Tardive Blepharospasm and Meige Syndrome during Treatment with Quetiapine and Olanzapine.

Meige syndrome, which has been presented in tardive syndromes, is a form of blepharospasm accompanied by oromandibular dystonia with manifestations over the face, jaw, and neck. A blepharospasm can be induced by antihistamines, dopaminomimetic or sympathomimetic drugs, or long-term exposure to dopamine antagonists. Atypical antipsychotics have less extrapyramidal side effects because of a weak dopamine D2 receptor binding affinity or a strong antagonistic effect to serotonin 5-HT2a receptor and have been known to cause less tardive dyskinesia than typical antipsychotics. Thus, in literature, atypical antipsychotics are recommended for the treatment of psychosis in cases of tardive dyskinesia. The potential risk factors associated with the development of tardive dyskinesia are extrapyramidal symptoms' history, diabetes mellitus, affective disorder, female gender, older age, and long-term therapy with neuroleptics at higher dosages. As reported below, a patient with an affective disorder who had quetiapine-induced oromandibular dystonia and olanzapine-induced Meige syndrome after antipsychotic augmentation in different stages of the disease process was presented.
