Yes, we're still learning about CCSVI and so much yet to be learned. I think it's wonderful to finally have hope, but we have a long road to travel before we'll have any absolutes, if we ever will. MS is such a puzzle, and so many variables exist as each case of MS is different.
It's good to have hope - I am guilty myself of having hope that CCSVI will be my answer, as I've stopped DMDs (though have started and will continue LDN unless I have bad side effects which I haven't yet, lol). But I know in my heart that we don't have all the answers or the whole picture.
I tend to stay away from advising newbies, especially newly diagnosed people unless I have a very concrete example from my own experience or the research.
The best thing I think we can tell newly diagnosed people is to read, read, read, and learn to be their own advocates. We all have to ultimately make our own decisions about what treatment path to choose. At this point, it's far from being clear cut.
