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.
MSA usually progresses more quickly than Parkinson's disease. There is no remission from the disease. The average remaining lifespan after the onset of symptoms in patients with MSA is 7.9 years. Almost 80% of patients are disabled within five years of onset of the motor symptoms, and only 20% survive past 12 years.he cause of MSA is not conclusively known and no specific risk factors have been identified, although research indicates that a prion form of the alpha-synuclein protein may be the cause of the disease. Around 55% of cases occur in men, with typical age of onset in the late 50s to early 60s.
