Single-channel EEG classification of sleep stages based on REM microstructure.

Healthc Technol Lett 2021 Jun 20;8(3):58-65. Epub 2021 Apr 20.

Department of Neuroscience "Rita Levi Montalcini" Università degli Studi di Torino Torino Italy.

Rapid-eye movement (REM) sleep, or paradoxical sleep, accounts for 20-25% of total night-time sleep in healthy adults and may be related, in pathological cases, to parasomnias. A large percentage of Parkinson's disease patients suffer from sleep disorders, including REM sleep behaviour disorder and hypokinesia; monitoring their sleep cycle and related activities would help to improve their quality of life. There is a need to accurately classify REM and the other stages of sleep in order to properly identify and monitor parasomnias. Read More

Sleep and Epilepsy, Clinical Spectrum and Updated Review.

Sleep Med Clin 2021 Jun;16(2):389-408

UCLA Seizure Disorder Center, Brain Research Institute, David Geffen School of Medicine at UCLA, 10833 Le Conte Avenue, Los Angeles, CA 90095, USA.

Electroencephalogram (EEG) recording is essential in the evaluation of complex movement and behaviors during sleep, but in particular for differentiating epileptic versus nonepileptic events. In general, epileptiform discharges occur with greater density in the first few nonerapid eye movement cycles, and approximately 12% to 20% of seizures occur exclusively at night. This review examines the epilepsy types and syndromes whose presentation is strongly influenced by the sleep state, with an appraisal about the role that sleep plays in facilitating seizures, while deleaneatign EEG findings and clinical manifestation.

The Clinical Evaluation of Sleep-Related Movement Disorders.

Sleep Med Clin 2021 Jun 18;16(2):223-231. Epub 2021 Apr 18.

Sleep Unit, Sleep Research Institute, Calle Padre Damián 44 Madrid 28036, Spain. Electronic address:

This article is a comprehensive review of the clinical evaluation of sleep-related movement disorders. In this review, the authors present a practical approach to help clinicians identify the "pattern recognition" of movement and behavior disorders during sleep, with the process of translating a particular movement that occurs when asleep, with clinically classifying disorders, and with obtaining an etiologic diagnosis. The aim is not to provide an exhaustive review of the literature, but to concentrate on the most important symptoms, so the clinical approach can be improved and the best choices can be made during the diagnostic process.

Perioperative Management of Insomnia, Restless Legs, Narcolepsy, and Parasomnias.

Anesth Analg 2021 05;132(5):1287-1295

Division of Pulmonary, Critical Care and Sleep Medicine, MetroHealth Medical Center, Case Western Reserve University, Cleveland, Ohio.

Obstructive sleep apnea (OSA) has been shown to increase risk of adverse perioperative events. More recently, investigators have begun to examine other common sleep disorders to assess how they may be impacted by the perioperative environment, as well as influence postoperative outcomes. There are a number of mechanisms by which such common sleep disorders (eg, insomnia, restless legs syndrome, narcolepsy, and parasomnias) may have consequences in the perioperative setting, both related to the underlying pathophysiology of the diseases as well as their treatments.

Association of Sleepwalking and REM Sleep Behavior Disorder With Parkinson Disease in Men.

JAMA Netw Open 2021 Apr 1;4(4):e215713. Epub 2021 Apr 1.

Department of Nutritional Sciences, The Pennsylvania State University, University Park.

Importance: Previous studies conducted among patients with Parkinson disease (PD) reported that parasomnias other than rapid eye movement (REM) sleep behavior disorder (RBD), particularly sleepwalking (SW), are associated with PD severity. However, it remains unclear whether the presence of SW is associated with altered odds of having PD in a population-based study.

Objective: To evaluate whether probable SW, either alone or co-occurring with probable RBD, is associated with higher odds of PD in men. Read More

Center for Advanced Research in Sleep Medicine, CIUSSS-NÎM - Hôpital du Sacré-Coeur de Montréal, Montreal, QC, Canada.

Nightmares are highly dysphoric dreams that are well-remembered upon awakening. Frequent nightmares have been associated with psychopathology and emotional dysregulation, yet their neural mechanisms remain largely unknown. Our neurocognitive model posits that nightmares reflect dysfunction in a limbic-prefrontal circuit comprising medial prefrontal and anterior cingulate cortices, hippocampus, and amygdala. Read More

Bruxism in Children and Adolescents with Down Syndrome: A Comprehensive Review.

Medicina (Kaunas) 2021 Mar 1;57(3). Epub 2021 Mar 1.

Department of Clinical Specialistic and Dental Sciences, Marche Polytechnic University, 60126 Ancona, Italy.

The role of bruxism in children and adolescents with Down syndrome, the most often diagnosed congenital syndrome, is still unclear. Therefore, this study aims to conduct a narrative review of the literature about bruxism in children and adolescents with Down syndrome to identify the prevalence, risk factors, and possible treatments of this disorder. Although an accurate estimate of its prevalence could not be inferred, it appears that bruxism is more prevalent in Down syndrome individuals rather than in the general pediatric population.
