Non–Rapid Eye Movement Sleep Parasomnias
Neurologic Clinics, 2005Parasomnias are unpleasant or undesirable behavioral or experiential phenomena that occur during sleep. Once believed unitary phenomena related to psychiatric disorders, it is now clear that parasomnias result from several different phenomena and usually are not related to psychiatric conditions. Parasomnias are categorized as primary (disorders of the

Biochemical regulation of non-rapid-eye-movement sleep
Frontiers in Bioscience, 2003The concept, that sleep regulatory substances (sleep factors) exist, stems from classical endocrinology and is supported by positive transfer experiments in which tissue fluids obtained from sleepy or sleeping animals elicited sleep when injected into recipient animals.

Non–Rapid Eye Movement Sleep and Overlap Parasomnias
Continuum, 2017This article reviews the spectrum of non-rapid eye movement (non-REM) sleep parasomnias, including sleepwalking, confusional arousals, and sleep terrors, which represent the range of phenotypic disorders of arousal from non-REM sleep that occurs in children and adults.The International Classification of Sleep Disorders, Third Edition (ICSD-3 ...

Parasomnias Occurring in Non–Rapid Eye Movement Sleep
Continuum, 2020This article discusses the clinical manifestations, diagnosis and differential diagnosis, pathophysiology, and management of parasomnias occurring in non-rapid eye movement (REM) sleep.Disorders of arousal are characterized by dissociated sleep, with wake and sleep phenomena intermingling, and local sleep, in which different areas of the brain exist ...

Crocin promotes non‐rapid eye movement sleep in mice
Molecular Nutrition & Food Research, 2012Crocus sativusL. (saffron) has been traditionally used for the treatment of insomnia and other diseases of the nervous systems. Two carotenoid pigments, crocin and crocetin, are the major components responsible for the various pharmacological activities ofC. sativusL.

Rapid eye movement sleep, non-rapid eye movement sleep, dreams, and hallucinations
Current Psychiatry Reports, 2005After the discovery of rapid eye movement (REM) sleep in 1953, oneiric activity was long thought to be associated uniquely with REM sleep. Subsequent evaluation of sleep in humans combining neurophysiologic, psychophysiologic, and, more recently, functional neuroimaging investigations, has instead shown that dreaming also occurs during non-REM (NREM ...

Journal of Stroke and Cerebrovascular Diseases, 2021
Sleep-disordered breathing adversely impacts stroke outcomes. We investigated whether sleep-disordered breathing during rapid eye movement sleep and non-rapid eye movement sleep differentially influenced stroke outcomes.Acute ischemic stroke patients who finished polysomnography within 14 days of stroke onset from April 2010 to August 2018 were ...

Understanding non rapid eye movement sleep through neuroimaging
The World Journal of Biological Psychiatry, 2010Non rapid eye movement (nonREM) sleep has long been considered as a state of brain quiescence, partly because brain oxygen metabolism, cerebral blood flow and glucose metabolism were shown to be decreased during nonREM sleep compared with wakefulness and REM sleep. However, emission techniques used for these measurements are characterized by relatively

Electroencephalogram analysis of non-rapid eye movement sleep in rats
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1988Sleep states and power spectra of the electroencephalogram were determined for consecutive 4-s epochs during 24 h in rats that had been implanted with electrodes under deep pentobarbital anesthesia. The power spectra in non-rapid eye movement sleep (NREMS) showed marked trends: low-frequency activity (0.75-7.0 Hz) declined progressively throughout the
