[Late-Onset Dyskinesia Occurring During Antipsychotic Treatment for Schizophrenia: Treatments for Tardive Dyskinesia].

Tardive dyskinesia is recognized as buccolingual dyskinesia, but also includes various involuntary movements, such as chorea, dystonia, myoclonus, and tremor. Tardive dyskinesia can be treated depending on the type of movement disorder present. Antipsychotics causing tardive dyskinesia should be reduced in dosage or should be discontinued. However, the treatment of schizophrenia is important, and neurologists must treat tardive dyskinesia in collaboration with psychiatrists taking care of patients with tardive dystonia. Various treatments, such as VMAT-2 inhibitors or tetrabenazine, reserpine, dopamine receptor antagonists, botulinum toxin therapy, anticholinergic agents, or deep brain stimulation, are trialed, depending on the type of movement disorder and the degree of severity of the disorder.
