Diagnostic and Treatment Fundamentals for Tardive Dyskinesia

Can you recognize risk factors for tardive dyskinesia? Are you familiar with diagnostic criteria? Do you regularly assess patients for the condition? Are you knowledgeable about using new medications for TD? Experts share best practices for the assessment and treatment of TD.

Abstract

Tardive dyskinesia (TD) consists of involuntary movements of the tongue, lips, face, trunk, and extremities that occur in patients treated long-term with dopamine antagonist medications. TD can be associated with significant functional impairment and be socially stigmatizing. TD, once established, has proved to be often irreversible and remains a significant treatment issue. An accurate and early diagnosis of TD is crucial because the risk of permanence increases over time. Clinicians should be educated on which patients are most at risk for TD and conduct assessments through clinical examination or through the use of a structured evaluative tool such as the Abnormal Involuntary Movement Scale (AIMS). Patients and caregivers need to be educated about the risks of and alternatives to antipsychotic medication and early signs of TD. New treatment approaches to persistent TD are available and approved by the US Food and Drug Administration: the vesicular monoamine transporter-2 (VMAT2) inhibitors, deutetrabenazine and valbenazine. When treatment is initiated, a baseline assessment should be obtained by clinicians using the AIMS and follow-up assessments should be done on a regular basis. In this educational activity, Drs Correll and Citrome offer a review of the diagnostic and treatment fundamentals for TD.

Release, Review, and Expiration Dates

This CME activity was published in September 2021 and is eligible for AMA PRA Category 1 Credit™ through September 30, 2023. The latest review of this material was August 2021.

Statement of Need and Purpose

TD must be detected early to minimize the risk of the movements becoming permanent. But many clinicians are unable to identify risk factors for this condition, are unfamiliar with diagnostic criteria, and do not regularly assess patients for TD. Clinicians, therefore, need education on the risk factors that should alert them to monitor certain patients especially closely for TD and strategies to assess all patients being treated with dopamine-blocking agents and provide an accurate diagnosis. In addition, while treatment for TD is available, with evidence-based recommendations and research on long-term safety and efficacy, clinicians may be slow to implement treatment strategies due to underestimation of the social and occupational impact that TD has on patients’ lives and uncertainty about what to do.

Disclosure of Off-Label Usage

Dr Correll has determined that, to the best of his knowledge, Vitamin E, Vitamin B6, Ginkgo Biloba, eicosapentaenoic acid (fish oil), melatonin, clonazepam, amantadine, donepezil, Branched Chain Aminoacids (BCAA), reserpine and tetrabenazine, are not approved by the US Food and Drug Administration for the treatment of tardive dyskinesia.

Review Process

The faculty members agreed to provide a balanced and evidence-based presentation and discussed the topics and CME objectives during the planning sessions. The faculty’s submitted content was validated by CME Institute staff, and the activity was evaluated for accuracy, use of evidence, and fair balance by the Chair and a peer reviewer who is without conflict of interest.
