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.
The thinking used to be that multiple sclerosis progressed more quickly in people diagnosed at an older age. Indeed, a study published in February 2013 in the Journal of Neurology, Neurosurgery & Psychiatry found that children diagnosed with MS took longer to develop secondary-progressive disease (32 years) than adults diagnosed with MS (18 years), and they also took longer to reach disability milestones.
