Purpose Of Review: To provide an update on the frequency of antipsychotic-induced tardive dyskinesia and its management in patients with schizophrenia spectrum disorders in studies published since the last systematic review in 2008.
Recent Findings: Recent data about antipsychotic-induced tardive dyskinesia in patients with schizophrenia underscore the superiority of newer generation antipsychotics (21%) over first-generation antipsychotics (30%) with respect to prevalence and incidence rates. Regarding recently tested management strategies, the new vesicular monoamine transporter 2 inhibitors valbenazine and deutetrabenazine have been found to be effective and may be considered as first-line pharmacotherapy for tardive dyskinesia. Owing to quality issues of randomized controlled trials and/or small sample sizes, limited and conflicting evidence remains for most treatment strategies.
Summary: The reviewed literature reveals lower prevalence rates of antipsychotic-induced tardive dyskinesia in patients treated with newer generation compared with first-generation antipsychotics. The evidence of vesicular monoamine transporter 2 inhibitors as a first-line therapy for tardive dyskinesia is well supported by several controlled clinical trials.

Aim: We aimed to create a rat model of drug-induced parkinsonism and tardive dyskinesia by chronic administration of haloperidol and examine the expression of direct and indirect pathway markers in the striatum of the model rats.
Methods: We treated 21 rats, 14 with haloperidol decanoate and 7 with placebo. The number of vacuous chewing movements per 2 min was counted, and haloperidol-treated rats were classified into two groups: mild and severe tardive dyskinesia.

Antipsychotic medications are used to treat a psychological condition called 'Schizophrenia'. However, its long-term administration causes irregular involuntary motor movements, targeting the orofacial regions. Glycyrrhizic acid (GA) is a naturally occurring triterpene saponin glycoside obtained from the roots of the Glycyrrhiza glabra (liquorice) plant and well known for its antioxidant, antiapoptotic and neuroprotective abilities.

We present a case of a 66-year-old man, where 18F-FDG PET/CT revealed intense FDG uptake in the tongue, lips, cheeks, and chewing musculature and distinct activation of the somatosensory and motor cortex corresponding to the mouth and tongue. The patient suffered from buccolingual masticatory syndrome, characterized by tardive dyskinesia, meaning uncontrollable, repetitive movements of the tongue, lips, cheeks, and masticatory musculature. In this case, the buccolingual masticatory syndrome was caused by metoclopramide antiemetic treatment.
