Vasiliu O. Current evidence and future perspectives in the exploration of sleep-related eating disorder-a systematic literature review. Front Psychiatry 2024; 15:1393337.

Abstract
Sleep-related eating disorder (SRED) is a non-REM parasomnia with potentially significant negative effects on general health (dangerous activities during night eating episodes, obesity, or metabolic syndrome, for example). Although the history of SRED encompasses more than six decades, public awareness and even the awareness of the mental health specialists of this disorder is very limited, a phenomenon that hinders the development of research in this field. Therefore, a systematic review based on PRISMA 2020 guidelines explored the available evidence for SRED found in four electronic databases (PubMed, Cochrane Collaboration, Google Scholar, and Clarivate/Web of Science). A number of 94 primary and secondary reports were retrieved, investigating aspects regarding the risk factors, epidemiology, clinical data and differential diagnosis, epidemiology, structured evaluation, and treatment of SRED. Based on the results of these reports, Z-drugs, but also certain benzodiazepines, antidepressants, antipsychotics, and psychostimulants may trigger the onset of SRED. Psychiatric and neurologic disorders have also been associated with SRED, either as risk factors or comorbid conditions. Cerebral glucose metabolism dysfunctions, neurotransmitter dysfunctions, and genetic factors have been invoked as pathogenetic contributors. Structured assessment of SRED is possible, but there is a dearth of instruments dedicated to this purpose. Data on the prevalence and treatment of SRED exist, but good-quality epidemiological studies and clinical trials are still missing. In conclusion, future research is expected to address the shortcomings of SRED exploration by creating the conditions for better quality and larger group clinical research. The need for such investigation is granted by the importance of this pathology and its negative functional consequences.

Abstract
Sleep-related eating disorder is a non-rapid-eye movement parasomnia typified by recurrent episodes of eating/drinking following arousals, with associated partial/complete amnesia. Adverse health consequences and quality of life impairments are common. The condition can be idiopathic but most often accompanies unrecognized/untreated comorbid sleep disorders and/or is induced by psychoactive medications. As such, management consists of addressing comorbidities and removing potentially offending medications. While a thorough clinical history is often sufficient, additional sleep testing may help identify coexisting sleep disorders and/or other phenomena that may cause arousals. Limited data suggest benefit from topiramate and other medications in idiopathic or otherwise refractory cases.

Abstract
In sleep-related dissociative disorders, phenomena of the psychiatrically defined dissociative disorders emerge during the sleep period. They occur during sustained wakefulness, either in the transition to sleep or following an awakening from sleep. Behaviors during episodes vary widely, and can result in injury to self or others. Daytime dissociative episodes and a background of trauma are almost always present; there is typically major co-existing psychopathology. Diagnosis is based on both clinical history and polysomnography; differential diagnosis primarily involves other parasomnias and nocturnal seizures. Information available about treatment is limited; in a few reported cases, psychological interventions have proven effective.

Abstract
Background Nocturnal eating behavior in patients with sleep-related eating disorder (SRED) is difficult to control and can become chronic, causing weight gain and psychological distress. Here, we report a case of SRED comorbid with major depressive disorder successfully treated by switching from brotizolam to suvorexant, that is, from a benzodiazepine to an orexin receptor antagonist. Case Presentation A 25-year-old woman complained of night snacking with partial/complete amnesia and sleepwalking for 1 year. She had a diagnosis of major depressive disorder at age 20 and was on paroxetine and brotizolam for depression and insomnia. At 24 years of age, she experienced her second depressive episode, then her amnestic nocturnal eating became prominent. Even after improvement in depressive symptoms, she experienced uncontrollable nocturnal eating episodes every 2 days, resulting in weight gain of over 10 kg. After a partial amnestic eating episode following an awakening from stage N2 sleep was confirmed through video polysomnography, she was diagnosed with SRED. Considering her strong desire to resolve involuntary eating, we instructed her to discontinue brotizolam and start suvorexant. Subsequently, her nocturnal eating completely disappeared. She experienced rebound insomnia, which improved within 1 month. She was then continued on 10 mg of suvorexant and has not experienced nocturnal eating for 2 years. Conclusion This case highlights the importance of discontinuing benzodiazepines in the treatment of SRED, but also suggests the potential benefit of orexin receptor antagonists in the treatment of SRED. The efficacy of orexin receptor antagonists in idiopathic SRED should be tested in future studies.

Abstract
Background Sleep-related eating disorder (SRED) consists of recurrent episodes of uncontrolled, involuntary eating and drinking 1-3 h after falling asleep with partial or full unconsciousness. This condition is diagnosed based on interviews with the patients affected and the diagnostic criteria of the International Classification of Sleep Disorders. However, polysomnography (PSG) is not necessary to confirm this disease. This systematic review aims to evaluate the findings of PSG in SRED patients. Methods For this systematic review, PubMed, Embase, and Scopus databases were searched in February 2023, which resulted in 219 records. After removing duplicates, the articles that included the presentation of PSG results of SRED patients in English were selected. In addition, only original studies were considered. The risk of bias by using case reports and descriptive studies was assessed using the Joanna Briggs Institute critical appraisal tools and the Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool. Furthermore, a case report of a 66-year-old woman with SRED was included. Results A total of 15 papers were selected for further analysis, of which 7 were descriptive studies, 6 were case reports, and 2 were observational studies. The risk of bias in the majority of the studies was moderate or high. Unexpectedly, if the eating episode occurred during PSG, in most cases it was not observed during deep sleep (the N3 sleep stage). Moreover, studies did not report significant deviations in the sleep parameters measured using PSG. Among SRED patients, the prevalence of sleepwalking was much higher than the general population. Our case report presented a potentially life-threatening episode of holding an apple in the mouth that might result in choking, which was captured using PSG. Conclusion Polysomnography is not necessary for the diagnosis of SRED. However, it could facilitate the diagnosis and differentiation of SRED from other eating disorders. PSG also has limitations in capturing eating episodes and in addition, its cost effectiveness should be considered during the diagnostic process. More studies into the pathophysiology of SRED are needed because classifying SRED as non-rapid eye movement parasomnias can be inappropriate as it does not always occur during deep sleep.

Abstract
Non-rapid eye movement (NREM) sleep parasomnias are recurrent abnormal behaviors emerging as incomplete arousals out of NREM sleep. Mounting evidence on NREM sleep parasomnias calls for an update of clinical and therapeutical strategies. In the current review, we summarize the state of the art and provide the necessary background to stimulate a critical revision of diagnostic criteria of disorders of arousal (DoA), the most common NREM sleep parasomnia. In particular, we highlight the poor sensitivity of the diagnostic items related to amnesia and absence of conscious experiences during DoA episodes, encourage the role of video-polysomnography and home-video recordings in the diagnostic and treatment work-up, and suggest three levels of diagnostic certainty based on clinical and objective findings. Furthermore, we highlight current gaps of knowledge that prevent the definition of standard guidelines and future research avenues.

Abstract
AIM To establish patterns or themes of dreams and dreamlike mentation content reported in all forms of non-rapid eye movement (NREM) parasomnias and to identify gaps in the current understanding of this topic. METHODS A scoping review of available evidence on dreams and dreamlike mentation in NREM parasomnias was conducted in accordance with the PRISMA-ScR guidelines. We searched peer-reviewed literature using Google Scholar, PubMed, Ovid (Embase), Ovid Medline®, Global Health, and APA Psych Info. The Mixed Method Appraisal Tool (MMAT) was used to appraise the quality of selected articles. RESULTS The final analysis included 16 studies. All of the studies were from high-income countries. The studies reported on dreams and dreamlike mentation in NREM parasomnias, but there was scarcity of literature for sexsomnia, sleep-related eating disorder, and confusional arousal. All of the studies had the highest quality as shown by the MMAT (76%-100%). Emotions such as apprehension and misfortune were associated with sleepwalking and sleep terrors. CONCLUSION Sleep studies involving collection of dream content immediately following NREM parasomnia could significantly minimize reporting bias and improve dream data quality.

Abstract
Parasomnias are undesirable events that occur during sleep. They can be classified into rapid eye movement parasomnias and non-rapid eye movement parasomnias. Those who experience parasomnias may be anxious about travel for many reasons, including the occurrence of unwanted events during the trip, increased exposure to environmental trigger factors, and the propensity for harm to occur due to unfamiliar surroundings while travelling. There is a paucity of literature examining this area. This review summarizes the relevant literature and the clinical experience of the authors to compile clinical practice recommendations. The clinical features of parasomnias and how they relate to trans-meridian and long-distance travel are described. Triggers for non-rapid eye movement parasomnias, particularly the use of sedative hypnotic drugs, alcohol, drug withdrawal, sleep deprivation, emotional stress and environmental stimulations, are described. Management of parasomnias whilst travelling is reviewed, with a particular focus on trigger minimalization. The role for clonazepam and melatonin is outlined. At the pre-travel health consultation, the physician is strongly advised to screen the traveller for co-morbid sleep conditions, which exacerbate parasomnias. Areas for further research are explored, including the extent to which these sleep disorders impact on the travel experience.

Abstract
Disorders of arousal (DOA) is an umbrella term initially covering classical sleepwalking, sleep terrors, and confusional arousals, and now including a wider spectrum of specialised forms of non rapid eye movement (non REM) parasomnias such as sexsomnia, sleep-related eating disorder, and sleep-related choking syndrome. Growing evidence has shown that DOA are not restricted to children but are also prevalent in adults (2%-4% of the adult population). While DOA run in family, genetics studies remain scarce and inconclusive. In addition to the risk of injury on themselves and others (including sexual assaults in sexsomnia), adults with DOA frequently suffer from excessive daytime sleepiness, pain, and altered quality of life. The widespread view of DOA as automatic and amnesiac behaviours has now been challenged by subjective (dream reports) and objective (dream-enacting behaviours documented on video-polysomnography) observations, suggesting that sleepwalkers are 'dream walking' during their episodes. Behavioural, experiential, cognitive, and brain (scalp electroencephalography [EEG], stereo-EEG, high density-EEG, functional brain imaging) data converge in showing a dissociated pattern during the episodes. This dissociated pattern resembles the new concept of local arousal with a wake-like activation in motor and limbic regions and a preserved (or even increased) sleep intensity over a frontoparietal network. EEG and behavioural criteria supporting the DOA diagnosis with high sensitivity and specificity are now available. However, treatment is still based on controlling priming and precipitating factors, as well as on clinicians' personal experience with sedative drugs. Placebo-controlled trials are needed to improve patients' treatment. DOA deserve more attention from sleep researchers and clinicians.

Abstract
Parasomnias are involuntary behaviors or subjective experiences during sleep. Our objective was to review existing information on the presence of parasomnias in patients with addictions or during treatment for addictions. Information about parasomnias related to rapid-eye-movement (REM) and non-REM sleep in patients with addictions, while using substances or in abstinence, was reviewed. A systematic search of published articles reporting parasomnias as a consequence of drug use or abuse was conducted in the PubMed and SciELO databases. The search for the studies was performed in three phases: (1) by title, (2) by abstract, and (3) by complete text. The search was performed independently by two researchers, who then compared their results from each screening phase. Seventeen articles were found. The consumption of alcohol was reported in association with arousal disorders, such as sexsomnia and sleep-related eating disorder; and REM sleep behavior disorder was reported during alcohol withdrawal. Cocaine abuse was associated with REM sleep behavior disorder with drug consumption dream content. Overall, we found that several types of parasomnias were very frequent in patients with addictions. To avoid accidents in bedroom, legal problems, and improve evolution and prognosis; must be mandatory to include security measures related to sleep period; avoid pharmacological therapy described as potential trigger factor; improve sleep hygiene; and give pharmacological and behavioral treatments for patients with these comorbid sleep disorders.

Abstract
STUDY OBJECTIVES To assess the frequency, determinants and clinical impact of clinical NREM and REM parasomnias in adult patients with narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia (IH) compared to healthy controls. METHODS Familial and past and current personal parasomnias were assessed by questionnaire and medical interviews in 710 patients (220 NT1, 199 NT2, and 221 IH) and 595 healthy controls. RESULTS Except for sleep-related eating disorder (SRED), current NREM parasomnias were rare in all patient groups and controls. SRED was more frequent in NT1 patients (7.9%, vs. 1.8% in NT2 patients, 2.1% in IH patients and 1% in controls) and associated with disrupted nighttime sleep (odds ratio [OR] = 3.9) and nocturnal eating in full awareness (OR = 6.9) but not with sex. Clinical REM sleep behavior disorder (RBD) was more frequent in NT1 patients (41.4%, half being violent) than in NT2 patients (13.2%) and affected men more often than women (OR = 2.4). It was associated with disrupted nighttime sleep, depressive symptoms and antidepressant use. Frequent (>1/week) nightmares were reported by 39% of patients with NT1, 29% with NT2 and 27.8% with IH (vs. 8.3% in controls) and were associated with depressive symptoms in narcolepsy. No parasomnia (except sleep-related hallucinations) worsened daytime sleepiness. CONCLUSIONS In patients with central disorders of hypersomnolence, comorbid NREM parasomnias (except SRED) are rare and do not worsen sleepiness. In contrast, REM parasomnias are prevalent (especially in NT1) and associated with male sex, disrupted nighttime sleep, depressive symptoms and antidepressant use.

Abstract
Rapid eye movement (REM) behavior disorder (RBD) is characterized by loss of skeletal muscle atonia that can lead to dream enactment. This condition can cause harm to patients and their bed partners if appropriate safety measures are not ensured. This condition is often the initial presenting symptom in a group of complex neurodegenerative processes. Definitive diagnosis requires a thorough history and an in-laboratory polysomnogram to look for evidence of REM sleep without atonia. Treatment options are limited but consist of sleep safety measures and pharmacotherapy. Patients diagnosed with idiopathic RBD associated with alpha-synucleinopathy are likely to have progression of disease.

Methods A literature search on PubMed's MeSH search feature, CINAHL, and SciFinder was performed using search terms "Zolpidem," "Feeding and Eating Disorders/chemically induced," "Dyssomnias," "sleep eating disorder," and "sleep-related eating disorder." Three reviewers examined all English and Spanish citations and extracted pertinent information. A narrative synthesis of the evidence was prepared. Results We identified 40 case reports of which 65% were female, and the mean age was 53 years. SRED onset was most commonly seen with daily zolpidem doses of 10 mg or higher (95% of patients). Prior medical history included obstructive sleep apnea (OSA) (35%), depression (32.5%), and restless leg syndrome (RLS) (25%). Even with controlled RLS and OSA, SRED developed in some patients. All patients had either partial or full amnesia with compulsive eating. Onset of SRED occurred as early as the first dose to after 9 years of use. SRED symptoms occurred nightly in 57.5% of patients. Discontinuation of zolpidem resolved SRED in all patients (n = 36). Conclusion SRED associated with zolpidem can occur with any dose, but was most common with higher doses of zolpidem. Therefore, prescribers should initiate lower doses of zolpidem. Interestingly, many patients had underlying disorders known to affect sleep (RLS, OSA, depression). Although it is recommended to control these underlying disorders prior to initiating zolpidem, SRED may still occur. Zolpidem discontinuation resolved all cases of SRED.

Abstract
Parasomnias are abnormal behaviors and/or experiences emanating from or associated with sleep typically manifesting as motor movements of varying semiology. We discuss mainly nonrapid eye movement sleep and related parasomnias in this article. Sleepwalking (SW), sleep terrors (ST), confusional arousals, and related disorders result from an incomplete dissociation of wakefulness from nonrapid eye movement (NREM) sleep. Conditions that provoke repeated cortical arousals, and/or promote sleep inertia, lead to NREM parasomnias by impairing normal arousal mechanisms. Changes in the cyclic alternating pattern, a biomarker of arousal instability in NREM sleep, are noted in sleepwalking disorders. Sleep-related eating disorder (SRED) is characterized by a disruption of the nocturnal fast with episodes of feeding after arousal from sleep. SRED is often associated with the use of sedative-hypnotic medications, in particular the widely prescribed benzodiazepine receptor agonists. Compelling evidence suggests that nocturnal eating may in some cases be another nonmotor manifestation of Restless Legs Syndrome (RLS). Initial management should focus upon decreasing the potential for sleep-related injury followed by treating comorbid sleep disorders and eliminating incriminating drugs. Sexsomnia is a subtype of disorders of arousal, where sexual behavior emerges from partial arousal from nonREM sleep. Overlap parasomnia disorders consist of abnormal sleep-related behavior both in nonREM and REM sleep. Status dissociatus is referred to as a breakdown of the sleep architecture where an admixture of various sleep state markers is seen without any specific demarcation. Benzodiazepine therapy can be effective in controlling SW, ST, and sexsomnia, but not SRED. Paroxetine has been reported to provide benefit in some cases of ST. Topiramate, pramipexole, and sertraline can be effective in SRED. Pharmacotherapy for other parasomnias continues to be less certain, necessitating further investigation. NREM parasomnias may resolve spontaneously but require a review of priming and predisposing factors.

Abstract
Nocturnal (night) eating syndrome and sleep-related eating disorder have common characteristics, but are considered to differ in their level of consciousness during eating behavior and recallability. To date, there have been no large population-based studies determining their similarities and differences. We conducted a cross-sectional web-based survey for Japanese young adults aged 19-25 years to identify factors associated with nocturnal eating behavior and sleep-related eating disorder-like behavior using Munich Parasomnia Screening and logistic regression. Of the 3347 participants, 160 (4.8%) reported experiencing nocturnal eating behavior and 73 (2.2%) reported experiencing sleep-related eating disorder-like behavior. Smoking (p < 0.05), use of hypnotic medications (p < 0.01), and previous and/or current sleepwalking (p < 0.001) were associated with both nocturnal eating behavior and sleep-related eating disorder-like behavior. A delayed sleep-wake schedule (p < 0.05) and sleep disturbance (p < 0.01) were associated with nocturnal eating behavior but not with sleep-related eating disorder-like behavior. Both nocturnal eating behavior and sleep-related eating disorder-like behavior had features consistent with eating disorders or parasomnias. Nocturnal eating behavior but not sleep-related eating disorder-like behavior was characterized by a sleep-awake phase delay, perhaps representing an underlying pathophysiology of nocturnal eating syndrome.

Abstract
Abstract
Study Objectives
Sleep-related eating disorder (SRED) is a parasomnia characterized by partial arousals from sleep with compulsive consumption of food with impaired level of awareness and memory for the event. Small case series’ have demonstrated efficacy of topiramate in SRED. We conducted a placebo-controlled randomized clinical trial of topiramate to assess efficacy in SRED.
Methods
Thirty-four participants with an ICSD-2/ICSD-3 diagnosis of SRED with >6 months of symptoms and ≥3 sleep-related eating episodes per week were randomized to placebo or topiramate with flexible dosing to a maximum dosage of 300 mg for 13 weeks. Primary outcomes were percentage of nights with eating and Clinician Global Impression-Improvement (CGI-I). Intention-to-treat last observation carried forward (ITT LOCF) analysis was conducted.
Results
Mean age was 39.5 years, 74% were female, with mean duration of sleep-related eating of 13.7 years. SRED symptoms were significantly reduced with topiramate (74.7% to 33.2% nights/week; n = 15) compared to placebo (77.0% to 57.4%; n = 17) (p = 0.035). There were significantly more CGI-I responders on topiramate (71%) than placebo (27%) (p = 0.016). Level of wakefulness (r = −0.49) and memory for nighttime eating (r = −0.58) at baseline predicted topiramate response. The topiramate group lost significantly more weight than the placebo group (−8.5 lbs vs. +1.0 lbs, p = 0.001). The most common side effects were paresthesias and cognitive dysfunction.
Conclusions
This first randomized controlled trial demonstrating efficacy for treatment of SRED supports preliminary data on the use of topiramate for SRED. Side effects were prominent for topiramate. Limitations include a small sample size and a high drop-out rate in both study groups.

Abstract
Introduction: Night Eating Syndrome (NES) refers to an abnormal eating behavior which presents as evening hyperphagia consuming >25% calorie intake and/or nocturnal awaking with food ingestion which occurs ≥2 times per week. Although the syndrome has been described more than seven decades ago, the literature has been growing slowly on its etiology, diagnosis, and treatment. Areas covered: The proposed treatment options for NES are all at a case-study level. Moreover, our understanding of its etiology, comorbidities, and diagnosis is still premature. We performed a literature review in Medline/PubMed to identify all the studies proposing a management plan for NES and summarized all the existing data on its diagnosis and treatment. Expert opinion: To date, none of the proposed treatment options for NES have been promising and long-term data on its efficacy is lacking. The slow growth of evidence on this debilitating but underreported condition may be due to unawareness among clinicians, under-reporting by patients, and unrecognized diagnostic criteria. Objective screening of symptoms during office visits especially for patients at a high-risk for NES will identify more patients suffering from the syndrome.

Abstract
ABSTRACT We report two cases of adult males with sleep-related eating disorder (SRED), with durations of 3 and 7 years, and without associated psychiatric history. In both cases, the use of low-dose (25 mg) sertraline taken at bedtime resulted in immediate, full and sustained resolution of symptoms at the latest follow-ups. The sertraline efficacy was of particular benefit for the patient reported on in case 2 who was a commercial airline pilot subjected to a highly restricted list of Federal Aviation Administration-approved medications. Risk factors for SRED included smoking cessation and work-related stress in case 1, and a history of sleepwalking and work-related circadian disruptions and partial sleep deprivations in case 2. Sertraline therapy of SRED is considered within a review of all current pharmacologic therapies of SRED.

Abstract
Background Sleep-related eating disorder is characterized by parasomnia with recurrent episodes of nocturnal eating or drinking during the main sleep period. Several drugs, including atypical antipsychotics, induce sleep-related eating disorder. However, aripiprazole has not previously been associated with sleep-related eating disorder. Case presentation A 41-year-old Japanese man visited our clinic complaining of depression. The patient was treated with sertraline, which was titrated up to 100 mg for 4 weeks. A sleep inducer and an anxiolytic were coadministered. His depressive mood slightly improved, but it continued for an additional 4 months. Subsequently, aripiprazole (3 mg) was added as an adjunctive therapy. After 3 weeks, the patient’s mother found that the patient woke up and ate food at night. The next morning, the patient was amnesic for this event, felt full, and wondered why the bags of food were empty. This episode lasted for 2 days. The patient gained 5 kg during these 3 weeks. After the aripiprazole dose was reduced to 1.5 mg, the patient’s nocturnal eating episodes rapidly and completely disappeared. Conclusions To the best of our knowledge, this is first report of sleep-related eating disorder induced by aripiprazole, and it indicates that this disorder should be considered a possible side effect of aripiprazole. Although aripiprazole is used mainly in patients with schizophrenia, its recently documented use as an adjunctive therapy in patients with depression might induce hitherto unknown side effects.

Abstract
The circadian clock system is associated with feeding and mood. Patients with night eating syndrome (NES) delay their eating rhythm and their mood declines during the evening and night, manifesting as time-specific depression. Therefore, we hypothesized that the NES feeding pattern might cause time-specific depression. We established new NES model by restricted feeding with high-fat diet during the inactive period under normal-fat diet ad libitum. The FST (forced swimming test) immobility time in the NES model group was prolonged only after lights-on, corresponding to evening and early night for humans. We examined the effect of the NES feeding pattern on peripheral clocks using PER2::LUCIFERASE knock-in mice and an in vivo monitoring system. Caloric intake during the inactive period would shift the peripheral clock, and might be an important factor in causing the time-specific depression-like behavior. In the NES model group, synthesis of serotonin and norepinephrine were increased, but utilization and metabolism of these monoamines were decreased under stress. Desipramine shortened some mice’s FST immobility time in the NES model group. The present study suggests that the NES feeding pattern causes phase shift of peripheral clocks and malfunction of the monoamine system, which may contribute to the development of time-specific depression.

Abstract
Background Sleep-related eating may occur in the context of mental illness, sleep disorders, or psychopharmacological treatment. Frequently, sleep-related eating leads to severe weight gain and, so far, there are no treatment options for the condition. Case presentation We report the case of a 54-year-old white woman with depression, panic disorder, and sleep apnea under treatment with various antidepressants who developed severe sleep-related eating. Her sleep-related eating completely vanished after addition of agomelatine, it reoccurred after cessation of agomelatine, and vanished again after her re-exposure to another melatonergic drug, extended melatonin. Conclusions This case suggests that melatonergic drugs lead to relief from sleep-related eating, even when the condition occurs in the context of physical and mental disorders as well as psychopharmacological treatment.

Abstract
PURPOSE OF REVIEW This article reviews the spectrum of non-rapid eye movement (non-REM) sleep parasomnias, including sleepwalking, confusional arousals, and sleep terrors, which represent the range of phenotypic disorders of arousal from non-REM sleep that occurs in children and adults. RECENT FINDINGS The International Classification of Sleep Disorders, Third Edition (ICSD-3) classifies parasomnias according to the sleep stage they emerge from: REM, non-REM, or other. Demographics, clinical features, and diagnosis of non-REM parasomnias are reviewed in this article, and an up-to-date synopsis of guidelines for management strategies to assist in the treatment of these sleep disorders is provided. SUMMARY The non-REM parasomnias are most common in children and adolescents but may persist into adulthood. They can be distinguishable from REM parasomnias and nocturnal epilepsies, and, importantly, may lead to injury. Additionally, other parasomnias in this spectrum include sleep-related eating disorder and sexsomnia. Overlap parasomnia disorder includes one or more manifestations of a non-REM parasomnia seen in combination with REM sleep behavior disorder, representing an apparent erosion of the normally distinct stages of non-REM and REM sleep. A similar yet much more extreme dissociation of states underlies agrypnia excitata and status dissociatus, which represent rare, severe dissociations between non-REM, REM, and wake states resulting clinically in oneiric behaviors and severe derangement of normal polysomnographic wake and sleep stage characteristics. Management of non-REM and overlap parasomnias and state dissociation disorders include ensuring bedroom safety and prescription of clonazepam or hypnosis, in select cases, although in children and adolescents with noninjurious behaviors, non-REM parasomnias are often age-limited developmental disorders, which may ultimately remit by adulthood, and, in these cases, counseling and education alone may suffice. Timely and accurate recognition of the non-REM and overlap parasomnias is crucial to limiting potential patient injury.

Abstract
PURPOSE The aim of this study was to assess night eating syndrome (NES) in patients referred for polysomnography and its association with obstructive sleep apnea (OSA). We also assessed whether participants with OSA were more likely to get up and eat at night, and whether these behaviors were associated with the apnea-hypopnea sleep index (AHI). We additionally examined whether NES and OSA were associated with BMI, and assessed depressed mood among participants with NES or OSA. METHODS The Night Eating Diagnostic Questionnaire (NEDQ), Zung Depression Scale, and demographic and medical questionnaires were used to evaluate 84 qualified participants. Polysomnography was used to assess AHI, and therefore OSA. RESULTS Thirty individuals met full or sub-threshold NES (NES[St]) criteria, and 54 had no night eating (Normal). Eighty-nine percent of the sample had OSA with AHI≥5. Neither AHI nor BMI differed between NES(St) and Normal, F(1,82)=1.67, p=0.20 and F(1, 82)=2.2, p=0.14, respectively. Participants with NES(St) were, however, more likely than Normal to have depressed mood (mild, moderately, or severely depressed), χ2=4.47 p=0.03. There was a positive correlation between AHI and BMI, r=0.37, p=0.001. Those with OSA were not more likely to eat at night, F(1,82)=0.04, p=0.84, or get out of bed more often, F(1,13)=0.23, p=0.64, and there was no correlation between AHI and eating at night (r=-0.11, p=0.31). However, there was a positive correlation between AHI and the number of times participants got up out of bed (r=0.81, p<0.001). CONCLUSIONS We found that NES was not associated with BMI or AHI severity. The findings show that NES is primarily an eating disorder, rather than a sleep disorder, and that there is an association between NES and depressed mood.

Abstract
Sleep-related eating disorder (SRED) is a parasomnia characterised by recurrent episodes of eating after arousal from sleep, occurring in an unconscious and involuntary manner. It has been reported mainly in association with the use of psychotropic medications. This case report is of a patient diagnosed with a sleep-related eating disorder associated with amnesia in the postoperative period following bariatric surgery. Such eating episodes without awareness in postoperative period might have devastating results by disturbing compliance with suggested eating behaviours. Although it is a rare condition, SRED should be screened for among bariatric surgery candidates, and those affected should be directed for the appropriate treatment. Also whether SRED should be considered a contraindications to bariatric should be considered.

Abstract
PURPOSE The aim of this study was to ascertain the clinical characteristics of drug-induced sleep-related eating disorder (SRED). PATIENTS AND METHODS We retrospectively reviewed the medical records of 30 patients with primary SRED (without any comorbid sleep disorders and who were not taking any possible causative medications), and ten patients with drug-induced SRED (occurrence of SRED episodes after starting nightly medication of sedative drugs, which completely resolved after dose reduction or discontinuation of the sedatives). RESULTS All patients with drug-induced SRED took multiple types of sedatives, such as benzodiazepines or benzodiazepine receptor agonists. Clinical features of drug-induced SRED compared with primary SRED were as follows: higher mean age of onset (40 years old in drug-induced SRED vs 26 years old in primary SRED), significantly higher rate of patients who had total amnesia during most of their SRED episodes (75.0% vs 31.8%), significantly lower rate of comorbidity of night eating syndrome (0% vs 63.3%), and significantly lower rate of history of sleepwalking (10.0% vs 46.7%). Increased doses of benzodiazepine receptor agonists may be responsible for drug-induced SRED. CONCLUSION The clinical features of drug-induced SRED were different from those of primary SRED, possibly reflecting differences in the underlying mechanisms between these two categories of SREDs.

Abstract
OPINION STATEMENT Sleep-related eating disorder (SRED) is classified as an NREM-related parasomnia characterized by recurrent episodes of dysfunctional eating that occur after an arousal from the main sleep period with partial or complete amnesia for the event, resulting in weight gain from eating high calorie foods and causing various injuries due to consumption of inedible or toxic items. SRED can be idiopathic or commonly associated with other primary sleep disorders such as sleepwalking, restless legs syndrome (RLS), obstructive sleep apnea syndrome (OSAS), other clinical conditions, or use of sedative-hypnotic medications. First-line treatment of idiopathic SRED includes selective serotonin reuptake inhibitors (SSRIs) at mean dosages of 20 to 30 mg/day. Topiramate at 100-300 mg/day and clonazepam at 0.5-2.0 mg/day can be valid alternative options. SRED related to other parasomnias or sleep disturbances that cause sleep fragmentation benefit most from treatment of the associated sleep disorder. In particular, RLS-related SRED is best treated with dopamine agonists such as pramipexole, while sleepwalking-related SRED benefits from low-dose benzodiazepines such as clonazepam. Different kinds of drug associations have been proposed in a limited number of cases, especially in the past. We strongly recommend that all patients suffering from SRED should undergo consistent and regular follow-up about 2-3 times per year or otherwise according to the physician's judgment, in order to assess the evolution of symptom severity and frequency and re-evaluate treatment efficacy and any side effects that may arise.

Abstract
Sleep-related eating disorder (SRED) is a condition characterized by recurrent episodes of eating at the transition from night-time sleep to arousal. SRED patients describe eating in an out-of-control manner with preference for high-caloric foods and sometimes with inedible or toxic items. Level of consciousness during SRED episodes ranges from partial consciousness to dense unawareness typical of somnambulistic episodes. SRED is sometimes associated with psychotropic medication, in particular sedative hypnotics, and other sleep disorders, including parasomnias, narcolepsy, and restless legs syndrome. Night eating syndrome (NES) is another important condition in the disordered night-time eating spectrum showing hyperphagia episodes at full arousal from nocturnal sleep without accompanying amnesia. NES could be considered an abnormality in the circadian rhythm of meal timing with a normal circadian timing of sleep onset. The two conditions often overlap and possibly share a common pathophysiology. Studies have suggested that central nervous system serotonin modulation may lead to an effective treatment of NES, while the anti-seizure medication topiramate may be an effective SRED treatment.

Abstract
Restless legs syndrome (RLS) often presents with a primary complaint of sleep initiation difficulty with only ambiguous allusions to motor symptoms. This may result in the condition being misdiagnosed as a psychophysiological insomnia. Further, nocturnal eating is common in RLS and like the classic motor symptoms, patients will describe an inability to initiate sleep until their urge (to eat) is addressed. Restless nocturnal eating arises, intensifies, and subsides in parallel to motor symptoms. Once misdiagnosed as psychophysiological insomnia, RLS patients are frequently treated with benzodiazepine receptor agonists. The CNS actions of these sedating agents, suppression of memory and executive function, unleash predisposed amnestic behaviors. In the case of RLS this would be expected to include the inappropriate ambulatory and eating behaviors of sleep related eating disorder (SRED). The evidence and implications of a link between the restless eating of RLS and SRED is presented here.

Abstract
OBJECTIVES We aimed to describe a group of adults diagnosed with sleep-related eating disorder (SRED) at the Sleep Medicine Center of the Pontificia Universidad Catolica de Chile. METHODS We performed a descriptive study of 34 consecutive patients who met the criteria of the International Classification of Sleep Disorders for SRED evaluated during a 3-year period who did not have an eating disorder according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. All patients had a structured clinical interview performed by a sleep specialist and completed the Beck Depression Inventory (BDI). Polysomnography (PSG) was performed when clinically indicated for ruling out other sleep-related disorders (18 patients; 52.9%). Patients' demographic and clinical data, comorbidities, and treatment response also were analyzed. RESULTS Most patients were women (n=23; 67.6%). The average age at the time of diagnosis was 39±13.8 (17-67 years) and the latency since symptom onset was 8.3±8.8 years. Most patients had several episodes per night (average, 2.6±1.6; 1-8) and all except one patient had partial or total amnesia of these events (n=33; 97%). Comorbidities were frequent and included insomnia (n=20; 58.8%), restless legs syndrome (RLS) (n=16; 47%), sleep-disordered breathing (SDB) (n=9; 26%), psychiatric disorders (n=13; 38.2%), and overweight or obesity (n=14; 41.1%). Most patients were hypnotic users (n=21; 61.7%) and reported weight-centered anxiety (n=23; 67.6%). Twenty patients (58.8%) were treated with topiramate, 17 of whom had adequate symptomatic responses. CONCLUSION Our SRED patients showed female preponderance, amnesia during the episodes, association with other sleep disorders, use of hypnotics, weight-centered anxiety, and positive response to topiramate. The presence of anxiety focused on weight in most patients may be an important element in the emergence of this behavior during sleep.

Abstract
The intimate relationship between sleep and epilepsy has long been recognized, yet our understanding of the relationship is incomplete. In this article we address four key issues in this area. First, we consider the reciprocal interaction between sleep and epilepsy. Sleep state clearly influences seizure onset, particularly in certain epilepsy syndromes. The converse is also true; epilepsy may disrupt sleep, either directly through seizures and epileptiform activity, or indirectly through medication-related effects. Unraveling the influences of sleep stage, epilepsy syndrome, and drug effects is challenging, and the current state of knowledge is reviewed. Secondly, accurate diagnosis of sleep-related epilepsy can be difficult, particularly the distinction of nocturnal frontal lobe epilepsy (NFLE) from arousal parasomnias. The challenges in this area, along with work from the authors, are discussed. Thirdly, we will explore the putative relationship between obstructive sleep apnea (OSA) and epilepsy, including the effect of OSA on quality of life; this will lead us to a brief exploration of the effects of OSA on neuroendocrine function. Finally, we will review the evidence surrounding the role of sleep in sudden unexpected death in epilepsy (SUDEP).

Abstract
Sleep-related eating disorder (SRED) is characterised by eating episodes during the first period of the night sleep with partial loss consciousness, and amnesia. It can rarely be induced by some drugs, including zolpidem. We present a video report of a patient with a 1-year history of SRED caused by zolpidem causing important repercussions in the sleep structure and life quality. The night eating episodes ceased promptly with discontinuation of zolpidem. Upon the follow-up, the sleep structure improved and the daily consequences disappeared. As in few reported cases of zolpidem-induced SRED, our patient was suffering from the parasomnia for a long time before the diagnosis. Active exclusion of symptoms suggestive of SRED in patients under zolpidem treatment can avoid the deleterious effect of the sleep disorder.

Abstract
Introduction Somnambulism or sleepwalking is a disorder of arousal from non-rapid eye movement sleep. The prevalence of sleep-related eating disorder has been found to be approximately between 1% and 5% among adults. Many cases of medication-related somnambulism and sleep-related eating disorder-like behavior have been reported in the literature. Quetiapine, an atypical antipsychotic medication, has been associated with somnambulism but has not yet been reported to be associated with sleep-related eating disorder. Case presentation Case 1 is a 51-year-old obese African American male veteran with a body mass index of 34.11kg/m2 and severe sleep apnea who has taken 150mg of quetiapine at bedtime for more than one year for depression. He developed sleepwalking three to four nights per week which resolved after stopping quetiapine while being compliant with bi-level positive pressure ventilation therapy. At one year follow-up, his body mass index was 32.57kg/m2. Case 2 is a 50-year-old African American female veteran with a body mass index of 30.5kg/m2 and mild sleep apnea who has taken 200mg of quetiapine daily for more than one year for depression. She was witnessed to sleepwalk three nights per week which resolved after discontinuing quetiapine while being treated with continuous positive airway pressure. At three months follow-up, her body mass index was 29.1kg/m2. Conclusion These cases illustrate that quetiapine may precipitate complex motor behavior including sleep-related eating disorder and somnambulism in susceptible patients. Atypical antipsychotics are commonly used in psychiatric and primary care practice, which means the population at risk of developing parasomnia may often go unrecognized. It is important to recognize this potential adverse effect of quetiapine and, to prevent injury and worsening obesity, discuss this with the patients who are prescribed these medications.

Abstract
Parasomnias are abnormal behaviors emanating from or associated with sleep. Sleepwalking and related disorders result from an incomplete dissociation of wakefulness from nonrapid eye movement (NREM) sleep. Conditions that provoke repeated cortical arousals, or promote sleep inertia lead to NREM parasomnias by impairing normal arousal mechanisms. Changes in the cyclic alternating pattern, a biomarker of arousal instability in NREM sleep, are noted in sleepwalking disorders. Sleep-related eating disorder (SRED) is characterized by a disruption of the nocturnal fast with episodes of feeding after an arousal from sleep. SRED is often associated with the use of sedative-hypnotic medications; in particular, the widely prescribed benzodiazepine receptor agonists. Recently, compelling evidence suggests that nocturnal eating may in some cases be a nonmotor manifestation of Restless Legs Syndrome (RLS). rapid eye movement (REM) Sleep Behavior Disorder (RBD) is characterized by a loss of REM paralysis leading to potentially injurious dream enactment. The loss of atonia in RBD often predates the development of Parkinson's disease and other disorders of synuclein pathology. Parasomnia behaviors are related to an activation (in NREM parasomnias) or a disinhibition (in RBD) of central pattern generators (CPGs). Initial management should focus on decreasing the potential for sleep-related injury followed by treating comorbid sleep disorders. Clonazepam and melatonin appear to be effective therapies in RBD, whereas paroxetine has been reported effective in some cases of sleep terrors. At this point, pharmacotherapy for other parasomnias is less certain, and further investigations are necessary.

Abstract
BACKGROUND/OBJECTIVE Sleep-related eating disorder (SRED) may have some common clinical features with sleepwalking and with eating behavior disorders. The objective of this study was to compare clinical, sleep, and eating behavior measures in patients with SRED vs. sleepwalkers and controls. METHODS Overall, 15 patients with SRED, 21 sleepwalkers, and 20 age- and sex-matched healthy volunteers underwent interviews, completed sleep, anxiety, depression, and eating behavior scales, and had a night-time videopolysomnography. RESULTS Patients with SRED were mainly women, had disease onset in adulthood, suffered nightly episodes and insomnia, and had more frequent eating problems in childhood and higher current anorexia scores than sleepwalkers and controls. Unlike controls, they shared several commonalities with sleepwalkers, including a high frequency (66%) of past or current sleepwalking, a similar timing of parasomnia episodes during the first half of the night, numerous arousals from stage N3, and a similarly altered level of daytime sleepiness and anxiety, but higher awareness during parasomnia episodes. Conversely, only 10% of sleepwalkers ate during their sleepwalking episodes. On videopolysomnography, the eating episodes occurred mostly within 1min after awakening from stage N2 (n=9) or stage N3 (n=6). The frequencies of restless legs syndrome, periodic leg movements, and sleep apnea were similar across the three groups. CONCLUSIONS Patients with SRED share several clinical commonalities with sleepwalkers (although their level of awareness is higher) plus former or current eating behavior problems. It suggests that they have specialized a former sleepwalking behavior toward sleep-related eating because they are more vulnerable to eating behavior problems during the daytime.

Abstract
The increasing prevalence of obesity has lead to an increase in the prevalence of sleep disordered breathing in the general population. The disproportionate structural characteristics of the pharyngeal airway and the diminished neural regulation of the pharyngeal dilating muscles during sleep predispose the obese patients to pharyngeal airway collapsibility. A subgroup of obese apneic patients is unable to compensate for the added load of obesity on the respiratory system, with resultant daytime hypercapnia. Weight loss using dietary modification and life style changes is the safest approach to reducing the severity of sleep apnea, but its efficacy is limited on the long run. Although it has inherent risks, bariatric surgery provides the most immediate result in alleviating sleep apnea. Obesity has been linked also to narcolepsy. The loss of neuropeptides co-localized in hypocretin neurons is suggested as the potential mechanism. Poor sleep quality, which leads to overall sleep loss and excessive daytime sleepiness has also become a frequent complaint in this population. Identifying abnormal nocturnal eating is critically important for patient care. Both sleep related eating disorder and night eating syndrome are treatable and represent potentially reversible forms of obesity.

Abstract
Sleep-related eating disorder (SRED) is characterized by recurrent episodes of involuntary eating during sleep period and is often associated with restless legs syndrome (RLS). Although pharmacotherapy is recommended for SRED patients, no drug have shown promising effects so far. The patient, a 48-year-old Japanese housewife, first visited our clinic and complained about nighttime eating. She had a history of hypertension, diabetes mellitus, sleep apnea syndrome, and depression. Insomnia appeared 10 years before the first visit and she often received hypnosedatives; at the same time, she developed nocturnal eating episodes. She had amnesia for these episodes, and she felt urge to move her legs while sleeping. The patient was diagnosed with SRED and RLS. Reduction in the doses of triazolam decreased her nighttime eating frequency, and her complete amnesia changed to vague recall of eating during night. Clonazepam 1.0 mg at bedtime decreased nocturnal eating frequency from 1 to 2 times per month, though sleepwalking remained. Administration of pramipexole 0.125 mg relieved all symptoms including SRED, RLS, and sleepwalking. This is the first paper to report that the combination of clonazepam and pramipexole therapy-reduced SRED episodes and RLS symptoms.

Abstract
Clinical applications of electroencephalography (EEG) are used with different objectives, EEG being a noninvasive and painless procedure. In respect of eating disorders, in the 1950s a new line of study about the neurological bases of anorexia nervosa was started and has since been developed. The purpose of this review is to update the existing literature data on the main findings in respect of EEG in eating disorders by means of a search conducted in PubMed. Despite the fact that weight gain tends to normalize some brain dysfunctions assessed by means of EEG, the specific effect of gaining weight remains controversial. Different studies have reported that cortical dysfunctions can be found in patients with anorexia nervosa even after weight gain, whereas others have reported a normalization of EEG in respect of the initial reduced alpha/ increased beta power in those patients with refeeding. Findings of studies that have analyzed the possible relationship between eating disorders and depression, based on sleep EEG disturbances, do not support the idea of eating disorders as a variant of depression or affective disorders. Some EEG findings are very consistent with previous neuroimaging results on patients with anorexia nervosa, reporting neural disturbances in response to stimuli that are relevant to the pathology (eg, stimuli like food exposure, different emotional situations, or body images).
