Tardive dyskinesia and dystonia are intractable extrapyramidal symptoms caused by the blockade of dopamine receptors by antipsychotic drugs. In addition to the reduction or discontinuation of the causative drug, valbenazine for tardive dyskinesia and botulinum toxin for tardive dystonia have been reported to be effective. However, their efficacy has not been fully demonstrated. In this study, we report the case of a female patient with bipolar disorder, valbenazine-resistant tardive dystonia, and tardive dyskinesia who achieved improvement in extrapyramidal symptoms with electroconvulsive therapy. Additionally, we conducted a narrative literature review on the safety and efficacy of electroconvulsive therapy for tardive dyskinesia and dystonia.
