Hypertension is not the only cause of cerebral hemorrhage, the causes of cerebral hemorrhage also include cerebral amyloid angiopathy, cerebrovascular malformation, and other diseases. 1. Cerebral amyloid angiopathy: about 3% of spontaneous intracerebral hemorrhage is caused by amyloidosis, which occurs in the lobe of the brain near the cerebral cortex and is frequent. It is more common in the posterior part of the brain. 2. Cerebrovascular malformation: such as aneurysm, arteriovenous malformation, arteriovenous fistula, cavernous hemangioma, smoky disease, etc., which can lead to spontaneous intracerebral hemorrhage. 3. Other diseases: such as leukemia, thrombocytopenic purpura and other hematologic diseases, after the use of anticoagulant or antithrombotic drugs, vasculitis and other diseases may also occur when spontaneous cerebral hemorrhage. When cerebral hemorrhage occurs, immediate medical treatment should be sought.
