Study of teenage drinkers and smokers shows 'significant damage' to arteries
Teenagers who smoke or consume alcohol have much stiffer arteries than those who don ’t, putting them on the path to heart disease and strokeThe arteries of teenagers who binge drink or smoke are already stiffer by the age of 17 than in those who abstain, new research has revealed.Arterial stiffness indicates damage to the blood vessels. Research in older adults has previously shown that the stiffening of arteries is linked to heart and circulatory disease and an increased risk of events such as heart attack or stroke. While our arteries stiffen as we age, it is known that a host of behaviours are linked to the effect, i...

Six to eight hours of sleep best for the heart, says study
Research shows sleep deprivation or excessive hours in bed increase risk of coronary artery disease or strokeSix to eight hours of sleep a night is most beneficial for the heart, while more or less than that could increase the risk of coronary artery disease or a stroke, researchers have suggested.The study, presented at the European Society of Cardiology Congress in Munich, indicates sleep deprivation and excessive hours in bed should be avoided for optimum heart health.Continue reading...

Salt not as damaging to health as previously thought, says study
New research reignites a row with scientists who want to reduce salt intake to near zeroSalt may not be as damaging to health as is usually claimed, according to a controversial new study which suggests campaigns to persuade people to cut down may only be worthwhile in countries with very high sodium consumption, such as China.The World Health Organization recommends cutting sodium intake to no more than 2g a day – the equivalent of 5g of salt – because of the link to increased blood pressure, which is in turn implicated in stroke.Continue reading...

Air pollution linked to changes in heart structure
Study shows correlation between levels of exposure to fine particulate matter and chamber enlargement seen in early stages of heart failureAir pollution is linked to changes in the structure of the heart of the sort seen in early stages of heart failure, say researchers.The finding could help explain the increased number of deaths seen in areas with high levels of dirty air. For example, a report last year revealed that people in the UK are64 times more likely to die from the effect of air pollution than people living in Sweden. Such premature deaths can be linked toa number of causes includingrespiratory problems,stroke a...

Omega-3 no protection against heart attack or strokes, say scientists
Supplements do not offer cardiovascular benefits, researchers conclude from trials involving 112,000 peopleThe widespread belief that taking omega-3 capsules will help protect you from a heart attack, stroke or early death is wrong, according to a large and comprehensive review of the evidence.Thousands of people take omega-3 supplements regularly and for years. The belief that it protects the heart has spread – and is promoted in the marketing of the supplements – because the results from early trials suggested the capsules had cardiovascular benefits.Continue reading...

Work stress raises risk of premature death in vulnerable men - study
Men with diabetes or heart disease under ‘job strain’ have 68% higher risk of early deathA major study into the impact of work stress on health has revealed dramatic differences in the rates of premature death between different groups of men, and between men and women, depending on existing medical conditions.Doctors found that men with diabetes, heart disease, or who had previously suffered a stroke, were 68% more likely to die over the course of the study if they had demanding jobs with little control over their workload.Continue reading...

Sinclair Lough obituary
My friend and former colleague Sinclair Lough, who has died aged 62 following a stroke, was a clinical psychologist who specialised in the care of older people.I first met Sinclair at theFaculty of the Psychology of Older People conference in Birmingham in 2000, where he was giving a talk onfrontotemporal dementia. This was in the days before PowerPoint and Sinclair was struggling with a projector, but it quickly became apparent that he was more than able to talk about the subject without the slides.Continue reading...

Neurosurgeon Eric Leuthardt: ‘An interface between mind and machine will happen’
The US researcher – and sci-fi author – on how brain implants will drive the next turning point in human evolutionDr Eric C Leuthardt, 45, is a neurosurgeon at Washington University in St Louis. He is also the co-founder of NeuroLutions, a research laboratory developing directinterfaces between mind and computer. Leuthardt is pioneering the use of electrical brain implants to help restore motor function to the paralysed limbs of stroke victims. He is also helping to develop electrode systems that can directly decode the unspoken “inner voice” of the mind, and use it to direct external action; for example, Leuthardt...

Extra glass of wine a day 'will shorten your life by 30 minutes'
Drinking is as harmful as smoking, and more than five drinks a week lowers life expectancy, say researchersDrinking will shorten your life, according to a study that suggests every glass of wine or pint of beer over the daily recommended limit will cut half an hour from the expected lifespan of a 40-year-old.Those who think a glass of red wine every evening will help keep the heart healthy will be dismayed. The paper,published in the Lancet medical journal, says five standard 175ml glasses of wine or five pints a week is the upper safe limit – about 100g of alcohol, or 12.5 units in total. More than that raises the risk ...

They warn of the urgent need to check the spread of cancers, diabetes, heart...

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...
