The increase in the prevalence of MS is actually also very easy to explain: fewer people are dying of it. Between 25 and 50% fewer. So, more people live with the disease, which means that more people have the disease, which means higher rates of MS.

Of course, it’s also completely untrue to say that the rates have doubled. At best, they’ve increased a little bit over the last few decades.
