How fast does progressive MS progress? The authors of a 2015 study reported that the average time that it takes for a person with a diagnosis of PPMS to reach a score of 4.0 is 8.1 years. The authors also found that the time it takes to reach 8.0 can vary, but on average, this takes about 20.7 years.
Can relapsing MS turn into progressive MS? Prior to the availability of the approved disease-modifying therapies, studies indicated that 50 percent of those diagnosed with relapsing-remitting MS (RRMS) would transition to secondary-progressive MS (SPMS) within 10 years, and 90 percent would transition within 25 years.
What is the life expectancy of someone with progressive MS? Those diagnosed during the ages of 20 to 50 can still live another 25 to 35 years. There have been significant MS treatments that increased life expectancy as a result of improved lifestyle and better healthcare. Other treatments that can slow the progression of MS include: “Disease-modifying” therapies.
What is the difference between progressive and relapsing MS? PPMS is progressive with symptoms getting worse over time, while RRMS may present as acute attacks with long periods of inactivity. RRMS may develop into a progressive type of MS, called secondary progressive MS, or SPMS, after a certain time.
