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.

Technique to visualize changes in nerve connections when flies learn may help to understand how memories form

For the first time, researchers have used a technique called optical imaging to visualize changes in nerve connections when flies learn. These changes may be the beginning of a complex chain of events that leads to formation of lasting memories.

The Stroke Association have found that surgery can halve the risk of a stroke

Scientists funded by the Medical Research Council (MRC) and The Stroke Association have found that surgery can halve the risk of a stroke for people who have significant narrowing of the main artery carrying blood to the brain. Their findings, published in this week’s The Lancet, are the result of a large-scale international clinical trial.

Small, frequent doses of caffeine best strategy for staying awake

Caffeine is the world's most widely-used stimulant yet, scientists still do not know exactly how it staves off sleep. Researchers at Brigham and Women's Hospital, Harvard Medical School and other institutions have now discovered that caffeine works by thwarting one of two interacting physiological systems that govern the human sleep-wake cycle.

Critical link found between inflammation, heart disease and stroke
