What Causes Muscle Atrophy?

Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune disease that affects the spinal cord and brain. It occurs when the immune system attacks myelin, a protective sheath covering the nerves. This causes disruptions and communication issues between an individual's brain and the rest of their nervous system. MS can be progressive, meaning it gets more severe over time. It can cause permanent nerve damage and deterioration. The symptoms of multiple sclerosis are extremely varied because they depend on the affected nerves and how much nerve damage has been done. Severe MS can cause patients to lose their capability of walking independently or walking at all. Some patients experience remission periods in which they have no symptoms. However, multiple sclerosis remains a chronic disease with no known cure. MS causes muscle atrophy because it impedes muscle movement through the nervous system. Some treatments can help speed recovery and manage symptoms.
