A cerebrovascular accident (CVA), commonly known as a stroke, can be caused by two primary mechanisms: ischemia and hemorrhage. Ischemic strokes occur when a blood vessel supplying blood to the brain is blocked, often due to a clot, which can result from conditions like atherosclerosis or atrial fibrillation. Hemorrhagic strokes happen when a blood vessel in the brain ruptures, leading to bleeding, and can be caused by factors such as high blood pressure or aneurysms. Other risk factors include Diabetes, smoking, and high cholesterol levels.
