Description
Summary:The aim of this study was to evaluate the incidence of auditory and neurotological disorders in multiple sclerosis (MS). Twenty female and 9 male with a definite diagnosis of multiple sclerosis without signs of involvement of the brain stem underwent an audiological and an early auditory evoked potentials (EAEP). The wave forms were classified according to Jerger's (1986) classification. In 58 EAEP it was found 55% of type I (normal response) according to Jerger's classification in both sexes. Considering as an abnormal response the EAEP classified in type II, III, IV or V according to Jerger in at least one side, it was found 60% of abnormalities in females and 56% in males, totalizing 58,62% of all the studied subjects. The authors emphasize the use of EAEP in MS.
