What Menon's team found was a connection between the amount of iron present in the brain and the patient's level of disability.

Study Reveals Iron Deposits, No CCSVI
According to Menon, what they found was a “much higher level of iron—well above what you would expect in age-matched controls—in the MS patients’ brains.”
Researchers also looked at the diameter of the patients’ neck veins during the MRI scans. Insufficient drainage of the jugular veins is part of Dr. Paolo Zamboni’s theory of a phenomenon called chronic cerebrospinal venous insufficiency (CCSVI), which may contribute to nervous system damage in MS.
This study, along with other resent research, revealed no connection between vein drainage and MS.
“While iron in the brain correlates with the disability in the subjects, the iron in the brain does not correlate in any way with the actual diameter of the jugular veins in these patients,” explained Menon. “So the Zamboni hypothesis is incorrect insofar as iron is related to some kind of obstruction in their veins, but the fact is, there is iron at very early stages of MS.”
Menon’s group identified subtle changes in the brain's white matter in those with CIS, indicating that damage occurs even in the very early stages of MS. The white matter damage also correlated with the amount of iron in the brain, suggesting that iron plays a significant role in the MS disease process and resulting disability.
