Sleep is normally a time of motor quiescence. Motor disorders may, however, arise during the different phases of sleep. Nocturnal myoclonus or periodic leg movements in sleep usually occur during light sleep and may be considered the motor accompaniment of the cyclic fluctuations in excitability typical of such stages.

Sleep disorders are, in part, attributable to genetic variability across individuals. There has been considerable progress in understanding the role of genes for some sleep disorders, such as the identification of a human leukocyte antigen gene for narcolepsy. For other sleep disorders, such as insomnia, little work has been done.

Recently some hypotheses explaining sleep disturbances in depression have been proposed. One hypothesis assumes an advanced phase position of the circadian pacemaker controlling a.o. REM sleep (REMS) production. In another a deficiency of process S is proposed.

Sleep disorders in imprinting disorders
S.S. Korsakov Journal of Neurology and PsychiatryA literature review of the current state of the etiology and pathogenesis of genomic imprinting disorders such as Angelman syndrome and Prader—Willi syndrome was performed. The mechanisms of the development of sleep disorders associated with these syndromes related to impaired expression of specific genes are considered in detail.

Neuroimaging of sleep and sleep disorders
Current Neurology and Neuroscience Reports, 2006Herein are presented the results of research in the area of sleep neuroimaging over the past year. Significant work has been performed to clarify the basic mechanisms of sleep in humans. New studies also extend prior observations regarding altered brain activation in response to sleep deprivation by adding information regarding vulnerability to sleep ...

lthough descriptions of sleep-disordered breathing (SDB) have been ound in medical and nonmedical literature for centuries, most of our urrent knowledge about this condition has been obtained in the past 30 ears. SDB—snoring, limited respiratory flow leading to arousals or xihemoglobin desaturations (hypopneas), or complete cessation of irflow (apneas)—

The Nurse Practitioner, 1985
An inability to sleep or sleep prematurely ended or interrupted by periods of wakefulness (insomnia) are some of the most frequent complaints heard from patients. Insomnia can be situationally related or persistent in nature. Persistent insomnia may be associated with biological rhythm disturbances, drug dependency, psychophysiologic abnormalities ...

SLEEP AND NEUROMUSCULAR DISORDERS
Neurologic Clinics, 1996Polysomnographic evaluation in the sleep laboratory is recommended for patients with neuromuscular disorders who develop symptoms and sign of sleep-wake abnormality or nocturnal respiratory failure. Nocturnal sleep-related ventilatory alterations may occur in disproportion to the severity of the neuromuscular disorder. Diaphragmatic paralysis occurring

Nearly all drugs of abuse and alcohol have considerable effects on sleep efficiency, sleep continuity, sleep stages, and consequent next-day alertness. It has been hypothesized that such drug effects on sleep and wake function may act as contributing factors in maintaining compulsive and excessive drug use, as well as factors that increase the risk for
