Types of MS

While there is no way to predict with any accuracy how a person’s MS will progress, four basic clinical patterns have been defined2:

• Relapsing-remitting MS: characterised by clearly defined attacks (relapses or exacerbations), which last from days to weeks and then subside with full or partial recovery and no noticeable disease progression between attacks.
• Primary-progressive MS is characterised by a gradual but steady progression of disability from the onset with no obvious plateaus or remissions or only occasional plateaus and minor temporary improvements.
• Secondary-progressive MS begins initially as a relapsing-remitting course that later evolves into a more consistently progressive course with or without relapses.
• Progressive-relapsing MS shows a steady progression in disability from the onset of the disease, but with clear, acute relapses (attacks) that may or may not have some recovery following the acute episode.
