Here is some information on stroke from the American Heart Association:
Stroke Warning Signs
If you notice one or more of these signs, don't wait. Stroke is a medical emergency. Call 9-1-1 or your emergency medical services. Get to a hospital right away!
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.
