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 can affect people of any age. However, itâs most commonly diagnosed in people between the ages of 20 and 50 years. The average age when MS symptoms first appear is between the ages of 30 and 35 years. Researchers have found that MS affects different age groups differently. For instance, people who are diagnosed when they are 50 years or older typically have a more progressive disease course.
