Facial chorea occurs in the context of a systemic movement disorder (eg, Huntington disease, Sydenham chorea). Chorea is a random, flowing, nonpatterned set of movements. A related disorder, spontaneous orofacial dyskinesia of the elderly, is observed primarily in the edentulous. It usually responds to proper fitting of dentures.
