Multiple Sclerosis (MS) is a neural disorder with an unknown triggering mechanism. This chronic, slowly progressive autoimmune disease is where the body's immune system attacks the myelin sheaths around nerve cells mainly in the brain and spinal cord (a process called demyelination), resulting in the damaged areas failure to transmit nerve impulses. Because the lesions can partially heal, it goes through characteristic phases of remission and relapse.
Initial symptoms of MS are often vague, such as blurred or double vision, fatigue and muscular weakness. Individuals are usually diagnosed between the ages of 20 and 40, when they present with symptoms like muscular weakness, numbness, incoordination, paralysis, convulsions, visual problems, bladder or bowel disturbances, mood swings, cognitive problems and difficulty in speaking. Symptoms vary greatly from patient to patient since almost every system of the body can be affected.
