A stroke is cell death caused by poor blood supply to the brain. It will result in part of the brain not functioning properly. Stroke can be divided into two types: ischemic due to lack of blood flow and hemorrhagic due to bleeding. The focal cerebral ischemic model of stroke is commonly used to evaluate ischemic injury of the brain. Signs and symptoms of a stroke may include:
Trouble with speaking and understanding
Trouble with walking
Trouble with seeing in one or both eyes
Paralysis or numbness of the face, arm or leg
