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 is not a fatal disease. Except in rare cases of severe disease, most people with multiple sclerosis have a normal or near-normal life span and usually die from the same conditions (heart disease, cancer) that affect the general population. Still, MS symptoms can negatively affect quality of life.
