Study Refutes Controversial Theory About Cause Of MS

shutterstock_88515778Researchers finally put to rest a controversial theory regarding the cause of multiple sclerosis. Scientists from the McMaster University have stated that there is no evidence that impaired blood flow or blockage in the veins located in the neck and head is associated with the debilitating disease. The results of the findings are published online by PLOS ONE.

The findings debunk a previous theory that has become controversial. The said theory states that MS is associated with abnormalities in the drainage of venous blood from the brain. It was in 2008 that Italian researcher Paolo Zamboni stated that angioplasty, a procedure to clear blockage in the veins, will help MS patients. The so-called Liberation Treatment then got a flood of response from the public, most especially from MS patients trying to find any form of relief of treatment for their disease.

The research involved evaluating 200 participants, half of whom were patients with multiple sclerosis and the other half were people with no history of any neurological condition. All of the participants took an ultrasound of deep cerebral veins and neck veins. MRI scans of the neck veins and brain were also taken. The research team included a radiologist and two ultrasound technicians who had taken training in the Zamboni technique given at the Department of Vascular Surgery of the University of Ferrara.

After the scans were evaluated, the researchers found no evidence of abnormalities in the internal vertebral and jugular veins or even in the deep veins found in the brain in both the MS patients as well as the healthy group. This provides clear evidence that goes against the supposed benefits that a venous angioplasty may offer to MS patients.
