The Classification of Psychoses by Quantitative EEG Measures

In a review of EEG abnormalities in mental disorders, Ellingson [1] concluded: “Beyond differentiating the few organic cases which will be found, the EEG is of no value in the differential diagnosis of mental disorders or in personality assessment at the present time...” Reports of a relationship between EEG variables and psychiatric diagnosis or mental state continue to appear, however [2–12]. Ellingson [1] ascribed the major sources of error in earlier studies to such factors as differences in patient populations and difficulties in the classification of subjects by psychopathological criteria alone, variability in the criteria of EEG abnormality, lack of controls, and a lack of statistical evaluation.
