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.
An attack is followed by a time of recovery when you have no few or no symptoms, called remission. It can last weeks, months, or longer. The disease doesn't get worse during these breaks. After 10 to 20 years, RRMS usually changes to a different type of MS called secondary progressive multiple sclerosis. You wonât have relapses as often, but the disease gets gradually worse.
