Longitudinal Associations of Subclinical Hearing Loss With Cognitive Decline.

ABSTRACT:

Background

Several studies have demonstrated that age-related hearing loss is associated with cognitive decline. We investigated whether subclinical hearing loss (SCHL) or imperfect hearing traditionally categorized as normal (pure-tone average ≤25 dB) may be similarly linked to cognitive decline and risk of incident mild cognitive impairment (MCI)/dementia.

Methods

Participants from the Baltimore Longitudinal Study of Aging were cognitively normal adults at least 50 years old with cognitive assessments from 1991 to 2019 and pure-tone average ≤25 dB measured between 1991 and 1994 (n = 263). The exposure was hearing based on the better ear pure-tone average. Outcomes were test scores in various cognitive domains. Multivariable linear-mixed effects models were developed to ana
