I just came across this link on the BBC Health -
"More than 55% of multiple sclerosis patients have been found to have constricted blood vessels in their brains, a US study says.
The preliminary results are from the first 500 patients enrolled in a trial at the University of Buffalo.
The abnormality was found in 56.4% of MS patients and also in 22.4% of healthy controls.
The MS Society said it was intriguing but not proof that this caused MS - as one leading expert claims. "
