TLDR
BN but not BED patients differed from their respective control groups concerning the "stopping" component of impulsivity, which may contribute to the behavioral distinctions in binge-eating behavior between BN and BED.Abstract:
Objective
To investigate neuropsychological mechanisms of impulsivity in patients with bulimia nervosa (BN) and binge-eating disorder (BED).
Method
Nineteen BN patients and 31 age- and body-mass-index (BMI)-matched healthy controls (c-BN) as well as 54 overweight and obese BED patients and 43 age- and BMI-matched healthy controls (c-BED) were investigated using an inhibitory control task (stop signal task, SST) and a decision-making under risk task (game of dice task, GDT).
Results
Compared to c-BN, BN patients demonstrated significant greater stop signal reaction times in the SST, but no differences for the frequency of risky decisions in the GDT. BED patients did not differ from c-BED in the SST or the GDT.
Discussion
BN but not BED patients differed from their respective control groups concerning the “stopping” component of impulsivity. These differences in motor inhibition may contribute to the behavioral distinctions in binge-eating behavior between BN and BED. © 2013 Wiley Periodicals, Inc.

TL;DR: Multiple biopsychosocial influences are implicated in eating disorders and/or disordered eating symptoms and several can now be considered established risk factors.

Inhibitory control in obesity and binge eating disorder: A systematic review and meta-analysis of neurocognitive and neuroimaging studies
TL;DR: It is found that inhibitory control is significantly impaired in obese adults and children compared to individuals with body weight within a healthy range and a potential target for clinical interventions.
Journal ArticleDOI
The neurobiological basis of binge-eating disorder.
TL;DR: Overall, the current evidence suggests that BED may be related to maladaptation of the corticostriatal circuitry regulating motivation and impulse control similar to that found in other impulsive/compulsive disorders.

Personality traits and obesity: a systematic review.
TL;DR: The results of the present review suggest that, within the context of therapeutic weight reduction measures, it is meaningful to identify subgroups of patients for whom specific treatment options need to be developed, such as measures for strengthening self‐control skills.

A systematic review of the relationship between eating, weight and inhibitory control using the stop signal task.
TL;DR: Altered reactive inhibitory control is related to some maladaptive eating behaviours, and hence may provide a therapeutic target for behavioural manipulations and/or neuromodulation in clinical and non-clinical populations.

TL;DR: Eating disorders, although relatively uncommon, represent a public health concern because they are frequently associated with other psychopathology and role impairment, and are frequently under-treated.

TL;DR: The evidence supporting the existence of two dimensions of impulsivity, reflecting one of the primary dimensions of Gray's personality theory, and rash-spontaneous impulsiveness are reviewed in relation to substance misuse and binge eating.

TL;DR: In this paper, the authors conducted a longitudinal assessment of mortality over 8 to 25 years in 1,885 individuals with anorexia, bulimia, or eating disorder not otherwise specified who presented for treatment at a specialized eating disorders clinic in an academic medical center.

TL;DR: Both eating disorder and obesity treatments seem to be beneficial in BED, however, it is recommended today that treatment should first be directed at the disordered eating and associated psychopathology.

TL;DR: Results show that Korsakoff patients are strongly impaired in this explicit decision-making task and that these disturbances are correlated with specific executive functions.
