'''Multiple sclerosis (MS)''' - an autoimmune disease that effects every patient differently based on the neurologic lesions inflicted throughout the body. While some can go through their lives with relatively mild symptoms and short periods of relapse, others can become incapacitated within years or even months. Defined by Nylander and Hafler, MS is a "multifocal demyelinating disease with progressive neurodegeneration caused by an autoimmune response to self-antigens in a genetically susceptible individual."<ref name ="MS Nylander & Hafler">PMID:22466660</ref> Inflammation is the primary cause of damage in MS, and though the effects of the disease are well known, and various treatments exist for the disease, the exact identity of an antigen or infectious agent that causes the initiation of a myriad of symptoms is unknown.<ref name='MS:Pathogenesis and Treatment'>PMID:22379455</ref> | '''Multiple sclerosis (MS)''' - an autoimmune disease that effects every patient differently based on the neurologic lesions inflicted throughout the body.
