title: Spastic dysphonia and denervation signs in a young man with tardive dyskinesia.
abstract: Pathophysiological theories of tardive dyskinesia (TD) suggest the possibility of structural changes in the central nervous system of patients with TD. This report describes a case of choreoathetoid dyskinesia and spastic dysphonia associated with clinical and electromyographic signs of muscle denervation. The findings of this case suggest that the neurological syndrome originates within basal ganglia nuclei but may also extend to the peripheral neuromuscular system.
