STROKE: Remember the 1st Three Letters: S.T.R.
S Ask the person to SMILE. <if crooked or drooping call 911>
T Ask the person to TALK and SPEAK A SIMPLE SENTENCE (Coherently, i.e. It is sunny out today) <if voice is garbled or words mis-used call 911>
R Ask the person to RAISE BOTH ARMS <if unable to raise them equally call 911>
New Sign of a Stroke -- Stick out Your Tongue: If the tongue is 'crooked', if it goes to one side or the other, that is also an indication of a stroke.
If the person has trouble with ANY of these tasks, Call 9-1-1 immediately and describe the symptoms to the dispatcher.
