The National Stroke Association recommends using the FAST acronym to help remember the warning signs of stroke
F = FACE: Ask the person to smile. Does one side of the face droop?
A = ARMS: Ask the person to raise both arms. Does one arm drift downward?
S = SPEECH: Ask the person to repeat a simple phrase. Does their speech sound slurred or strange?
T = TIME: If you observe any of these signs, call 9-1-1 immediately.
