Characterizing Variability in Hearing Aid Outcomes in Among Older Adults With Alzheimer's Dementia (NCT04240561)

๐ŸŸข Recruiting Observational / Diagnostic โš™๏ธ Medical Device Protocol Sponsor: Northwestern University

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This current translational project, funded by NIH, aims to better understand the impact of various signal modification strategies for older adults with Alzheimer's dementia and its potential precursor, known as amnestic mild cognitive impairment. The investigators hypothesize that adults with Alzheimer's dementia represent an extreme case of restricted cognitive ability, such that very low working memory capacity and overall reduced cognitive capacity will limit benefit from advanced signal processing. Thus, the investigators hypothesize that adults with Alzheimer's dementia will receive greater benefit from acoustically simple, high-fidelity hearing aid processing that minimally alters the acoustic signal.
