Multiple Sclerosis (MS) is an autoimmune inflammatory disorder that is caused by selective demyelination of the central nervous system (CNS) axons. The exact cause is still vastly unknown; it is believed to bd a combination of immunologic, environmental, and genetic influences. Patients present with neurological symptoms based on the location of the demyelinated lesions. Treatment usually focuses on treating MS relapses and decreasing disease progression. Many medications treat MS based on the type that is diagnosed; there are four different types. Relapsing-remitting which has stable periods and exacerbations, primary-progressive which has worsening neurological function without relapse, secondary-progressive has an initial relapse course and becomes steady with the neurological decline and clinically isolated syndrome which is usually one episode without another one for a stable period but are at risk for a flare leading to MS.
