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.
Most people with MS have a relapsing-remitting disease course. They experience periods of new symptoms or relapses that develop over days or weeks and usually improve partially or completely. These relapses are followed by quiet periods of disease remission that can last months or even years.
