Sensorial frailty: age-related hearing loss and the risk of cognitive impairment and dementia in later life.

65 Among prospective cohort studies, there was a significant association for cognitive function in seven of eight domains, excluding fluency, and with cognitive impairment and dementia, but not for AD, while the association for vascular dementia (VaD) only approached significance. 65 In this meta-analysis, only studies using PTA to reduce conceptual heterogeneity were included, and while PTA remained the gold standard for clinical assessment of peripheral auditory dysfunction, CAPD was common in MCI and AD 8 and assessment of CAPD in people with ARHL might be useful for identifying older patients at increased risk of developing MCI and AD. 67 Furthermore, the full inclusion of hearing loss samples without a PTA cutoff may be the source of some heterogeneity.
