The causes of cerebral hemorrhage are as follows: 1, hypertension: elevated blood pressure damages blood vessels and leads to vascular sclerosis, while elevated blood pressure can easily break through blood vessels leading to hemorrhage; 2, abnormal blood vessel development: common are arteriovenous malformations and aneurysms inside the cerebral vessels, and aneurysms are prone to rupture, which can easily lead to hemorrhage; 3, blood system problems: blood system problems that are prone to hemorrhage can lead to cerebral hemorrhage, common are hemophilia, leukemia, and some blood system diseases with reduced platelets.
