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.
There is a definite correlation between having multiple sclerosis (MS) and facing posttraumatic stress disorder (PTSD). Experiencing a life-threatening illness or severe medical condition such as MS is one type of event that might place a person at risk for developing PTSD. MS is a chronic disease of the nervous system.
