The average life expectancy for someone with MS is 35 years after the symptoms begin. This represents a life expectancy of 95 percent of someone who does not have multiple sclerosis. Most people with the disease can function effectively; however, a rare form of acute MS can be fatal within weeks.
MS is more common in individuals of northern European descent. Women are more than twice as likely to develop multiple sclerosis as men. Multiple sclerosis usually affects people between the ages of 20 and 50 years, and the average age of onset is approximately 34 years.
