Although TD has been observed after exposure to various substances (eg, levodopa, amphetamine, and metoclopramide), the prototypical TD is the orofacial (ie, buccolingual, masticatory) hyperkinesia induced by neuroleptics (antipsychotic dopamine D2 -receptor blockers). People with other movement disorders and those with diabetes mellitus are at increased risk of TD.
