What is a brain attack?
A brain attack (stroke) damages the brain just as a heart attack damages the heart. Both are medical emergencies. Symptoms include sudden onset of:
- numbness or weakness of the face, arm or leg, especially on one side of the body;
- confusion or trouble speaking/understanding;
- trouble seeing in one or both eyes;
- trouble walking, dizziness, loss of balance or coordination; or
- severe headache with no known cause.
A stroke occurs when the flow of blood to the brain is blocked. A stroke can be caused by a clot in a blood vessel or artery (ischemic stroke) or by a ruptured or burst blood vessel (hemorrhagic stroke). Strokes occurring from clogged vessels are more common and account for 83 percent of all strokes. Fast treatment can save a life.
