| Abstract (Italian): |
Binge eating disorder (BED) is characterized by uncontrolled consumption of a large amount of food in a brief period of time. A large body of evidence has shown that BED can be a chronic condition associated with elevated psychiatric comorbidity, including depression and anxiety, and compulsive behavior. In this study we used an animal model of BED in which binge eating behavior was induced in female rats by providing limited access to high fat diet (margarine) to investigate the emotional traits of bingeing animals before and after the binge-like consumption of margarine. Using the plus maze test to disclose a potential anxious phenotype, we found that bingeing rats are much more anxious before the access to margarine, and that this condition is significantly reduced after its consumption. Conversely, no difference was detected between bingeing rats in the marble burying test before and after access to margarine. Yet, the number of marbles buried by bingeing rats before margarine consumption was significantly higher than control groups thus suggesting a compulsive-like trait. In the forced swimming test, bingeing rats showed a decrease in depression-like behavior after the consumption of margarine. Altogether, our findings demonstrate the occurrence of an altered emotional state in female rats showing binge eating behavior. [ABSTRACT FROM AUTHOR] |
