Does ms always progress the same way?

No: Ms disability progresses at a variable pace, influenced in part by age at symptoms onset, use of disease modifying therapy, effective use of rehabilitation strategies to optimize function. Genetic background also likely plays a key role in the aggressiveness of this disease. Cognitive reserve or "plasticity" of the CNS helps compensate for advancing disease longer.

No: The disease usually manifests itself with many of the same ailments but progression of the disease is never the same in two individuals.

Not at all: There are NO two MS pts who are alike, each has a unique course, and even if untreated, only a certain number sharply deteriorate. However, secondary progressive transition could occur in 50% at 10 yrs, 90% at 20 yrs, if disorder not effectively treated.

MS varies: MS is a variable illness. About 1/7 cases are very simple, with few attacks and symptoms. Many cases have multiple relapses, some cases result in progressive illness, and some rare cases are very aggressive or difficult to treat. MS has become a much more manageable illness with good outcomes over the past 20-30 years, although there are exceptions too.
