My opinion is that the ticking time bomb analogy is a possibility.
We won't know for 10 years or so.
However as was said, CCSVI is nothing to be complacent about.
Reflux of venous blood into the brain, and the hypoxia caused by slowed transit of blood through the brain are happening in CCSVI, whether you are 'healthy' or not. Spurious iron deposits are probably happening.
The harmful consequences of the venous malformations of CCSVI can, and will, be demonstrated and quantified.
The prevalence of CCSVI, depending on how convinced you are of the Buffalo data, seems to be much higher than the presence of 'MS' in the general population. That may mean there is an additional factor besides CCSVI that triggers 'MS'. Or it may not. I think genes are behind it either way. CCSVI is congenital.
The natural history of CCSVI is unknown, and status as a healthy person sounds on the surface as if it may not be threatened by a diagnosis of CCSVI.
However, it is difficult to imagine the mechanisms of CCSVI, causing reflux, slowed transition of blood through the brain and spine, and lowering of its oxygen levels, whether they are intermittent and posture-dependant or not, being indefinitely tolerated by healthy people. Having seen the "before" videos, I think if I had a diagnosis of CCSVI and was otherwise healthy I would worry, and might even seek treatment. I have several siblings, with various auto-immune problems who may do that.
That CCSVI may be prevalent outside the 'MS' population, should not be a consideration, for people with CCSVI formerly diagnosed as 'MS'. That Drs. Zamboni and Zivadinov had differing, though compatible results means, to me, that some of the results obtained by Dr. Zivadinov and possibly by Dr. Zamboni as well, must be reproduced by other researchers. Fortunately trials are already underway.
In the meantime, though, no-one need wait for more research, to have the state of their own health examined, and corrected. Liberation not only works, it saves lives. There may someday soon be something even better, but for now Liberation is the best we have.
