Tardive dyskinesia (TD) is a neurological disorder characterized by repetitive and involuntary movements, particularly in the facial muscles. There are a few different words that can be used as synonyms for this condition. These include tardive akathisia, tardive dystonia, and tardive chorea. Tardive akathisia refers to a feeling of restlessness that often accompanies the involuntary movements of TD. Tardive dystonia describes the development of muscle contractions and spasms in different parts of the body, which can be painful and debilitating. Tardive chorea refers to the rhythmic and involuntary movements that can often appear as dancing or jumping movements. Though different words are used to describe the various symptoms of TD, the underlying condition remains the same.
