First time we began to work with eating disorders, we used to hear the chronic course of the illness and the long-term treatment that our patients would need. When you have a team trained in brief psychotherapy, but not in this specific area, it sounds as just the opposite you try to reach with your patients. National guidelines however are full of psycho-educational and cognitive-conduct treatment's models, without any other validated kind of treatment. However, it was our experience that solution focused or problem focused therapy were also two clinical effective approaches to many psychiatric problems. In fact, we had a mature consult, in which as far as two thirds of patients had become, some way chronic. Problem was, as far as we can imagine, if that was a disease's effect or a lack of a deeper intervention, which were wider than those classic. So, we classified our patients in resistant or not resistant, and doing so we add brief therapy to the first group, reevaluating every week each intervention and the course of the illness. By doing so, we found that chronicity was, in same cases, just the result of limited treatments. Here we have analysed some chronic patients with a bad course and the alternatives that let them to recover.
