title: EEG abnormalities in bipolar affective disorder.
abstract: Forty-six patients with bipolar illness were evaluated with scalp-recorded electroencephalograms. Familial pattern of psychopathology was evaluated between groups with clinically normal and abnormal EEG tracings. Those with abnormal EEGs were noted to have a significantly negative family history of affective disorder when compared to the EEG normal group. These results may support the concept of some patients with mania having an acquired illness which occurs independent from its genetic loading.
