Progressive Relapsing Multiple Sclerosis (PRMS) is one of four internationally recognised forms of Multiple Sclerosis.
PRMS is characterised by a steady progression of clinical neurological damage with superimposed relapses and remissions. There is significant recovery immediately following a relapse but between relapses there is a gradual worsening of symptoms.
The following graph, showing level of disability over time, demonstrates a typical course of PRMS.
The Progressive Relapsing form of the disease affects around 5% of all people with multiple sclerosis. Some neurologists believe PRMS is a variant of the Primary Progressive form of MS.
Other forms of Multiple Sclerosis are:
Relapsing/Remitting Multiple Sclerosis
Secondary Progressive Multiple Sclerosis
