Hearing loss may accelerate cognitive decline in older adults

Washington, January 22 (ANI): Hearing loss in older adults appears to be associated with accelerated cognitive decline and cognitive impairment, a study has suggested.

Frank R. Lin, M.D., Ph.D., of The Johns Hopkins Center on Aging and Health, Baltimore, studied 1,984 older adults (average age about 77 years) enrolled in a prospective observational study that began in 1997-1998.

A total of 1,162 individuals with baseline hearing loss had annual rates of decline in test scores that measured global and executive function that were 41 percent and 32 percent greater, respectively, than those among individuals with normal hearing. Compared to those individuals with normal hearing, individuals with hearing loss at baseline had a 24 percent increased risk for incident cognitive impairment, according to the study results.

"Our results demonstrate that hearing loss is independently associated with accelerated cognitive decline and incident cognitive impairment in community-dwelling older adults," the researchers said.

"The magnitude of these associations is clinically significant, with individuals having hearing loss demonstrating a 30 percent to 40 percent accelerated rate of cognitive decline and a 24 percent increased risk for incident cognitive impairment during a six-year period compared with individuals having normal hearing," they added.

The researchers suggest that, on average, individuals with hearing loss would require 7.7 years to decline by five points on the 3MS (the Modified Mini-Mental State Examination, a commonly accepted level of change indicative of cognitive impairment) compared with 10.9 years in individuals with normal hearing.

"In conclusion, our results suggest that hearing loss is associated with accelerated cognitive decline and incident cognitive impairment in older adults. Further research is needed to investigate what the mechanistic basis of this observed association is and whether such pathways would be amendable to hearing rehabilitative interventions," the study concluded.

The finding was published Online First by JAMA Internal Medicine, a JAMA Network publication. (ANI)
