Hemorrhagic strokes have a 50% mortality rate. If caught early, they lot sometimes be treated by repairing intracerebral aneurysms (Tabers 2069). The sincerity o f the stroke depends on how long blood flow ! was interrupted, the field of operations field of the brain affected, and the extent of permanent neurological damage. For example, city block of the honorable middle cerebral artery would affect the frontlet and parietal lobes.
