Neurofeedback by Dr. Don Posson works!! It cleaned the cluster in my head, helps me focus, sleep better and get up in the morning refreshed ,staying away from depression. He described brain issues in terms of over-arousal, under- arousal and instability and sure enough, my brainwaves have been trained to improve on many levels. I have seen other clients with TBI, PTSD, and bi- polar issues recount their experiences how they improve greatly with this brain training too.
