Inhibitory control and ability to maintain response in obesity and binge eating disorder

Abstract

The aim of this study was to analyse the inhibitory control and the ability to maintain response in obese patients with and without Binge Eating Disorder (BED), compared to normalweight subjects. A total of 114 participants comprised three different groups (obese with BED, obese without BED and normal-weight) completed the Frontal Assessment Battery, the Stroop Neuropsychological Screening Test and the Wisconsin Card Sorting Test. The results showed differences between the obese groups and normal-weight group, to inhibitory control. There were also differences between the two obese groups in the ability to maintain the response. These results suggest that low inhibitory control, characterizes obesity and the difficulties to maintain the response, characterizes the binge eating disorder.
