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 has a male predominance, as documented in 3 of 4 large studies. One study of 203 patients with histopathologically confirmed MSA demonstrated a male-to-female ratio of 1.3:1.0. The mean patient age at onset is 54.3 years, with a range of 33-78 years.
