Signs of Stroke

A stroke is caused when blood flow to the brain is disrupted. Disruption in blood flow occurs when either a blood clot blocks one of the vital blood vessels in the brain (ischemic stroke), or when a blood vessel in the brain ruptures, causing reduced blood supply to the brain (hemorrhagic stroke).

Symptoms of a stroke include sudden onset of:

  • Numbness or weakness on one side of your body or face
  • confusion or difficulty speaking
  • vision loss
  • dizziness or imbalance
  • severe headache

For more information, contact The Johns Hopkins Hospital Stroke Center at 410-955-2228.
If you have questions about the Stroke Prevention and Recovery Center, please call us at 443-287-8514.

A stroke is a medical emergency. It is critical to recognize the signs of a stroke. The greatest chance for recovery from stroke occurs when treatment is started immediately. Should you experience any of these symptoms, please call 911 and immediately go to the hospital.
