IMHO this paper was meant to be presented at a vascular symposium, not a peer reviewed "neuro" magazine. Its audience are vascular doctors. And as Ernts says (and the article clearly states), it's preliminary. Maybe that is why it lacks MRIs and the reason it appears to some as it couldn't appeal to a neuro (even more if this neuro is stuck in his politically correct view of this disease).
Anyway, I can understand some dose of skepticism, but this is (IMHO) very different from other research, here we have a very defined pathological finding, the stenosis of veins that disturbs the flow of blood from the brain and spine. And I think that this finding, the stenosis, is clearly proven beyond doubt imho (and the photos from this paper are amazing!). Of course, there remains the causality to be "proved" (which this paper addresses, btw).
And yes, we need another study replicating this findings, but if they find that the only people that have relapses are the ones whose veins got blocked again, well .....
PS: I'm Fernando from Argentina. I have been lurking in this site for about a year. I'm waiting for confirmation but my neuro says he's pretty sure I have ms. Please, consider this as my introduction. Btw, I'm not a doctor just a patient.
PS: Thank you to all the people here, especially to Cheer, Jeff, Marie and Chris. You are very brave and smart and full of passion, your stories have inspired me. Really, thank you.
