Bigelow RT, et al. JAMA Netw Open. 2020;3(7)e2010986.

Methodology
Cross sectional study on adults in USA using data from 2017 National Health Interview Survey, 25 665 adults included in analysis to investigate the association between HL, psychological distress, and mental health care utilization among adults in the United States.

Findings and recommendations

Hearing loss (HL) was significantly associated with psychological distress and the association between HL and psychological distress was stronger than that for many other health conditions (e.g., diabetes, hypertension).
Adults with moderate HL were 1.53 times more likely to seek mental health services compared to those without HL.
Consider hearing loss as a potential modifiable risk factor for psychological distress.
Hearing aids may reduce psychological distress in individuals with moderate HL.

Huber M, et al. Ear Hear. 2025; Published online September 15, 2025.

Methodology
Cohort study in two tertiary research centers of 61 adult patients indicated for CI in Austria and Germany to investigate whether an improvement in hearing after cochlear implantation (CI) was associated with changes in depression and cognitive performance

Findings and recommendations

Hearing ability (speech recognition and subjective hearing) improved significantly 12 months after CI.
Mental health scores decreased significantly; clinical depression cases reduced from 37% pre-CI to 17% post-CI.
CI effectively improves hearing and reduces mental health impact, regardless of age.

Methodology

Controlled, observational study of 87 adults in three groups, 44 normal hearing, 26 fitted with CI and 17 with untreated hearing loss in Australia to examine how cochlear implantation affects depression, anxiety and stress levels.

Findings and recommendations

Cochlear implantation was associated with lower anxiety and stress scores at 12 months compared to untreated hearing loss.
Depression scores increased over time in both CI and HL groups, remaining higher than in the NH group.
Anxiety and stress scores in CI recipients were comparable to NH controls after 12 months, while HL group scores worsened.
Include mental health screening in cochlear implant candidacy and post-operative care to identify and address issues early.
Train audiologists in mental health literacy to improve counseling and referral practices for CI recipients.
