Circadian-Rhythm Sleep-Wake Disorder

Types: delayed sleep-phase, advanced sleep-phase, irregular sleep-wake, free-running, jet-lag, and shift-work types. Treatment: timed light exposure, melatonin, and scheduled sleep-wake times to re-entrain the circadian clock.

Causes and Pathogenesis

Misalignment of the suprachiasmatic circadian clock with environmental light/social schedules.
