Abstract:
:Because there is insufficient cellular energy for organisms to perform their functions at the same constant rate and at the same time, all biologic processes show rhythmicity, each with its own unique frequency, amplitude, and phase. Optimal sleep and wakefulness requires proper timing and alignment of desired sleep-wake schedules and circadian rhythm-related periods of alertness. Persistent or recurrent mismatch between endogenous circadian rhythms and the conventional sleep-wake schedules of the environmental day can give rise to several circadian rhythm sleep disorders. Evaluation of suspected circadian rhythm sleep disorders requires proper monitoring of sleep diaries, often over several days to weeks. This article discusses the disorders of the circadian sleep-wake cycle and the therapeutic measures to correct the same.
