after attending therapy – including having the confidence to start using the phone again, doing things they used to do such as cooking dinner, or starting a volunteer role. For some, it gave them courage, and let them feel more like themselves again.</p> <p>Our research shows that even people with a severe language disability can benefit from this therapy when it is adapted specifically for them. A challenge is ensuring that mental health professionals and speech and language therapists have the training, skills and confidence to provide appropriate psychological support for people with aphasia.</p> <p>There are around <a href="https://www.stroke.org.uk/what-is-aphasia/aphasia-and-its-effects">350,000 people</a> living with aphasia in the UK. Yet <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1460-6984.12204">public awareness</a> of the condition remains low, making it a poorly understood and often lonely disability to live with. If we give people with aphasia the time to express themselves – noticing and valuing them as people, and not just seeing their disability – it can make a real difference in improving their lives.<!-- End of code.

How to survive a stroke

<p><span>When a stroke happens, acting fast is crucial to survival. As the second most common cause of death in New Zealand, stroke interrupts blood supply to the brain, preventing brain cells from accessing oxygen and nutrients and damaging the brain tissue in the process. </span></p> <p><span>According to <a href="https://www.rush.edu/health-wellness/discover-health/surviving-stroke">Rush University Medical Center</a>, 1.9 million brain cells die every minute a stroke goes untreated, increasing the risk of brain damage, disability and death. </span></p> <p><span>The sooner a person receives treatment for stroke, the better the outcome. However, a lack of awareness of early stroke symptoms means that more people may miss out on getting prompt medical attention.</span></p> <p><strong><span>How to recognise the signs of stroke</span></strong></p> <p><span>Not all strokes are sudden and incapacitating – the signs can be subtler than commonly expected. The Stroke Foundation recommends using the FAST test to recognise the main symptoms of stroke:</span></p> <ul> <li>Face: Has their face drooped?</li> <li>Arms: Can they lift both arms? Does one arm drift downward?</li> <li>Speech: Is their speech slurred, and do they understand you?</li> <li>Time: Time is critical. Call the ambulance as soon as you see any of these signs.</li> </ul> <p><span>Other signs of stroke may include:</span></p> <ul> <li>Weakness and/or numbness of the face, arm or leg, especially on one side of the body</li> <li>Blurred or loss of vision in one or both eyes</li> <li>Sudden dizziness, loss of balance or coordination</li> </ul> <p><strong><span>What to do</span></strong></p> <p><span>Should you notice any symptoms on yourself or others, call 111 immediately. </span></p> <p><span>Avoid driving yourself to the hospital – while this may seem like a quicker option, lifesaving treatment begins in the ambulance. Paramedics and ambulance workers can screen you on the way and ensure you get the necessary drugs and the most suitable procedures at the emergency department.</span></p> <p><strong><span>Who is at risk?</span></strong></p> <p><span>According to the <a href="https://brainfoundation.org.au/disorders/stroke/#strokeaffectaustralians">Brain Foundation</a>, the risk of stroke may increase for:</span></p> <ul> <li>People with a family history of stroke</li> <li>People with risk factors such as high blood pressure, high cholesterol, diabetes or obesity</li> <li>Smokers and heavy alcohol drinkers</li> <li>People aged 45 and above</li> </ul> <p><span>Stroke <a href="https://www.healthdirect.gov.au/stroke-prevention">can be prevented</a> with a low-fat, high-fibre diet, regular exercise and avoidance of smoking and excessive alcohol consumption.</span></p>

This can be due to the blood flow being blocked by a clot (ischemic stroke) or when the vessels in the brain burst (haemorrhagic stroke).</span></p> <p>Other incidents are classified as “brain attacks”, which happen when people suffer from a transient ischemic attack (TIA) or otherwise known as “mini strokes”.</p> <p>These occur when there is a blockage of blood flow to the brain.

People who excessively smoke or consume alcohol, live sedentary lifestyles, have high cholesterol, blood pressure or diabetes have a much higher risk of suffering from a stroke. </p>

“Diet” drinks linked to increased risk of dementia and stroke

<p>We all know that too much sugar in our diet is bad for our health, and that includes sugary soft drinks. But many reach for the artificially sweetened ‘diet’ drinks, thinking that it has to be a better choice than sugary soft drinks.</p> <p>It has now been proven that these ‘diet’ drinks are equally bad for our health, if not worse. This is the latest data from the Framingham Heart study in Massachusetts.</p> <p>“We advise that people don’t drink sugary beverages because we know they are associated with a whole range of adverse health outcomes such as obesity, diabetes,” said Matthew Pase, a visiting postdoctoral fellow at Boston University School of Medicine and an investigator at the Framingham Heart Study. Pase, who authored the study, said the outcomes of consuming diet drinks with artificial sweeteners can be just as bad.</p> <p>“We found that those people who were consuming diet soda on a daily basis were three times as likely to develop both stroke and dementia within the next 10 years as compared to those who did not drink diet soda,” said Pase. About 4,000 Framingham residents aged 30 or older were monitored for this study.</p> <p>It was found that those who drank sugary drinks showed faster brain ageing and poorer memory function. <span><a href="http://stroke.ahajournals.org/content/48/5/1139">The conclusion to this study</a></span> was that "artificially sweetened soft drink consumption was associated with a high risk of stroke and dementia." The artificial sweeteners used in the study were saccharin, acesulfame, aspartame, neotame, and sucralose.</p> <p>Aspartame is considered by some to be the most dangerous substance on the market that is added to foods and drinks. It accounts for more than 75 per cent of the adverse reactions reported to the US FDA, yet the additive is still widely permitted and no warning labelling is required.</p> <p>The range of symptoms and ailments attributed to aspartame in a 1994 Department of Health &amp; Human Services Report  include headaches, migraines, memory loss, dizziness, seizures, numbness, rashes, depression, fatigue, irritability, tachycardia, insomnia, vision problems, hearing loss, heart palpitations, breathing difficulties, slurred speech, tinnitus, vertigo and joint pain.</p> <p>Aspartame is an excitotoxin, and excessive exposure can cause damage to your brain cells. It is important to be aware when food shopping that you look at the ingredients list on the packaged foods and drinks. Look out for (950) or (951) - these are the number codes for aspartame, so avoid purchasing anything with those numbers.</p> <p>Start cutting back on the artificially sweetened drinks, with a view of eliminating them completely from your diet to protect your heart and brain health.</p> <p><em><a href="https://www.smartbrainhealthcentre.com.au/">Louise Hallinan</a> is the international award-winning author of </em>Smart Brain, Healthy Brain<em>, a natural medicine practitioner and founder of the Smart Brain Health Centre which specialises in the prevention of memory problems and improving brain health.</em></p>

Having a stroke was the wake-up call I needed to change my life

<p>As John Hughes stood outside his house in Potts Point, Sydney, his knees buckled, his face drooped, and he felt as though he was suddenly drunk.</p> <p>Alarmed and aware something was incredibly wrong he called a taxi to take him to the hospital where he was diagnosed as having a stroke.</p> <p>It was a turning point that would transform his life and help him to drop 18 kilos. Now John is talking out about his incredible journey in an attempt to get others to get active before it’s too late.</p> <p align="center"><img width="498" height="709" src="https://oversixtydev.blob.core.windows.net/media/7818943/johnhughesbefore-2-_498x709.jpg" alt="Johnhughesbefore (2)"/></p> <p align="center"><em>John Hughes before his stroke.</em></p> <p>John was the Associate Dean of Education at Sydney University before retiring in 2009 and admits he had a poor diet, never exercised and despite once previously joining a gym – had never used the membership. His weight spiralled to 94kg.</p> <p>“I ate out a lot and lived off steak and chips or pasta,” says John, 69.</p> <p>“The most exercise I ever got was when I got out of the taxi and had to walk to the Opera House. Even then, I struggled to do it.”</p> <p>John had been diagnosed with Type 2 diabetes and always battled with depression which spiralled when he retired and felt unneeded.</p> <p>“Looking back the stroke was probably the best thing that could have happened to me, but it didn’t feel like that at the time,” he says.</p> <p>“I was left paralysed on my entire left hand side and it took me three weeks before I could even shuffle my feet back and forth. It was six weeks before I could use cutlery again.”</p> <p>John left hospital and continued with regular physiotherapy. It was there they suggested he join the Uniting Senior’s gym, at Waverley.</p> <p align="center"><img width="499" height="665" src="https://oversixtydev.blob.core.windows.net/media/7818947/john-hughes1_499x665.jpg" alt="John Hughes1 (5)"/></p> <p align="center"><em>John started exercising after his stroke.</em></p> <p>Hesitant, John arranged to meet an exercise physiologist at the gym in October 2016. He hasn’t looked back since.</p> <p>“They were so caring, so understanding of my situation. I felt like I truly mattered,” he explains.</p> <p>“They drew up a specific plan for me and we focused a lot on balancing and managing to walk without a stick. It was unlike any gym I’d heard about before.”</p> <p>John worked on targeted stretching, balancing exercises, riding an exercise bike and upper body work. The weight started falling off and John’s confidence grew.</p> <p>“I felt like I was part of a community again and it gave me somewhere to go each day. The confidence was amazing and it truly tackled my depression. Along with visits to a diabetes clinic and a change of my diet, I was transforming myself from the outside in.”</p> <p class="CutThroughCreativeParagaph">Today John weighs 75.5kg and eats his green vegetables regularly. He’s thankful to the team at Uniting who have helped him get his life on track and urges others in similar situations to do the same before it is too late.</p> <p>“Just give it a go, and make sure you find someone who is specialised in senior’s health. No retired person wants someone in their 20s looking at them strangely when they say they haven’t been active for longer than they’ve been alive.”</p>

This exercise could help you walk again after a stroke

<p>Recovering from a stroke can be a painful, difficulty and lengthy process consisting of weeks, months and even years of intense physical therapy.</p> <p>But <a href="http://www.physiology.org/doi/10.1152/jn.00570.2017" target="_blank"><strong><span style="text-decoration: underline;">a new study</span></strong></a>  has found that focusing on arm exercises as well as leg training can help stroke sufferers relearn how to walk faster than leg exercises alone.</p> <p>Researchers from the University of Victoria in Canada studied 19 patients between the ages of 57 and 87 who had suffered a stroke between seven and 17 years prior. They discovered that those who completed 30 minutes of moderate-intensity rhythmic arm cycling, three times a week, performed far better on walking tests after five weeks of training.</p> <p style="text-align: center;"><iframe width="560" height="315" src="https://www.youtube.com/embed/wSOL05XmkTs" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen=""></iframe></p> <p>The walking tests included measuring how far the participants could walk in six minutes, how fast they could walk 10 metres, and how long it took them to stand from sitting, walk 10 feet then return to their seat. All who completed rhythmic arm cycling exercises experienced an improvement in these tests – as much as 28 per cent in the final test.</p> <p>“Arm cycling training activated interlimb networks that contribute to the coordination of rhythmic walking,” researchers wrote. In other words, activating the nerves in the arms helped them improve function of the spinal cord in other parts of the body affected by stroke, including the legs.</p> <p>But it’s not only those who’ve only recently suffered a stroke that can benefit from these exercises – they can help years after injury.</p> <p>“Although improvements in walking may not be as robust as those from other training modalities, they do highlight the integral role that training the arms can have on rehabilitation of human locomotion,” researchers concluded.</p> <p>Tell us in the comments below, have you ever suffered a stroke?

How to help a loved one after a stroke

<p>Before you can effectively help your loved one after they have suffered a stroke, you need to take a little time to understand what a stroke is and how it can affect the body and mind. No two strokes are alike, and depending on the severity as well as the size and length of time one lasts, they can affect people differently. This means that the recovery time needed to heal will be different from one person to another.</p> <p>The first couple of weeks after a person has a stroke are critical for determining the amount of damage done by the stroke. It can be a time of confusion for you, but even more so for the patient who has had the stroke. Life can suddenly feel turned completely upside down, and support will be greatly needed by the stroke survivor.</p> <p><strong>What happens during a stroke?</strong></p> <p>First, to help your loved one, you need to be educated on what happens during a stroke. During a stroke, a blood vessel that carries blood to <a href="http://www.oversixty.com.au/health/mind/2018/01/how-to-improve-brain-flexibility/" target="_blank"><strong><span style="text-decoration: underline;">the brain</span></strong></a> either bursts or becomes blocked. This means that the brain is not getting the oxygen that it needs to have and within minutes, brain cells begin to die. There are two kinds of strokes;</p> <ol> <li>Ischemic stroke – An ischemic stroke affects the largest number of stroke patients and it happens when a blood vessel is blocked by fatty deposits. You can also have a thrombotic ischemic stroke which means a blood clot has formed where the vessel is blocked.</li> <li>Hemorrhagic stroke – A hemorrhagic stroke happens when a weakened blood vessel collapses and causes a bleed into the brain. This can be caused by an aneurism or other issues.</li> </ol> <p><strong>Stroke symptoms</strong></p> <p>Knowing how to identify the symptoms of a stroke can be a great way to get help quick and cut down on the chance of long-term effects. Many doctors recommend using the <a href="http://www.oversixty.com.au/health/caring/2016/06/understanding-the-symptoms-of-stroke/" target="_blank"><strong><span style="text-decoration: underline;">F.A.S.T. acronym</span></strong></a> for strokes to identify the symptoms.

This is important for stroke patients as well as everyone else as quality medical care is a vital part of a healthy life.</p> <p>Once your loved one has received medical treatment and their doctor deems them healthy enough to return home to continue recovery, it is vital to their healing that they have a support system in place to help them as they heal. Here are some things you can do to help your loved one recover.</p> <ul> <li>Clean the house and clear a path so they can easily navigate rooms without tripping over anything.</li> <li>If their bedroom is upstairs, try making a bed up downstairs where they won’t have to climb stairs, or be assisted going up and down steps to get to or from the bedroom.</li> <li>Have a bedpan for use so they can get to it fast if necessary.</li> <li>Talk to their doctor before they are released to see if they need a walker, wheelchair or other assistance with moving around.</li> <li>Add bed rails to the bed so they won’t slip out and fall.</li> <li>If your loved one has a feeding tube (which is extremely normal after a stroke) you need to learn to insert it (even if they have a nurse) and check it to make sure it is working correctly and not causing discomfort or coming loose.</li> <li>Strokes can, and often do, cause <a href="http://www.oversixty.com.au/health/hearing/2017/09/6-things-you-should-not-do-when-talking-to-a-person-with-hearing-loss/" target="_blank"><strong><span style="text-decoration: underline;">hearing loss</span></strong></a> as well as speech impediments. It will take time for the stroke victim to relearn speech and it is very important to show them patience and help them as they relearn how to voice their words. Try to use small hand gestures to show them things. You may even want to try to use vision boards or let them try to write things down if they are able to write.</li> <li>Many people suffer from bladder problems and will need to wear an adult diaper for a while after a stroke. Be kind about this and help with changing and cleaning to avoid infections and sores.</li> <li>One of the biggest concerns after a stroke is the anger or depression that a stroke patient may have because of what the stroke has damaged. This is common, and most stroke patients will experience some degree of both. As a loved one, show them you care and if you notice any major emotional problems, contact their physician to let them know so they can prescribe the proper medication or therapy to help.</li> </ul> <p>You also need to help your loved one by making sure they can get to the doctor or therapy appointments when they are scheduled. If they need to do exercise therapy at home to regain movement, it’s a big help if you can work alongside them to make them feel more comfortable with healing. Keep in mind that just as no two strokes are the same, the healing time varies from one person to another. It may be a long road to recovery, but with patience and love from you, you can help your loved one as they recover and work towards a stable life again.</p> <p><em>Written by Jason Mueller.</em></p>

The number one nutrient you need to prevent stroke

<p>When it comes to preventing stroke, we’re usually told our best bet is to control our blood pressure, avoid smoking, eat healthy and be active. But in addition to this advice, according to a new study, there’s something else we could be doing to prevent a stroke – increase our potassium intake.</p> <p><a href="http://www.einstein.yu.edu/news/releases/1039/potassium-rich-foods-cut-stroke-death-risk-among-older-women/" target="_blank"><strong><span style="text-decoration: underline;">A recent study</span></strong></a> of over 90,000 women between the ages of 50 and 70 from the Albert Einstein College of Medicine in New York found that those with high levels of potassium in their diet had a 12 per cent lower risk of stroke in general and 16 per cent lower risk of ischemic stroke.</p> <p>In women who didn’t suffer hypertension (high blood pressure), the benefit was even greater, reducing general stroke risk by 21 per cent and ischemic by 27 per cent.</p> <p>Researchers have previously linked high potassium intake with lower blood pressure, which may explain the reduced risk of stroke, but this study was the first to show that potassium itself reduces stroke risk.</p> <p>“We think the beneficial effects act through other pathways, beyond the effects on blood pressure,” lead author, epidemiologist Dr Sylvia Wassertheil-Smoller.</p> <p>“Our findings give women another reason to eat their fruits and vegetables. They're good sources of potassium, and potassium not only lowers postmenopausal women's risk of stroke, but also of death.”</p> <p>While it may be the nutrient’s poster fruit, potassium can be found in more than just banana. Potato, watermelon, leafy greens (think spinach and kale), beans, milk, yoghurt, pistachios, salmon, chicken breast and more also contain high levels of potassium.</p> <p>The Australian and New Zealand governments recommend a daily potassium intake of 3,800mg for men and 2,800 mg for women.</p>

Eating chocolate could reduce your risk of stroke and dementia by 20%

<p>If you couldn’t resist a square or two of chocolate last night, never fear – you could be saving your life. <a href="https://www.hsph.harvard.edu/news/press-releases/chocolate-irregular-heartbeat/" target="_blank"><strong><span style="text-decoration: underline;">A new study</span></strong></a> from researchers at Harvard University has found that eating moderate amounts of dark chocolate significantly lowers the risk of atrial fibrillation (AF) – an abnormal heart rate associated with stroke, heart failure and dementia.</p> <p>Scientists examined more than 55,000 Danish men and women, tracking their body mass index, blood pressure and cholesterol for 3.5 years. After identifying 3,346 cases of AF in the 13.5-year follow up period, they discovered that those who ate one to three 30g servings of chocolate per month had a 10 per cent lower rate of AF than those who had just one per month. Those who had one per week experienced a 17 per cent lower rate, while those who ate two to six servings per week has a 20 per cent lower rate.</p> <p>“We observed a significant association between eating chocolate and a lower risk of AF – suggesting that even small amounts of cocoa consumption can have a positive health impact,” lead researcher Elizabeth Mostofsky said.</p> <p>“Eating excessive amounts of chocolate is not recommended because many chocolate products are high in calories from sugar and fat and could lead to weight gain and other metabolic problems. But moderate intake of chocolate with high cocoa content may be a healthy choice.”</p> <p>So there you have it! As long as you don’t go overboard, it’s time to stop feeling guilty about those few bites of chocolate after dinner.</p>

Healthy people have strokes too

<p><em><strong>Margaret Cunningham, 61, is “semi-retired” from her role in digital communications. She is a hobby writer who particularly enjoys writing articles with a reflective viewpoint. A lifelong passion of health and fitness means she is known in her community as “that lady who runs.” </strong></em></p> <p>“Some things we can control and some things we cannot. In a split second your life changes forever. Your previous life is no longer, you are now on a different path.” – Unknown</p> <p>When I first spot Jennie Williamson at the gym two things stand out – her striking fluro-pink gym gear and the absolute focus and commitment she is putting into her training session. Jennie has just completed her twice weekly programme – four sets of 12-15 reps including chest presses, leg presses, dead lifts, leg extensions, lat pulldowns and core work – the list goes on and on. As a former fitness instructor and body building enthusiast, her workout should have been a doddle. That final dead-lift of 74kgs is impressive, but it’s not until Jennie releases the weight and walks away that you notice her left arm and leg weakness. In 2007 Jennie suffered a major stroke which affected the left side of her body, leaving her unable to walk. This is her story of recovery.</p> <p style="text-align: center;"><img width="500" height="889" src="https://oversixtydev.blob.core.windows.net/media/36888/jennie-1_500x889.jpg" alt="Jennie -1"/></p> <p>Fit and healthy people have strokes too. When you think of the ‘typical’ stroke patient, the mind readily drifts towards someone who is elderly, possibly overweight, has high blood pressure, doesn't exercise and probably smokes. Jennie, in her late 40s when she suffered her stroke – did not fit this picture. She lived and loved fitness.</p> <p>“I ran, did triathlons, body building as well as managing a garden centre. That’s my other passion - gardening. I didn’t drink or smoke and ate healthily. If it was physical, then I loved to do it,” she says.</p> <p>For the former Miss Bay of Plenty Fitness and holder of a New Zealand body building title Jennie’s stroke appeared unexpectedly and without warning.</p> <p>“I never had a day off work, but on this particular day I had been unwell with a sinus infection so had stayed home. I lay down for a nap and when I woke up I felt a stabbing pain in my head, my speech was garbled and my left side in spasm.  Not that I recognised it at the time, but I was having a stroke,” says Jennie.</p> <p>Jennie had suffered an ischemic stroke – one brought on by a clot in a blood vessel supplying blood to the brain. Unfortunately, Jennie missed the ‘golden hour’, a term used to describe the hour immediately following the onset of stroke symptoms, and didn’t receive the clot-busting drug TPA (tissue plasminogen activator). TPA is effective only for a few hours after a stroke. Time is brain – the sooner medical treatment begins; the more likely brain damage can be reduced and a better physical and mental outcome achieved.</p> <p>“Because I wasn’t an obvious stroke candidate doctors first associated my symptoms with a migraine. It was well over the four-hour mark before I was diagnosed with having a stroke. Had I been diagnosed sooner and received the clot-busting drug, things may have been different. I was very bitter about this for a long while.”</p> <p>Jennie spent three days in ICU and 10 weeks in hospital. The wonderful rapport she had built over the years in her Hawera community became evident in the early days of her stroke.</p> <p>“I loved it in hospital. Because it was a small town and I was well-known in the community as the ‘gardening lady’ I had plenty of visitors – it was a very social time for me and there was never a dull moment – always a crowd around my bed. Funnily enough going home was a struggle for me,” she recalls.</p> <p>Unable to walk due to the paralysis down her left side and dependant on her husband, who also worked a 12-hour day, for most of her care, Jennie struggled to come to terms with her ‘new life’.</p> <p>“I’m stuck in my wheelchair, looking out on my two-acre garden. I couldn’t drive and had to depend on people taking me places and doing everything for me. I couldn’t do anything.”</p> <p>For someone who thrived on independence this was a very difficult period.  I fell into a big black hole and revelled in my own misery for a long while,” says Jennie.</p> <p>It’s hard to imagine this when you talk to Jennie today. This vibrant, well-toned, fit looking wife and active grandmother is as busy today as she was pre-stroke. Jennie is adamant she wants this story to show that when a life changing event strikes, you can you pick yourself up again even if it looks and feels insurmountable at the beginning.</p> <p style="text-align: center;"><img width="498" height="280" src="https://oversixtydev.blob.core.windows.net/media/36887/jennie-2_498x280.jpg" alt="Jennie -2 (3)"/> </p> <p>Concerned about her spiralling depression Jennie’s husband John sought help from their doctor who recommended Jennie visit a grief counsellor. Jennie explains that people often think of grief as associated with death or the loss of a close family member or friend. However, grief can be a symptom of loss of all kinds. After a stroke, for the survivor, grief can be associated with loss of a way of life, mobility, confidence or independence. Jennie says working through the five stages of grief with a counsellor was the best thing that could have happened.</p> <p>“I was very woe is me, very bitter and negative. The struggle was mental as well as physical.  I didn’t realise I was grieving. Once I had accepted my loss I was able to move on.”  </p> <p>What really sticks out in Jennie’s mind through that dark period though are the stern but wise words from her husband John.</p> <p>“He said to me, ‘I’m sick and tired of hearing what you can’t do, look at the things you can do’. He was right. I could still speak, I could still think, I could still feel and I could still see. I had lots of friends and support. I was alive. All I had lost was my mobility and there was plenty I could do to work on that. I wanted to be a decent nana, a decent wife and a decent mother again.”</p> <p>Jennie moved from victim to survivor. From a wheelchair, to a walking frame to … well… just walking. Learning new skills, re-learning old skills. Rehabilitation after a stroke is about getting back to normal life and living as independent a life as possible. It involves taking an active approach to ensure life goes on. Because of Jennie’s fitness background she outgrew what stroke rehabilitation could offer and by this time Jennie saysshe just wanted to ‘get back out there’ and stop hiding herself away.</p> <p>Now living in the Bay of Plenty Jennie joined Ocean Blue Health and Fitness in Papamoa under the guidance of Personal Trainer, Kevin Bonds. Kevin, whose qualifications include specialising in pre and post rehabilitation, says that when Jennie first came to see him she was still using a walking frame. On her first visit and, much to Jennie’s horror, Kevin told her to leave the walking frame at the door saying he wanted her to focus on her ability, not her limitations.</p> <p>“I could see she feared falling, but I knew I could support her if she physically needed it rather than relying on the frame. I wanted her trust the process, be out of her comfort zone so she could adjust her mind to allow her body to do the task at hand and eventually have that trust transfer to herself,” says Kevin.</p> <p>Jennie’s rehabilitation program was, and is, focused around her enjoyment of life. Kevin says he wanted her to have the ability to do the everyday things she loved - going to the beach with her grandchildren, traveling to Beach Hops, spending time gardening, really living and thriving in her life again.  </p> <p>“To get there we focused on strength, balance and core and, as her body and mind got stronger, so did her confidence to accept new challenges. Every little improvement was a major milestone. Now that fear is no longer a factor for Jennie, the sky is the limit for her.”</p> <p>From victim to survivor to thriver. It’s been 10 years since her stroke and for Jennie rehabilitation will always be work in progress. Our interview is cut short because she needs to dash off to get groceries before she picks up the grandkids who are spending a week with her during the school holidays – now that’s thriving. <br /> <br /> <strong>Recognising a stroke</strong><br /> Common first signs of stroke include:</p> <ul> <li>Sudden weakness and/or numbness of face, arm and/or leg especially on one side of the body</li> <li>Sudden blurred or loss of vision in one or both eyes</li> <li>Sudden difficulty speaking or understanding what others are saying</li> <li>Sudden loss of balance or an unexplained fall or difficulty controlling movements, especially with any of the other signs</li> </ul> <p><strong>How you can tell if someone is having a stroke</strong><br />Use the FAST approach</p> <p>FACE – Is their face drooping on one side? Can they smile?<br /> ARM – Is one arm weak? Can they raise both arms?<br /> SPEECH – Is their speech jumbled or slurred? Can they speak at all?<br /> TIME – Time is critical.</p> <p>Stroke is always a medical emergency. Act FAST. Call NZ 111 or AUS 000</p>
