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.

Breakdown of myelin may be the cause of Huntington's disease

Last month, Dr. George Bartzokis, director of the UCLA Memory Disorders and Alzheimer's Disease Clinic, suggested in the journal Alzheimer's & Dementia that the breakdown of a type of myelin that develops late in life promotes the buildup of toxic amyloid plaques long associated with Alzheimer's disease.

Researchers discover how strokes trigger biochemical events that increase amyloid-beta production in the brain

Researchers from the MassGeneral Institute for Neurodegenerative Disorders (MGH-MIND) have discovered how the death of brain cells caused by a stroke or head injury may cause generation of amyloid-beta protein ? the key component of senile plaques seen in the brains of patients with Alzheimer's disease.

Standards for the use of ultrasound to measure narrowing of the carotid artery may be too aggressive

These standards, used by the majority of vascular laboratories around the country since the early 1980s, were based on the use of angiography, a medical imaging technique in which an X-ray picture is taken to visualize the inner opening of blood filled structures.
