To the Editor.—
Delwaide and Hurlet, in their article, "Bromocriptine and Buccolinguofacial Dyskinesias in Patients With Senile Dementia" (Archives 1980;37:441-443), describe eight women ranging in age from 71 to 87 years. These authors have shown improvement in a group of patients with only orofacial dyskinesias using a dopamine agonist, bromocriptine mesylate. It is unclear where these patients fit in relation to those with Meige's disease (dystonic spasms of the upper and lower face sometimes associated with spasms of the trunk and proximal limb muscles) who also have been helped by another dopamine agonist, apomorphine.1 However, they apparently are not part of a continuum of dyskinesias that follow neuroepileptic agents or those induced by dopaminergic treatment in patients with Parkinson's disease.It is our experience that many elderly and some middle-aged patients with orofacial dyskinesias have edentulous mouths, malfitting dentures, no good opposing teeth, or severe periodontal disease, all of
