Stroke Support Group
A stroke is an acute neurologic injury where the blood supply to a part of the brain is interrupted, either by a clot in the artery or if the artery bursts. The brain perfused by that artery no longer receiving oxygen carried by the blood and dying with cessation of function from that part of the brain.
