What best describes tardive dyskinesia?

Tardive dyskinesia is a movement disorder that develops after long-term use of antipsychotic medications that block dopamine receptors. It presents with involuntary, repetitive movements of the face, mouth, tongue, and sometimes the limbs—think grimacing, tongue protrusion, lip smacking, and choreiform or jerky limb movements. The underlying idea is that chronic dopamine blockade can lead to changes in dopamine receptor sensitivity in the brain’s movement circuits (especially the basal ganglia), producing these involuntary motions. This is a neurotoxic side effect linked to long-term antipsychotic therapy. It isn’t an anxiety state, a genetic disorder, or a seizure, which helps distinguish it from other conditions with similar symptoms.
