NREM and REM sleep parasomnias: clinical cases and literature review

Neurologijos seminarai, 2021
Parasomnias are a group of sleep disorders that manifest as abnormal behaviour or movements while falling asleep, during sleep, or before awakening. According to the International Classification of Sleep Disorders (ICSD-3), parasomnias are subdivided ...

The Natural History of Insomnia: Acute Insomnia and First-onset Depression [PDF]

, 2013
Study Objectives: While many studies have examined the association between insomnia and depression, no studies have evaluated these associations 1) within a narrow time frame, 2) with specific reference to acute & chronic insomnia, and 3) using ...

Epilepsy syndromes classification

Epilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.

Rest‐activity patterns across development in two mouse models of autism and epilepsy

Epilepsia Open, EarlyView.
Abstract Objective Sleep disturbances are common in individuals with autism spectrum disorder (ASD) and epilepsy and are increasingly recognized as comorbidities that affect disease severity and quality of life. This study investigated rest‐activity patterns across development in two genetic mouse models relevant to ASD and epilepsy: synapsin 2 (Syn2 ...

Sleep Health in Bulimia Nervosa: A Systematic Review

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Research on sleep in bulimia nervosa (BN) is methodologically varied and yields inconsistent findings. This review synthesised BN‐sleep studies and examined whether comorbid mood disorders contribute to sleep disturbance. Method PsycINFO, Medline (Ovid), and Scopus were searched for English or French quantitative studies comparing ...

A moderate increase of physiological CO2 in a critical range during stable NREM sleep episode: A potential gateway to REM sleep

Frontiers in Neurology, 2012
Sleep is characterized as rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. Studies suggest that wake-related neurons in the basal forebrain, posterior hypothalamus and brainstem and NREM sleep-related neurons in the anterior-hypothalamic

Reversed and increased functional connectivity in non-REM sleep suggests an altered rather than reduced state of consciousness relative to wake

Scientific Reports, 2021
Sleep resting state network (RSN) functional connectivity (FC) is poorly understood, particularly for rapid eye movement (REM), and in non-sleep deprived subjects.

Monitoring and assessment for obstructive sleep apnea

FlexMat, EarlyView.
This review systematically classifies Obstructive Sleep Apnea (OSA) monitoring indicators into three categories: physical, biochemical, and electrophysiological indicators, and lists several methods for each category. Abstract Obstructive sleep apnea (OSA) is a common chronic sleep‐disordered breathing disease characterized by recurrent upper airway ...

Entrained cortical delta–spindle activity, not periodic synchrony, prevents arousal by NREM thalamic bursts

Communications Biology
Thalamic neurons discharge tonically during wakefulness and rapid-eye-movement (REM) sleep, but switch to burst firing during non-REM (NREM) sleep. It has been hypothesized that NREM thalamic bursts do not serve as a cortical “wake-up” signal due to ...

Decoupling of sleep-dependent cortical and hippocampal interactions in a neurodevelopmental model of schizophrenia [PDF]

, 2012
Rhythmic neural network activity patterns are defining features of sleep, but interdependencies between limbic and cortical oscillations at different frequencies and their functional roles have not been fully resolved.
