Stroke News

A stroke is a medical emergency that occurs when the blood supply to a part of the brain is interrupted or significantly reduced, depriving brain tissue of oxygen and nutrients. This interruption can lead to the rapid death of brain cells, causing various neurological impairments. There are two main types of strokes: ischemic stroke, caused by a blockage in an artery due to a blood clot, and hemorrhagic stroke, caused by a rupture of a blood vessel leading to bleeding in or around the brain. Symptoms of a stroke include sudden numbness or weakness in the face, arm, or leg (especially on one side of the body), confusion, trouble speaking or understanding speech, difficulty seeing in one or both eyes, difficulty walking, dizziness, loss of balance, and severe headache with no known cause. Prompt medical treatment is crucial, as early intervention can significantly improve the outcome and reduce the risk of long-term disability. Treatments may involve clot-dissolving medications, surgical interventions, and rehabilitation therapies. Preventative measures include managing risk factors such as high blood pressure, diabetes, high cholesterol, smoking, and maintaining a healthy lifestyle with regular exercise and a balanced diet.
