Multiple sclerosis treatment is debunked by researchers in Canada

'Liberation therapy' to widen veins in multiple sclerosis sufferers has been shown to be worthless after 'gold standard' study

A surgical treatment pioneered in Europe that was sought out by thousands of desperate people with multiple sclerosis has been categorically debunked by Canadian researchers.

"Liberation therapy" to widen narrowed veins from the brain and spinal cord was devised by the Italian surgeon Dr Paolo Zamboni, who suggested in 2009 that the neurological disease could be triggered by a build-up of iron where the blood did not flow freely.
