[Drug-induced absence status: the significance of EEG in diagnosis and treatment].

Four patients with an absence status induced by drugs, are described. In three patients the use of neuroleptics was the probable cause, in the other indomethacin could be incriminated. As yet an absence status after treatment with these medicaments has not been described. Clinically, the diagnosis was not unequivocal. The EEG gave clear results, rapidly indicating the cause of the patient's clinical condition.
