    The World Health Organization estimates that more than 350 million individuals of all ages have depression and approximately one-third of all patients with depression fail to respond to conventional antidepressant therapies like SSRI’s. The good news is that today, perhaps more than ever, good science is starting to illuminate some of the underlying biological mechanisms surrounding the development of depression. This new understanding may soon help the clinical world develop new approaches to treatment that may be vastly more effective and for a greater number of people than the traditional approaches.
