Abstract
Reductions in the size of the anterior callosum have been described for both first-episode schizophrenia-spectrum psychosis and established schizophrenia, but have not been examined in individuals at ultra-high risk for psychosis (UHR). We compared 100 UHR individuals (27 of whom later developed psychosis) with 38 age-matched control subjects on measures of size and shape of the corpus callosum to determine if changes previously demonstrated in first-episode and established schizophrenia are present in the pre-psychotic phase. Each individual's callosum was extracted from the mid-sagittal slice from T1-weighted magnetic resonance images, and total area, length and curvature of the callosum w..
