Long-term prognosis for children with shunted hydrocephalus.

We reviewed the previous medical history and the social status of all patients of Oulu University Central Hospital who had had in the age range 16-26 years shunted hydrocephalus (HC) during childhood. Of 42 patients selected 7 had died and another 5 had been institutionalized for severe mental handicap. Shunts had been changed a total of 103 times in 29 patients still living. The most common reason for a reoperation was blockage. Half of the patients re-examined showed neurological abnormalities or epilepsy. Both the verbal and the nonverbal IQ of the patients remained weak to average. Even though the patients' medical prognosis was fair, their social maturation did not keep up with their physical abilities. One-third were receiving or had received vocational training, but only a few were working. Up to one-quarter of the patients with shunted HC were at home without any meaningful work activities.
