Nocturnal eating syndrome in adults.
ABSTRACT Ten adult subjects were referred to our sleep disorders center complaining of difficulty in maintaining sleep due to frequent and recurrent awakenings to eat or drink. All patients manifested more than one episode per night, characterized by compulsive food seeking and a return to sleep only after adequate food intake. Food-seeking drive was described as an urgent abnormal need to swallow food and was associated with an absence of real hunger. Six subjects showed an elective nighttime intake of carbohydrates, and in all cases only edible substances were injected. The patients were always fully awake during the episodes and could clearly recall them in the morning. Polysomnographic investigation showed low levels of sleep efficiency, a high number of awakenings and a strict relation between nocturnal eating episodes and nonrapid eye movement (NREM) sleep. The average length of each episode was 3.5 minutes. The "eating latency", that is the interval between awakening and chewing start, was shorter than 30 seconds in 50% of the episodes. No medical, hormonal or neurological disorders were found during clinical and laboratory investigations. Body mass index was abnormally high in six patients. Anorexia nervosa and bulimia were carefully excluded. Various psychiatric disturbances were found in nine subjects, who were nevertheless well-functioning adults. Concurrent dyssomniac disorders, such as narcolepsy or periodic leg movements occasionally associated with restless legs syndrome, were diagnosed in five patients.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT: ntroduction: The purpose of this study is to investigate the prevalence and the clinical features of night eating syndrome (NES) in patients with depression and anxiety disorders. Method: The study was conducted at Bakırköy State Hospital for Mental Health and Neurological Disorders. Three-hundred out-patients who had major depression (MD), panic disorders (PD), general anxiety disorders (GAD) and obsessive-compulsive disorders (OCD) participated in the study. The semi-structured socio-demographic form, the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Night Eating Questionnaire, and NES Evaluation Questionnaire were implemented. Results: In our sample, the prevalence of the NES was 15.7% (n=47). NES frequency was significantly higher in the patients diagnosed with major depression (MD 22%, GAB 7.8%, OCD 12.5%, PD 14%). Smoking, presence of past suicide attempts, rates of antipsychotic drugs use, and average scores of body mass index (BMI) were significantly higher in the patients who had NES. In this sample, depression, BMI, and smoking were found to be determinants of NES. Conclusion: This study shows that NES may be frequently observed in patients admitted to psychiatric clinics, especially in those with major depression. Evaluation of NES in psychiatric patients may help the treatment of the primary psychopathology and prevent the adverse effects, like weight gain, which may reduce the quality of life.Noropsikiyatri Arsivi 12/2014; 2014(4):368-375.

ABSTRACT: Night Eating Syndrome (NES) is a unique disorder characterized by a delayed pattern of food intake in which recurrent episodes of nocturnal eating and/or excessive food consumption occur after the evening meal. NES is a clinically important disorder due to its relationship to obesity, its association with other psychiatric disorders, and problems concerning sleep. However, NES often goes unrecognized by both health professionals and patients. The lack of knowledge regarding NES in clinical settings may lead to inadequate diagnoses and inappropriate treatment approaches. Therefore, the proper diagnosis of NES is the most important issue when identifying NES and providing treatment for this disorder. Clinical assessment tools such as the Night Eating Questionnaire may help health professionals working with populations vulnerable to NES. Although NES treatment studies are still in their infancy, antidepressant treatments and psychological therapies can be used for optimal management of patients with NES. Other treatment options such as melatonergic medications, light therapy, and the anticonvulsant topiramate also hold promise as future treatment options. The purpose of this review is to provide a summary of NES, including its diagnosis, comorbidities, and treatment approaches. Possible challenges addressing patients with NES and management options are also discussed.Neuropsychiatric Disease and Treatment 03/2015; 11:751-760. DOI:10.2147/NDT.S70312 · 2.15 Impact Factor

ABSTRACT: Objective: Nocturnal eating behavior is shared by patients affected by a parasomnia, sleep-related eating disorder (SRED), and several eating disorders such as night eating syndrome (NES) and binge-eating disorder (BED); however, the differential clinical features of these patients have been poorly studied, with persisting difficulties in defining the borders between these pathologies. The aim of this study was to evaluate polysomnographic and personality characteristics of nocturnal eaters to further differentiate the syndromes. Methods: During a period of six months, consecutive patients complaining of nocturnal eating were asked to participate to the study. Twenty-four patients who were found to eat during the polysomnographic recording (PSG) study, and gender-matched control subjects were included. All subjects underwent a fullnight video-PSG study and a psychometric assessment including the Eating Disorder Inventory (EDI-2), the self-rating Bulimic Investigatory Test–Edinburgh (BITE), the Temperament and Character Inventory (TCI), and the Barratt Impulsivity Scale (BIS). Results: Nocturnal eaters showed a mild reduction in sleep efficiency and duration due to a moderate sleep fragmentation, whereas the percentage of each sleep stage was not significantly affected. Nocturnal eaters scored higher at many subscales of the EDI-2, at the BITE symptoms subscale, and at the BIS attentional impulsivity subscale. Conclusion: The psychological characteristics found in our patients with NES seem to be typical for patients affected by eating disorders, and support the hypothesis that the nocturnal behavior of these individuals is due to an eating disorder; however, specific traits also allow differentiation of NES from BED.Sleep Medicine 05/2015; · 3.10 Impact Factor
