Abstract

Background and Aim: Multiple sclerosis (MS) is neurological disease of the central nervous system. Central auditory nervous system can also be affected by MS. The present study aimed to evaluate monaural and binaural auditory processing in patients with MS.

Methods: This cross-sectional study was conducted on 45 patients with MS and 45 normal peers as controls aged 25–45 years. They underwent a central auditory processing test battery including the Persian versions of Buffalo model questionnaire (BMQ), staggered spondee word (SSW) test, quick speech in noise test (QSIN), phonemic synthesis test (PST), and two- pair dichotic digit test (DDT).

Results: The results of SSW test, QSIN test, PST, DDT and BMQ in the MS group were significantly different than in the control group (p≤0.001). The results showed the poor performance of patients compared to controls in some monaural and binaural auditory processing skills.

Conclusion: Central auditory processing disorder is common among patients with MS. The BMQ is a suitable screening tool for identifying affected people. Dichotic listening skills, phonemic processing and speech perception in noise are impaired in MS patients which can have significant impacts on their quality of life.
