Decision-making After Sleep Restriction

The aim of this project is to investigate whether enhancing sleep intensity locally in the prefrontal cortex (PFC) can counteract a deterioration of cognitive control and therefore the pre...

Effect of Sleep Restriction on Adipose Tissue and Skeletal Muscle Insulin Sensitivity

Inadequate sleep is an independent risk factor for metabolic abnormalities (such as obesity, insulin resistance, and hyperglycemia). Women report sleep disruption during the menopause tran...

The Cognitive and Metabolic Effects of Sleep Restriction in Adolescents

The aim of this study is to examine the neurobehavioural and glucose metabolic responses to two successive cycles of sleep restriction and recovery in adolescents, and to determine the ben...

Effects of Chronic Sleep Restriction in Young and Older People

The purpose of this study is to examine the consequences of chronic sleep restriction on nighttime sleep, daytime alertness, performance and memory functions, and metabolic and cardiovascu...

Sleep Subtypes in Adolescent Depression

The purpose of this study is to compare sleep neurophysiology and behavior in adolescents with MDD with hypersomnia (MDD-HYP) and insomnia (MDD-INS) with healthy controls (HC). In addition...

Which Factors Are the Most Important for Predicting Sleep Quality in Obstructive Sleep Apnea Patients with Obesity?

Both obstructive sleep apnea (OSA) and obesity are associated with poor sleep quality. However, there have been no studies investigating sleep quality in OSA patients with obesity. The aims of this st...

Objective Measures of Sleep Apnea and Actigraphy-based Sleep Characteristics as Correlates of Subjective Sleep Quality in an Epidemiological Study: The Jackson Heart Sleep Study.

Self-reported "sleep quality" often is assessed in epidemiologic studies. However, the bases for variation in sleep quality is not fully understood. We quantified the extent to which subjective sleep ...

A sleep intervention study comparing effects of sleep restriction and fragmentation on sleep and vigilance and the need for recovery.

Sleep deprivation is present not only in sleep disorders but also in numerous high demanding jobs and negatively affects cognition, performance and health. We developed a study design to distinguish t...

The Effect of Auricular Acupressure on Sleep Disturbance Among Patients With Leukemia: A Feasibility Study.

Auricular acupressure (AA) is widely used in East Asia and Europe to manage patients with sleep disturbance. This feasibility study was performed to demonstrate the potential of AA for sleep disturban...

The Impact of Self-Reported Sleep Quantity on Perceived Decision-Making in Sports Officials during a Competitive Season.

: While sleep research in athletes is extensive, no research has investigated sleep in sports officials during a competitive season. This study explored the (a) self-reported quantity and quality of s...

Medical and Biotech [MESH] Definitions

Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.

Habits and practices conducive to getting the right amount and quality of sleep, and include responding to environmental factors that may influence one's sleep.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)

Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of REM sleep, and nonspecific parasomnias. (From Thorpy, Sleep Disorders Medicine, 1994, p191)

A sleep disorder of central nervous system origin characterized by prolonged nocturnal sleep and periods of daytime drowsiness. Affected individuals experience difficulty with awakening in the morning and may have associated sleep drunkenness, automatic behaviors, and memory disturbances. This condition differs from narcolepsy in that daytime sleep periods are longer, there is no association with CATAPLEXY, and the multiple sleep latency onset test does not record sleep-onset rapid eye movement sleep. (From Chokroverty, Sleep Disorders Medicine, 1994, pp319-20; Psychiatry Clin Neurosci 1998 Apr:52(2):125-129)
