Response: Age-related hearing loss, a common chronic condition among older adults, has emerged in the literature as a potential modifiable risk factor for dementia. This is of interest as current pharmacological therapies for dementias such as Alzheimer’s disease only offer symptom-modifying effects. Treatment of risk factors such as hearing loss may help delay the onset of dementia and may provide an alternate therapeutic strategy. However, there is variance in the research on hearing loss and cognition with some studies reporting a small or non-significant association. In this meta-analysis, we investigated this association and we only included observational studies that used standard assessments of cognitive function and pure-tone audiometry (the clinical standard).
