A stroke is a potentially fatal disorder that occurs when blood flow is cut off to a portion of the brain for an extended period of time. The most common causes of this condition are a blood vessel in the brain becoming clogged or bleeding in the brain itself. If that region of the brain does not receive a consistent supply of blood, the brain cells in that region begin to die due to a lack of oxygen.
