A stroke is a sudden loss of brain function that occurs when the blood flow supplying oxygen to a part of the brain is interrupted. There are three major types of stroke: ischemic stroke which is caused by a lack of blood flow to the brain due to a blood clot; bleeding within the brain; and a rupture of an aneurysm in a blood vessel in the brain.
