What is a stroke?
A stroke is an interruption in blood flow to the brain. The block can be caused by a block or breaking of an artery supplying blood to the brain tissue.
• Without blood supply, brain tissue begins to die within minutes.
• Signs and symptoms of a stroke depend on what part of the brain is affected.
Warning signs of a stroke (warning signs are sudden):
- Uneven smile
- Weakness or numbness on one side of body
- Confused or slurred speech
- Vision loss
- Trouble walking
- Sudden, severe headache
What should you do if someone is having a stroke?
If you believe someone is having a stroke- if he or she suddenly loses the ability to speak, or move an arm or leg on one side, or experiences facial paralysis on one side- call 911 immediately.
