Came across this article based on a University of Columbia study.

According to study,  suggests wearing a hearing aid helps slow down cognitive impairment in seniors with hearing loss. It is well known that hearing loss is tied to mental decline. Thus, preserving or maintaining hearing health can help maintain a strong mind. Researcher Dr. Anil Lalwani said, “We know that hearing aids can keep older adults with hearing loss more socially engaged by providing an important bridge to the outside world. In this study, we wanted to determine if they could also slow the effects of aging on cognitive function.”
