Stroke Warning Signs

  • 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



If you or someone with you has one or more of these signs, don't delay! Immediately call 911 or the emergency medical services (EMS) number so
an ambulance can be sent for you. It is very important to get to the hospital quickly! If given within three hours of the start of symptoms, a clot-busting
drug can reduce long-term disability for the most common type of stroke.

If a stroke warning sign occurs, what are the most important things to remember?

  • Do not ignore the warning signs, even if the symptoms go away! Some people may only have one or two signs. Others may have more.
  • Check the time. When did the first warning sign start? You will be asked this important question later.
  • Act quickly and call 911. Stroke is a medical emergency.
  • Every second counts. 

Write down the emergency medical services number and your physician's number and put them by your phone.
Remember, not every person has all the signs of stroke. When you see any of them, act quickly!
