Progressive multiple sclerosis is a form of multiple sclerosis that is characterized as having nerve degeneration (the breakdown of nerves) in the absence of clinical episodes of inflammation. Researchers funded by grants from places such as the National Institutes of Health (NIH), the National Multiple Sclerosis Society, the International Progressive MS Alliance, and more are working to answer these common questions about progressive MS
THERE ARE THREE TYPES OF PROGRESSIVE MS:
1. Primary-progressive multiple sclerosis (PPMS) is characterized by steady worsening of neurologic functioning, without any distinct relapses (attacks or exacerbations) or periods of remission. The rate of disease progression may vary over time, but it is continuous.
2. Secondary progressive MS (SPMS) comes on after the relapsing-remitting disease course (RRMS).
3. Progressive-relapsing MS (PRMS) is the least common of the disease courses, occurring in approximately five percent of those with MS. PRMS is recognized by the same progression as PPMS, with occasional relapses—thus individuals with PPMS are re-diagnosed with PRMS when they experience a relapse.
