OBJECTIVE: Anorexia Nervosa (AN) is a complex disorder of unknown etiology that is characterized by disordered eating behaviors and specific psychopathology. In the course of anorexia around 50% will recover in the first 10 years, 25% will continue to experience symptoms but will be able to function, and 25% will go to develop chronic course, and by definition become severe treatment resistant(Tr). There is little if anything to offer to this population where the range of treatment options is limited to weight restoration interventions. Transcranial magnetic stimulation (rTMS) is a non-invasive intervention, which presents a particular interest in people with severe TrAN, specifically because of its ability to target deeper areas of the brain, such as insula, which has been argued to be a possible trait marker for AN. METHODS: This pilot study will test the efficacy and safety of deep-rTMS delivered with the H-coil in subjects with long standing treatment resistant severe anorexia nervosa (TrAN).
