Case report of electroconvulsive therapy in a patient with Parkinson disease concomitant with deep brain stimulation.

We report on a 56-year-old woman with Parkinson disease who had previously been implanted with bilateral deep brain stimulation (DBS). She was hospitalized after a 2-year course of severe depression with psychotic features and physical as well as mental decline. She underwent 2 rounds of successful electroconvulsive therapy (ECT), improving both her physical and mental health without any adverse effects to the patient or the DBS. This is a fourth reported case of ECT being successfully and safely administered in a patient implanted with DBS. This is the first case report of bitemporal ECT in a patient with bilateral DBS. It is also the first case report using the MECTA device and the first case report of a successful and safe second course of ECT after relapse of this patient's depression.
