This document provides an overview of various sleep disorders including: 1. Dyssomnias are primary sleep disorders involving changes in sleep amount, quality or timing including insomnia, hypersomnia, and narcolepsy. 2. Parasomnias are disorders where sleep physiology or behaviors are affected, such as nightmares. 3. Circadian rhythm sleep disorders result from a mismatch between sleep-wake patterns and environmental demands like jet lag or shift work. 4. Breathing-related sleep disorders interrupt sleep through breathing problems like sleep apnea.
