By learning and sharing the
F.A.S.T. warning signs, you just
might save a life from stroke.

Strokes can happen to anyone, at any age. In fact, globally about one in four adults over the age of 25 will have a stroke in their lifetime. Yet, most adults in the U.S. don’t know the F.A.S.T. warning signs of a stroke, and that stroke is largely preventable, treatable and beatable. Our power is knowledge and how we apply that knowledge starting today to defeat stroke.

Stroke is an EMERGENCY. Call 911 if these signs are present.

Hover—or click if you’re on your mobile—on the F.A.S.T. tiles.

Letter F
[F = FACE DROOPING] Does one side of the face droop, or is it numb? Ask the person to smile. Is the person's smile uneven?
letter A
[A = ARM WEAKNESS] Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward?
letter S
[S = SPEECH] Is speech slurred? Is the person unable to speak or hard to understand? Ask the person to repeat a simple sentence, like "The sky is blue."
Letter t
[T = TIME TO CALL 911] If you have any of these symptoms or see someone else having them, call 911 immediately!
