About

Age-related hearing loss (ARHL) is the third most common health condition affecting older adults after heart disease and arthritis and is the fifth leading cause of years lived with disability worldwide. Many hearing-impaired older adults avoid or withdraw from social contexts in which background noise will make it difficult to communicate, resulting in social isolation and reduced communication with family and friends.Social isolation and loneliness have been linked to numerous adverse physical and mental health outcomes, including dementia, depression, and mortality, and they may also lead to declining physical activity and the development of the syndrome of frailty. In this project it is hypothesized that untreated ARHL represents a distinct route to developing Late-life Depression (LLD) and that individuals with comorbid ARHL/LLD are unlikely to respond to treatments (i.e., antidepressant medication) that do not treat the underlying hearing problem. Initial studies suggest remediation of hearing loss using hearing aids or cochlear implantation may decrease depressive symptoms acutely and over the course of 6 to 12 months follow-up. However, the clinical significance of these findings is obscured by lack of rigorous control groups, failure to objectively document hearing aid compliance, and enrollment of study populations lacking syndromal depression or even a threshold symptom score.

Full description

This study will conduct the first clinical trial possessing these design features 40 individuals will be recruited who are aged ≥60 years, diagnosed with a clinically significant depressive disorder, and have moderate ARHL with impaired speech discrimination. Comprehensive baseline psychiatric, audiometric, neuropsychological, and functional assessment will be performed. Participants then will be randomized to receive antidepressant medication (AD) treatment plus full amplification hearing aids or antidepressant medication plus low amplification hearing aids over a 12-week prospective trial. Data from this study could suggest a novel therapeutic strategy for LLD and thereby mitigate its public health burden, while also contributing to the increased recognition and treatment of ARHL more generally.
