NPR: CCSVI has to be studied, neurologist says

A story on NPR's Morning Edition interviews Robert Zivadinov, professor of neurology, about a new theory Italian physician Paolo Zamboni has proposed that suggests multiple sclerosis is caused by chronic cerebrospinal venous insufficiency, or CCSVI, which can be treated by opening up the blocked blood vessels. "Even if the treatment is not useful for patients with MS, I don't think that we can abandon the idea of vascular involvement in MS," he said. "And I think this merits very detailed understanding of what is going on."
