This sounds interesting, but before anyone starts changing their lifestyle based on this, you should be aware that not only isn't this a double-blind trial, there's no control group, and the results lump together subjective and objective improvement (in other words, 9 of the 10 either actually got better, or just thought they got better, possibly through the placebo effect). Also, the article mentions neuropsychological testing done on one of the subjects, demonstrating his decline, but then there's no mention of whether he was retested after the treatment to see if there was any measurable improvement! And no mention of any objective testing of the other 9 subjects, either before or after the treatment. This strikes me as odd, given that neuropsychological testing is the most sensitive way of measuring cognitive decline.
