Recognize the Warning Signs of a Stroke

When a person has a stroke, blood fails to reach brain cells as a result of a blood clot or bleeding in the brain.  Emergency care can save a patient from long-term damage and death. Act F.A.S.T. to increase recognition and response to stroke symptoms.


Ask the person to smile.  Does one side of the face droop?


Ask the person to raise both arms.  Does one arm drift downward?


Ask the person to repeat a simple phrase.  Does the speech sound slurred or strange?


If you observe any of these signs, it's time to call 9-1-1.
