A recent Morning Edition on NPR highlighted the role of hearing aids in slowing the rate of cognitive decline in older adults. The feature highlighted the work of Maharani et al (2018) that examined the relationship. Drawing data from the Health and Retirement Study (HSR), Maharani and colleagues showed that cognitive function based on episodic memory (word recall) was associated with hearing aid use and that decline in episodic memory was mitigated by reported use of hearing aids. The authors reported the rate of decline was reduced by 75 percent.
