Certain gut microbes may affect stroke risk and severity, scientists find
Studies of ischaemic stroke patients open up possibility of treatments to prevent condition and improve recoveryScientists have identified specific groups of gut microbes that could increase or decrease someone ’s risk of suffering the most common type of stroke. The research, presented at the European Stroke Organisation Conference (ESOC) in Lyon, France, adds to growing evidence that alterations in the gut microbiome could play a role in cardiovascular disease.Previous studies have suggested that certain microbes may influence the formation of atherosclerotic plaques in the arteries, and that the gut microbiomes of str...

Deadly spider venom could ward off stroke brain damage, say doctors
Ingredient in funnel web spider venom can protect cells from being destroyed by a stroke, even when given hours after the event, study showsDoctors have stumbled on an unlikely source for a drug to ward off brain damage caused by strokes: the venom of one of the deadliest spiders in the world.A bite from an Australian funnel web spider cankill a human in 15 minutes, but a harmless ingredient found in the venom can protect brain cells from being destroyed by a stroke, even when given hours after the event, scientists say.Continue reading...

Supermarket trolley sensors could help to identify risk of stroke, say scientists
Study with 2,155 participants at Sainsbury ’s stores leads to atrial fibrillation diagnosis for 39 people unaware they had conditionSupermarket trolleys may be known for their wonky wheels and rusty frames, but researchers say the carts could be used to save lives by helping to identify people at risk of stroke through sensors in their handles.According to the British Heart Foundation, one in 45 people in the UK are living with atrial fibrillation (AF), which causes an abnormal heart rhythm and can increase the risk of stroke. While people may be unaware they have the condition, early detection and diagnosis is important...

Skin patch costing 39p could save lives of stroke victims, researchers say
Trials show patch significantly increases chances of survival when rapidly applied by paramedics during journey to hospitalA skin patch costing as little as 39p could revolutionisestroke treatment, significantly increasing the chances of survival, researchers have found.The patch contains glyceryl trinitrate (GTN), which lowers blood pressure and opens up blood vessels, helping reduce the damage caused in the immediate minutes and hours following a stroke.Continue reading...

Eating cheese does not raise risk of heart attack or stroke, study finds
Consumption of even full-fat dairy products does not increase risk, international team of experts saysConsuming cheese, milk and yoghurt – even full-fat versions – does not increase the risk of a heart attack or stroke, according to research that challenges the widely held belief that dairy products can damage health.The findings, from an international team of experts, contradict the view that dairy products can be harmful because of their high saturated fat content. The experts dismiss that fear as “a misconception [and] mistaken belief”.Continue reading...

MRI scan that can predict stroke risk has 'promise to save lives'
Scientists at Oxford University develop non-invasive technique to measure amount of cholesterol in carotid plaquesA new type of MRI scan can predict the risk of having astroke, researchers have said in a study.The non-invasive technique, developed by scientists at the University of Oxford, predicts whether plaques in the carotid arteries are rich in cholesterol and therefore more likely to cause a stroke.Continue reading...

Stroke: when words fail you
As BBC4 film Speechless marks World Stroke Day, documentary producer Nick Fraser reflects on his own recovery following a brain attack in FebruaryI was just finishing a talk about documentaries I was giving in Soho. I ’d been asked a question about why so many films are seriously depressing. I remember that I talked about the great neurosurgeon Henry Marsh and the documentary about him,The English Surgeon. The film followed him to Ukraine as he helped and taught the local surgeons, who often resorted to using rusty domestic power tools to work on their patients ’ skulls. I’d talked about him for some time, enthusiast...

Blood-thinning drugs designed to cut stroke risk may actually increase it
Scientists call for caution in prescribing anticoagulants after some patients with other conditions found to suffer more strokesBlood-thinning drugs may increase rather than cut the risk of stroke in some people over 65 who have an irregular heartbeat and also chronic kidney disease, according to a new study.The researchers are calling on doctors to be more cautious in prescribing the drugs, called anticoagulants, until there has been more research.Continue reading...

Scientists seek drug to ‘rewire’ adult brain after stroke
Therapies may one day enable healthy part of brain to take over tasks from damaged areasAdults who have experienced a stroke may one day be able to take a drug to help their brain “rewire” itself, so that tasks once carried out by now-damaged areas can be taken over by other regions, researchers have claimed.The ability for the brain to rewire, so-called “brain plasticity”, is thought to occur throughout life; however, while children have a high degree of brain plasticity, adult brains are generally thought to be less plastic.Continue reading...

New blood test predicts risk of heart attack and stroke with twice previous accuracy
New technique, already available in US, could aid in development of cardiovascular drugsScientists have developed a blood test that can predict whether someone is at high risk of a heart attack, stroke, heart failure or dying from one of these conditions within the next four years.The test, which relies of measurements of proteins in the blood, has roughly twice the accuracy of existing risk scores. It could enable doctors to determine whether patients ’ existing medications are working or whether they need additional drugs to reduce their risk.Continue reading...

Spinal nerve cell stimulation found to help stroke patients restore movement
Researchers say they have found a way to help survivors regain control of their arms and handsWhen Heather Rendulic experienced a series of strokes in 2012 at the age of 22, she lost functional use of her left hand. A decade later, she is once more able to use a fork and knife, thanks to electrodes implanted in her neck.About one in four people globally will experience a stroke in their lifetime – a condition in which the blood supply to part of the brain is cut off.Continue reading...
