title: Declining prevalence of hydrocephalus.
abstract: Data from the Glasgow Register of Congenital Anomalies were used to compare the recent prevalence of primary hydrocephalus with that of anencephalus and spina bifida. Between 1974 and 1985, the prevalence rates of all three conditions declined significantly and virtually in parallel, a phenomenon suggestive of a common aetiology.
