1. Remember that quackery seldom looks outlandish.
2. Ignore any practitioner who says that most diseases are caused by faulty nutrition or can be remedied by taking supplements.
3. Be wary of anecdotes and testimonials.
4. Be wary of pseudomedical jargon.
5. Don't fall for paranoid accusations.
6. Forget about "secret cures."
7. Be wary of herbal remedies.
8. Be skeptical of any product claimed to be effective against a wide range of unrelated diseases—particularly diseases that are serious.
9. Ignore appeals to your vanity.
10. Don't let desperation cloud your judgment!
I think penicillin, as mentioned above, is effective against a variety of infections. Infections are related diseases. Penicillin is not effective against infections and cancer, for example.
We've had anecdotes in the CCSVI world, we've had some paranoia against pharma. I don't think we've had pseudomedical jargon, as that refers to something that is impossible to measure, and blood flow is possible to measure. But our attempts to figure out why it works might border on this. We are not medical professionals, although we're doing pretty well for laymen, I think.
It's not a secret cure, as Dr. Zamboni has shared his insights with the scientific community as part of the process of scientific development. Venoplasty is not an herbal remedy.
There are practictioners who are treating CCSVI in many different diseases (MS, Alzheimer's, ALS, Parkinsons, migraine, etc). Those are unrelated diseases, although they are all neurological. If CCSVI syndrome is a disease in its own right, then what is being treated is CCSVI syndrome, not the other diseases. I don't think we yet have an adequate diagnostic process, to know who has CCSVI and who does not prior to a venogram plus ivus being done. This is a concern.
And MS is a disease in which there is legitimate desperation and fear of what's next and suffering. It might not cloud our judgment (beyond what cogfog already does), but it's going to factor into any decision.
I don't see grounds for dismissing CCSVI as quackery. It is being researched through the scientific process. It involves angioplasty of blocked blood vessels; angioplasty has been well established as a treatment for blocked blood vessels.
