Not Applicable
Terminated
Conditions
Anorexia Nervosa
Bulimia Nervosa
Interventions
Procedure: Transcranial direct current stimulation
Procedure: Transcranial magnetic stimulation
Registration Number
NCT02535780
Lead Sponsor
University of Colorado, Denver
Brief Summary

The primary aim of this study is to study how Repetitive Transcranial Magnetic Stimulation (rTMS) tailored to specific anorexia nervosa (AN) or bulimia nervosa (BN) brain activation alterations will promote recovery and to study how inhibitory tDCS (Transcranial Direct Current Stimulation) will reduce symptoms of body image distortion in a second sample of AN and BN groups.
