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.
The study found that median life expectancy for people with MS was 76 years, compared to 83 years for those without MS. The authors examined the health records of 5,797 MS patients in Manitoba, Canada from 1984 to 2012 and compared them to a matched sample of 28,807 healthy individuals living in Manitoba as well.he study found that median life expectancy for people with MS was 76 years, compared to 83 years for those without MS.
