Multiple Sclerosis (MS) is an immune mediated disease of the central nervous system (CNS). It usually has onset between 20 and 40 years of age and is the leading non-traumatic cause of nervous system disability in young adults. In MS the white blood cells attack the myelin sheath.

If an identical twin has MS the other twin has a one in four chance of developing MS. Geography is also a factor for MS. MS is more prevalent in cooler climates. MS is also more common in the northern states of the United State. Canada’s rate of MS is double that of the United States.
