It is possible to wake up after a brain hemorrhage if there is a disorder of consciousness, depending on the amount of bleeding, the location of the bleeding and the degree of disorder of consciousness of the patient. If the brain hemorrhage is large, with about 30 ml, and located in the basal ganglia area, it may cause the patient to have impaired consciousness, and the degree of impaired consciousness is not severe, with drowsiness and lethargy predominating. After treatment to reduce brain edema and slow absorption of the hemorrhage, most patients’ consciousness can return to normal. If the hemorrhage is above 50 ml, the patient often goes directly into coma, and even after treatment, the patient may not be fully conscious due to excessive brain tissue destruction. If the hemorrhage is in a specific area, such as the brainstem, even a small hemorrhage of 2-3 ml can cause the patient to enter a coma with a very poor prognosis and a low likelihood of waking up.
