Objective: The aim of this study is to determine the course of tardive dyskinesia (TD) during continuous medication with first generation antipsychotics.
Subjects And Methods: Patients of a psychiatric nursing home were assessed for TD by means of the AIMS on two occasions ten years apart.
Results: Out of 10 patients who met criteria for TD at baseline the global judgement of severity of the AIMS improved in 5, worsened in 4 and remained unchanged in one patient. The mean sum score of the AIMS slightly increased from 5.5 to 6.3. No patient developed movements that incapacitated him in his daily activities.
Conclusion: In concordance with the available literature these findings support the view that under continuous treatment with antipsychotics there is an equal chance for improvement as for deterioration. Progressive worsening to severe forms of TD was not observed.

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.
