The recovery period after a bleeding aneurysm in the brain has to be treated according to the specific situation at the time. Generally speaking, the recovery period after aneurysm hemorrhage will be around 1 month to 1.5 months, because there are 3 most dangerous periods to go through, and after going through these 3 most dangerous periods, the rehabilitation and functional exercise will be left in the later stage. 1. Dangerous period, that is, 3 days after aneurysm hemorrhage in the brain, this is the most dangerous period, and the main concern is the rupture of the hemorrhage again, after going through this period, basically there will be very little rupture and hemorrhage again in the later stage. 2. After passing through this period, basically it is rare to rupture and bleed again in the later stage.2, the high incidence of intracranial infection, generally speaking, this will appear about 7-10 days after the operation, if the temperature rises in the early stage, it is necessary to carry out the lumbar puncture test in a timely manner, to make it clear that the condition changes, and apply antibiotics at an early stage to prevent intracranial infections.3, cerebral vasospasm and the period of brain swelling, the peak is in the 14-day period, if it passes through this period, the peak is in the 14-day period. Around this period, if through this period, the late neurological function generally will not further deteriorate, leaving a period of slow recovery function recovery.
