Tardive dyskinesia (TD) is a heterogeneous, often persistent syndrome of involuntary hyperkinetic movements of the tongue, lips, face, trunk, extremities, and occasionally, the respiratory system. TD is associated with the use of dopamine receptor blocking agents, including antipsychotics. Estimates of the lifetime prevalence of TD in patients treated with antipsychotics range from between approximately 15% and 40%; higher rates have been reported in older patients (age greater than 55 years) and among postmenopausal women.
It is imperative to assess the severity and impact of TD on a patient's life to formulate an individualized plan for treatment optimization that will diminish the impact of TD. Key domains for assessing the overall impact of TD include social, physical, vocational, and psychological functioning as well as the impact of TD on the underlying psychiatric disorder.
