No.

There is no guarantee the Disease Modifying Drugs (DMDs) will slow progression but that is what they are supposed to do. For some the DMDs seem to work, others keep progressing regardless.

This disease is a crapshoot.

Mild MS is only mild until it isn't.....Having said that I am still considered mild even as I am into my 21st year of diagnosis. But even if you are considered mild this disease can be very difficult and can leave residual symptoms.
