MS reduces life expectancy by only about ten-fifteen years, and about half of the patients survive thirty years or more from onset. (Joy JE, Johnston RB, 2001) Approximately eight-five percent of MS patients begin with relapsing-remitting disease, as in optic neuritis, or several separate systems at the same time, for example, combined motor and sensory problems.
