ELECTROENCEPHALOGRAPHY IN SCHIZOPHRENIC-PATIENTS - COMPARISON BETWEENNEUROLEPTIC-NAIVE STATE AND AFTER TREATMENT

Electroencephalography of 12 schizophrenic patients was recorded in a neuroleptic-naive state and after 6.2 +/- 1.1 months of treatment, whe n they were on medication and in partial remission. Compared with age- and sex-matched controls, the neuroleptic-naive schizophrenics had le ss alpha 2 power. In the medicated state, alpha 2 power and slew-wave power were reduced as compared with the neuroleptic-naive state. The r eduction in alpha 2 power may occur from the early stage of the diseas e and progress even though the patients are medicated and clinically i mproved.
