- Relapsing-remitting (RR) MS
Most people with multiple sclerosis (MS) have a type called relapsing-remitting MS (RRMS). It usually starts in your 20s or 30s. … These are called relapses. An attack is followed by a time of recovery when you have no few or no symptoms, called remission.
- Primary- progressive (PP) MS
Primary Progressive (PPMS) Primary progressive MS affects about 10-15% of people diagnosed with MS. It has this name because from the first (primary) symptoms it is progressive. Symptoms gradually get worse over time, rather than appearing as sudden attacks (relapses).
- Secondary-progressive (SP) MS
Secondary progressive MS (SPMS) is a stage of MS which comes after relapsing remitting MS in many cases. Neurologists generally agree secondary progressive MS is a “sustained build up of disability, independent of any relapses”. Most people with relapsing remitting MS will eventually develop secondary progressive MS.
- Progressive-relapsing (PR) MS
Progressive-relapsing multiple sclerosis (PRMS) refers to a pattern of relapses within primary-progressive MS (PPMS). About five percent of MS patients have the progressive-relapsing form of the disease. PRMS is the least prevalent form of MS.
