Mediators and Moderators of Auditory Training
This project, R01AG077725 funded by the National Institute of Aging, seeks to train over 1,000 participants in different variants of auditory perceptual learning with a focus on the potential of auditory training to mitigate hearing issues that promote risk of development of Alzheimer’s disease and related dementias (ADRD). Reports from the Lancet Commission, and others, show midlife hearing loss is one of the greatest predictors of late-life dementia, and hearing aids protect against development of ADRD. While this has promoted a push for greater distribution of hearing aids, other research suggests that central hearing processes may be greater predictors of onset of ADRD than peripheral hearing (as addressed through hearing aids). The overarching goal of this proposal is that better understanding of mechanisms of auditory training, with focus on speech in noisy environments, can address the most prevalent hearing complaints reported by people as they age, and in turn mitigate transition to ADRD.
