My research has now convinced me that MSA is an auto-immune disease as are MS, fibromyalgia, parkinsons and many others.
The only treatment for MSA seems to be to do with diet. We are now trying the Wahls Protocol which is a Paleo type diet with lots of fresh fruit and veg, meat etc. all organic where possible. We still have Bowen weekly.
Baden was diagnosed 5 years ago and is still mobile though on bad days we use the wheelchair. Check out http://www.terrywahls.com
