EC-READ 2025 Project 3: The Effect of Hearing Aid Coverage Mandates on Cognitive Decline

Hearing loss, which affects two-thirds of Americans over the age of 70, is associated with an increased risk of cognitive decline and dementia. Traditional Medicare does not cover hearing aids, but some state Medicaid programs do. This project examines the impact of hearing aid access on cognitive decline and dementia, using data from the National Health and Aging Trends Study (NHATS) data. The project analyzes the effect of Medicaid hearing aid coverage requirements on various outcome variables related to dementia, including the self-reported results of cognitive tests, such as the clock drawing test, orientation memory, and executive function.
