| Sumario: | Hirotsugu Kawashima,1 Yuko Kobayashi,1 Taro Suwa,2 Toshiya Murai,2 Ryuichi Yoshioka1 1Department of Psychiatry, Toyooka Hospital, Toyooka, Hyogo, Japan; 2Department of Neuropsychiatry, Graduate School of Medicine, Kyoto University, Kyoto, Japan Abstract: Inducing adequate therapeutic seizures during electroconvulsive therapy (ECT) is sometimes difficult due to a high seizure threshold, even at the maximum stimulus charge. Previous studies have demonstrated that seizure threshold is lower in patients treated with right unilateral ultrabrief pulse (RUL-UBP) ECT than in those treated with bilateral or brief pulse (BL-BP) ECT. Therefore, switching to RUL-UBP ECT may be beneficial for patients in whom seizure induction is difficult with conventional ECT. In the present report, we discuss the case of a patient suffering from catatonic schizophrenia in whom BL-BP ECT failed to induce seizures at the maximum charge. However, RUL-UBP ECT successfully elicited therapeutic seizures and enabled the patient to achieve complete remission. This case illustrates that, along with other augmentation strategies, RUL-UBP ECT represents an alternative for seizure induction in clinical practice.
