The American Stroke Association wants you to learn the warning signs of stroke:

• Sudden numbness or weakness of the face, arm or leg, especially on one side of the body
• Sudden confusion, trouble speaking or understanding
• Sudden trouble seeing in one or both eyes
• Sudden trouble walking, dizziness, loss of balance or coordination
• Sudden, severe headache with no known cause

Be prepared for an emergency.

• Keep a list of emergency rescue service numbers next to the telephone and in your pocket, wallet or purse.
• Find out which area hospitals are primary stroke centers that have 24-hour emergency stroke care.
• Know (in advance) which hospital or medical facility is nearest your home or office.

Take action in an emergency.

• Not all the warning signs occur in every stroke. Don't ignore signs of stroke, even if they go away!
• Check the time. When did the first warning sign or symptom start? You'll be asked this important question later.
• If you have one or more stroke symptoms that last more than a few minutes, don't delay! Immediately call 9-1-1 or the emergency medical service (EMS) number so an ambulance (ideally with advanced life support) can quickly be sent for you.
• If you're with someone who may be having stroke symptoms, immediately call 9-1-1 or the EMS. Expect the person to protest — denial is common. Don't take "no" for an answer. Insist on taking prompt action.
