Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to communicate, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems.
Multiple sclerosis (MS) involves an immune-mediated process in which an abnormal response of the bodyâs immune system is directed against the central nervous system (CNS), which is made up of the brain, spinal cord and optic nerves. The damaged myelin forms scar tissue (sclerosis), which gives the disease its name. 2  When any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted, producing a wide variety of symptoms.
