A new study published in The Lancet provides the most definitive evidence to date that chronic cerebrospinal venous insufficiency (CCSVI), a hypothetical syndrome of narrowed veins draining the brain that some believe is the true cause of multiple sclerosis (MS), is not associated with MS.
In a science-based world, this study would be yet one more nail in the coffin of this failed hypothesis. But that’s not the world we live in.
