Multiple sclerosis (MS) is a chronic, inflammatory autoimmune disease that damages myelin, a substance that protects neurons in the central nervous system (CNS). It affects over 2.3 million people worldwide , and has four clinical forms, with relapsing remitting MS (RRMS) accounting for 87% of the cases . The cause of the disease is complex and not yet clear. Studies suggest that genetics, environmental factors, and infectious agents may all play a role in the development of MS . There is currently no cure for MS. Standard MS medications aim to reduce inflammation, protect myelin, delaying the progression of the disease. These medications fall into two broad categories: anti-inflammatory disease-modifying therapies, and remyelinating-neuroprotecting therapies .
