Question

Quizplus · Accepted Answer

Tardive dyskinesia is primarily caused by the chronic use of some types of antipsychotic drugs that block dopamine receptors in the brain. This often occurs after long-term use of these medications, particularly among elderly patients, and can result in involuntary movements of the face, tongue, and limbs. Other causes of dyskinesia, such as lead or mercury poisoning or viral infections, are less common.
