Evidence of low dopaminergic activity in elderly women with spontaneous orofacial dyskinesia.
Evidence of low dopaminergic activity was found in elderly women exhibiting spontaneous orofacial dyskinesias. The dyskinesia was significantly reduced by haloperidol. The results are not compatible with dopamine receptor supersensitivity in this dyskinesia.
