RELATIONSHIP BETWEEN DYSGEUSIA AND DYSESTHESIA IN STROKE PATIENTS

Abstract

This study investigated the relationship between dysgeusia and dysesthesia in stroke patients and evaluated the effect of carbamazepine therapy. Twenty-four patients with dysesthesia of the face, oral cavity, or tongue were divided into two groups: with and without subjective dysgeusia. Taste thresholds were objectively evaluated using the filter-paper taste test and electrogustometry. There was no significant difference in taste thresholds between the two groups. Carbamazepine had an effect on subjective dysgeusia in four of the eight treated patients. Dysgeusia with dysesthesia in stroke patients might be caused by disorders of the somatosensory pathway rather than disorders of the gustatory pathway.
