title: EEG and evoked potentials in the psychoses.
abstract: EEG and evoked potential (ER) findings in schizophrenic and affective psychoses were selectively reviewed. Both groups of psychoses appear to differ from normal in a number of EEG and ER characteristics; however, diagnostic specificity was suggested by relatively few findings. More encouraging result with respect to specificity have been obtained by subtyping the psychotic groups, e.g., process versus reactive schizophrenic, unipolar versus bipolar depression. Methodologic issues and directions for future research were discussed.
