There are very few studies examining the effectiveness of Neurofeedback for depression. Hammond has studied whether Depression can be treated successfully with Neurofeedback in small samples showing promising results. See http://www.braincoreny.com/images/14221ae9.pdf?& to read his work in the area of both depression and anxiety. Hammond states in an article for the ISNR, that “Neurofeedback treatments for depression appear very promising not only in bringing relief from depression, but in modifying the underlying biological predisposition for becoming depressed. Neurofeedback focuses on retraining the brain, for example, reversing the frontal brainwave asymmetry, with the goal of producing an enduring change that does not require people to remain on medication indefinitely.”
