Abstract

Background

Age-related hearing loss (ARHL) is highly prevalent in older adults, and more than two-thirds above age of 70 years suffer from ARHL. Recent studies have established a link between ARHL and cognitive impairment; however, most of the studies have used verbally loaded cognitive measures to investigate the association between ARHL and cognition. It is possible that due to hearing impairment, the elderly may experience difficulty in following verbal instructions or completing tasks that heavily rely on hearing during cognitive assessments. This may result in overestimation of cognitive impairment in such individuals. This baseline cross-sectional study investigated the associations between untreated hearing loss and a number of cognitive functions using a battery of non-verbal cognitive tests. Further, association between hearing loss and psychological status of older adults was examined.
