Do hearing aids slow down cognitive decline? 



The Aging and Cognitive Health Evaluation in Elders, or ACHIEVE, study is a multicenter randomized trial to determine if treating hearing loss in older adults reduces the loss of thinking and memory abilities (cognitive decline) that can occur with aging.


The ACHIEVE study also looks at other health outcomes, results of which will be published over time, including: mental health and well-being, physical function, and health care use.


What ACHIEVE found:

In older adults at increased risk for cognitive decline, hearing intervention slowed down loss of thinking and memory abilities by 48% over 3 years.

Participants in the ACHIEVE study came from two distinct study populations: a group of adults who were already participating in a heart health study and a group of healthy volunteers who were newly recruited from the community. The 238 participants who came from the heart health study were, on average, older and had more risk factors for cognitive decline than the 739 new healthy community volunteers. 


When both group of participants were analyzed together, the hearing intervention was not better than the health education control on slowing declines in thinking and memory abilities, at the end of the 3-year study.


When both groups of participants were analyzed separately, researchers found that the effect of hearing intervention differed significantly between the two groups of participants: 

  • Hearing intervention benefited the heart health study participants the most. These participants were older and had more risk factors for cognitive decline. In this group, the hearing intervention reduced cognitive change by 48% over 3 years.

  • In the newly recruited healthy volunteer group, hearing intervention had no effect on reducing cognitive decline within 3 years.
