Panagiotis Bargiotas, Iris Arnet, Michael Frei, Christian R Baumann, Kaspar Schindler, Claudio L Bassetti
BACKGROUND: Sleepwalking (SW) is found to affect children predominantly, but it can persist or appear de novo even among adults. In this study, we assessed the demographic, clinical and polysomnographic profile, trigger factors and associated comorbidities of adult-onset (AO-SW) and childhood-onset (CO-SW) adult sleepwalkers. METHODS: In adult sleepwalkers, a structured clinical interview, a battery of questionnaires, video-polysomnography (v-PSG) and standard electroencephalography (EEG) were performed...

Parasomnia is a common pediatric sleep disorder that can cause parents or caregivers distress when experienced by their children. Based on the International Classification of Sleep Disorders, parasomnias can be divided into two subgroups: non-rapid eye movement (NREM) parasomnias and rapid eye movement (REM) parasomnias. REM sleep parasomnias include nightmares, REM behavior disorder, and sleep paralysis, whereas NREM sleep parasomnias include disorders of arousal such as confusional arousals, sleepwalking, sleep talking, night terrors, and sleep-related eating disorder...

PURPOSE OF REVIEW: Sleep-wake disorders occur in 10% to 28% of children and differ somewhat in pathophysiology and management from sleep-wake disorders in adults. This article discusses the diagnosis and management of key childhood sleep disorders. RECENT FINDINGS: The role of sleep in memory consolidation and in the facilitation of learning has been increasingly recognized, even at the toddler stage. Cataplexy, a key feature of narcolepsy type 1, may be subtle in childhood and characterized by transient muscle weakness isolated to the face...

The term "sleep experiences," coined by Watson (2001), denotes an array of unusual nocturnal consciousness phenomena; for example, nightmares, vivid or recurrent dreams, hypnagogic hallucinations, dreams of falling or flying, confusional arousals, and lucid dreams. Excluding the latter, these experiences reflect a single factor of atypical oneiric cognitions ("general sleep experiences"). The current study is an opinionated mini-review on the associations of this factor-measured with the Iowa sleep experiences survey (ISES, Watson, 2001)-with psychopathological symptoms and stress...

Sleep-related abnormal sexual behaviors (sexsomnia) are classified as a subtype of NREM sleep parasomnias. Sexsomnia has been reported as part of parasomnia overlap disorder (POD) in two other patients. We present the case of a 42-year-old male patient with video-polysomnography (vPSG) documented POD. The patient had sleepwalking, sleep-related eating, confusional arousals, sexsomnia, sleeptalking, and REM sleep behavior disorder (RBD). Confusional arousals and RBD were documented during the vPSG. This case had the added complexity of obstructive sleep apnea (OSA) playing a role in sleepwalking and sleep related eating, with good response to nasal continuous positive airway pressure (nCPAP)...

STUDY OBJECTIVES: Despite the high prevalence and clinical relevance of NREM parasomnias, data on supportive genetic markers are scarce, and mainly refer to sleepwalking only. METHODS: We retrospectively analyzed clinical, polysomnographic, and HLA findings of 74 adults (37 men) with NREM parasomnia gathered from four neurological sleep centers. Parasomniac events were classified according to ICSD-2 criteria. HLA DQB1 genotyping was compared to regional-matched reference allele-frequencies...

Sleepwalking (SW) is a parasomnia, an abnormal behavior occurring during sleep. SW is a non-REM sleep parasomnia, an arousal disorder, like sleep terrors and confusional arousals. SW results from an incomplete arousal from slow-wave sleep, some regions of the cerebral cortex being awake and allowing movement and vision for example and others being asleep, preventing memorization or judgment. Usually, SW is a quiet wandering of a child that occurs rarely (several times a month or a year), requiring no medical advice and treatment...

BACKGROUND: The pattern of recreational drug use has changed over the last decade and now includes a multitude of substances sold as "research chemicals" or new psychoactive substances, "NPS". In France, synthetic cathinones emerged in 2008 (while first mentioned by the French police force in 2007 first alerts among users appeared in 2008) and have grown to be popular drugs of abuse. Under the Official Journal dated 11th June 2010, only mephedrone has been listed as narcotics but "designer drugs" have synthesized new substitute cathinones in order to avoid anti-drug laws...

Parasomnias represent a category of disorders that involve complex behaviors or emotional experiences, arising from or occurring during sleep, which might be also associated with (incomplete) awakening. These phenomena are classified as REM- or Non-REM-parasomnias. In particular the latter, including confusional arousal, sleepwalking and sleep terrors but also REM-sleep behavior disorder might result in criminal consequences. Using polysomnography, the pathophysiological mechanisms of these disorders have been investigated thoroughly...

The aim of this study was to investigate whether different shift work schedules were associated with nonrapid eye movement (NREM)- and/or REM-related parasomnias. A total of 2198 nurses with different work schedules participated in a longitudinal cohort study. The parasomnia questions were included in the fourth wave of the data collection, with a response rate of 74.1%. Logistic regression analyses with the different parasomnias as dependent variables were conducted. Nurses working two shift (day and evening) and nurses working three shift (day, evening and night) rotational schedules had increased risk of confusional arousal, a NREM-related parasomnia, compared to nurses working daytime only (odds ratios = 2...

Spinocerebellar ataxias (SCA) are autosomal dominant neurodegenerative disorders that affect the cerebellum and its connections, and have a marked clinical and genetic variability. Machado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3)--MJD/SCA3--is the most common SCA worldwide. MJD/SCA3 is characterized classically by progressive ataxia and variable other motor and non-motor symptoms. Sleep disorders are common, and include rapid eye movement (REM) sleep behaviour disorder (RBD), restless legs syndrome (RLS), insomnia, excessive daytime sleepiness, excessive fragmentary myoclonus and sleep apnea...

OBJECTIVE: To characterize parasomnia behaviors on arousal from NREM sleep in Parkinson's Disease (PD) and Multiple System Atrophy (MSA). METHODS: From 30 patients with PD, Dementia with Lewy Bodies/Dementia associated with PD, or MSA undergoing nocturnal video-polysomnography for presumed dream enactment behavior, we were able to select 2 PD and 2 MSA patients featuring NREM Parasomnia Behviors (NPBs). We identified episodes during which the subjects seemed to enact dreams or presumed dream-like mentation (NPB arousals) versus episodes with physiological movements (no-NPB arousals)...

Narcolepsy in children is a serious disorder marked by a chronic course and lifelong handicap in school performance and choice of employment, by free time activity limitation, and by behavior and personality changes, all of which constitute a major influence on the quality of life. Increased daytime sleepiness may be the only sign at the disease onset, with attacks of sleep becoming longer and lasting up to hours. Also present may be confusional arousals with features of sleep drunkenness. Paradoxically, preschool and young children may show inattentiveness, emotional lability, and hyperactive behavior...

Up to 50% of children will experience a sleep problem. Early identification of sleep problems may prevent negative consequences, such as daytime sleepiness, irritability, behavioral problems, learning difficulties, motor vehicle crashes in teenagers, and poor academic performance. Obstructive sleep apnea occurs in 1% to 5% of children. Polysomnography is needed to diagnose the condition because it may not be detected through history and physical examination alone. Adenotonsillectomy is the primary treatment for most children with obstructive sleep apnea...

Delirium is a disturbance of consciousness and cognition that results in a confusional state. It tends to fluctuate in intensity and is often observed in older patients. Sleep is a window of vulnerability for the occurrence of delirium and sleep disorders can play a role in its appearance. In particular, delirious episodes have been associated with obstructive sleep apnoea syndrome, which is reported to be frequent in the elderly. Hereby, we present a case-report documenting the sudden onset of a confusional state triggered by obstructive sleep apnoea-induced arousal, together with a review of the literature on the topic...

Non-rapid eye movement (NREM) arousal sleep disorders (confusional arousal, somnambulism and sleep terror) are self-limiting and temporary phenomena which cannot be attributed to medical or psychiatric factors. However, very occasionally they can be the cause of unintentional injury to self or others. We describe the case of an 18-year-old who engaged in self-injurious behaviour while asleep. This behaviour could be attributed to confusional arousal.

The prevalence of sleep related complaints is reported by questionnaire studies to be as high as 83.3% in children with autism spectrum disorders (ASD). Questionnaire studies report the presence of various parasomnia in ASD. However, no polysomnographic study reports non-REM parasomnias and only a single study reports REM related parasomnias in ASD. We investigated the prevalence and characteristics of sleep disorders by polysomnographic study and questionnaires in a cohort of 23 children with ASD and 23 age-matched children of a non-autistic comparison group...
