Association of Age-Related Hearing Loss with Cognitive impairment

Abstract

Background: In recent years, there has been increasing research interest in the correlation between hearing loss and cognitive impairment, two conditions that have demonstrated a significantly correlation. Aim: We aimed to synthesize and review those investigating the relationship between activity-related hearing loss and cognitive impairment in the elderly. Materials and Methods: To examine and estimate the association between ARHL and cognitive function, cognitive impairment, and dementia through a systematic review and meta-analysis.Data sources and study selection: A search of PubMed, the, Medline, CINAHL, and Web of Science databases using the cross-referencing of retrieved studies and personal files for potentially eligible studies was performed. Keywords included hearing, correlation cognitive impairment, older people, correlation/association between hearing loss (HL) and cognitive impairment dementia, and Alzheimer disease. Cohort and cross-sectional studies published in peerreviewed literature and using objective outcome measures were included. Results: Hearing loss has been identified as a modifiable age-related condition linked to dementia. Early detection and diagnosis of hearing loss in the elderly, cochlear implant therapy, and other rehabilitative treatments can prevent cognitive decline and Alzheimer’s disease. Conclusion: Due to the lengthening of the average age of the population and the increase in the proportion of elderly people, the international approach is to improve the QOL of the elderly, to increase their healthy longevity, self-service ability, and the ability to perform daily activities by early detection of hearing and cognitive loss. Individualized geriatric care to reverse cognitive decline is important.
