en Internal Medicine Internal Medicine Original Research Original Research In an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (MS), an audiometric evaluation was performed and auditory brainstem responses (ABRs) were obtained. Stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of MS. 24 (RO%) patients had an abnormal ABR along with clinical signs of brainstem dysfunction at the time of assessment by magnetic resonance imaging (MRI), while those without such signs had no incidence of abnormalities. This is independent of the clinical classification of the patients. 113 116 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-298-539&slc_lang=en&sid=1 MASOOD KAVIANI 20031947532846005912 20031947532846005912 Yes From the E.N.T.
