Scientists from the Department of Clinical Research at the University of Southern Denmark found that hearing loss is associated with a 7% increased risk of developing dementia. On the contrary, using hearing aids helps preserve cognitive abilities. results published In JAMA (Journal of the American Medical Association).
573,088 Danes over the age of 50 participated in the study, which was conducted between January 2003 and December 2017. Researchers collected information about the participants’ health status and assessed their cognitive abilities using appropriate tests. The results showed that hearing loss increased the risk of developing dementia by 7%.
It has also been found that people with hearing loss who do not use hearing aids are 20% more likely to develop this condition. Using sound amplification devices for hearing problems is associated with a significantly reduced risk of developing dementia (6%).
Scientists have suggested that cognitive decline resulting from hearing problems is associated with less social interaction and difficulty thinking due to the need to constantly listen and reallocate brain resources to sound processing. More research is needed to better understand the relationship between dementia and hearing impairment.
The researchers also noted that dementia and hearing loss are not an inevitable part of the aging process. They recommended undergoing regular examinations to detect disorders and start treatment on time.
