FDA warns against multiple sclerosis treatment
Los Angeles Times

An experimental treatment for multiple sclerosis has caused death, strokes, nerve damage and abdominal bleeding and has no proven benefits for sufferers of the disease, the Food and Drug Administration warned Thursday.

Known as liberation therapy, the treatment targets chronic cerebrospinal venous insufficiency — or CCSVI — a narrowing of the veins in the head and neck. It involves inserting balloons or stents into veins to widen them in an attempt to relieve the symptoms of MS.
