Abstract
Background: Although the primary aetiology of Eating Disorders (ED) remains unknown, research suggests a complex interplay of biological, psychological, and cultural or environmental factors. This paper aims to systematically review the literature on neuroimaging studies that measure socio cognitive factors, in the context of body dissatisfaction and EDs in young people. Specifically, our aim was to identify patterns in the findings linked to social media type behaviours. Methods: The review was conducted in accordance with PRISMA guidelines using PubMed, Scopus, and Web of Science databases. 799 papers were identified in the database search and 38 studies were selected based on exclusion and inclusion criteria. Selected studies were assessed using the National Institute of Health study quality assessment tool. Results:
Findings point to state related impairments in inhibitory control and salient emotional processing. Anorexia Nervosa(AN) showed impaired set shifting abilities, working memory and decision making, while altered activation in attention networks and associated difficulties with conflict resolution were seen for Bulimia Nervosa(BN) and Other Specified Feeding and Eating Disorders(OSFED). AN and BN also demonstrated altered sensitivity to food related stimuli in striatal regions, suggesting aberrant top down emotional cognitive control. ED participants also show deficits in body representation, impaired control over social behaviours and altered integration of visual and body perception. Discussion: These findings support the notion that socio cognitive dysfunctions in ED are underpinned by a distributed network of structural and functional brain changes which influence the way young people with ED interact with and respond to social media, and ultimately places at them at increased risk for body image disturbances.
