Symptoms of Stroke
Symptoms of stroke occur when blood supply to part of your brain is interrupted. They can occur suddenly and differ depending on the part of the brain that is affected. Multiple symptoms can happen together because the blocked or bleeding blood vessels may supply a large enough area of the brain that includes multiple functions. Anything your brain does may be affected. If you experience any of the symptoms listed below in alone or together, call for emergency medical services right away.
