The course of Multiple Sclerosis (MS) is highly unpredictable and the onset and speed of progression to severe disability vary from patient to patient.

The extent of recovery from the initial damage, the frequency and severity of relapses, the level of disability and the length of remissions all vary from patient to patient.
