People without hypertension can also get cerebral hemorrhage, which is an acute hemorrhagic cerebrovascular disease that occurs mostly in middle-aged and elderly people. It is commonly caused by hypertension and can also be caused by rupture of an aneurysm or arteriovenous malformation. If the patient has abnormal vascular network disease at the base of the brain, it is also likely to cause cerebral hemorrhage. It can also be seen in cerebrovascular amyloidosis, and if the patient has severe platelet drop, he or she is also prone to cerebral hemorrhage. Patients with cerebral hemorrhage can present with a variety of signs and symptoms, depending on the blood vessels involved in the lesion. In the case of massive brain hemorrhage, the signs and symptoms are generally more severe, and most patients can have impaired consciousness, including drowsiness, lethargy and coma, and generally have cerebral edema and increased intracranial pressure, and most patients may have certain sequelae, with a high rate of disability and death. Most patients can be clinically cured with aggressive and correct treatment if they have a small amount of bleeding.
