Which statement about tardive dyskinesia is UNTRUE?

• A. It can always be reversed by discontinuing psychotropic medication
• B. It is a movement disorder
• C. It is associated with long-term antipsychotic use
• D. It can appear after extended treatment

Answer: (A)

Tardive dyskinesia is a late-onset, medication-induced movement disorder that results from long-term dopamine D2 receptor blockade, typically from antipsychotic use. It often emerges after extended treatment and presents with involuntary, choreiform movements of the face, tongue, and sometimes the limbs. The statement that it can always be reversed simply by stopping the psychotropic medication is not true; while reduction or discontinuation can help some individuals, many experience persistent or even irreversible symptoms despite stopping the drug. Because of that, the idea of guaranteed reversal is incorrect, whereas the other points—being a movement disorder, and its association with long-term antipsychotic use and appearance after extended treatment—are accurate.
