title: Cognitive functioning in female patients with 21-hydroxylase deficiency.
abstract: The cognitive functioning of 27 female patients with congenital adrenal hyperplasia (CAH) (aged 11-41 yrs) and 13 of their healthy sisters (13-31 yrs) was compared using short versions of age-appropriate Wechsler scales. In contrast to other studies, neither a higher than average IQ level for CAH patients (mean: 99.0) nor for their sisters (97.7) was found. Unexpectedly, and in contrast to other reports, the subgroup of salt-wasting (SW) patients>16 yrs (N=6; mean score: 111.5) differed from their sisters as well as from simple-virilizing (SV) patients in "full IQ" (p<0.05) and subtest scorings for "Information", "Similarities", and "Picture Completion" (p<0.05-<0.10). SW patients displayed "more masculine" behaviour (vs. SV patients and sisters) which, in turn, was related to differential prenatal hormonal influences. No clear-cut relationships between IQ/cognitive (subtest) findings and gender-role behaviour were found.
