Strokes occur when the blood vessels that supply the brain with blood and oxygen become blocked, or when a blood vessel within the brain ruptures. Cells in the brain die as a result of a lack of blood and oxygen. A stroke requires immediate medical attention. The faster you receive care, the better your chances for survival and reducing brain damage. The initial signs of a stroke may be subtle, not last long and be hard to recognize. If you experience symptoms of a stroke, seek medical care immediately.
