Tardive Dyskinesia

Tardive dyskinesia is a potentially irreversible hyperkinetic movement disorder resulting from prolonged exposure to dopamine receptor blocking agents, most commonly antipsychotics and, less frequently, antiemetics with central dopaminergic antagonism. The disorder arises from chronic dopamine D2 receptor blockade, leading to maladaptive neuroplastic changes within basal ganglia motor circuits and subsequent dopaminergic hypersensitivity. Established risk factors include cumulative drug exposure, advanced age, female sex, affective disorders, diabetes mellitus, and a history of extrapyramidal symptoms. Clinically, tardive dyskinesia is characterized by involuntary, repetitive, and purposeless movements involving the orofacial region, extremities, and trunk, which may persist or worsen after medication withdrawal. Diagnosis is primarily clinical and supported by standardized rating scales, particularly the Abnormal Involuntary Movement Scale. Management focuses on prevention through cautious prescribing of dopamine receptor blocking agents, dose minimization, and pharmacological treatment with vesicular monoamine transporter 2 inhibitors when indicated. Complications include functional impairment, social stigma, and reduced quality of life. Prognosis varies, with symptom persistence common despite intervention, underscoring the importance of early recognition and ongoing monitoring. This activity for healthcare professionals is designed to enhance learners’ competence in evaluating and managing tardive dyskinesia. Participants advance their mastery of the condition’s etiology, risk factors, pathophysiology, clinical manifestations, and evidence-based diagnostic and therapeutic approaches. Improved skills equip clinicians to collaborate effectively with interprofessional teams caring for patients with tardive dyskinesia.
