Multiple sclerosis theory dealt a blow by studies – Los Angeles Times
Now research published online in the Annals of Neurology undermines the theory — called chronic cerebrospinal venous insufficiency by its creator, Italian researcher Paolo Zamboni.
In one study, conducted by German scientists, ultrasound imaging tests of the veins around the brains and nervous systems of 56 multiple sclerosis patients found that blood flow was normal in all but one person. A control group of 20 healthy patients had similar blood flow.
The second study, conducted in Sweden, used a different type of imaging test to compare blood flow in MS patients and a group of healthy people; both had similar amounts of blood vessel blockage.
