Tardive dyskinesia (TD) is a troubling side effect that may occur with long-term dopaminergic antagonist medications. TD manifests as involuntary movements of the tongue, lips, face, trunk, and extremities. It is most commonly seen in patients with schizophrenia, schizoaffective disorder, or bipolar disorder who have been treated with antipsychotic medication for long periods. However, TD can occur in other patients as well, even after periods of exposure to antipsychotic medication as short as 3 months. Given the serious and potentially irreversible nature of TD, accurate diagnosis is crucial, yet its symptoms can be easily mistaken for symptoms of mental illness or other side effects, making the diagnosis of TD challenging.
