Your Questions

What is CCSVI?

Do these reports of a possible association between insufficient vein drainage and MS mean that MS is caused by venous insufficiency?

Why can't Canadians get treatment in Canada, when it is available in countries like the US, Scotland, Australia and others?

The science surrounding CCSVI seems to be evolving rapidly. Are the seven studies funded by the MS Society of Canada and National Multiple Sclerosis Society (USA) still relevant?

Many people with MS can't afford to wait until these theories are proven or disproven, there is nothing else working for them. How can the MS Society not support treatment for CCSVI, at the very least on a compassionate basis?
