Abstract
Normal circadian rhythms are synchronized to a regular 24 h environmental light–dark cycle, and the suprachiasmatic nucleus and the hormone melatonin have important roles in this process. Desynchronization of circadian rhythms, as occurs in chronobiological disorders, can produce severe disturbances in sleep patterns. According to the International Classification of Sleep Disorders, circadian rhythm sleep disorders (CRSDs) include delayed sleep phase syndrome, advanced sleep phase syndrome, non-24 h sleep–wake disorder, jet lag and shift-work sleep disorder. Disturbances in the circadian phase position of plasma melatonin levels have been documented in all of these disorders. There is compelling evidence to implicate endogenous melatonin as an important mediator in CRSD pathophysiology, although further research involving large numbers of patients will be required to clarify whether the disruption of melatonin secretion is a causal factor in CRSDs. In this Review, we focus on the use of exogenous melatonin and light therapy to treat the disturbed sleep–wake rhythms seen in CRSDs.
Key Points
-
Circadian rhythm desynchronization is common among patients who present with sleep disorders
-
Circadian rhythm sleep disorders (CRSDs) include delayed sleep phase syndrome, advanced sleep phase syndrome, non-24 h sleep–wake rhythm disorder, shift-work sleep disorder and jet lag
-
The hormone melatonin is thought to have an important role in the synchronization of sleep–wake rhythm and rest–activity cycles with the light–dark cycle
-
Exogenous melatonin, sometimes in combination with light therapy, can be beneficial in resynchronizing sleep patterns in patients with CRSDs
-
Well-conducted, large clinical trials are warranted to further assess the efficacy and safety of chronotherapy as a treatment for CRSDs
