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.

Study finds darapladib lowers biomarker for cardiovascular problems

Despite widespread use of cholesterol-lowering drugs, a significant number of cardiac patients continue to suffer heart attacks and stroke. Researchers theorize that high levels of an enzyme found in coronary plaques may be to blame, by making plaques more likely to rupture and block blood flow. The drug darapladib may offer a way to fight that risk, according to new research led by the University of Pennsylvania School of Medicine.

Better-educated women have healthier average weight

A new comparison of multi-national data, released this month, reveals that highly educated women have a healthier average weight than less educated women, but that the meaning of "healthier" changes according to a nation's relative wealth. In countries where malnutrition is prevalent, better-educated women weigh more. But in wealthier countries - with rapidly growing rates of obesity - better-educated women weigh less.

Clearer understanding of how neurons give rise to motor behaviors

When the eye tracks a bird's flight across the sky, the visual experience is normally smooth, without interruption. But underlying this behavior is a complex coordination of neurons that has remained mysterious to scientists. Now, UCSF researchers have broken ground in understanding how the brain generates this tracking motion, a finding that offers a window, they say, into how neurons orchestrate all of the body's movements.
