Signs & Symptoms of Stroke

Stroke survivors are at an increased risk for another stroke. Knowing the warning signs for stroke may help save your life or the life of someone you love. And, getting quick treatment may improve the chances of survival and getting better faster.

The signs or symptoms of a stroke can appear suddenly. Not every person has all of them. When you see any of them, act quickly.


The signs or symptoms of a stroke are:

  • 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 stroke warning signs occur:

  • Do not ignore them, even if they go away! Some people may have only one or two signs. Other people may have more.
  • Check the time when the symptoms first started. You will be asked this important question later.
  • Act fast. Call 911 or your emergency response number right away.

Stroke is a medical emergency. Every second counts!
