RECOGNIZING A STROKE: STR If something is amiss:
S = SMILE Ask the person to SMILE. T = TALK Ask the person to say a simple sentence, like "I like ice cream." R = RAISE BOTH ARMS Ask the person to raise both arms.
Trouble with any one of the above tasks is reason enough to call an ambulance and describe the symptoms to the dispatcher.
NOTE : Another 'sign' of a stroke is a crooked tongue. Ask the person to stick out their tongue and if it's crooked (meaning it goes to one side), it could mean the person is having a stroke.
