If you suspect someone is having a stroke, it is important to act quickly. The National Stroke Association says the word FAST is an easy way to remember the signs and symptoms of a stroke. F is for face. Ask the person to smile. Does one side of his face droop? A is for arms. Ask him to raise both arms. Does one arm drift downward? S is for speech. Ask the person to repeat a simple phrase. Is his speech slurred or strange? T is for time. If you observe any of these signs, call 911 immediately. Do not wait. Stroke is an emergency.Note the time when symptoms began, because there are clot-busting drugs that can reduce a stroke’s effects if they’re given within three hours. When in doubt, call 911. It can save someone’s life.
