Use of electroconvulsive therapy (ECT) has been infrequently described in patients with systemic lupus erythematosus and is most commonly used in patients with catatonia. In this report, we describe the use of ECT in a young adolescent girl who had bipolar affective disorder associated with systemic lupus erythematosus and was treated with ECT for the depressive episode. The patient achieved remission with a course of 6 ECT treatments.
