Summary

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).

Interventions

DEVICE

Deep Insula-coil rTMS

Before administering TMS participants will undergo cue stimuli provocation, consisting of 32 professional color images of high calorie, sweet and savory food. This will follow with TMS. All subjects will receive prefrontal deep TMS (18 Hz, 2 sec on, 20 sec off, over approximately 30 min) 5 times per week, for 6 weeks, for a total of 30 sessions as a part of an active treatment phase. Maintenance treatment phase will include two sessions of rTMS (18 Hz, 2 sec on, 20 sec off, over approximately half an hour) weekly for the period of 6 weeks.
