Night eating in bipolar disorder.

Objective: Night eating syndrome (NES) involves reduced feeding during the day and evening hyperphagia sometimes accompanied by frequent nocturnal awakenings with conscious episodes of compulsive ingestion of food. Previously, NES has not been evaluated in bipolar disorder (BD). The objective of this study was to identify NES in euthymic BD patients.

Sleep and circadian alterations in people at risk for bipolar disorder: A systematic review.

Background: Sleep and circadian abnormalities have been mostly demonstrated in bipolar patients. However, it is not clear whether these alterations are present in population at high risk for bipolar disorder (BD), indicating a possible risk factor for this condition.

Objective: This systematic review aims to define current evidence about sleep and rhythm alterations in people at risk for BD and to evaluate sleep and circadian disorders as risk factor for BD.
