People who treat hearing loss with hearing aids or cochlear implants regain rich conversations, escape isolation, and may even protect their brains and lifespans, a new systematic review and meta-analysis from the University of Southern California reveals.

The findings suggest that “hearing devices may help prevent the social disconnection and broader health consequences that can follow untreated hearing loss," said lead study author Janet Choi, MD, MPH.

Previous research has shown that over time, social withdrawal can reduce mental stimulation and increase the risk of loneliness, anxiety, depression, cognitive decline and dementia. It has also linked chronic social isolation to biological and neurological changes, including increased brain inflammation and alterations in brain structure.

Choi and colleagues' analysis included 65 previously published studies, encompassing over five thousand participants, on how hearing aids and cochlear implants affect three key measures: social quality of life; perceived social handicap, which refers to the limitations and frustrations hearing loss can create in social situations; and loneliness.

The researchers found that adults using hearing devices felt more socially connected and less limited in social situations. They were better able to engage in group conversations and felt more at ease in noisy or challenging listening environments.

Participants also reported feeling less socially handicapped by their hearing loss, with fewer barriers and frustrations during interactions and an improved ability to stay engaged without feeling excluded. The authors noted that this increased confidence can help users connect more easily with family, friends and colleagues, leading to stronger feelings of belonging and reduced social anxiety.

Those with cochlear implants reported the most improvement in their social quality of life. This is likely because cochlear implants offer greater hearing restoration than hearing aids, especially for individuals with more severe hearing loss, the authors suggested. As a result, they may experience more noticeable improvements in social engagement once their hearing is restored.

Furthermore, Choi said, "While our study didn't directly measure cognitive outcomes, the improvements we saw in communication and social engagement suggest that by restoring clearer communication, hearing devices may help preserve cognitive health by keeping the brain more actively involved and people more connected."

The findings "add to a growing body of research showing that hearing health is deeply connected to overall well-being," she added.
