Causes And Risk Factors Associated With Vocal Cord Paralysis

Multiple Sclerosis

Multiple sclerosis is a neurological condition that may lead to the paralysis of a single vocal cord, and it also increases the risk of weakness in the vocal cords. The condition develops when the patient's immune system attacks myelin, a protective covering for the body's nerves. This results in communication difficulties between the brain and body, and it eventually leads to nerve damage and deterioration of the nerves themselves. Symptoms of multiple sclerosis include fatigue, tremors, dizziness, double vision, and pain or tingling in various parts of the body. In terms of the vocal cords, multiple sclerosis patients may experience slurred speech, and they may also have a hoarse voice and trouble with swallowing and speaking. To prevent progression of certain types of multiple sclerosis, doctors may prescribe ocrelizumab, beta interferons, dimethyl fumarate, or glatiramer acetate. Voice therapy may be particularly helpful for patients experiencing vocal cord paralysis or weakness.
