CCSVI is a radical proposal seeking to fundamentally change our understanding of MS. Proponents of this new hypothesis have failed to meet the burden of evidence for such a radical change. Results of the burst of research that has taken place over the last three years display the typical variability and noise for a null hypothesis – that the notion is not true. There is no convincing evidence that CCSVI exists, and now there is no convincing evidence that treatments based upon the CCSVI theory are effective. Further, these treatments are invasive and pose serious risks.
Despite low (but not zero) prior plausibility, the medical community has dedicated a significant amount of time and effort to doing serious research into the question of CCSVI. If it has any legitimacy, they want to know about it. They also want to back up their opinions with reliable evidence. Despite this, believers in CCSVI are enthusiastically weaving conspiracy theories to explain away legitimate scientific skepticism toward this new hypothesis.
