Abstract
AbstractObjectiveFunctional neuroimaging studies have found differential neural activation patterns during anticipation‐related paradigms in participants with eating disorders (EDs) compared to controls. However, publications reported conflicting results on the directionality and location of the abnormal activations. There is an urgent need to integrate our existing knowledge of anticipation, both rewarding and aversive, to elucidate these differences.MethodWe conducted an activation likelihood estimation (ALE) meta‐analysis to quantitatively review functional neuroimaging studies that evaluated differences between brain correlates of anticipation in participants with and without disordered eating. PubMed, Web of Sciences, PsycINFO, Medline and EMBASE were searched for studies published up to November 2022. Exploratory sub‐analyses to check for differences between reward and non‐reward anticipation among all anticipation paradigms.ResultsTwenty‐one references met the inclusion criteria for meta‐analysis. The meta‐analysis across anticipation all tasks identified a significant hyperactivation cluster in the right putamen in participants with disordered eating (n = 17 experiments) and a significant hypoactivation cluster in the left inferior parietal lobule (n = 13 experiments), in participants with disordered eating compared to controls.ConclusionsThese findings and sub‐analyses of reward‐ and non‐reward‐related cues suggest potential pathophysiological mechanisms underlying anticipatory responses to rewarding and aversive cues in ED.
