Damaged brain cells cannot be recovered after a brain hemorrhage because brain cells are fragile and can die in 4-6 minutes in the absence of blood and oxygen. Brain hemorrhage is a problem of destruction of brain cells, which cannot be recovered after death. However, after brain hemorrhage occurs, it is important to improve the head CT examination in time and choose the treatment plan according to the amount of bleeding of the patient. If the amount of bleeding is large, the patient needs to be treated by surgical removal of the hematoma. Early removal of the hematoma is mainly to treat the increased intracranial pressure of the patient and prevent the patient from brain herniation, which can reduce the damage of the hematoma to the brain nerves and brain tissue, so it is beneficial to the recovery of the disease. If the amount of bleeding is relatively small, treatment is conservatively carried out in internal medicine to prevent patients from continuing to bleed and to promote the recovery of neurological function through dehydration and lowering of cranial pressure. If the patient is still left with symptoms of limb immobility or other neurological deficits after the acute phase of cerebral hemorrhage, recovery through rehabilitation system is required at a later stage.
