Tardive dyskinesia (TD) is a serious and disabling movement disorder; it impairs social function and quality of life and increases the mortality rate. TD is usually induced by the use of antipsychotic drugs; however, the underlying mechanism remains unclear. Pharmacotherapy of TD includes cholinergic drugs, benzo
A 69-year-old woman who was diagnosed as having schizophrenia 16 years ago developed severe TD after 6-mo prescription of risperidone oral solution. Her TD symptoms did not resolve despite various treatments, such as GBE, vitamin E, trihexyphenidyl, promethazine, benzodiazepines, and switching to quetiapine and olanzapine. After admission, she was given deutetrabenazine 6 mg bid. Her buccal tremor was slightly resolved 3 d later; however, her tongue remained protruded and could not be retracted. Quetiapine was switched to clozapine on day 4, and the buccal tremor remarkably resolved, and the tongue could be retracted into the mouth from day 6 onward. After three sessions of MECT, the buccal tremor resolved further. Since then, she has been able to take a semifluid diet, and her quality of life improved remarkably during 6 mo of follow-up.
TD is a serious condition which could be caused by antipsychotic medications; however, the best strategy against TD is prevention and monitoring during using antipsychotics. For patients with TD caused by antipsychotic medication use, multiple measures should be considered like switching to clozapine, adjunction with deutetrabenazine, or even MECT.
Core Tip: Tardive dyskinesia (TD) is a serious and disabling movement disorder, and its pathogenesis remains unclear. This report describes the treatment of TD caused by risperidone in a schizophrenia patient, which could not be improved by switching to the other second-generation antipsychotics like quetiapine and olanzapine, neither by adjunction with medications like benzodiazepines, ginkgo biloba extract, or antioxidants. Her TD symptoms were relieved remarkably after multiple measures like switching to clozapine, adjunction with deutetrabenazine, and modified electroconvulsive therapy. Multiple measures are therefore recommended for TD treatment.
