| pubmed-article:1975104 | pubmed:abstractText | While understanding of the major clinical and ethical issue of tardive dyskinesia would be greatly facilitated by the development of an isomorphic or homologous animal model, particularly in rodents, this has proved to be a highly contentious issue. The literature on orofacial function in rats administered neuroleptic drugs for substantial proportions of their adult lifespan is reviewed. It reveals the emergence of late-onset orofacial movements in a number of studies, but very early-onset movements or no effect in others. Potential explanations for these discrepancies are considered, and ways of resolving such inconsistencies are suggested. The relationship of these various orofacial phenomena to dopaminergic and non-dopaminergic function, and to clinical syndromes, is critically evaluated. | lld:pubmed |
