“…Specifically, we ask whether the literature points towards behavioral impulsivity and/or compulsivity, and thus yields mechanistic insights into lapses of control during binge eating episodes. Our review extends recent work on the same constructs in anorexia and bulimia nervosa (Howard et al, 2020) and complements other up-to-date reviews (Cury et al, 2020) by including a wider range of tasks as well as animal and functional neuroimaging studies. Importantly, we note consistencies and inconsistencies across and within translational levels.…”

Recurring episodes of excessive food intake in binge eating disorder can be understood through the lens of behavioral control systems: patients repeat maladaptive behaviors against their explicit intent. Self-report measures show enhanced impulsivity and compulsivity in binge eating (BE). Task-based neurocognitive investigations can tap into processes that lead to such lapses of control. In this systematic review, we synthesize the insights into processes relevant to BE provided by neurocognitive research on behavioral impulsivity and compulsivity in BE in humans and animals, published between 2010-2020. Findings on impulsivity are heterogeneous. Findings on compulsivity are sparse but comparatively consistent, indicating an imbalance of goal-directed and habitual control as well as deficits in reversal learning. We propose to address heterogeneity related to mood states and the temporal dynamics of symptoms and to systematically differentiate contributions of body weight and BE. It is necessary to ascertain the reliability of the metrics employed to further scrutinize the compulsivity findings in order to unravel the computational mechanisms of a potential reinforcement learning deficits.

“…The findings of studies in BED on executive functioning however are mixed and the number of studies is limited (Kittel, Brauhardt, & Hilbert, 2015;Lavagnino, Arnone, Cao, Soares, & Selvaraj, 2016;Van den Eynde et al, 2011;Voon, 2015;Wu et al, 2014Wu et al, , 2016Wu, Hartmann, Skunde, Herzog, & Friederich, 2013). A recent meta-analysis (Cury et al, 2020) showed alterations in working memory of individuals with BED, relative to obese people without the disorder however the effect size was small. For the other domains (inhibitory control, decision making and cognitive flexibility), no differences in performance were found between the two groups.…”

Depressive symptoms rather than executive functioning predict group cognitive behavioural therapy outcome in binge eating disorder

Executive functions play an important role in mediating self-control and selfregulation. It has been suggested that the inability to control eating in Binge Eating Disorder (BED) may indicate inefficiencies in executive functioning. This study investigated whether executive functioning predicted cognitive behavioural therapy outcome in BED while accounting for other possible predictors: depressive symptoms, interpersonal factors, eating disorder psychopathology, and self-esteem. Executive functioning and other predictors were assessed in 91 patients with BED by means of neuropsychological tests and questionnaires at baseline. Eating disorder (ED) symptoms were assessed during treatment at variable time points. Potential predictor variables were investigated using multivariate Cox regression models. Recovery was defined by means of two different indicators based on the Eating Disorder Examination-Questionnaire: (a) showing a 50% reduction in baseline symptom ED severity and/or reaching the clinical significance cutoff ; and (b) achieving abstinence of objective binge eating. Severity of depressive symptoms was a significant predictor for outcome on both indicators. Patients with no or mild depressive symptoms recovered faster (i.e., 50% reduction in ED symptoms and abstinence of objective binge eating) than those with severe depressive symptoms, which is in line with previous studies. Executive functioning was not related to treatment outcome in this study.

Recurring episodes of excessive food intake in binge eating disorder can be understood through the lens of behavioral control systems: patients repeat maladaptive behaviors against their explicit intent. Self-report measures show enhanced impulsivity and compulsivity in binge eating (BE) but are agnostic as to the processes that might lead to impulsive and compulsive behavior in the moment. Task-based neurocognitive investigations can tap into those processes. In this systematic review, we synthesize neurocognitive research on behavioral impulsivity and compulsivity in BE in humans and animals, published between 2010-2020.Findings on impulsivity are heterogeneous. Findings on compulsivity are sparse but comparatively consistent, indicating an imbalance of goal-directed and habitual control as well as deficits in reversal learning. We urge researchers to address heterogeneity related to mood states and the temporal dynamics of symptoms, to systematically differentiate contributions of body weight and BE, and to ascertain the validity and reliability of tasks. Moreover, we propose to further scrutinize the compulsivity findings to unravel the computational mechanisms of a potential reinforcement learning deficit.
