A stroke is a medical emergency that occurs when the blood flow to a part of the brain is interrupted or reduced, depriving brain cells of oxygen and nutrients. This can lead to the death of brain cells and potentially serious neurological damage. The symptoms of a stroke can include sudden weakness or numbness in the face, arms, or legs, difficulty speaking or understanding speech, loss of vision or blurred vision, severe headache, dizziness, or loss of balance or coordination. Treatment for a stroke usually involves emergency medical care to restore blood flow to the affected area of the brain, prevent further damage, and reduce the risk of complications. Rehabilitation and ongoing medical care may also be necessary to help patients recover from the effects of a stroke.
