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.

Vascular anatomy influences experimental stroke treatment effectiveness

A preclinical study from Duke University researchers suggests that the effectiveness of an experimental approach to limiting stroke-related brain injury may depend not only on the drug itself, but also on the brain's collateral circulation: the network of small "backup" blood vessels that can help sustain tissue when a major artery is blocked.
