Few people know the symptoms of stroke. Learning them could save your life or the life of a loved one.

F.A.S.T. is a simple test to help you recognize stroke symptoms:

F = FACE--Ask the person to smile; A = ARMS--Ask them to raise both arms; S = SPEECH--Ask them to repeat a simple sentence; T = TIME--Call 911 if the person has trouble with any of these tasks. Describe their symptoms to the dispatcher. Mention the possibility of stroke. If there is any doubt, don't wait; call 911. Remember, strokes strike fast.
