Stroke: Know the Signs. Act in Time.
A stroke happens when there is a loss of blood flow to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die within a few minutes. This can cause lasting brain damage, long-term disability, or even death.
Stroke is a medical emergency and every minute counts. If you think that you or someone else is having a stroke, call 9-1-1 right away.
Symptoms of a stroke often appear suddenly. They include:
- numbness or weakness of the face, arm, or leg (especially on one side of the body)
- confusion, trouble speaking, or understanding speech
- trouble seeing in one or both eyes
- trouble walking, dizziness, loss of balance coordination
- severe headache with no known cause
Immediate treatment may save someone's life and increase the chances for successful rehabilitation and recovery.
