Zivadinov testifying to the Canadian Senate

Here is an interesting (though long) presentation to the Canadian Senate by Zivadinov and the subsequent Q&A session: Zivadinov at Canadian Senate.  While I don't agree with him that people should only have CCSVI treatment as part of randomized trials (for people who are going downhill fast, you would be taking away one of the few hopes they have of returning some quality of life), and I still don't see good evidence for his arguments that MS may cause CCSVI, I think it is worthwhile to watch the entire video for the sake of getting a feel for current expert understanding of CCSVI.
