Several months ago I read a story written by a lady pediatrician who's husband had Alzheimer's. She had done some extensive research in nutrition relative to Alzheimer's and found that in many cases the brain needed more quality fats to operate normally.She decided to try coconut oil as an supplement to his diet. After 3 or 4 months she noticed a marked improvement in his cognitive ability. He hadn't been talking for quite some time when she implemented the new diet and the first she noticed was that he began to speak to her again. Of course the progress was slow but the physician continued to see measurable improvement in her husband. I don't know what the eventual outcome was but this improvement alone would be worth trying her methods. I have discovered that there are many credible medical practitioners that have shown incredible improvements in many ailments when the proper nutritional support is accomplished. Drugs can be helpful but in many cases a diet of complete quality nutritional components in the right combination will often offer a better outcome and one with less if any side affects. It might even help Mr. Campbell. "Always do your own research) There's a World of information out there.
