F = Face Drooping. During a stroke, one side of the face often sags or feels numb. Ask the person to smile, Saver suggests. If the smile is lopsided or uneven, that’s evidence of a stroke.A = Arm Weakness. Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward? That’s another warning sign.S = Speech Difficulty. If speech is slurred or nonsensical, that’s a red flag, Saver explains. He suggests asking the person to repeat a simple sentence like, “The sky is blue.” If the sentence isn’t repeated correctly, that’s another indicator.T = Time to call 9-1-1. “If someone shows any of these symptoms, even if the symptoms go away, call 9-1-1 and get the person to the hospital immediately,” Saver says. “And check the time so you’ll know when the symptoms first appeared.”
