Three cases of elderly depressed patients with symptoms of tardive dyskinesia (TD) subsequently treated with electroconvulsive therapy (ECT) are presented. These cases are discussed in relation to several cases reported in the literature of ECT and TD. The possibility of improvement in symptoms of TD in certain patients is discussed.

    ABSTRACT: Background Tardive dystonia and dyskinesia are potentially irreversible neurological syndromes. Successful electroconvulsive treatment (ECT) has been reported by multiple sources; however, the existing retrospective reviews and open prospective trials provide little information on the response rate. Methods Eighteen consecutive patients with tardive dystonia or dyskinesia received a standard course of ECT to treat abnormal movement. The severity of the tardive dystonia and dyskinesia was evaluated using the Abnormal Involuntary Movement Scale (AIMS) before and after the course of ECT. The patients who displayed a greater than 50% improvement in the AIMS score were classified as the responders. Results The mean AIMS score decreased from 19.1±4.7 to 9.6±4.2. There were seven responders among the 18 patients, which yielded a 39% response rate. Conclusion ECT has a moderate but significant effect on tardive dystonia and dyskinesia.

    ABSTRACT: Early case reports note marked improvements in the signs of Parkinson's disease (PD) in several patients with coexisting psychiatric disorders after treatment with electroconvulsive therapy (ECT). Studies since 1959 reveal improvement of parkinsonism in over half of PD patients receiving ECT, regardless of the presence or absence of psychiatric comorbidity. Drug-induced parkinsonism, tardive dystonia, and tardive dyskinesia have also been shown to improve with ECT administration; tic syndromes have achieved mixed results. In animals, ECT enhances dopamine-mediated effects and increases GABA concentrations in the CNS. Optimal parameters relevant to the antiparkinsonism effects of ECT require further study.
