Hearing loss and its relation to cognition in Indian cohort: A behavioral and neuroimaging study.

ABSTRACT:

Introduction

Hearing loss (HL) is an unexplored modifiable risk factor that impacts 41% of the Indian population. This study aimed to determine the prevalence of HL, investigate the association between HL and cognitive impairment in older adults, and assess neuronal structures involved in HL and cognitive impairment using behavioral and magnetic resonance imaging (MRI).

Methods

This study assessed 589 individuals aged 45 and above using HearCheck handheld audiometry, cognitive testing, and MRI.

Results

Participants with HL are 1.69 times more likely to experience cognitive impairment compared to those without HL. Neuroimaging revealed significantly less gray matter in various temporal and hippocampal regions in individuals with HL and cognitive impairment as compared
