Tardive Myoclonus, a rare disorder, presents as brief jerks of muscles in the face, neck, trunk, and extremities.
Tardive Tourettism resembles Tourette syndrome and occurs during or after treatment with dopamine antagonists. Typically, it begins in individuals older than 21 years, whereas Tourette syndrome commonly occurs by the age of 7 years old. Tardive tourettism is characterized by frequent, multiple motor and vocal tics, echolalia, echopraxia, coprolalia, and copropraxia. Tics may be suppressed temporarily while inner tension builds; this inner tension is relieved by an explosion of tics. Tardive tourettism may occur with other tardive dyskinesias as well.
Tardive Tremor is a hyperkinetic movement disorder associated with long-term treatment with dopamine antagonists.
