1. It depends on where the bleeding site is. In the cerebral hemisphere bleeding, a small amount is awake, and a large amount is coma. In cerebellar hemorrhage, there is mostly no coma. 2, depends on the amount of bleeding. In the cerebral hemisphere, if the bleeding volume is less than 20ml, the patient is often not in coma; if the bleeding volume is about 30ml, the patient may have impaired consciousness, such as shallow coma, lethargy, drowsiness, etc., and can be awake after treatment for about half a month. If the bleeding volume is greater than 40ml, the patient often has coma, and most of them are awake in about half a month without dilated pupils on one side. If there is a dilated pupil on one side, the coma lasts a little longer. In cerebellar hemisphere hemorrhage, there is often no impairment of consciousness, but there is the possibility of sudden respiratory arrest at any time, which is related to the damage of the medulla oblongata respiratory center. 3. It depends on the age, physical strength and severity of complications.
