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.

Disability does not necessarily follow disease in living to old age

Researchers from Boston Medical Center's (BMC) New England Centenarian Study report that for a substantial proportion of their centenarian subjects, avoiding age-related diseases (i.e. stroke, cardiovascular disease, diabetes) may not be the key to their longevity; rather, the avoidance of disability may be a key feature in their exceptional survival.
