The risk period for brain hemorrhage usually takes about two weeks to pass because of the period of cerebral edema and related complications that need to be experienced after a brain hemorrhage. Some rebleeding may also occur, mostly within 72 hours after the initial occurrence of a brain hemorrhage. Cerebral edema is good for 3-5 days and starts to subside in about a week, and complications are good for less than two weeks. Therefore, the risk period generally requires at least two weeks to elapse and at least three weeks to elapse for complete relative stability. Once a brain hemorrhage has occurred, close attention should be paid to the changes in the condition, and depending on the head CT, early surgical or conservative treatment should be taken to control the symptoms of increased intracranial pressure brought about by the brain hemorrhage. After the intracranial pressure is effectively controlled, the patient’s condition can gradually stabilize.
