BOSTON — A new study from Mass Eye and Ear investigators shows that individuals who report tinnitus, which present as a ringing in the ears in more than one out of ten adults worldwide, are experiencing auditory nerve loss that is not picked up by conventional hearing tests. The work is part of a P50 grant awarded by the National Institutes of Health (NIH) to Mass Eye and Ear researchers within the Eaton-Peabody Laboratories (EPL) for their work on cochlear synaptopathy, which is commonly referred to as “hidden hearing loss.” The results from this study provide a better understanding on the origins of tinnitus and are published November 30th in Scientific Reports.
“Beyond the nuisance of having persistent ringing or other sounds in the ears, tinnitus symptoms are debilitating in many patients, causing sleep deprivation, social isolation, anxiety and depression, adversely affecting work performance, and reducing significantly their quality of life,” said senior author Stéphane F. Maison, PhD, CCC-A, a principal investigator at Mass Eye and Ear, a member of Mass General Brigham, and clinical director of the Mass Eye and Ear Tinnitus Clinic. “We won’t be able to cure tinnitus until we fully understand the mechanisms underlying its genesis. This work is a first step toward our ultimate goal of silencing tinnitus.”
