Multiple sclerosis (MS) is one of the most significant autoimmune diseases of the central nervous system (CNS) and has been the focus of numerous scientific studies over the past decades. With rapid advances in medicine and technology, our understanding of the pathogenesis, diagnosis, and treatment of MS is continually evolving. This article summarizes the current state of medical knowledge on MS—with special emphasis on topics important to patients, their families, and anyone interested in understanding the condition.
Brief Description and Nature of the Disease
MS is a chronic, immune-mediated disease that affects the brain and spinal cord. In MS, the immune system mistakenly attacks myelin—the protective sheath covering nerve fibers—leading to inflammatory destruction (demyelination) and subsequent neurodegeneration. This disrupts the normal transmission of electrical impulses between the brain and the rest of the body and, over time, causes irreversible damage to motor, sensory, and cognitive functions.
MS typically appears in young adults, most often between the ages of 20 and 40, and affects women 2–3 times more frequently than men. The course of the disease can vary—from relapsing-remitting (alternating flare-ups and periods of remission) to progressive (a slow but steady worsening over time).
