Tardive Dyskinesia
A movement disorder involving involuntary, repetitive movements, often of the face and tongue, that can develop after prolonged use of certain antipsychotic medications.
Overview
Tardive dyskinesia is a movement disorder involving involuntary, repetitive movements, most commonly affecting the face, tongue, or limbs, that can develop after prolonged exposure to certain antipsychotic or other dopamine-blocking medications.
Signs and Symptoms
Symptoms can include repetitive movements such as lip-smacking, tongue movements, grimacing, or involuntary limb movements, which can be socially distressing and sometimes persist after the medication is stopped. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.
Causes and Risk Factors
Tardive dyskinesia results from prolonged exposure to medications that block dopamine receptors, most commonly certain antipsychotic medications.
Diagnosis
A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.
Treatment
Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.
Psychotherapy
Regular monitoring for early signs during antipsychotic treatment allows for earlier intervention.
Medication
Certain medications are FDA-approved specifically to treat tardive dyskinesia; adjusting the causative medication may also be considered by the prescribing provider. Medication decisions should be made with a qualified prescribing healthcare professional. Do not start, stop, or change a prescribed medication based solely on information on this page.
Living With Tardive Dyskinesia
Never stop an antipsychotic medication abruptly without medical guidance; report any new involuntary movements to your prescribing provider promptly.
When to Seek Professional Help
Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.
Emergency Situations
If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.
Outlook
Outcomes vary; some cases improve with treatment or medication adjustment, while others persist, making early recognition important.
