Knowing the warning signs of a stroke is important because many strokes can be prevented. People should call 911 and get medical attention right away if they or someone they know are having any of the following symptoms.
- 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.
What to do
- Immediately call 9-1-1
- Know when the symptoms first appeared
If given within three hours of the start of symptoms, a clot-busting drug called plasminogen activator (tPA) can reduce long-term disability for the most common type of stroke. tPA is the only FDA-approved medication for the treatment of stroke within three hours of stroke symptom onset.
