Tardive Dyskinesia: Subtle Symptoms and the Huge Impact of Early Recognition and Intervention

Overview

Clinicians should screen regularly for signs and symptoms of tardive dyskinesia and educate patients and caregivers on what to look for and report, leading to earlier intervention and better quality of life.

Learning Objectives

After completing the educational activities, learners will be able to: 

  • Conduct regular screenings for signs of TD during follow-up visits after treatment initiation
  • Educate patients and family members about TD, including how to recognize the symptoms
  • Use best practices that are based on evidence and expert consensus to manage TD
  • Select FDA‐approved medication to treat TD

Target Audience

Psychiatrists and psychiatric nurse practitioners and physician assistants; primary care clinicians

Program Description

Tardive dyskinesia (TD) is a medication-induced movement disorder that can last decades and is often a permanent condition. TD affects 25% to 30% of patients taking antipsychotic medications and 26% to 67% of patients on long-term dopamine antagonists. Clinicians should regularly screen patients with a history of neuroleptic use for signs and symptoms of TD, such as dystonia, buccolingual stereotypy, chorea, akathisia, tics, or other abnormal involuntary movements, particularly if they appear within 1 to 2 years of continuous exposure to the medication. However, TD can appear earlier, especially in the elderly population. A differential diagnosis requires excluding other involuntary movements such as habits, mannerisms, paroxysmal dyskinesias, and benign hereditary chorea and other disorders, including myoclonus, dystonia, tics, and chorea. Structured instruments for TD assessment include the Abnormal Involuntary Movement Scale (AIMS) and the Dyskinesia Identification System: Condensed User Scale (DISCUS). These screenings should be administered at the time of new onset or exacerbation of an existing movement disorder as well as every 6 months to patients at high risk of developing TD and every 12 months to other patients. Educating patients and families about the risk of TD associated with chronic neuroleptic use as well as signs and symptoms of the disorder are an important piece in earlier invention of this distressing disorder, improving quality of life and leading to better patient outcomes.

Statement of Need and Purpose

Clinicians who treat patients with dopamine receptor blocking agents—such as antipsychotics for schizophrenia, bipolar disorder, or major depression—need to consider the risk for tardive dyskinesia (TD), educate patients and their families about the risk and early signs, recognize early symptoms, and provide treatment. A substantial proportion of patients with TD do not have a timely diagnosis, meaning that treatment is delayed and the chance for a poor outcome is increased. Because some clinicians underestimate the risk of TD, especially with newer antipsychotics, they do not advise patients about the risk of TD, educate them about early signs to watch for and report, or conduct routine screenings.  Effective medications for TD should be implemented as appropriate, incorporating data on the functional impact of TD on the patient. Clinicians need education on evidence‐based, expert‐consensus care for TD.
