Childhood narcolepsy and autism spectrum disorders: four case reports
We report four children with narcolepsy type 1 (NT1) and autism spectrum disorder (ASD) - Asperger syndrome (AS). To the best of our knowledge co-occurrence of NT1 and AS has not been described in the literature. (Source: Sleep Medicine)

Automatic detection of cataplexy
Although being the most specific symptom of narcolepsy type 1 (NT1), cataplexy is currently investigated by clinical interview only, with potential diagnostic pitfalls. Our study aimed at testing the accuracy of an automatic video detection of cataplexy in NT1 patients vs. non-cataplectic subjects undergoing a standardized test with emotional stimulation.

Sleep duration and remaining teeth among older people
We examined the associations between the number of teeth and sleep duration in older people, considering the evidence linking fewer teeth and sleep apnoea through changes in jaw position. (Source: Sleep Medicine)

Corrigendum to “Media consumption and sleep quality in early childhood: results from the Ulm SPATZ Health Study” [Sleep Medicine 45 (2018) 7–10]
The authors regret that there has been a mislabeling of the variable on book reading. The previously labelled categories “never”, “up to 1h”, and “> 1h/d ” denoted in the methods section should have been labelled “up to 1h”, “1–2h/d”, and “> 2h/d ”, respectively. The same change in labelling of book reading applies to Figure 1 and Table S1 in the online supplement as well as footnote 3 to Table 2. For the electronic media indicators, groups remain as indicated in the methods section and throughout the manuscript. (Source: Sleep Medicine)

Sleep spindles are altered in early- but not late-onset nightmare recallers
Nightmares are a common sleep disorder, defined as highly disturbing mentation which usually awakens the individual from rapid eye movement (REM) sleep. While nightmares are mainly a REM sleep phenomenon, Picard-Deland et al. (in press) recently showed an association between nightmare recall and sleep spindles, which are a non-rapid eye movement (NREM) oscillatory feature; results pointed to fewer slow spindles and a higher oscillatory frequency for fast spindles among frequent nightmare recallers compared with controls.

Michel Jouvet as a Clinical Neurophysiologist and Neurologist
While the world reputation of Michel Jouvet in sleep research is based on his huge work on sleep and paradoxical sleep, especially in cats, a far less-known part of his activity was dedicated to investigate and take care of patients with neurological diseases. Indeed, he was also a physician, specialized in neurophysiology and working at the neurological hospital of Lyon. He was most interested first in patients with disorders of consciousness and secondly in those with sleep/wake disorders, and especially in modafinil for the treatment of patients with narcolepsy and idiopathic hypersomnia.

Predialysis fluid overload linked with quality of sleep in patients undergoing hemodialysis
Hemodialysis (HD) patients are exposed to dysregulated fluid balance which can lead to overhydration. Poor sleep quality and excessive daytime sleepiness are particularly common in these patients, however the relationship between fluid status and sleep quality and daytime sleepiness has not yet been studied. Therefore, the aim of this study is to evaluate the correlations between fluid status and sleep quality and daytime sleepiness in HD patients. (Source: Sleep Medicine)

Memories of Michel
Preface: By far the most frequent approach to writing an editorial for a special issue of a journal is for the Guest Editor to simply summarize the high points of each of the articles in the issue. However, I believe this is an easy way out; and that it is a disservice that does nothing positive for the authors, the readers, or the journal. If an editor chooses this route, why would the person holding the special issue in his or her hand read the entirety of each of the articles? If the reader does not do this, there will be no access to, and no recall of, the full contribution of each of the articles. (Source: Sleep Medicine)

A Preliminary Study on Potential association between psychopathological status and rhythmic masticatory muscle activity of young patients with sleep bruxism in Tianjin China
The aim of this cross-sectional study was to assess the psychological status of patients with bruxism and to explore the potential relationship between psychological status and rhythmic masticatory muscle activity (RMMA), since the basic manifestation of sleep bruxism is RMMA.

Co-occurrence of respiratory event-related and spontaneous rhythmic movements in REM sleep
Rhythmic movement disorder (RMD) consists of repetitive, stereotyped movements typically occurring at sleep-wake transition and after arousals in sleep, and is usually seen during infancy and childhood, generally resolving by adolescence and rarely persisting into adulthood [1-3]. It occurs most commonly in non-rapid eye movement (NREM) sleep, but may sometimes occur in rapid eye movement (REM) sleep (see further on). It has been described in association with obstructive sleep apnea (OSA) in adults [4, 5], often responding to continuous positive airway pressure treatment [6, 7]. (Source: Sleep Medicine)

Factors influencing adherence to continuous positive airway pressure treatment in obstructive sleep apnea and mortality associated with treatment failure – a national registry-based cohort study
Adherence to continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) is crucial. Our aim was to identify protective and risk factors against the discontinuation of CPAP treatment in patients with OSA and to estimate the mortality risk in those who were non-adherent to CPAP therapy.

Sub-regions of the dorsal raph é nucleus receive different inputs from the brainstem
The dorsal raphe nucleus (DRN) through its extensive efferent projections has been implicated in a great variety of physiological and behavioral functions including the regulation of the sleep-wake cycle. This nucleus is composed of five sub-regions defined according to the distribution of its serotonergic (5-HT) neurons. In addition to its heterogeneity in neuronal populations, the DRN contains a great diversity of 5-HT neuronal subtypes identified based on their electrophysiological characteristics, morphology and sub-regional distribution.
