Stroke

S * Ask the individual to SMILE ..
T * = TALK. Ask the person to SPEAK A SIMPLE SENTENCE (Coherently) (eg 'It is sunny out today').
R * Ask him or her to RAISE BOTH ARMS .

If he or she has trouble with ANY ONE of these tasks, call the ambulance and describe the symptoms to the dispatcher.

NOTE : Another 'sign' of a stroke is
1. Ask the person to 'stick' out their tongue.
2. If the tongue is 'crooked', if it goes to one side or the other that is also an indication of a stroke.
