Electroencephalography of 12 schizophrenic patients was recorded in a neuroleptic-naive state and after 6.2 ± 1.1 months of treatment, when they were on medication and in partial remission. Compared with age- and sex-matched controls, the neuroleptic-naive schizophrenics had less alpha 2 power. In the medicated state, alpha 2 power and slow-wave power were reduced as compared with the neuroleptic-naive state. The reduction in alpha 2 power may occur from the early stage of the disease and progress even though the patients are medicated and clinically improved.
