Stroke meaning

A stroke is a medical emergency that occurs when the blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. This can lead to the death of brain cells within minutes. There are two main types of stroke: ischemic stroke, caused by a blockage in an artery, and hemorrhagic stroke, caused by the rupture of a blood vessel. Symptoms of a stroke include sudden weakness or numbness in the face, arm, or leg (particularly on one side of the body), confusion, trouble speaking, vision problems, dizziness, and severe headache. Prompt treatment is crucial to minimize brain damage and improve outcomes. Treatment options may include medications to dissolve clots, surgical interventions, and rehabilitation therapy to aid recovery.
