Age of onset is between 20 – 40 Age of onset is between 20 – 40 years. Usually it is 21 – 25 years, in years. Usually it is 21 – 25 years, in women – 2 – 3 years earlier. In women women – 2 – 3 years earlier. In women the incidence of MS is 1.5 – 2 times the incidence of MS is 1.5 – 2 times higher than in men.higher than in men.
Nowadays there are about 2 mln Nowadays there are about 2 mln people with MS all over the worldpeople with MS all over the world

In Ukraine the incidence of MS is In Ukraine the incidence of MS is 15 per 100 000 people. But it is 15 per 100 000 people. But it is much more higher in western much more higher in western regions (25 per 100 000 people) regions (25 per 100 000 people) than in eastern and southern than in eastern and southern ones (6 – 8 per 100 000 people).ones (6 – 8 per 100 000 people).

Different etiologic agents provoke Different etiologic agents provoke autoimmune mechanisms. The autoimmune mechanisms. The result of this process is myelin result of this process is myelin destruction. At the beginning of the destruction.
