Abstract

We describe two patients with speech-induced oromandibular dystonia. One patient showed mainly jaw dystonia, while the other patient had lingual dystonia. A brain MRI revealed acute cerebral infarctions in the midbrain near the substantia nigra in the patient with jaw dystonia, while the patient with the lingual dystonia showed no structural lesions. Symptoms in both patients were partly improved with sensory tricks, such as chewing gum or holding a candy in their mouths. Their symptoms were completely recovered with anticholinergic therapy.
