In a study published in Parkinsonism & Related Disorders, Frei et al employed an expert Delphi panel to address longstanding confusion over the terms “tardive dyskinesia” and “tardive syndrome.” The panel of neurologists and psychiatrists agreed that “tardive syndrome” should serve as the umbrella term for all persistent involuntary movements induced by dopamine receptor blocking agents (DRBAs), reserving “tardive dyskinesia” specifically for classic manifestations involving orobuccolingual stereotypy and chorea of the extremities. The study emphasized the importance of consistent terminology.
