Tardive dyskinesia (TD) is a group of delayed-onset iatrogenic movement disorders caused by dopamine receptor-blocking medications that can manifest as orobuccolingual stereotypy, dystonia, akathisia, tics, tremor, chorea, or as a combination of different involuntary movements. Abnormal movements can persist for years despite discontinuation of the offending drug. In many cases, TD can be an irreversible condition, resistant to pharmacological treatment.
