I have been following the story of Dr. Zamboni, an Italian vascular surgeon who claims that multiple sclerosis (MS) is primarily caused by blockages in the veins that drain blood from the brain. This results in backup of blood in the brain, leading to inflammation around the blood vessels and MS. He sought to find the cause and cure for MS because his wife suffers from this disease – and he claims to have found one in his own specialty.
New ideas in science
New ideas are presented in science and medicine all the time. This is healthy and necessary – we have to keep churning the pot so that new ideas can emerge and our thinking does not become calcified. But science is both a creative and destructive process, and most new ideas fall victim to the meat grinder of research and peer review. Ideally this process will take place mostly within the halls of science, and then those ideas that survive at least initial examination will start to penetrate the broader culture.
This is not what often happens today, however. With the internet and mass media, preliminary speculative studies are often presented to the public as if they are a stunning breakthrough. When the scientific community responds with their typical and completely appropriate skepticism, this may lead some to think that they are being stodgy or dogmatic, or even that a cover-up is in the works. The originator of the speculative claim is usually portrayed as a brave maverick, although sometimes the story can be framed as, “Brilliant scientist or dangerous crank? You decide.” When the topic is a new medical treatment, the stakes can be quite high. In this case many patients with progressive MS are seeking treatment with the so-called liberation procedure to treat the highly speculative CCSVI as an alleged cause for their MS.
This story has all the makings of the kind of scientific and medical drama the mass media loves. While the controversy rages, the science is quietly being done in the background, and the results are not heading in a favorable direction for Zamboni. A recent study, the largest to date, drives a further stake into the heart of CCSVI as a cause of MS. (more…)
