Abstract

Cognitive deficits are a core feature of psychotic disorders. Both in adult and adolescent populations, studies have shown that patients with psychosis have poorer cognitive functioning than controls. The cognitive domains that seem to be affected are mainly attention, working memory, learning and memory, and executive function. However, with regard to the trajectory of cognitive function throughout the illness, there is still a dearth of prospective data in patients who develop psychosis during adolescence. In this article, neuropsychological functioning was assessed in a sample of 24 first episodes of early onset psychosis (EOP) and 29 healthy adolescents at baseline and after a two-year follow-up. Patients with EOP showed lower scores than controls in overall cognitive functioning and in all specific domains assessed (attention, working memory, executive function, and learning and memory) both at baseline and the two-year follow-up. When changes in cognitive functioning over two years were assessed, patients and controls showed significant improvement in almost all cognitive domains. However, this improvement disappeared in the patient group after controlling for improvement in symptomatology. Our findings support a neurodevelopmental pathological process in this sample of adolescents with psychosis.
