Summary

People who suffer from binge eating disorder experience recurrent episodes of binge eating.During these episodes, they consume an unusually large amount of food in a short amount of time and experience loss of control over eating. However, why such binge eating episodes occur is still largely unknown. This makes it difficult to develop targeted treatments. In this project, the experimenters are investigating the brain mechanisms that give rise to the disorder. They hypothesize that the binge eating episodes are due to an increased variability in reward processing, which they will assess repeatedly over days. They will test this hypothesis using mathematical models based on behavioural and MRI measurements that are related to the processing of rewards.

Criteria includes occurrence on average, at least 2 days a week for 6 months. The binge eating is not associated with the regular use of inappropriate compensatory behavior (i.e. purging, excessive exercise, etc.) and does not co-occur exclusively with BULIMIA NERVOSA or ANOREXIA NERVOSA. (From DSM-IV, 1994)

An eating disorder that is characterized by a cycle of binge eating (BULIMIA or bingeing) followed by inappropriate acts (purging) to avert weight gain. Purging methods often include self-induced VOMITING, use of LAXATIVES or DIURETICS, excessive exercise, and FASTING.

Little or no appetite for breakfast due to eating more food after dinner than during the meal and eating more than half of daily food intake after dinner hour.

This disorder occurs most frequently in adolescent females. (APA, Thesaurus of Psychological Index Terms, 1994)
