I would like to believe that this is true, however there is a right way to introduce a new cure and there is a wrong way. Large scale clinical trials must be made to prove it's efficiency and effectiveness. Even what you say is true and the procedure helped the majority of patients where was the results of the study published?
I may not know as much about MS as a medical professor, but isn't MS caused by the damaging on the myelin lawyer. How can clearing arteries that lead to the brain reverse the damages done to the myelin lawyer and the brain's white matter?
I'm fully aware that drug treatments are not cheap and many of them have their own risks and horrible side effects, that's why there are so many progressive multifocal leukoencephalopathy lawsuits, but giving false hope to MS patients is highly unethical.
