AI simplified
Abstract
Circadian rhythm sleep disorders may lead to reduced sleep quality due to misalignment with the day-night cycle.
- Delayed sleep phase syndrome and advanced sleep phase syndrome are examples of circadian rhythm sleep disorders.
- Non-24 hour sleep-wake syndrome and irregular sleep-wake pattern disorder are also included in this category.
- Patients with these disorders often struggle to maintain normal social hours.
- Current treatments include both drug options, like hypnotics and melatonin, and nondrug options, such as bright light therapy and chronotherapy.
- There is an overlap with psychophysiological insomnia among these disorders.
