Copulatory Dyskinesia: Pathognomonic Manifestation of Tardive Dyskinesia

Source : https://tremorjournal.org/articles/10.5334/tohm.585/

Tardive dyskinesia (TD) is an iatrogenic movement disorder resulting from exposure to neuroleptics, also known as dopamine-receptor blocking agents (DRBAs). The disorder is characterized by repetitive, stereotypic movements involving various body regions including mouth, tongue, face, trunk and extremities. Unlike most iatrogenic disorders, in most patients the abnormal movements may persist or worsen after discontinuation of the offending agent [1 ].
