Skull changes and intellectual status in hydrocephalic children following CSF shunting.

A total of 76 shunt-treated hydrocephalic children were examined at least once between two and 12-years after surgery to determine what skull changes had occurred and to assess the children's intellectual status. The high incidence of skull changes in shunt-treated, non-tumoral, hydrocephalic children was confirmed. A strict relationship existed between skull changes and low intracranial pressure. The results indicate that impairment of mental development parallels the degree of skull changes, suggesting a close relationship between impaired mental development and cerebrospinal fluid hypotension.
