Multiple sclerosis is a chronic autoimmune disease of the central nervous system that is characterized by inflammatory processes that can lead to demyelination and loss of axons and neurons, which is major cause of permanent disability. Multiple sclerosis usually begins around the age between 20 and 40 years and disease course is typically relapsing-remitting.
