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.
Research shows however that on average the life expectancy of a person with Multiple Sclerosis is around 7 years less than that of the rest of the population. Areas of particular concern are chest and bladder infections. As disability from Multiple Sclerosis increases so also does the risk from these type of infections.
