The Effect of Obesity on Contralateral Suppression in Patients With Multiple Sclerosis

Otoacoustics Emissions Contralateral Supression Test

Source: ClinicalTrials.gov · Last updated 22 Aug 2025

Brief summary (registry, in English)

This study investigates how obesity may affect the auditory system in individuals with Multiple Sclerosis (MS). Specifically, it examines the brain's ability to process and suppress sounds (contralateral suppression). The test is painless and brief. It provides information about the condition of the auditory nerve pathways. The goal is to better understand how obesity may influence this system and to improve follow-up and support for individuals with MS.
