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 zero in on the cellular machinery that enables neurons to fire

Toy robots with removable body parts - you probably had fun swapping their heads, imagining how it would affect their behavior. Scientists supported by the National Institutes of Health have been performing similar experiments on ion channels - pores in our nerve cells - to sort out the channels' key functional parts.

Overexpression of neuroglobin reduces severity of Alzheimer's disease in mice

Mice genetically engineered to both overproduce the protein neuroglobin and to develop Alzheimer's disease (AD) had a much milder form of the disease when compared to mice engineered to have AD alone, researchers at the Buck Institute for Age Research have reported.

Optical non-invasive tool to test for decompression sickness

It may not rank among the top 10 causes of death, but decompression sickness can be fatal. Instead of waiting for symptoms to appear, a University of Houston professor is developing a laser-based system that can diagnose the sickness in a matter of seconds.
