Transcranial Treatments in Eating Disorders

Not Applicable

Terminated

• Conditions: Anorexia Nervosa; Bulimia Nervosa

• 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.
