Multiple Sclerosis and Other Inflammatory Demyelinating Diseases T2 Adams and Victor's Principles of Neurology, 10e YR 2014 FD 2014 PB The McGraw-Hill Companies PP New York, NY SN 978-0071794794 LK accessmedicine.mhmedical.com/content.aspx?aid=57624842 RD 2021/04/23 AB It has long been the practice to set apart a group of diseases of the brain and spinal cord in which destruction of myelin, termed demyelination, is a prominent feature. To define these diseases precisely is difficult, for the simple reason that there is probably no disease in which myelin destruction is the exclusive pathologic change. The idea of a demyelinating disease is an abstraction that serves primarily to focus attention on one of the more striking and distinctive features of one group of pathologic processes. Another unifying feature of most of these processes is the participation of an inflammatory reaction in proximity to demyelination. The most common and important inflammatory demyelinating disease is multiple sclerosis (MS).
