Welcome "AKA" Heather...
Thanks, we've got that presentation up, but it's nice to see it again
There are studies stating that men or African Americans are affected more by a progressive form of MS. In the CCSVI paradigm, I believe this is because they are diagnosed later, and the blockage has created more damage by the time they get to the doctors. We may find that African Americans or men have more blockage in the azygos, leading to a more progressive disease profile.
More people need to be tested, to get magnetic resonance venography, so that the doctors may begin to unravel these genetic/sex patterns in CCSVI, to see if there are any correlations. Time will tell...(I say that alot these days!)
