INTRODUCTION: There may be shared neuropsychological dysfunctions in ADHD and obesity. This study tested a neuropsychological model of ADHD (reward/executive dysfunctioning) in individuals with obesity. Furthermore, the association between co-morbid binge eating and reward/executive dysfunction was explored.
METHODS: Reward/executive dysfunctioning was assessed using both neuropsychological measures and questionnaires in individuals (aged 17-68) with obesity (N = 39; mean BMI = 39.70) and normal weight (N = 25; mean BMI = 22.94).
RESULTS: No significant differences emerged between individuals with and without obesity on the outcome measures. However, individuals with obesity and binge eating showed significantly more self-reported delay discounting and inattention than those individuals with obesity but without binge eating. When controlling for inattention, this difference in delay discounting was no longer significant.
DISCUSSION: Not obesity alone but obesity with binge eating was specifically associated with a mechanism often reported in ADHD, namely delay discounting. However, this effect may be more driven by inattention.
