Brain lesions area direct result of iron deposits in the brain. I do not know if they are reversible, but I intend to ask this question at the upcoming thal conference in Philadelphia (June 28-30, and CAF invites all who can come. There is no registration fee).
I have a long standing support of using natural chelators as a supplement to chelation drugs, because the natural chelators can access everywhere inside the body, including the brain and pituitary. Can IP6 actually make a difference? Well, while researching this topic, I found an article that describes the damage iron does in various organs. Two examples that are given concerning the pituitary glands and examples taken from 11 and 12 year old boys were used. Both showed iron deposits. Our moderator Sharmin's son is just a bit older than these boys. He has faithfully used IP6 along with a program of high antioxidants since he was 6. His pituitary was scanned. No iron was found and the pituitary was perfectly normal. IP6 and green tea extract can access everywhere in the body, including the brain.
Supplementing chelation with natural chelators shouldn't be just a recommendation. It should be an absolute.
