Event-related potentials in schizotypal personality disorder and schizophrenia

Abstract

The article presents an analysis of event-related potentials in Go/NoGo test from patients with schizophrenia and schizotypal personality disorder relative to healthy subjects. Identified differences in the group of patients with schizophrenia are consistent with previous studies and indicate a violation of the processes associated with different stages of visual information processing and executive functions. Special features of the brain activity from patients with schizotypal personality disorder were significantly less pronounced, and, presumably, pointed on the changes in the processes of attention redistribution and action monitoring. The results agree well with the clinical symptoms of schizophrenia and schizotypal personality disorder that allows us to consider this technique as a possible additional diagnostic criterion of these disorders.
