Multiple Sclerosis (MS) is an autoimmune disorder where the immune system erroneously attacks the protective sheath, called myelin, that covers nerve fibers in the brain, spinal cord and eyes.
This condition presents various symptoms, and, in a small percentage of patients (4% to 10%), MS can affect auditory functions, leading to sensorineural hearing loss. Although hearing loss and tinnitus tied to MS is rare, when it does occur, it is often due to nerve damage or brain lesions related to MS relapses.
MS and Sudden Hearing Loss
Unlike gradual hearing loss related to aging or prolonged exposure to loud noise, MS-related hearing loss can develop quickly. It typically impacts one ear, but it may occasionally affect both. This acute hearing loss is commonly a result of neural damage and may be accompanied by auditory sensations such as crackling or popping sounds, a result of an MS flare-up.
Tinnitus, characterized by hearing ringing, buzzing, or other phantom noises without an external source, can accompany hearing loss in MS patients. If you experience tinnitus or sudden hearing loss as a symptom of an MS relapse, see a doctor right away. Treatment options may include corticosteroids, with the potential for hearing to improve gradually over weeks to months. Recovery may consist of regaining partial hearing but is permanent in some cases.
Tackling Hearing Loss with MS
Hearing aids can be a helpful tool for improving social interactions if diagnosed with hearing loss due to MS. They can assist with staying present in conversations and also reduce the fatigue from listening.
Should you encounter signs of hearing loss related to MS or not, consider scheduling an appointment with Evergreen Speech and Hearing Clinic. Discussing the suitability of hearing aids with your hearing specialist is a constructive measure to maintain your current hearing and minimize further hearing loss.
