Alzheimer Disease Clinical Trial
— EARHLIOfficial title:
Early Age-Related Hearing Loss Investigation (EARHLI): A Randomized Controlled Trial to Assess the Mechanisms Linking Early Age-Related Hearing Loss and Alzheimer's Disease and Related Dementias
Early Age-Related Hearing Loss Investigation (EARHLI) is a single site study that will randomize late middle age adults to either a hearing intervention (including hearing aids) or a health education intervention. Participants will be followed for 1 year. This study will provide information on reducing cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD).
