The idea that depression and other mental health conditions are caused by an imbalance of chemicals in the brain is so deeply ingrained in our psyche that it seems almost sacrilegious to question it. However there is one large problem with this theory: there is absolutely no scientific evidence to support it. Recent reviews of the research have demonstrated NO LINK between depression, or any other mental disorder and an imbalance of chemicals in the brain. We are being sold a bill of goods. There needs to be a new direction taken in the research and treament of depression and mental illnesses. What we have available now is no better than a placebo.
