title: Use of modified electroconvulsive therapy in a case of polymyositis presenting with delusion of nihilism of proxy (Odysseus syndrome).
abstract: We present a case of psychotic depression with polymyositis presenting with the distinct phenomenon of nihilism by proxy, which was treated with electroconvulsive therapy (ECT). A female patient with polymyositis was initially treated with pharmacotherapy. After initial response, there was deterioration in her mental state and hence, after careful consideration, neurological, and anaesthetic consultations, modified ECT was given with close monitoring. The mental state of the patient improved with a course of ECT, which proceeded without any complications. Her depressive symptoms including the delusion of nihilism by proxy responded to ECT. To the best of our knowledge, the use of ECT has not been reported in a case of polymyositis before, and this case shows that modified ECT can be given successfully in patients with polymyositis.
