Three steps -- S-T-R

S - Ask the individual to SMILE

T - Ask the person to TALK or SPEAK A SIMPLE SENTENCE ( Coherently - i.e. It is sunny out today.)

R - Ask him or her to RAISE BOTH ARMS

Note:  Another 'sign' of a stroke is this:  Ask the person to 'stick' out their tongue.  If the tongue is 'crooked', if it goes to one side or the other, that is also an indication of a stroke.  If he or she has trouble with ANY ONE of these tasks, call 911 immediately, and describe the symptoms to the dispatcher!
