Neurology Advisor (6/16, Basilio) reports a study found that “approximately one-third of dementia cases may be attributed to audiometric-measured hearing loss among older adults.” Researchers included 2,946 older participants in the study, 61.1% of whom “had clinically significant hearing loss on audiometry.” They found the population attributable fractions (PAF) “of 8-year incident dementia from mild or greater audiometric hearing loss was 32.0%; PAFs from mild and moderate or greater hearing loss were similar, while self-reported hearing loss was not associated with an increased risk for dementia.” Furthermore, a “greater proportion of dementia was attributable to any measured hearing loss among participants aged 75 years and older vs those younger than age 75 years, primarily due to larger PAFs among those 75 years and older who had moderate or greater hearing loss.” The study was published in JAMA Otolaryngology-Head & Neck Surgery.
