Application of self- regulation (biofeedback) strategies in the treatment of addictive and compulsive disorders including overeating. We believe there is substantial evidence indicating biofeedback can be effective with most addictive disorders, and we intend to see if it can also be used to reduce overeating, which has reached epidemic proportions in the United States and other developed countries. We believe this work will also apply to the problems of decreased quality of life due to addictions, and inappropriate mixing of medications as aging progresses.
