| Outline of Final Research Achievements |
We performed a pharmaco-EEG study of antipsychotics in patients with schizophrenia by qEEG analyses. Resting EEG was recorded before and four weeks after treatment with aripiprazole (APZ) in four drug naive patients with schizophrenia. EEG microstates were computed in 2-20Hz in two cases, and compared to microstates which were obtained from controls. Whole cortex electric neuronal activity distribution, and intracortical physiological lagged connectivity between 11 ROIs, were computed in seven frequency bands, using the sLORETA software, and compared to the normative BRL-sLORETA database in four cases.
Deviations at baseline of certain microstate of one case and cortical activity distribution of three cases tended towards normal values after treatment. In two cases, baseline deviant functional connectivity of delta activity normalized after treatment.
APZ induced changes towards normal in several values. This evidence may give partial support for the effectiveness of the medication.
