The time to recover from cerebral hemorrhage intelligence depends mainly on the specific cause of the hemorrhage. If the brain hemorrhage intellectual impairment is caused by hydrocephalus after brain hemorrhage, generally after the symptoms of hydrocephalus are improved, the intellectual ability can be gradually recovered, and the time mainly depends on the time of taking measures against hydrocephalus. Second, if the brain hemorrhage intellectual impairment is caused by the brain hemorrhage itself, causing the corresponding neurological damage, the intellectual recovery will be restored within six months. If intelligence is not restored within half a year, the possibility of recovery at a later stage is relatively small, because intellectual impairment is mainly caused by neurological damage, and the golden recovery period of neurological function is within half a year after the hemorrhage. For patients with brain hemorrhage and mental impairment, early treatment such as cognitive function training, hyperbaric oxygen and acupuncture can be used to minimize the degree of mental impairment and improve their symptoms.
