RESUMO
The main symptoms of Meige's syndrome are involuntary eye blinking with muddled speech and uncontrollable contraction of the platysma muscle characterized by segmental, primarily oromandibular, dystonia (hyperkinesia). It can also develop after long-term medication of first- and second-generation antipsychotics. Here, we report the case of a Japanese female schizophrenic patient comorbid with Meige's syndrome and hyperthyroidism. We discuss the relationship between the three diseases, that is, schizophrenia, Meige's syndrome, and hyperthyroidism. Our intention is to consider the important role of the cerebral basal ganglia, where little attention has been given in regard to schizophrenia and Meige's syndrome. A part of this article was presented in a poster section at the joint congress of the 28th Annual Meeting of the Japanese Society of Clinical Neuropsychopharmacology and the 48th Annual Meeting of the Japanese Society of Neuropsychopharmacology held in 2018.
