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 comprehensive management of chronic disorders such as hypersomnias of childhood requires combining life-style changes with rational pharmacotherapy that is based on treating the symptoms that are most bothersome, the age, comorbidities, and metabolic and endocrine status of the patient. The excessive sleepiness of narcolepsy and idiopathic hypersomnia is best treated with dextroamphetamine or methylphenidate preparations or modafinil/armodafinil. Cataplexy treatment requires sodium oxybate, tricyclic agents, selective norepinephrine reuptake inhibitors or selective serotonin reuptake inhibitors...

Narcolepsy is a chronic sleep disorder characterized by a pentad of excessive daytime sleepiness (EDS), cataplexy, sleep paralysis, hypnagogic/hypnopompic hallucinations, and disturbed nocturnal sleep. While non-pharmacological treatments are sometimes helpful, more than 90% of narcoleptic patients require a pharmacological treatment. Areas covered: The present review is based on an extensive Internet and PubMed search from 1994 to 2017. It is focused on drugs currently in development for the treatment of narcolepsy...

AIMS AND OBJECTIVES: Based on class-I studies, sodium oxybate is regarded as a first-line treatment for both EDS and cataplexy. The cost-effectiveness of sodium oxybate is largely unknown, though. In this study, we estimate the cost-effectiveness of sodium oxybate as treatment for patients with narcolepsy as compared to standard treatment, by calculating incremental cost-effectiveness ratios (cost per quality-adjusted life year, QALY) for patients in a Swedish setting. MATERIALS AND METHODS: Calculations were performed using a Markov model with a 10-year time horizon...

BACKGROUND: Giggle incontinence is a sudden and involuntary episode of urinary incontinence that is provoked by an episode of laughter. Decades of case studies and small research studies have formed the basis of what is known about giggle incontinence; however, much remains unknown about this type of incontinence, leaving the recommendations for clinical management somewhat unguided. METHODS: A systematic review of 22 articles on the topic of "giggle incontinence" and related terms was conducted, including all published articles and commentaries since the term was first seen in print in 1959...

OBJECTIVE: To determine GHB levels in breast milk of women taking sodium oxybate (Xyrem) for treatment of narcolepsy and cataplexy. METHODS: Two women with narcolepsy and cataplexy treated with sodium oxybate before pregnancy collected breast milk for analysis of GHB concentration after resuming sodium oxybate postpartum. One woman collected samples across two consecutive nights (doses: 3.0 gm and 4.5 gm twice per night) five months after delivering her first child; the other collected samples on three separate days (doses: 2...

Narcolepsy type 1 is a life-long, severe, multifaceted disease often arising in childhood or adolescence. Beyond the classical symptoms (excessive daytime sleepiness, cataplexy, hallucinations, sleep paralysis and nocturnal fragmented sleep), metabolic, endocrinological, psychiatric and psychosocial aspects must be considered. Despite the increased awareness after H1N1 pandemic influenza and vaccination, narcolepsy is still misdiagnosed and unrecognized. The peculiar presentation of symptoms in narcoleptic children could in part explain the misdiagnoses...

REVIEW
Christoph Boss, Catherine Roch
The orexin system consists of two G-protein-coupled receptors, orexin 1 and orexin 2 and two endogenous ligands, orexin A and orexin B . It is evolutionarily highly conserved. It is involved in the promotion of wakefulness as well as in anxiety and addictive disorders. In addition, its activation via the Ox1 receptor triggers apoptosis in several cancer cell lines. Dual orexin receptor antagonists are successfully used to treat primary insomnia. The major open questions are now related to the clinical validation of Ox1 selective antagonists...

Hcrt gene inactivation in mice leads to behavioral state instability, abnormal transitions to paradoxical sleep, and cataplexy, hallmarks of narcolepsy. Sleep homeostasis is, however, considered unimpaired in patients and narcoleptic mice. We find that whereas Hcrt(ko/ko) mice respond to 6-h sleep deprivation (SD) with a slow-wave sleep (SWS) EEG δ (1.0 to 4.0 Hz) power rebound like WT littermates, spontaneous waking fails to induce a δ power reflecting prior waking duration. This correlates with impaired θ (6...

AIMS: To estimate the effect of the compound sodium oxybate (SO) on chin muscle tone in sleep, a re-analysis of the results of the international multicenter study SXB-15 was performed, applying a validated semi-automatic analysis of muscle tone. This analysis distinguishes short (<0.5 s) and long (>0.5 s) muscle activity indices per hour (SMI, LMI) in 116 patients with narcolepsy-cataplexy. While stable stimulant medication was permitted, tricyclics and SSRIs were withdrawn. Polysomnographies were performed at baseline (V5), four weeks after titration of SO to 4...

Orexins (orexin-A and orexin-B) are neuropeptides that are reduced in narcolepsy, a sleep disorder that is characterized by excessive daytime sleepiness, sudden sleep attacks and cataplexy. However, it remains unclear how orexins in the brain and orexin neurons are reduced in narcolepsy. Orexin-A has two closely located intramolecular disulfide bonds and is prone to misfolding due to the formation of incorrect disulfide bonds. Protein disulfide isomerase (PDI) possesses disulfide interchange activity. PDI can modify misfolded orexin-A to its native form by rearrangement of two disulfide bonds...

REVIEW
Michihiro Mieda
Orexin A and orexin B are hypothalamic neuropeptides initially identified as endogenous ligands for two orphan G-protein coupled receptors (GPCRs). A deficiency of orexin signaling results in the sleep disorder narcolepsy-cataplexy in humans, dogs, and rodents, a sleep disorder characterized by excessive daytime sleepiness and cataplexy. Multiple approaches, including molecular genetic, electrophysiological, pharmacological, and neuroanatomical studies have suggested that orexins play critical roles in the maintenance of wakefulness by regulating the function of monoaminergic and cholinergic neurons that are implicated in the regulation of wakefulness...
