Approximately 60 percent of people survive ruptured brain aneurysms, explains Brain Aneurysm Foundation. About 65 percent of ruptured brain aneurysm survivors suffer subsequent neurological issues. However, about 20 percent of survivors experience no long-term disabilities, explains American Association of Neurological Surgeons.
The person's age and general health, as well as the size and location of the brain aneurysm, impact survival rates and long-term prognosis, explains MedicineNet.
Younger people generally fare better, though 50 percent of ruptured aneurysm deaths occur in people younger than 50, according to Brain Aneurysm Foundation. The type of aneurysm also matters. Aneurysmal subarachnoid hemorrhages cause uncontrollable bleeding that cannot be corrected with surgery.
In the two weeks after the initial rupture, about 20 percent of patients experience repeat hemorrhaging, notes American Association of Neurological Surgeons. Up to 15 percent of all brain aneurysm survivors have another secondary aneurysm, according to Brain Aneurysm Foundation.
