A stroke happens when there is a disruption or reduction in the blood supply to a portion of the brain, depriving the brain tissue of nutrition and oxygen. Within minutes, this may result in the loss of brain cells. Strokes can be classed as ischemic (caused by an artery blockage) or hemorrhagic (caused by a burst blood vessel). Strokes are a primary cause of disability and death globally. Frequent signs and symptoms include abrupt weakness or numbness, usually on one side of the body, disorientation, difficulty speaking, and problems seeing or moving.
For stroke victims, receiving prompt medical attention is essential to reducing brain damage and enhancing their prognosis. Treatment for strokes might vary based on the kind and may involve blood vessel damage repair surgery, medication to break up clots, and rehabilitation to restore lost abilities. The chance of having a stroke can be considerably decreased by taking preventive actions, such as controlling risk factors like diabetes, and high blood pressure, and lifestyle modifications.
