RESUMO
Somnambulism, also called sleepwalking, classified as a non-rapid eye movement sleep parasomnia, encompasses a range of abnormal paroxysmal behaviors, leading to sleepwalking in dissociated sleep in an altered state of consciousness with impaired judgment and configuring a kind of hierarchical continuum with confusional arousal and night terror. Despite being generally regarded as a benign condition, its potential severity entails social, personal, and even forensic consequences. This comprehensive review provides an overview on the current state of knowledge, elucidating the phenomenon of somnambulism and encompassing its clinical manifestations and diagnostic approaches.

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.

STUDY OBJECTIVES: We created a Dutch version of the Paris Arousal Disorders Severity Scale (PADSS), which assesses non-rapid eye movement (NREM) parasomnia symptoms over the past year (PADSS-year). This questionnaire was previously validated in patients with sleep walking and/or sleep terrors (SW/ST). We validated the questionnaire in SW/ST patients, and in a broader population, including patients with confusional arousals, comorbidities, and medication users ("other NREM parasomnias"). Furthermore, we introduced a version covering the past month (PADSS-month), with the potential purpose of evaluating symptom evolution and treatment response. METHODS: We compared PADSS scores among 54 SW/ST patients, 34 age-matched controls, and 23 patients with other NREM parasomnias. We evaluated discriminative capacity, internal consistency, and construct validity. Furthermore, we assessed the test-retest reliability and treatment response of PADSS-month. RESULTS: Healthy controls scored significantly lower than both patient groups. We found an excellent diagnostic accuracy (area under the curve PADSS-year 0.990, PADSS-month 0.987) and an acceptable internal consistency. Exploratory factor analysis identified 3 components: "behaviors outside the bed," "behaviors in/around the bed," and "violent behaviors," with the former 2 factors reflecting the distinction between SW and ST. PADSS-month showed an acceptable test-retest reliability (0.75). Additionally, PADSS-month significantly decreased after pharmaceutical and/or behavioral treatment. This change was correlated with the clinical impression of the caregiver, implying that PADSS-month is sensitive to treatment effects. CONCLUSIONS: The Dutch PADSS questionnaire can be used as a screening tool in a broad population of patients with NREM parasomnia, not only SW/ST. Furthermore, we validated a PADSS-month version to assess the evolution of symptoms and treatment effect. CITATION: van Mierlo P, Hermans L, Arnulf I, Pijpers A, Overeem S, van Gilst M.

Sleep terrors (STs) are sleep disorders characterized by abrupt arousal from sleep with autonomic hyperactivity and inappropriate behavior. Though a common condition in childhood that usually affects children between 4 and 12 years of age, STs, however, may be present even in adulthood. The exact etiology of STs is not known yet, however, several hypotheses have been proposed over the years, identifying some potential genetic, neurodevelopmental, or other causes. Nevertheless, a useful pathophysiological model identified a common cascade of predisposing, priming, and precipitating factors, which could help to explain and sometimes prevent STs. Establishing a correct diagnosis is mandatory for appropriate management, as several conditions (such as other parasomnias or nocturnal seizures) may mimic STs. Furthermore, we also described some conditions which can be comorbid to STs, like some medical or psychological disorders. A number of treatment options have been proposed, ranging from only sleep hygiene practices to pharmacological therapies; we reviewed some of the most prominent ones. In spite of the fact that STs have long been considered benign disorders, which tend to reduce spontaneously over the years, they may have unexpected consequences on the child but also on the caregivers.

BACKGROUND: Arousal Disorders (DoA) include Confusional Arousals, Sleepwalking and Sleep Terrors. DoA diagnosis is mainly clinical but no validated questionnaires exist for DoA screening according to the criteria of the International Classification of Sleep Disorders, Third Edition. Recently our group proposed the Arousal Disorders Questionnaire (ADQ) as a new diagnostic tool for DoA diagnosis. The objective of this study was to evaluate the diagnostic accuracy of the ADQ in a sleep and epilepsy center. METHODS: One interviewer blinded to clinical and video-polysomnographic (VPSG) data administered the ADQ to 150 patients consecutively admitted to our Sleep and Epilepsy Centers for a follow-up visit. The final diagnosis, according to VPSG recordings of at least one major episode, classified patients either with DoA (DoA group) or with other sleep-related motor behaviors confounding for DoA (nDoA group). RESULTS: 47 patients (31%) composed the DoA group; 56 patients with REM sleep behavior disorder, 39 with sleep-hypermotor epilepsy, six with night eating syndrome, and two with drug-induced DoA composed the nDoA group. The ADQ had a sensitivity of 72% (95% CI: 60-82) and a specificity of 96% (95% CI: 89-98) for DoA diagnosis; excluding the items regarding consciousness and episode recall, sensitivity was 83% (95% CI: 71-90) and specificity 93% (95% CI: 86-97). CONCLUSIONS: The ADQ showed good accuracy in screening patients with DoA in a sleep and epilepsy center setting. Diagnostic criteria related to cognition and episode recall reduced ADQ sensitivity, therefore a better definition of these criteria is required, especially in adults.

BACKGROUND: Sleep terrors are common, frightening, but fortunately benign events. Familiarity with this condition is important so that an accurate diagnosis can be made. OBJECTIVE: To familiarize physicians with the clinical manifestations, diagnosis, and management of children with sleep terrors. METHODS: A PubMed search was completed in Clinical Queries using the key terms "sleep terrors" OR "night terrors". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article. RESULTS: It is estimated that sleep terrors occur in 1 to 6.5% of children 1 to 12 years of age. Sleep terrors typically occur in children between 4 and 12 years of age, with a peak between 5 and 7 years of age. The exact etiology is not known. Developmental, environmental, organic, psychological, and genetic factors have been identified as a potential cause of sleep terrors. Sleep terrors tend to occur within the first three hours of the major sleep episode, during arousal from stage three or four non-rapid eye movement (NREM) sleep. In a typical attack, the child awakens abruptly from sleep, sits upright in bed or jumps out of bed, screams in terror and intense fear, is panicky, and has a frightened expression. The child is confused and incoherent: verbalization is generally present but disorganized. Autonomic hyperactivity is manifested by tachycardia, tachypnea, diaphoresis, flushed face, dilated pupils, agitation, tremulousness, and increased muscle tone. The child is difficult to arouse and console and may express feelings of anxiety or doom. In the majority of cases, the patient does not awaken fully and settles back to quiet and deep sleep. There is retrograde amnesia for the attack the following morning. Attempts to interrupt a sleep terror episode should be avoided. As sleep deprivation can predispose to sleep terrors, it is important that the child has good sleep hygiene and an appropriate sleeping environment. Medical intervention is usually not necessary, but clonazepam may be considered on a short-term basis at bedtime if sleep terrors are frequent and severe or are associated with functional impairment, such as fatigue, daytime sleepiness, and distress. Anticipatory awakening, performed approximately half an hour before the child is most likely to experience a sleep terror episode, is often effective for the treatment of frequently occurring sleep terrors. CONCLUSION: Most children outgrow the disorder by late adolescence. In the majority of cases, there is no specific treatment other than reassurance and parental education. Underlying conditions, however, should be treated if possible and precipitating factors should be avoided.

This article reports on seven cases of night terror disorder in children with no previous history of parasomnias, or night time disturbance. All children were admitted to a metropolitan children's hospital with a traumatic fracture of the femur and treated with Thomas' traction splint, a phenomenon not previously reported in the literature. The characteristic presentation of a night terror is described and a strategy for immediate nursing management of a night terror is suggested. Various forms of projective play therapy as a safe short-term treatment are described to assist children with night terror disorder.

OBJECTIVES: To investigate the prevalence of REM sleep behavior disorder (RBD) in patients with inflammatory arthritis (IA) to ascertain if RBD could be an internal red flag signaling a fluctuating state of inflammation based on the theory of "protoconsciousness". MATERIALS & METHODS: One hundred and three patients with a confirmed diagnosis of IA were consecutively recruited. The patients underwent general (IA activity, functional status, laboratory tests) and neurological evaluations. A neurologist investigated RBD and REM sleep parasomnias in a semi-structured interview. Sleep quality was assessed with the Pittsburgh Sleep Quality Index, while the risk of obstructive sleep apnea syndrome (OSAS) was evaluated with the Berlin questionnaire. Beck Depression Inventory II and State-Trait Anxiety Inventory investigated depression and anxiety. RESULTS: Patients had a mean age of 53.7 ± 14.6 years, 65% were women; 57.3% were in a clinically active phase of IA. Two women fulfilled ICSD-3 criteria for RBD appearing 11 years after and 20 years before IA onset respectively. 31 patients scored positive for nightmare disorder (ND), 8 for recurrent isolated sleep paralysis. 65 (63.1%) patients reported poor sleep quality and 25 (24.3%) resulted at high risk for OSAS. 32 (31.0%) patients scored positively for depression or anxiety. CONCLUSIONS: The prevalence of RBD in patients with IA did not differ from that in the general population, whereas ND presented a 2-fold increased prevalence. Whether RBD can be considered a red flag signaling an internal danger remains an open question, while ND may be a new player in this intriguing relation.

OBJECTIVE: To assess video-polysomnographic (vPSG) criteria and their cutoff values for the diagnosis of disorders of arousal (DOAs; sleepwalking, sleep terror). METHODS: One hundred sixty adult patients with DOAs and 50 sex- and age-matched healthy participants underwent a clinical evaluation and vPSG assessment to quantify slow wave sleep (SWS) interruptions (SWS fragmentation index, slow/mixed and fast arousal ratios, and indexes per hour) and the associated behaviors. First, a case-control analysis was performed in 100 patients and the 50 controls to define the optimal cutoff values using receiver operating characteristic curves. Their sensitivity was then assessed in the other 60 patients with DOAs. RESULTS: The SWS fragmentation index and the mixed, slow, and slow/mixed arousal indexes and ratios were higher in patients with DOAs than controls. The highest area under the curve (AUC) values were obtained for the SWS fragmentation and slow/mixed arousal indexes (AUC = 0.88 and 0.90, respectively). The SWS fragmentation index cutoff value of 6.8/h reached a sensitivity of 79% and a specificity of 82%. The slow/mixed arousal index had a sensitivity of 94% for the 2.5/h cutoff, and 100% specificity for 6/h. Both parameters showed good interrater agreement, and their sensitivities were confirmed in the second group of patients. Combining electroencephalographic parameters and video-based behavioral analyses increased the correct classification rate up to 91.3%. INTERPRETATION: Frequent slow/mixed arousals in SWS and complex behaviors during vPSG are strongly associated with DOAs, and could be promising biomarkers for the diagnosis of non-rapid eye movement parasomnias.

Introduction: To describe patients with sexsomnia and to contrast their clinical and sleep measures with those of healthy controls and sleepwalkers. Aims and Methods: Subjects referred for sexsomnia and for sleepwalking/night terror were interviewed, completed the Paris Arousal Disorder Severity Scale (PADSS), and were monitored 1-2 nights with video-polysomnography. Results: Seventeen patients (70.6% male, aged 17-76 years) had sexsomnia, with amnestic fondling of the bed partner (n = 11), complete sexual intercourse (n = 8), masturbation (n = 8), and spontaneous orgasm (n = 1). The sexual behaviors were more direct during sleep than during wakefulness (n = 12), leading to 6 sexual assaults, including intra-conjugal rape (n = 3), assault of a family member (n = 2), rape of a friend (n = 1), and forensic consequences (n = 2). In 47% of sexsomnia patients, there was a history or current occurrences of sleepwalking/night terrors. Patients with sexsomnia had more N3 awakenings than healthy matched controls and the same amount as regular sleepwalkers. Half of them presented evidence of cortico-cortical dissociation, including concomitant slow (mostly frontal) and rapid (mostly temporal and occipital) electroencephalography (EEG) rhythms, with concomitant N3 penile erection in 1 case. Of 89 sleepwalkers, 10% had previous episodes of amnestic sexual behaviors, with a higher PADSS-A score and a trend of a higher total PADSS score than the 80 sleepwalkers without sexsomnia. Conclusion: In this single-center series, we confirmed the male predominance of sexsomnias and its potential for severe clinical and forensic consequences. The results suggest a continuum of regular sleepwalking, sleepwalking with occasional sexsomnia, and quasi-exclusive sexsomnia.

STUDY OBJECTIVES: To examine scalp and source power topography in sleep arousals disorders (SADs) using high-density EEG (hdEEG). METHODS: Fifteen adult subjects with sleep arousal disorders (SADs) and 15 age- and gender-matched good sleeping healthy controls were recorded in a sleep laboratory setting using a 256 channel EEG system. RESULTS: Scalp EEG analysis of all night NREM sleep revealed a localized decrease in slow wave activity (SWA) power (1-4 Hz) over centro-parietal regions relative to the rest of the brain in SADs compared to good sleeping healthy controls. Source modelling analysis of 5-minute segments taken from N3 during the first half of the night revealed that the local decrease in SWA power was prominent at the level of the cingulate, motor, and sensori-motor associative cortices. Similar patterns were also evident during REM sleep and wake. These differences in local sleep were present in the absence of any detectable clinical or electrophysiological sign of arousal. CONCLUSIONS: Overall, results suggest the presence of local sleep differences in the brain of SADs patients during nights without clinical episodes. The persistence of similar topographical changes in local EEG power during REM sleep and wakefulness points to trait-like functional changes that cross the boundaries of NREM sleep. The regions identified by source imaging are consistent with the current neurophysiological understanding of SADs as a disorder caused by local arousals in motor and cingulate cortices. Persistent localized changes in neuronal excitability may predispose affected subjects to clinical episodes.

OBJECTIVE: To objectively measure daytime sleepiness and to assess for clinical and polysomnographic determinants of mean sleep latency in adult patients with somnambulism (sleepwalking [SW]) or sleep terrors (ST) compared with controls. METHODS: Thirty drug-free adult patients with primary SW or ST, and age-, sex-, and body mass index-matched healthy controls underwent a standardized clinical interview, completed questionnaires including the Epworth Sleepiness Scale, and underwent one night of video polysomnography followed by the Multiple Sleep Latency Test (MSLT). RESULTS: Excessive daytime sleepiness defined as Epworth Sleepiness Scale score >10 was reported in 66.7% of patients and 6.7% of controls. The temporal pattern of sleep latencies in individual MSLT trials differed between patients and controls, with progressive increased sleep latency in patients across the trials in contrast to a "U curve" for controls. We did not find between-group differences regarding the mean sleep latency on the 5 MSLT trials, but did observe reduced sleep latencies in patients for the first 2 trials. Despite increased slow-wave sleep disruptions found in patients (i.e, more micro-arousals and hypersynchronous high-voltage delta waves arousals), we did not find polysomnographic characteristic differences when comparing sleepy patients for either subjective or objective daytime sleepiness on the MSLT compared with alert patients. CONCLUSION: Excessive daytime sleepiness is a common complaint in subjects with SW or ST and shorter sleep latencies in the early morning hours. Despite an increased slow-wave sleep fragmentation found in these patients, we did not identify any association with the level of daytime sleepiness.

Interest in the treatment of nightmares has greatly increased over the last several years as research has demonstrated the clinical significance of nightmare disorder. This paper provides an overview of nightmare disorder, its clinical relevance, and the leading treatments that are available. In particular, the paper defines nightmare disorder and then summarize the recent literature examining the clinical relevance of nightmare disorder, including its relation to post-traumatic stress disorder and other psychiatric conditions. The relation between nightmares and suicidality is also discussed. Recent findings on the treatment of nightmare with imagery rehearsal therapy and prazosin are then summarized. Lastly, the paper comments on potential future uses of nightmare treatment including using imagery rehearsal therapy or prazosin as a first-line intervention for post-traumatic stress disorder and using these treatments as an adjunctive therapy to reduce suicide risk in those at risk of suicide with nightmares.

BACKGROUND: Arousal disorders may have serious health consequences. OBJECTIVE: To develop a scale assessing the severity of arousal disorders (Paris Arousal Disorders Severity Scale, PADSS). SETTING: University hospital. DESIGN: Controlled study. PARTICIPANTS: Consecutive patients (older than 15 y), with sleepwalking (SW) and/or sleep terrors (ST), subjects with previous SW/ST, normal controls and patients with rapid eye movement sleep behavior disorder. INTERVENTION: The self-rated scale listed 17 parasomniac behaviors (PADSS-A), assessed their frequency from never to twice or more per night (PADSS-B) and evaluated the consequences (PADSS-C: disturbed sleep, injuries, fatigue, and psychological consequences). The clinimetric properties and face validity of the scale were tested. RESULTS: Half of the 73 patients with SW/ST (more men than women) had injured themselves or others, whereas 15% had concomitant sexsomnia and 23% had amnestic eating behaviors. The total PADSS score (range: 0-50) was 19.4 ± 6.3 (range: 8-36) in this group, 11.7 ± 5.9 in 26 subjects with previous SW/ST, 8.8 ± 3.2 in 26 patients with RBD, and 2.0 ± 3.5 in 53 normal controls (P < 0.05). The PADSS demonstrated high sensitivity (83.6%), specificity (87.8%), internal consistency, and test-retest reliability (0.79). The best cutoff for the total score was at 13/14. Exploratory factor analysis revealed two components: wandering and violence/handling. The complexity of behaviors emerging from N3 sleep (scored on videopolysomnography) positively correlated with scores for the PADSS-total, PADSS-A, PADSS-C, and the "violence/handling" factor. CONCLUSION: This scale had reasonable psychometric properties and could be used for screening and stratifying patients and for evaluating the effects of treatments.

OBJECTIVE: Many patients with panic disorder (PD) experience nocturnal panic attacks. We investigated the differences in demographic variables and symptom characteristics as well as response to treatment among patients with primary day panic (DP), primary nocturnal panic (NP), and the coexistence of DP and NP (DP/NP), and discuss whether NP is a distinct disease category. METHOD: One hundred one consecutive untreated patients with PD were enrolled and subsequently divided into the NP, DP, and DP/NP groups. The presence of 13 panic attack symptom items as well as scores on the Panic Disorder Severity Scale (PDSS) and the Pittsburgh Sleep Quality Index (PSQI) were compared among the groups. After 3 months of regular treatment, PDSS scores were assessed again to evaluate treatment response. RESULTS: Nocturnal panic attacks of the participants were mostly reported to occur in the first tertile of nocturnal sleep. The number of males, onset age, and presence of choking sensation were significantly higher, and the PDSS score was significantly lower in the NP group compared with the other groups. The DP/NP group showed the highest PDSS score, and participants in this group were prescribed the highest doses of medication among all groups. Only diagnostic sub-category was significantly associated with treatment response. The total score for PDSS and PSQI correlated significantly only in the NP group. CONCLUSIONS: DP/NP could be a severe form of PD, while primary NP could be a relatively mild subcategory that may partially share common pathophysiology with adult type night terror.

We report the case of a 43-year-old woman presenting with nocturnal episodes of pain and screaming during sleep starting at age 30. There was no childhood or family history of parasomnia. The events had gradually become more frequent over the years, occurring in the first half of the night within 2 h of sleep onset. There were no triggers, and she had partial amnesia for the events. A diagnosis of adult-onset sleep terrors was made on clinical grounds and supported polysomnographically. Seizures and periodic limb movements were excluded as triggering factors. There was some mild sleep disordered breathing (predominantly non-desaturating hypopnea with a propensity for REM sleep of debatable significance). Imaging of the brain and spine and neurophysiological investigations ruled out lesions, entrapments, or neuropathies as possible causes of pain. Treatment (clonazepam, paroxetine, or gabapentin) was poorly tolerated and made no difference to the nocturnal episodes, while trazodone worsened them. This is the first report of hypnopompic psychic pain in association with a NREM parasomnia. We hypothesize that the pain may represent a sensory hallucination analogous to the more commonly recognized visual NREM parasomnia-associated hypnopompic visual hallucinations and that, as such, it may arise during arousal of the sensory neocortex as confabulatory response.
