What is that supposed to mean? I have not read anywhere that he is expected to make anything less than a full recovery.
Surgical procedures are available for dealing with the aneurysm, but the risk from surgery may be at least as great as that from the aneurysm itself. The prognosis for people who experience a ruptured aneurysm is not good. About 15 to 25 percent of those who experience a rupture do not survive the event. An additional 25 to 50 percent survive the immediate episode, but die of complications caused by bleeding in the brain. Of those who do survive, about 15 to 50 percent suffer permanent brain damage or physical disability.
