Circadian Rhythm Sleep Disorder: Irregular Sleep Wake Rhythm Type.
Irregular Sleep Wake Rhythm Disorder (ISWRD) is characterized by the relative absence of a circadian pattern in an individual's sleep-wake cycle. Significant changes in circadian regulation occur with aging and with neurodegenerative diseases, such as Alzheimer's disease prevalent in older adults, which are likely to contribute to the prevalence of ISWRD seen in these populations, although ISWR...
متن کاملSleep-wake as a biological rhythm.
Evidence that the sleep-wake rhythm is generated endogenously has been provided by studies employing a variety of experimental paradigms such as sleep deprivation, sleep displacement, isolating subjects in environments free of time cues, or imposing on subjects sleep-wake schedules widely deviating from 24 hours. The initial observations obtained in isolated subjects revealed that the period of...
متن کاملAge-associated difference in circadian sleep-wake and rest-activity rhythms.
Using actigraphic monitoring of wrist activity, we investigated the sleep and rest-activity patterns of 65 young, middle-aged, old and the oldest subjects in their natural environmental conditions. To assess the effects of age and gender on sleep and circadian rhythms in activity, multivariate analyses were performed. Age significantly affected circadian sleep and rest-activity rhythms. In the ...
متن کاملEndogenous neuropeptide S tone influences sleep-wake rhythm in rats.
Neuropeptide S (NPS) is an endogenous peptide that exerts wakefulness promoting, analgesic, and anxiolytic effects when administered exogenously. However, it remains to be determined if endogenous NPS tone is involved in the control of the diurnal sleep-wake cycle, or spontanous behavior. In this study, we examined the effects of the NPS receptor antagonist [D-Cys((t)Bu)(5)]NPS (2 and 20 nmol, ...
متن کاملVitamin B12 treatment for sleep-wake rhythm disorders.
Vitamin B12 (VB12) was administered to two patients suffering for many years from different sleep-wake rhythm disorders. One patient was a 15-year-old blind girl suffering from a free-running sleep-wake rhythm (hypernychthemeral syndrome) with a period of about 25 h. In spite of repeated trials to entrain her sleep-wake cycle to the environmental 24-h rhythm, her free-running rhythm persisted f...
