Summary
Eating disorders (ED) like anorexia nervosa and bulimia nervosa are increasingly common and often involve significant sleep disturbances. This review examines sleep patterns in ED patients compared to controls.
Area of Science:
- Psychiatry
- Sleep Medicine
- Clinical Psychology
Context:
- Eating disorders (ED) prevalence has risen dramatically in Western societies over the past 30 years.
- Anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (ED-NOS) are major syndromes associated with high morbidity and life-threatening complications.
- Sleep disturbances are a predominant symptom across various eating disorders.
Purpose:
- To present diagnostic criteria for eating disorders.
- To review sleep structure and research on sleep patterns in individuals with AN, BN, and binge eating disorder (BED).
- To examine night eating syndrome (NES) as a condition combining eating and sleeping disorders.
Summary:
- The article reviews research on sleep patterns in patients with AN, BN, BED, and NES, comparing their sleep-wake characteristics to control groups.
- Different methodologies, including polysomnography, actigraphy, and self-report questionnaires, have been employed to study sleep in these populations.
- Characteristic sleep-wake patterns for each disorder are described, alongside potential explanations for discrepancies between subjective and objective sleep experiences.
Impact:
- Provides a comprehensive overview of the intricate relationship between eating disorders and sleep disturbances.
- Highlights the need for further research into the mechanisms underlying sleep abnormalities in ED.
- Informs clinical practice regarding the assessment and management of sleep issues in individuals with eating disorders.
