Multiple Sclerosis (MS) is an autoimmune disorder where the body’s immune system attacks myelin, the protective covering for the brain, spinal cord and eyes. MS manifests in various symptoms, including, in some cases, hearing health.
This is known as sensorineural hearing loss, and while not a common symptom, it does affect 4%–10% of individuals with MS. This form of hearing loss, along with conditions like tinnitus, can be attributed to nerve damage or lesions in the brain that are typical of MS.
The Connection Between MS and Sudden Hearing Loss
The hearing loss symptom associated with MS is unlike the gradual hearing deterioration due to aging or noise exposure. This hearing loss is abrupt and usually impacts one ear, with rare instances where both ears are affected. The onset of sudden hearing loss, often accompanied by crackling or popping sounds, is typically during an MS flare-up and is usually connected to nerve damage in the brain.
Tinnitus: A Frequent Occurrence
Another symptom linked to MS-induced hearing loss is tinnitus. This condition is characterized by hearing ringing, buzzing or other sounds when there is no external sound source. If tinnitus arises during a period of MS remission, see your doctor.
Treatment for sudden hearing loss often involves a course of steroids, which can lead to a recovery period spanning several weeks to months. However, the recovery varies from individual to individual—some may only partially recover, while others might experience permanent hearing loss.
For individuals dealing with MS-related hearing loss, hearing aids can offer significant relief. These devices can help maintain existing hearing and manage the existing condition, thereby improving the overall quality of life.
If you’re dealing with hearing loss, whether related to MS or not, reach out to Center for Hearing & Speech to schedule an appointment for a hearing test.
