Neural Network Alterations Across Eating Disorders: A Narrative Review of fMRI Studies

Abstract

BACKGROUND: Functional magnetic resonance imaging (fMRI) has provided insight on how neural abnormalities are related to the symptomatology of the eating disorders (EDs): anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). More specifically, an increasingly growing number of brain imaging studies has shed light on how functionally connected brain networks contribute not only to disturbed eating behavior, but also to transdiagnostic alterations in body/interoceptive perception, reward processing and executive functioning. METHODS: This narrative review aims to summarize recent advances in fMRI studies of patients with EDs by highlighting studies investigating network..
