Multiple sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system. The disease attacks the protective myelin covering of the white matter tracts in the central nervous system, causing inflammation and often destroying the myelin in patches. In its most common form, MS has well defined attacks followed by complete or partial recovery. The severity of MS, progression and specific symptoms cannot be predicted at the time of diagnosis, but with advancements in research it may be possible to cure or even innoculate for this disease.
