10 Early Warning Signs of a Stroke Everyone Should Know to Take Prompt Action
A stroke happens when blood flow to part of the brain is blocked (ischemic stroke) or when a blood vessel in the brain bursts (hemorrhagic stroke). Because brain cells can be damaged quickly when oxygen is cut off, recognizing symptoms and getting emergency help immediately can make a major difference.
A helpful way to remember common warning signs is FAST:
- F — Face drooping: One side of the face may feel weak or numb. Ask the person to smile—does one side droop?
- A — Arm weakness: One arm may become weak or numb. Ask the person to raise both arms—does one drift downward?
- S — Speech difficulty: Speech may become slurred, strange, or difficult to understand.
- T — Time to call emergency services: Do not wait to see if symptoms improve.
