EEGs in Chronic Schizophrenia

Abnormalities in the EEG of schizophrenics were first described by Lemere (1936) who found schizophrenic EEGs had poor alpha waves. Earlier workers were more interested in frequency abnormalities and Davis (1941) found, from study of the frequencies, the more unstable the EEG in schizophrenia the more unstable the behaviour. This concept is well established and has been confirmed by Brazier (1962) and other workers. However, the study of the different frequencies has shed little or no light upon the aetiology of schizophrenia.
