What is a Stroke?
A stroke, or "brain attack," occurs when a brain artery ruptures or becomes blocked, cutting off vital supplies of blood and oxygen.
Brain cells deprived of oxygen can die within minutes, resulting in a loss of physical and mental functions, such as speech, sight,
sense of touch and thought processing. Damage often is permanent, as the body does not replace brain cells.
Ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel in the brain.
Hemorrhagic stroke occurs when a blood vessel bursts in or around the brain.
