Abstrakt: Sensory impairments are common in older adult populations and have notable impacts on aging outcomes. Relationships between sensory and cognitive functions have been clearly established, though the mechanisms underlying those relationships are not fully understood. Given the growing burden of dementia, older adults with sensory deficits are an important and growing population to study in cognitive aging research. Yet, cognitive research sometimes excludes those with uncorrected significant/severe sensory deficits and often poorly or inconsistently assesses those deficits. Observational and interventional studies that exclude participants with sensory deficits will be limited in their generalizability to the narrower subset of the older adult population without vision or hearing impairment and may be missing an opportunity to study a growing population of older adults at higher risk of cognitive impairment. Strategies exist for adapting cognitive testing instruments, and inroads could be made into collecting normative data to inform ongoing research. Bringing together psychometricians with researchers who specialize in vision and hearing impairments could launch highly innovative research on both measurement methods and cognitive disease etiology, as sensory organs provide readily accessible neuronal and vascular beds that may show pathology earlier and elucidate innovative screening opportunities for early signs of cognitive disease.
