American study reveals striking results on the use of hearing aids

A recent American study has highlighted a strong link between the use of hearing aids and a reduced risk of developing dementia among older adults with hearing loss. The findings show that wearing these devices may lower the risk by as much as 61%.

According to the researchers, age-related hearing loss not only affects communication but can also have far-reaching consequences for brain health. The study revealed that the brain exerts extra effort to process sounds when hearing declines, which negatively impacts cognitive performance and accelerates mental deterioration.

The research tracked nearly 3,000 individuals over two decades. The data indicated that those who used hearing aids were less likely to develop dementia symptoms compared to those who did not. However, usage rates remain low, with only 17% of people with moderate to severe hearing loss using the devices.

Experts emphasize that addressing hearing loss early on is not only about improving quality of life in terms of communication, but also about serving as a key factor in maintaining cognitive health and preventing age-related neurological disorders.

These findings are consistent with previous studies, including research conducted by Johns Hopkins University, where scientists found that wearing hearing aids slowed the rate of cognitive decline by about 48% over just three years.

Professor Frank Lin, a specialist in hearing and cognition, stressed that managing hearing loss should not be considered secondary, but rather an effective preventive strategy against dementia—especially since social isolation caused by hearing loss can further accelerate cognitive decline.
