tardive dyskinesia an iatrogenic disorder produced by long-term administration of antipsychotic agents; it is characterized by oral-lingual-buccal dyskinesias that usually resemble continual chewing motions with intermittent darting movements of the tongue; there may also be choreoathetoid movements of the extremities. The disorder is more common in women than in men and in the elderly than in the young, and incidence is related to drug dosage and duration of treatment. In some patients symptoms disappear within several months after antipsychotic drugs are withdrawn; in others symptoms may persist indefinitely.
