Abstract
BACKGROUND: Abnormalities of the anterior cingulate cortex (ACC) are frequently implicated in the pathophysiology of psychotic disorders, but whether such changes are apparent before psychosis onset remains unclear. In this study, we characterized prepsychotic ACC abnormalities in a sample of individuals at ultra-high-risk (UHR) for psychosis. METHODS: Participants underwent baseline magnetic resonance imaging and were followed-up over 12-24 months to ascertain diagnostic outcomes. Baseline ACC morphometry was then compared between UHR individuals who developed psychosis (UHR-P; n = 35), those who did not (UHR-NP; n = 35), and healthy control subjects (n = 33). RESULTS: Relative to control s..
