Tardive dyskinesia impact and prevalence
Disruptive, distressing, stigmatizing—tardive dyskinesia (TD) has been shown to be an added burden for patients already managing an underlying mental illness1,2,a,b
Disruptivea,b
Uncontrolled movements can impact patients’ ability to perform daily activities1,2
Distressinga,b
Abnormal and uncontrolled movements may cause embarrassment in public1-3
Stigmatizinga,b
TD symptoms may exacerbate the stigma associated with existing mental illness1-4
a | Includes results based on a survey of patients diagnosed with TD (n=127), who were asked, “How would you rate your current ability to undertake your regular activities?” Responses based on a 3-point scale selection of “Low,” “Medium,” or “High”; “What would you say about your general well-being in each of the following areas?” Responses based on 7-point Likert scale (range of 1 [“Not good at all”] to 7 [“Excellent”]); “Tardive dyskinesia may impact you in different ways. To what extent has tardive dyskinesia impacted you in each of the following areas?” Responses based on 7-point Likert scale (range of 1 [“Not at all impacted”] to 7 [“Extremely impacted”]).1 |
b | Includes results based on a survey of psychiatric patients with a clinician-confirmed diagnosis of TD or absence of TD. Health-related quality of life was assessed by: SF-12 Health Survey, Version 2 (SF-12v2), Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form (Q-LES-Q-SF), Social Withdrawal subscale of the Internalized Stigma of Mental Illness Scale (SW-ISMI), and 2 questions on movement disorders.2 |
Between 7.2% and 30% of patients on antipsychotics had tardive dyskinesia according to a 2017 meta-analysis of 41 studies5:
30%
of patients on first-generation antipsychotics
20.7%
of patients on second-generation antipsychotics (with unspecified first-generation antipsychotic use)
7.2%
of patients on second-generation antipsychotics with no prior history of first-generation antipsychotics
While anyone with exposure to antipsychotics can develop TD,5 the following may be associated with increased risk:
Patient risk factors for TD
- Aged 50 or older6
- Substance use disorder7
- Being postmenopausal8
- Diagnosis of mood disorder9
Treatment risk factors for TD
- Cumulative exposure to antipsychotics7
- Treatment with anticholinergics7
- History of acute extrapyramidal symptoms7
- Potency of antipsychotics10

Question 1 of 5
TRUE OR FALSE:
Tardive dyskinesia (TD) is a clinically distinct, drug-induced movement disorder and is associated with prolonged exposure to dopamine receptor blocking agents (DRBAs), including antipsychotics.
THE CORRECT RESPONSE IS TRUE.
Tardive dyskinesia is distinct from acute extrapyramidal symptoms, such as drug-induced parkinsonism.1,2
Prolonged exposure to DRBAs, including antipsychotics, is believed to cause hypersensitivity in postsynaptic dopamine D2 receptors, one of the areas of the brain that controls motor function.3,4
ASSESSMENT TIP
TD doesn’t just present in the face and mouth—involuntary movements may impact upper and lower limbs, the neck, and trunk. A comprehensive full body assessment can help you identify involuntary movements.5,6

Question 2 of 5
TRUE OR FALSE:
In a 2017 web-based survey, >50% of all patients diagnosed with tardive dyskinesia (TD), regardless of disease severity, reported that they experienced emotional, social, and psychological impact.
THE CORRECT RESPONSE IS TRUE.
All severities of tardive dyskinesia can negatively impact a patient’s well-being, not just severe TD.1
In a 2017 survey, >50% of patients with TDa who self-identified as mild to severe (n=127) reported that TD had a meaningful emotional, social, and psychological impact.1,b,c
ASSESSMENT TIP
The involuntary and uncontrollable movements from tardive dyskinesia may not only impact your patients physically, but also emotionally.1
When assessing the signs of tardive dyskinesia, ask about how it is affecting their everyday lives.

a | Self-reported as diagnosed by a physician. |
b | Question from research: Tardive dyskinesia may impact you in many different ways. To what extent has tardive dyskinesia impacted you in each of the following areas? Responses were based on a 7-point Likert scale (ranged 1 [“Not at all impacted”] to 7 [“Extremely impacted”]). Results shown include responses of ≥6. |
c | Patients self-identified as having mild, moderate, or severe TD. |
Patient survey design1
The blinded online survey was completed by patients between April 26 and November 20, 2017. There were 2 versions of the survey:
- Sample A, for antipsychotic patients (n=2419)
- Sample B, for TD-diagnosed patients (n=127) and symptomatic, undiagnosed patients (n=44)

Question 3 of 5
TRUE OR FALSE:
Prolonged exposure to any antipsychotic, whether first or second generation, is a definitive risk factor for tardive dyskinesia (TD).
THE CORRECT RESPONSE IS TRUE.
Despite common misconceptions, prolonged use of second-generation antipsychotics is still associated with TD.
In fact, between 7.2% and 30% of patients on antipsychotics had tardive dyskinesia according to a 2017 meta-analysis of 41 studies.1
ASSESSMENT TIP
All patients exposed to antipsychotic medication should be monitored for signs of tardive dyskinesia at every clinical encounter—not just those taking first-generation antipsychotics.2

Question 4 of 5
TRUE OR FALSE:
Tardive dyskinesia (TD) will not persist following withdrawal of antipsychotics.
THE CORRECT RESPONSE IS FALSE.
TD may persist, and even worsen, despite reduction in dose or discontinuation of antipsychotics.1
According to the 2013 American Academy of Neurology guidelines, there is a lack of clear evidence to support or refute withdrawing or switching antipsychotics to treat TD. And changing a patient’s antipsychotic regimen may destabilize the underlying psychiatric condition.2
ASSESSMENT TIP
While anyone with exposure to antipsychotics can develop tardive dyskinesia, the following may be associated with increased risk: aged 50 and older, substance abuse, being postmenopausal, diagnosis of mood disorder, history of acute extrapyramidal symptoms (EPS), and potency of antipsychotics.3-8

SCREENING
The American Psychiatric Association (APA) recommends that all patients taking antipsychotics be monitored for tardive dyskinesia (TD) every…
THE CORRECT RESPONSE IS EVERY VISIT.
Regularly monitoring and screening for TD is important to identify movements, minimize worsening, and institute clinically indicated treatment.1
The 2020 APA guidelines state that the clinical assessment of antipsychotic-induced movement disorders, including TD, should be conducted at baseline (prior to starting or changing antipsychotic treatment) and at every follow-up visit for all patients taking antipsychotics, regardless of their risk.1
For patients with the presence of any abnormal movements, the guidelines recommend assessment with a structured instrument, such as the AIMS or DISCUS, at baseline and at a minimum of every 6 months in high-risk patients, and every 12 months in other patients.1
AIMS, Abnormal Involuntary Movement Scale; DISCUS, Dyskinesia Identification System Condensed User Scale.
ASSESSMENT TIP
When screening for TD, be sure to look for: history and current use of DRBAs (including first- and second-generation antipsychotics); choreiform (rapid and jerky) movements of the eyes, lips, jaw, tongue, and limbs; and athetoid (slow, sinuous, or writhing) movements of the hands, feet, and trunk.2-4
