Meds approved and prescribed are not working on the placebo affect, that had already been studied during pre clinical and clinical trials before release to public.
Research shows changes in brain chemistry while taking meds to help stave off negative symptoms originating from the disorder.
I may be way off here, but I have not heard of any pharmacy filling scripts for "sugar pills" (placebos) but at the same time, I cannot say that there are people that haven't been inspired by the power of suggestion and/or placebo effect.
Chemical imbalances in the brain DO EXIST, and they DO cause changes in behaviours, that we do NOT choose to experience or display.
Not being everything in black and white,I'm sure the grey area allows for what this author is spouting, I'm more inclined and lean towards science, and what studies have revealed and what can be done.
Just my opinion(s) at the same time that concept of one healing oneself through positive thinking, just doesn't cut it, when there are physical things,controlled or out of control in the brain, and/or body behind it all.
2 cents added here, or just discard if you wish.
