Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Scientists discover link between mutations in INPP5E gene and ciliopathies

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have discovered a connection between mutations in the INPP5E gene and ciliopathies. Their findings, which may lead to new therapies for these diseases, will appear in the online edition of Nature Genetics on August 9.

Stroke doubles patients' risk of breaking a hip or femur

Stroke survivors have about twice the risk of breaking a hip or femur compared to those without stroke - and the risk is even greater for younger patients, women and those with recent strokes, Dutch researchers report in Stroke: Journal of the American Heart Association.

Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

Tips to avoid heat stroke

The first sign of dangerous heat stroke can be just that – no sweat. As the temperature rises, your body’s natural cooling mechanism, sweat (or more kindly, perspiration), evaporates and helps to cool your body. But on those hot, humid cut-the-air-with-a knife days, evaporation is slowed and your body may not be able to keep itself cool.

Long-term brain damage after bypass surgery - more evidence puts blame on heart disease

Brain scientists and cardiac surgeons at Johns Hopkins have evidence from 227 heart bypass surgery patients that long-term memory losses and cognitive problems they experience are due to the underlying coronary artery disease itself and not ill after-effects from having used a heart-lung machine.

Anti-growth factor drugs raise hope and concern for treatment of children's eye diseases

A new class of antibody drugs may provide a powerful new tool for the treatment of eye diseases in children, but specialists need to be alert for the possibility of serious side effects, according to an editorial in the August Journal of AAPOS (American Association for Pediatric Ophthalmology and Strabismus), published by Elsevier.

Mortality rates higher in hepatitis C virus carriers

Hepatitis C virus (HCV) is a blood-borne disease that causes inflammation of the liver and to which there is currently no vaccine available. The World Health Organization (WHO) estimates that 3% of the world's population, approximately 170 million people, are infected with HCV and it is a leading cause of liver cirrhosis, end stage liver disease, hepatocellular carcinoma (HCC) and liver transplantation.

Plenty of dairy foods in childhood may mean a longer life

Milk is an excellent source of calcium and the children who ate plenty of dairy foods such as milk and cheese appeared to be protected against stroke and other causes of death, even though dairy products often contain fats and cholesterol which fur up the arteries and high consumption of dairy products did not raise the heart disease risk.

Hypertension may lead to ‘silent’ strokes

"Silent" strokes, which are strokes that don't result in any noticeable symptoms but cause brain damage, are common in people over 60, and especially in those with high blood pressure, according to a study published in the July 28, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Effect of sunlight exposure on cognitive function among depressed and non-depressed participants

A lack of sunlight is associated with reduced cognitive function among depressed people. Researchers writing in BioMed Central's open access journal Environmental Health used weather data from NASA satellites to measure sunlight exposure across the United States and linked this information to the prevalence of cognitive impairment in depressed people.
