What are the signs that I might be having a stroke?

The acronym FAST—face, arm, speech, time—is a good tool for diagnosing a stroke.

Typical warning signs of a stroke develop suddenly and can include:

  • weakness or numbness on one side of the body
  • sudden confusion or trouble understanding
  • trouble talking
  • dizziness, loss of balance or trouble walking
  • trouble seeing out of one or both eyes
  • double vision
  • severe headache

If you have warning signs of a stroke, call 9-1-1 right away. Getting treatment as soon as possible after a stroke can help prevent permanent damage to your brain.

The easiest thing to remember when you need to identify a stroke is FAST: face, arm, speech and time.
