Research on hearing impairment and dementia risk is limited. This editorial explores how study biases may explain the link and calls for new research designs and biomarkers to clarify causation and inform prevention strategies.
Area of Science:
- Gerontology
- Neuroscience
- Epidemiology
Background:
- Growing interest exists in hearing impairment as a modifiable dementia risk factor.
- The precise association between hearing impairment and dementia remains poorly understood.
- Causation is not the only explanation for the observed association, impacting potential interventions.
