Abstract: A 24-year-old man experiencing comorbid body dysmorphic disorder since age 16 years, complicated in recent months by a major depressive episode with psychotic features, showed resistance to various drug and psychotherapy combinations. We suggested electroconvulsive therapy (ECT) to overcome treatment resistance. After 1 ECT cycle, mood and anxiety symptoms improved significantly, delusional interpretations and ideas of reference subsided, and dysmorphophobic symptoms improved as well. Six months later, the patient was doing well with a mood stabilizer/antipsychotic combination. Electroconvulsive therapy may improve symptoms of comorbid body dysmorphic disorder along with mood improvement in treatment-resistant depressive disorder.
