A stroke, or cerebrovascular accident, occurs when the blood supply to the brain is cut off (an ischemic stroke) or when a blood vessel leading to or within the brain bursts (a hemorrhagic stroke). Without oxygen, brain cells begin to die. Death or permanent disability can result.
With timely treatment, the risk of death and disability from stroke can be lowered. It is very important to know the symptoms of a stroke and act right away.
The National Institute of Neurological Disorders and Stroke notes 5 major signs of stroke:
- Sudden numbness or weakness of the face, arms, or legs.
- Sudden confusion or trouble speaking or understanding others.
- Sudden trouble seeing in one or both eyes.
- Sudden trouble walking, dizziness, or loss of balance or coordination.
- Sudden severe headache with no known cause.
All of the major symptoms of stroke appear suddenly, and often there is more than one symptom at the same time.
If you think someone is having a stroke, you should call 9-1-1 or emergency medical services immediately. Receiving immediate treatment is critical in lowering the risk of disability and even death.
