Corpus callosum measurements in girls with Tourette syndrome

Abstract

The objective of this study was to examine whether abnormalities in corpus callosum morphology, previously reported in boys with Tourette syndrome (TS), were also present in girls with this disorder. Among the three groups of girls-TS, TS and attention deficit hyperactivity disorder, and controls-there were no significant differences in the size of the corpus callosum or any of five individual subregions. The findings suggest that abnormalities in corpus callosum morphology in TS are a gender-related phenomenon.
