Older adults with hearing loss have a rate of cognitive decline that is up to 40% faster than the rate in those with normal hearing, according to results of a new study. Those with hearing loss also appear to have a greater risk for cognitive impairment.

“I would argue going forward for next 30 or 40 years that from a public health perspective, there’s nothing more important than cognitive decline and dementia as the population ages,” said lead author Frank R. Lin, MD, PhD, assistant professor, otolaryngology, geriatrics, and epidemiology, Johns Hopkins University, Baltimore, Maryland.

“So from a big picture point of view, identifying factors that are associated with cognitive decline and dementia are important, in particular those factors that are potentially modifiable.”

Although the study did not find a significant association between hearing aid use and rate of cognitive decline, Dr. Lin is convinced that addressing hearing loss could have an impact greater than just improving quality of life.

The study was published online January 21 in JAMA Internal Medicine, formerly known as Archives of Internal Medicine.
