I have a question for you. How can anyone possibly tell if a disease modifying drug is preventing relapses if no one really knows how MS works, everyone's MS is different and it is impossible to predict when and how often you will have a relapse? How can studies possibly test this? Even if you are testing a group of people with MS and averaging everyone's response to a medication, how is that really saying anything definitive? Why are the disease modifying drugs only approved for RRMS? Correct me if I'm wrong, are there any approved for other types of MS like PPMS? How does someone with RRMS know if they are doing well because of a medication or if it is the natural course of their disease going into remission? How does anyone know that?
