Conditions: Multiple Sclerosis, Obesity, Hearing Loss
Interventions: DPOAE with Contralateral Suppression
Countries: Turkey (Türkiye)
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.
