Research advances in the study of sleep disorders, circadian rhythm disturbances and Alzheimer’s disease [PDF]

open access: yesFrontiers in Aging Neuroscience, 2022
Although there are still no satisfactory answers to the question of why we need to sleep, a better understanding of its function will help to improve societal attitudes toward sleep. Sleep disorders are very common in neurodegenerative diseases and are a

Circadian Rhythm Sleep Disorders [PDF]

open access: yesNeurologic Clinics, 2012
There have been remarkable advances in our understanding of the molecular, cellular, and physiologic mechanisms underlying the regulation of circadian rhythms, and of the impact of circadian dysfunction on health and disease. This information has transformed our understanding of the effect of circadian rhythm sleep disorders (CRSD) on health ...

Non-24-hour sleep-wake disorder revisited – A case study [PDF]

open access: yesFrontiers in Neurology, 2016
The human sleep-wake cycle is governed by two major factors: a homeostatic hourglass process (process S), which rises linearly during the day, and a circadian process C, which determines the timing of sleep in an approximately 24h rhythm in accordance to

Circadian rhythm and aggressive behavior in community-dwelling schizophrenia patients testing a moderated mediation model [PDF]

open access: yesFrontiers in Psychiatry
BackgroundAggressive behavior in patients with schizophrenia poses significant challenges to community management. Although disruption of circadian rhythm is a recognized risk factor, the underlying mechanisms related to sleep disorders and social ...

Therapeutics for Circadian Rhythm Sleep Disorders [PDF]

open access: yesSleep Medicine Clinics, 2010
The sleep-wake cycle is regulated by the interaction of endogenous circadian and homeostatic processes. The circadian system provides timing information for most physiological rhythms, including the sleep and wake cycle. In addition, the central circadian clock located in the suprachiasmatic nucleus of the hypothalamus has been shown to promote ...

Relationship between circadian rhythm characteristics and chronotypes with multiple sclerosis: literature review

open access: yesNeurologijos seminarai, 2021
Circadian rhythm disorder is described as discrepancy between person’s sleep habits and usual, generally accepted sleep model during 24-hour period. Circadian rhythm disorders affect not only person’s working capacity during the day but also may reduce ...

The role of microRNAs in the molecular link between circadian rhythm and autism spectrum disorder

open access: yesAnimal Cells and Systems, 2023
Circadian rhythm regulates physiological cycles of awareness and sleepiness. Melatonin production is primarily regulated by circadian regulation of gene expression and is involved in sleep homeostasis. If the circadian rhythm is abnormal, sleep disorders,

Circadian rhythm sleep disorders

open access: yesDisease-a-Month, 2011
Circadian rhythm sleep disorders are characterized by a misalignment between the timing of sleep–wake and the external environment that results in insomnia, excessive daytime sleepiness, and impaired waking function. This chapter covers sleep disorders thought to be result of alterations in the endogenous circadian clock, such as delayed sleep phase ...
