Cerebral hemorrhage is non-traumatic bleeding within the brain parenchyma, and its most common cause is hypertensive disorders. The basal ganglia region is the most common site of cerebral hemorrhage, with relatively few hemorrhages in the lobes, cerebellum, and brainstem. There are abundant motor and sensory nerve fibers passing through the basal ganglia, and a hemorrhage of about 5 ml may cause more serious hemiparesis, but usually the patient will not have consciousness disorder. 5 ml of hemorrhage in the basal ganglia area can be absorbed after treatment in about 1 week to 10 days, and the patient can be discharged from the hospital with improvement. The nerve fibers in the lobes of the brain are more sparsely dispersed, and a 5ml hemorrhage may not cause any clinical discomfort or only a mild headache, and the patient may be discharged from the hospital within 2 weeks. A 5ml hemorrhage in the cerebellum and brainstem is more serious. The brainstem is the center of the respiratory and cardiac system, and 5 ml of bleeding can have serious consequences, and the patient is likely to die. The cerebellum is closer to the brainstem, and if the 5ml hemorrhage is treated in time to avoid compression of the brainstem by cerebral edema, the patient usually recovers better, and can recover after about 2 weeks of treatment.
