INTRODUCTION: Video-EEG has been used to characterize genetic generalized epilepsies (GGE). For best performance, sleep recording, photic stimulation, hyperventilation, and neuropsychological protocols are added to the monitoring. However, risks and benefits of these video-EEG protocols are not well established. The aim of this study was to analyze the efficacy and safety of a video-EEG neuropsychological protocol (VNPP) tailored for GGE and compare its value with that of routine EEG (R-EEG)...

Study Objectives: Idiopathic rapid eye movement sleep behavior disorder (iRBD) is considered as a prodromal stage of synucleinopathy. Although loss of functional connectivity is implicated in neurodegenerative diseases, network characteristics of electroencephalography (EEG) in iRBD are unknown. Therefore, we evaluated resting-state EEG functional connectivity to identify the brain network changes in patients with iRBD. Methods: We prospectively enrolled 20 patients with polysomnography-confirmed iRBD and 16 control subjects...

Health care providers have significant opportunities to identify individuals at near-term risk for suicide, but lack empirical data on near-term risk factors. This study aimed to identify dynamic, state-related risk factors observed by clinical practitioners within the last 30 days of life of 157 patients who died by suicide and to compare these near-term risk factors among patients who denied versus responded positively to having suicide ideation (SI) when last asked by a clinical practitioner prior to their death...

RATIONALE: Gamma-hydroxybutyrate (GHB) is a putative neurotransmitter, a drug of abuse, an anesthetic agent, and a treatment for neuropsychiatric disorders. In previous electroencephalography (EEG) studies, GHB was shown to induce an electrophysiological pattern of "paradoxical EEG-behavioral dissociation" characterized by increased delta and theta oscillations usually associated with sleep during awake states. However, no detailed source localization of these alterations and no connectivity analyses have been performed yet...

Rapid eye movement sleep (REMS) plays important role in maintenance of normal brain functions. Neurons containing various neurotransmitters in different brain regions interact to regulate this complex phenomenon in health and diseases. The number of neuronal projections, their firing rates and neurotransmitter levels vary in different brain regions under various conditions leading to normal or altered patho-physio-behavioral states. In this study using high performance liquid chromatography (HPLC) we quantified noradrenaline (NA) and gamma-amino butyric acid (GABA) levels in locus coeruleus (LC), dorsal raphe (DR), pedunculo-pontine tegmentum (PPT), frontal lobe (FL), cortex and hippocampus (Hippo) in control and after 96h REMS deprivation (REMSD) rats...

Takayuki Yamashita, Akihiro Yamanaka
The lateral hypothalamic area (LHA) of the diencephalon is crucially involved in controlling instinctive behavior such as sleep-wake cycle and feeding behavior. LHA is a heterogeneous structure that contains spatially intermingled, genetically distinct cell populations. Among LHA neurons, orexin/hypocretin (OX) neuron is the key cell type that promotes waking, and specific loss of OX neurons results in narcolepsy. Melanin-concentrating hormone (MCH) containing neurons are known to be active during rapid eye movement (REM) sleep and stimulation of these neurons promotes REM sleep...

Sleep Awareness Week, the National Sleep Foundation's annual campaign to educate the public about the importance of sleep in health and safety, will be observed April 23-29, 2017. The amount of sleep a person needs changes with age. Adults need ≥7 hours each night to promote optimal health and well-being (1); children and adolescents require even more sleep. Sleep needs decrease from 12-16 hours of sleep per 24 hours (including naps) for infants aged 4-12 months to 8-10 hours of sleep for teenagers aged 13-18 years (2)...

Among the most co-occurring conditions in autism spectrum disorders (ASD), there are sleep disorders which may exacerbate associated behavioral disorders and lead to intensification of existing autistic symptoms. Several studies investigating the use of melatonin in the treatment of sleep disorders in ASD have shown comparative efficiency in sleep with little or no side effects. Here we report a case of ASD with non-24-hour rhythm and the effect of melatonin in circadian parameters by actigraphy. Visual analysis of the first 10 days recorded and the periodogram suggest that this patient showed a non-24-hour rhythm...

The circadian system coordinates internal events in a daily schedule to make sure that the body systems are synchronized to environmental time and internal cues. One important behavioral aspect of the circadian system is the chronotype. It is usually assessed through subjective questionnaires, being the Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ) one of the most used. It classifies individuals into three major categories: morning, evening, and intermediate types. Recently, it has been hypothesized the existence of a fourth chronotype, the bimodal type, through an algorithm derived from the MEQ responses...

OBJECTIVE: Emerging research demonstrates race differences in diurnal cortisol slope, an indicator of hypothalamic-pituitary-adrenocortical (HPA)-axis functioning associated with morbidity and mortality, with African Americans showing flatter diurnal slopes than their White counterparts. Sleep characteristics are associated with both race and with HPA-axis functioning. The present report examines whether sleep duration may account for race differences in cortisol dynamics. METHOD: Participants were 424 employed African American and White adults (mean age = 42...

New age technologies are ubiquitous in the lives of adolescents. Recent trends in media use suggest that adolescents are spending more time than ever engaging with technologies, and are able to do so in virtually all settings at any time. Given that new age technologies are so heavily integrated within the daily life of adolescents, the health risks and benefits they offer must be closely examined. In this systematic review, we present recent literature related to the implications of new age technologies on adolescent health...

BACKGROUND: Sleep is a critical aspect of people's well-being and as such assessing sleep is an important indicator of a person's health. Traditional methods of sleep assessment are either time- and resource-intensive or suffer from self-reporting biases. Recently, researchers have started to use mobile phones to passively assess sleep in individuals' daily lives. However, this work remains in its early stages, having only examined relatively small and homogeneous populations in carefully controlled contexts...
