How long it takes to wake up from a brain hemorrhage depends mainly on the location and the amount of brain hemorrhage. If the amount of brain hemorrhage is large, it takes at least three weeks for the patient’s condition to stabilize completely. Within three weeks, the patient may die due to changes in his or her condition. For this type of patients, if they survive, their reawakening should be less likely, and they are mostly considered to exist in a vegetative state of survival at a later stage, that is, they are not able to revive. If the amount of brain hemorrhage is moderate, the patient may wake up within six months after active treatment. If the condition can be effectively controlled, the patient is relatively young and has few underlying diseases, the patient is likely to wake up in about three weeks. If the brain hemorrhage is relatively small, the patient may be admitted to the hospital and may experience a transient coma of consciousness due to a stress reaction, and may generally be awake in about three days.
