Body image distortion (BID) is a common symptom in eating disorders (ED), but its neurobiological underpinnings remain unclear. We aimed to discuss, through systematic review, BID's neurobiology studies that used neuroimaging tools ED patients. The review was developed using the guideline PRISMA, following 27-step checklist and four-phase flowchart. databases were consulted: Lilacs, Scielo, Pepsic, APA/Psycnet, Pubmed, Scopus, Bireme, Cochrane 1.692 articles found, 1.95% included this research. Anorexia nervosa (AN): Key findings altered activity amygdala, insula, anterior cingulate cortex, suggesting dysfunctions emotional response, body perception, cognitive processes. Additionally, have reported changes functional connectivity between brain regions reduced gray matter volume specific areas. Bulimia (BN): include alterations prefrontal decision-making, impulse control, regulation. AN/BN: While AN-R AN-P showed greater activation BN patients exhibited cortex occipital parietal lobes. Both groups presented excessive preoccupation with image, shared neural despite subtype-specific differences. Binge disorder (BED): one article exhibits increased left fusiform area (FBA) when viewing stimuli, an attentional bias towards body, without corresponding increases BID seems be linked paralimbic structures (cingulate insula), default-mode network, parietal, temporal, regions. These areas are associated subjective self, ego, perceptual suggest may judgment error self-reference, leading dysfunctional behaviors as attempt resolve distortion.
