Stroke, also known as stroke, is an acute cerebrovascular disease, which is a group of diseases that cause brain tissue damage due to sudden rupture or blockage of blood vessels in the brain, including ischemic stroke and hemorrhagic stroke. Hemorrhagic stroke, which is what we call cerebral hemorrhage, is mostly caused by hypertension, but there are also some patients with cerebral hemorrhage caused by vascular amyloidosis or aneurysm. Another situation is ischemic stroke, which is what we call cerebral infarction. This situation is generally caused by multiple factors such as age, hypertension, heart disease or diabetes, which causes vascular stenosis and occlusion, thus causing cerebral infarction.
