The cause of hearing loss in older adults has been discovered by a study in the US.
Researchers at the University of South Florida (USF) identified a genetic biomarker for age-related hearing loss, which it is claimed is a major breakthrough in understanding and preventing a condition of ageing that affects tens of millions of people and greatly diminishes their quality of life.
In the nine-year study that was a collaboration between USF's Global Center for Hearing & Speech Research and the National Technical Institute for the Deaf at the Rochester Institute of Technology, it was found that the genetic mutation carried by those who are affected by age-related hearing loss is linked to speech processing abilities in older adults.
"Age-related hearing loss is a very prevalent problem in our society. It costs billions of dollars every year to manage and deal with it," said Dr Robert Frisina.
According to data from the National Institute on Deafness and Other Communication Disorders, men are more likely to experience hearing loss than women.
