Abstract: Circadian rhythm sleep-wake disorders (CRSWDs ) is a group of sleep-wake disorders caused by circadian rhythm disorder. Patients complain of difficulty in falling asleep, early waking, daytime drowsiness, which are often misdiagnosed and delayed for treatment. The American Academy of Sleep Medicine (AASM) updated the diagnostic criteria in 2014, and issued relevant treatment guidelines in 2015. In recent years, many countries have issued relevant clinical practice guidelines or consensus. The treatment of circadian rhythm sleep-wake disorder is different from the common sleep-wake disorder, with the focus on non-pharmacologic circadian rhythm regulation to reset the normal 24-hour sleep-wake rhythm. This article mainly introduces its treatment strategy and method.

Key words: circadian rhythm, sleep-wake disorders, light therapy, behavior management
