Van den Eynde F, Guillaume S, Broadbent H, Stahl D, Campbell IC, Schmidt U, Tchanturia K. Neurocognition in bulimic eating disorders: a systematic review. Objective: The aim of this study was to review the literature on neurocognition comparing people with a bulimic eating disorder in the acute phase of the illness with healthy controls (HC). Method: The review follows the PRISMA (preferred reporting items for systematic reviews and meta‐analysis) statement guidelines. Three databases (Medline, Web of Science, and Scopus) were searched combining the search terms ‘bulimic disorder’, ‘bulimia nervosa (BN)’, ‘binge‐eating disorder (BED)’ with terms referring to cognitive domains (e.g. ‘executive functions’). Results: Thirty‐seven studies on people with BN and four on people with BED were selected for review. Overall, sample sizes were relatively small [bulimic disorders: median and range 22 (12–83); HC: 27 (13–172)]. The diversity in methodology precluded a meta‐analytical approach. People with a bulimic disorder did not present with a clear neurocognitive profile. Inclusion of salient, disorder‐related stimuli (e.g. body weight/shape words) in the neurocognitive paradigms tended to generate differences between people with a bulimic disorder and HC. Conclusion: Neurocognition in bulimic eating disorders is under researched, and the available evidence is inconclusive. This review outlines strategies for further research in this area.
