Some sleep-related disturbances are simply temporary inconveniences while others are potentially more serious. Sleep apnea is the major respiratory disorder of sleep. Other serious sleep-related disorders are narcolepsy and clinical

May 17, 2021 It is defined as sleep-disordered breathing (SDB) that is characterized by prolonged partial upper airway obstruction and/or intermittent complete obstruction (obstructive apnea) that disrupts normal ventilation during sleep and disturbs normal sleep patterns [1,2]. Although obstruction of the upper airway during sleep remains its main

Epilepsy and sleep have a reciprocal relationship. Sleep, sleep deprivation and sleep disorders may affect epilepsy, facilitating seizure occurrence; in turn sei-zures during sleep, drugs and interictal epileptic activ-ity may fragment sleep, worsening seizures in a vicious circle, and interfere with its restorative and neuroplastic functions

Genetics of Delayed Sleep Phase Syndrome

Delayed sleep phase syndrome (DSPS) is a circadian rhythm disorder in which patients have sleep-wake cycles that are abnormally shifted forward. Other types of circadian rhythm disorders are non-24-h sleep-wake syndrome (N-24) and advanced sleep phase syndrome (ASPS). N-24 patients have a sleep cycle that has daily delay

For instance, the twin concordance rate in narcolepsy is 30%, 18 ranges from 54% to 83% in RLS, 19 , 20 and has been reported as variable in insomnia but may be as high as 47%, 21 - 23 indicating both genetic and environmental contributions to the pathogenesis or expression of

It has long been thought that lack of sleep was caused by these disorders, yet there may be evidence to support a bidirectional relation between the two.

Dec 08, 2017 The understanding of migraine pathophysiology is advancing rapidly. Improved characterisation and diagnosis of its clinical features have led to the view of migraine as a complex, variable disorder of nervous system function rather than simply a vascular headache.

Sleep remains a relatively understudied phenomenon, despite being essential in some form to most vertebrate life. Although humans spend about one-third of their lives in the sleep state, an under-standing and recognition of its importance for our well-being are severely lacking.

Stage 3 (N3) is the deep sleep stage, when the beneficial functions of sleep occur: the body repairs and regrows tissues, builds bone and muscle and strengthens the immune system.

adults experience such disorders. As the cost of sleep-related problems is a considerable burden to society, research into sleep disorders is a matter of priority. The sleep-wake cycle is generated through both circadian and homeostatic processes (1, 2) and altered circadian rhythmicity induces circadian rhythm sleep disorders (CRSD).


to sleep. Narcolepsy, therefore, consists of two major abnormalities: an inabil-ity to maintain wakefulness in daytime and intrusion of REM sleep phenomena (hypnagogic hallucinations, paralysis, and perhaps cataplexy) into wakefulness. Rapid transitions to REM sleep recorded during naps in the sleep laboratory are diagnostic for narcolepsy.
