title: Decreased maternal age with hydranencephaly.
abstract: We studied parental ages of institutionalized children with hydranencephaly. Mothers under age 20 years and under age 18 years were, respectively, 5 and 10 times as frequent as in the general population, and 3 and 4 times more frequent than for institutionalized control patients. Unwed mothers were also common, but may reflect high rates in younger mothers combined with institutionalization bias. Thus, hydranencephaly appears to show a decreased maternal age effect, similar to that seen with other conditions presumably due to prenatal vascular disruptions.
