Electroconvulsive therapy for severe depression, psychosis and chorea in a patient with Huntington's disease: case report and review of the literature.

ABSTRACT

AIMS AND METHOD: The psychiatric manifestations of Huntington's disease are myriad and difficult to control. The use of electroconvulsive therapy (ECT) is not commonly considered for this condition. We describe a patient with severe depression, psychomotor retardation, delusions and weight loss who responded to ECT with good control of her symptoms. RESULTS: Both our case and the literature appear to confirm the efficacy of ECT in the treatment of depression in Huntington's disease and suggest that other psychiatric manifestations of Huntington's are also responsive. CLINICAL IMPLICATIONS ECT is an effective and safe treatment that should be considered earlier in the course of the disease in cases that show limited response to pharmacological therapy. It should also be considered as an adjunct to medical therapy that may simplify polypharmacy and allow better control in patients with debilitating psychiatric manifestations of the disease. There is limited and conflicting evidence for its efficacy in chorea.
