A novel adhesive biosensor system for detecting respiration, cardiac, and limb movement signals during sleep: validation with polysomnography.

Nat Sci Sleep 2018 26;10:397-408. Epub 2018 Nov 26.

Neurology Department, Massachusetts General Hospital, Boston, MA 02114, USA.

Background: Although in-lab polysomnography (PSG) remains the gold standard for objective sleep monitoring, the use of at-home sensor systems has gained popularity in recent years. Two categories of monitoring, autonomic and limb movement physiology, are increasingly recognized as critical for sleep disorder phenotyping, yet at-home options remain limited outside of research protocols. The purpose of this study was to validate the BiostampRC sensor system for respiration, electrocardiography (ECG), and leg electromyography (EMG) against gold standard PSG recordings. Read More

The first night effect in multiple sclerosis patients undergoing home-based polysomnography.

Nat Sci Sleep 2018 26;10:337-344. Epub 2018 Oct 26.

NeuroCure Clinical Research Center, Charité-Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Berlin, Germany.

Background: The first night effect (FNE) is a polysomnography (PSG) habituation effect in the first of several consecutive in-laboratory PSGs (I-PSGs). The FNE is caused by the discomfort provoked by electrodes and cables and the exposure to an unfamiliar environment. A reverse FNE (RFNE) with an improved sleep in the first night is characteristic of insomnia, presumably because the video PSG in the sleep laboratory leads to a decrease in the negatively toned cognitive activity.

Video polysomnographic findings in non-rapid eye movement parasomnia.

J Sleep Res 2018 Oct 8:e12772. Epub 2018 Oct 8.

Sleep Disorders Centre, Guy's Hospital, London, UK.

Although video polysomnography (vPSG) is not routinely recommended for the evaluation of typical cases of non-rapid eye movement (NREM) parasomnias, it can aid diagnosis of unusual cases, other sleep disorders and complicated cases with REM behaviour disorder (RBD), and in differentiating parasomnias from epilepsy. In this study, we aimed to assess vPSG findings in consecutive patients with a clinical diagnosis of NREM-parasomnia covering the whole phenotypic spectrum. Five hundred and twelve patients with a final diagnosis of NREM parasomnia who had undergone vPSG were retrospectively identified. Read More

Comparison of computerized methods for rapid eye movement sleep without atonia detection.

Sleep 2018 Oct;41(10)

Department of Clinical Neurophysiology, Danish Center for Sleep Medicine, Rigshospitalet Glostrup, Denmark.

Rapid eye movement (REM) sleep without atonia detection is a prerequisite for diagnosis of REM sleep behavior disorder (RBD). As the visual gold standard method is time-consuming and subjective, several automated methods have been proposed. This study aims to compare their performances: The REM atonia index (RAI), the supra-threshold-REM-activity metric, the Frandsen index, the short/long muscle activity indices, and the Kempfner index algorithms were applied to 27 healthy control participants (C), 25 patients with Parkinson's disease (PD) without RBD (PD-RBD), 29 patients with PD and RBD (PD + RBD), 29 idiopathic patients with RBD, and 36 patients with periodic limb movement disorder (PLMD).

Sleep-dependent motor sequence memory consolidation in individuals with periodic limb movements.

Sleep Med 2017 Dec 28;40:23-32. Epub 2017 Sep 28.

The Brain & Mind Institute, Western University, London, Ontario, Canada; Department of Psychology, Western University, London, Ontario, Canada; School of Psychology, University of Ottawa, Ottawa, Ontario, Canada; The Royal's Institute for Mental Health Research, Ottawa, Ontario, Canada; University of Ottawa Brain and Mind Research Institute, Ottawa, Ontario, Canada. Electronic address: http://socialsciences.uottawa.ca/sleep-lab/.

Periodic limb movements (PLMs) during sleep increase with age and are associated with striatal neurodegeneration and dopamine deficiency. Limb movements are often associated with disruptions to non-rapid eye movement (NREM) sleep. Motor skill memory consolidation recruits the striatum, and learning-dependent striatal activation is associated with NREM sleep. Read More

Restless Legs Syndrome: clinical features, diagnosis and a practical approach to management.

Pract Neurol 2017 Dec 2;17(6):444-452. Epub 2017 Nov 2.

Department of Neurology, Weill Cornell Medical School, Methodist Neurological Institute, Houston, Texas, USA.

Restless legs syndrome (RLS) is a chronic neurological disorder that interferes with rest and sleep. It has a wide spectrum of symptom severity, and treatment is started when symptoms become bothersome. Dopamine agonists and calcium channel apha-2-delta antagonists (gabapentin, gabapentin enacarbil and pregabalin) are first-line treatments; calcium channel alpha-2-deltas are preferred over dopamine agonists because they give less augmentation, a condition with symptom onset earlier in the day and intensification of RLS symptoms.

Pharmacological Management of Restless Legs Syndrome and Periodic Limb Movement Disorder in Children.

Paediatr Drugs 2018 Feb;20(1):9-17

Sleep Center, Cincinnati Children's Hospital Medical Center, 3333 Burnet Avenue, Cincinnati, OH, 45219, USA.

Restless legs syndrome (RLS) and periodic limb movement disorder (PLMD) are under-recognized sleep disorders in children and adolescents. Several recent epidemiological studies have shown that RLS and PLMD are common in the pediatric population, and if left untreated, may lead to cardiovascular and neurocognitive consequences. Therefore, early diagnosis and intervention may help preventing long-term consequences. Read More

Validation of a non-contact screening device for the combination of sleep-disordered breathing and periodic limb movements in sleep.

Sleep Breath 2018 03 18;22(1):131-138. Epub 2017 Aug 18.

Department of Pneumology, Ruhrlandklinik, West German Lung Center, University Hospital Essen, University-Duisburg Essen, Essen, Germany.

Purpose: Recent studies found that the non-contact screening device SleepMinder (ResMed Sensor Technologies, Dublin, Ireland) detects sleep-disordered breathing (SDB) with high diagnostic accuracy in cohorts suspected of this disorder. However, it was reported that in patients with periodic limb movement in sleep (PLMS), this non-contact device overestimates the apnea-hypopnea index (AHI). We aimed to overcome this limitation by introducing the novel sleep disorder index (SDI) which is sum of the AHI and the period limb movement index (PLMI). Read More

Periodic limb movements of sleep are associated with an increased prevalence of atrial fibrillation in patients with mild sleep-disordered breathing.

Int J Cardiol 2017 Aug 22;241:200-204. Epub 2017 Apr 22.

Division of Pulmonary and Critical Care Medicine, Mayo Clinic, Rochester, MN, USA.

Background: Growing evidence indicates that periodic limb movements of sleep (PLMS) may be related to increased risk of developing cardiovascular disease. However, the association of PLMS with atrial fibrillation (AF) is unclear, especially in patients with sleep-disordered breathing (SDB). This study sought to investigate whether PLMS were associated with increased AF prevalence, independent of established risk factors. Read More

While Isolated Periodic Limb Movement Disorder Significantly Impacts Sleep Depth and Efficiency, Co-Morbid Restless Leg Syndrome Mainly Exacerbates Perceived Sleep Quality.

Eur Neurol 2017 8;77(5-6):272-280. Epub 2017 Apr 8.

Sleep Laboratory and Unit for Chronobiology U78, Brugmann University Hospital, Université Libre de Bruxelles (ULB), Brussels, Belgium.

Background: Restless leg syndrome (RLS) and periodic limb movement (PLM) disorder (PLMD) can affect sleep quality and interfere with daytime functioning. Whether the co-morbidity of RLS further worsens daytime symptoms, sleep architecture and quality in patients with PLMs, is not yet fully clarified.

Methods: Sleep (polysomnography) and daytime symptoms of 47 drug-free patients, assigned to isolated PLMD or co-morbid RLS subgroups, were compared to controls in a retrospective cohort-study (n = 501). Read More
