IN THE absence of specific neurophysiological correlates of emotional illness, it has been difficult to delineate syndromes of cerebral dysfunction which might be related to psychiatric disorders. The armamentarium of the investigator in this area is usually limited to clinical and psychological-test examination of the patient, a variety of neuropsychological tests such as those devised by Halstead and Reitan,1,2 critical flicker fusion, the electroencephalogram (EEG), psychophysiological tests such as those devised by Lacey and Lacey,3,4 and response to psychotropic or anticonvulsant agents.5 Family, developmental, and social histories have received relatively little attention although more recent work has been done in these areas relative to cerebral function.
Although clinical correlates of the EEG have been difficult to elucidate in the past, more recent work has indicated that the EEG may be useful as a predictor of developmental and clinical characteristics
