Answer 1

#. The precise cause of MS is unknown

Environmental theory :

-Theory is that an environmental trigger or an infectious agent initiates the autoimmune response in people with genetic susceptibility

environment: Vitamin D (higher incidence in norther hemispheres)

virus: exposure to the epsteim bar virus somehow triggering MS

#. Other theories include :-

Autoimmune theory:foreign agent such as a virus alters the immune system so that the immune system perceives myelin as an intruder and attacks it.

Genetic Theory: There are certain people like Eskimos and African Bantu essentially do not develop multiple sclerosis

Native Indians of North and South America, Japanese and other Asian groups have a low incidence. Chance increases in families where a first-degree relative has the disease. Thus, a brother, sister, parent, or child of a person with multiple sclerosis stands a one-percent to three percent chance of developing multiple sclerosis.
