The loss of blood flow to the brain damages tissues within the brain. Symptoms of a stroke show up in the body parts controlled by the damaged areas of the brain.
The sooner a person having a stroke gets care, the better their outcome is likely to be. For this reason, it’s helpful to know the signs of a stroke so you can act quickly. Stroke symptoms can include:
- numbness or weakness in the arm, face, and leg, especially on one side of the body
- trouble speaking or understanding others
- slurred speech
- confusion, disorientation, or lack of responsiveness
- sudden behavioral changes, especially increased agitation
- vision problems, such as trouble seeing in one or both eyes with vision blackened or blurred, or double vision
- trouble walking
- loss of balance or coordination
- severe, sudden headache with an unknown cause
- nausea or vomiting
A stroke requires immediate medical attention. If you think you or someone else is having a stroke, call 911 or local emergency services right away. Prompt treatment is key to preventing the following outcomes:
- brain damage
- long-term disability
It’s better to be overly cautious when dealing with a stroke, so don’t be afraid to get emergency medical help if you think you recognize the signs of a stroke.
