Can anyone explain the Vitamin D component? It does not make sense that CCSVI causes MS when factoring in the geography theory of MS.

If we look to the genetic component of MS, it makes sense in the CCSVI paradigm. If, indeed, a certain percentage of the population is born with malformed veins draining the brain and spine (as happens in congenital renal, heart or liver disease) there might also be a correlation with inadequate vitamin D uptake and receptors. Many, many diseases are now being linked to low vitamin D levels, including autoimmune disease, heart disease and cancers. Genetic predisposition decides which disease manifests and how.IHateMS wrote:I have read this thread and most others here.

This is a fascinating theory. I agree about the fit. I am going to send the research to my SIL (who is a physician), my neuro & my PCP.cheerleader wrote: The thing is, if there is a mechanical cause to MS in CCSVI, it really doesn't matter how the other previous theories "fit" to make it "real." So far, 100% of MS patients tested have shown stenosis in the jugular or azygos veins.

I am down with the point of view. I have reiterated many times that all of what we thought we knew about MS will need to be reevaluated in terms of this material to see HOW it DOES fit. Stenosis seems to be a fact, and it changes everything."fit" to make it "real"
No, you're right this, Jamie...the heated and relaxed arteries will deliver more blood to the brain and create even more congestion, however it is the venous return to the heart which is most responsible for cooling the brain thru evaporation in the upper airways. If blood is congested in this area due to venous stenosis, the blood can not move thru efficiently enough to cool. Transit time is slowed. Wobbly, Marie and my Jeff have both shown improved heat tolerance since their procedures.Jamie wrote:I was looking for a heat connection, Mel's symptoms flare in the heat as do a lot of peoples.
It turns out one method of cooling (wikipedia) :
"Arterioles Vasodilation occurs, this is the process of relaxation of smooth muscle in arteriole walls allowing increased blood flow through the artery. This redirects blood into the superficial capillaries in the skin increasing heat loss by convection and conduction."
Now in my laymens terms if the body relaxes arteries to let more blood through then that blood has to come out again through the overstressed veins. Right?
Increasing reflux and thus symptoms.
Or clutching at straws?!
