Abstract

This study served as a pilot study of cingulate gyrus surface areas and their relation to intelligence in individuals with hydrocephalus. Surface areas of the corpus callosum and cingulate gyrus regions were compared between individuals with early hydrocephalus (n = 9) and controls (n = 7). Subsequently, the surface areas were correlated with full-scale intelligence scores and the verbal and nonverbal discrepancy scores. Corpus collosum surface areas were significantly smaller in participants with hydrocephalus. These areas also robustly correlated with full-scale intelligence scores. Although the cingulate gyrus did not differ significantly between the groups, the cingulate gyrus regions were increasingly divergent the more posterior the region. Additionally, the caudal anterior and the posterior cingulate gyrus regions had only moderate positive correlations with full-scale intelligence scores. Although the participants with hydrocephalus had a significantly lower mean performance IQ compared to verbal IQ, the discrepancy scores did not correlate significantly with any of the regions of interest.
