Psychopathology and treatment of night eating syndrome: a review.

The article reviews the international literature about psychopathological aspects and treatments of Night Eating Syndrome (NES). Studies were found using Medline; data from recent international books and conferences about ED are included, but single case descriptions are not included in the study. NES seems to be consistently related to mood disorders and anxiety. There is a low overlap between other eating disorders, including binge eating disorder (BED), and NES. The relationship between the syndrome and substance abuse is unclear and needs further study. Sleep architecture seems not to be severely altered among those with NES. A limited number of treatment studies for NES have been published or presented. Most of the literature focuses on pharmacological treatment, with fewer psychotherapeutic approaches reported at this time. Larger, multi-site treatment studies would serve to confirm the findings of this first wave of clinical trials.
