EEG correlates of a mental arithmetic task in patients with first episode schizophrenia and schizoaffective disorder

Popis výsledku v původním jazyce

Objective: To evaluate the spectral power of the cortical bands in patients with first episode schizophrenia and schizoaffective disorder at rest and during the performance of a mental arithmetic task. Methods: We analyzed EEG spectral power (SP) in theresting state and subsequently while counting down from 200 in steps of 7, in 32 first episode schizophrenia patients (SZ), 32 patients with first episode schizoaffective disorder (SA) and healthy controls (HC, n = 40). Behavioral parameters such as accuracy and counting speed were also evaluated. Results: Both SZ and SA patients were slower in counting than HC, no difference was obtained in the accuracy and counting speed in the patient groups. In the resting state patients showed elevated midline theta power, off-midline anterior beta 2 power and decreased central/posterior alpha power. The SA group occupied an intermediate position between the schizophrenia patients and controls. In task performance patients lacked a typical increase
