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.
Multiple sclerosis occurs predominantly in younger persons, with those aged 15 to 60 most likely to be diagnosed. The average age of diagnosis is about 30 years; however, multiple sclerosis has been identified at all ages. While multiple sclerosis can occur in children, this is very rare. About 2.5 million people worldwide have been diagnosed with MS; of those, about 400,000 live in the United States.
