I recently was tweeted about an interesting study about the effects of psychotherapy. In a study authored by Jakob Koch of Christian-Albrechts University in Kiel, Germany, it was suggested that psychotherapy with depressed patients is associated with chemical changes in the brain.
This is pretty exciting stuff. I've seen many studies that associate psychotherapy with behavior change or change in self-report of moods. I've never seen a study that has associated psychotherapy with actual biological change in brain chemistry. This study does that. The research found that psychotherapy, in-and-of-itself, was demonstrated to be associated with positive changes in brain chemistry.
