A
Circadian rhythm sleep disorder is a sleep disruption that results from a mismatch between body rhythms and environmental demands. Primary hypersomnia occurs when a person sleeps during the night, but naps during the day. Narcolepsy results in repeated attacks of sleep, and obstructive sleep apnea is a breathing-related sleep disorder and not a change in sleep time.
