Know the Symptoms

Being able to recognize the symptoms of a stroke is critical. Act FAST is a simple tool to help you learn and remember stroke symptoms so you know when to seek medical attention for yourself or someone else.

Remember the word “FAST” and call 911 if you notice any of these symptoms of stroke:


  • Uneven smile
  • Numbness or tingling
  • Vision problem


  • Weakness or paralysis
  • Numbness
  • Difficulty walking


  • Slurred speech
  • Inappropriate words
  • Unable to speak


  • Call 911 immediately

Make sure your family members, co-workers and friends know about Act FAST, too. The more people who Act FAST in cases of stroke, the more lives that can be saved – and the fewer people who may have to cope with lifelong disability.
