Quizplus · Accepted Answer

Insomnia disorder is a sleep disorder characterized by difficulty falling asleep or staying asleep, or waking up early and being unable to fall back asleep, which causes significant distress or impairment in social, occupational or other important areas of functioning. It is considered a primary disorder because it is not caused by another medical or psychological condition or by substance abuse. Primary hypersomnia is a sleep disorder characterized by excessive sleepiness and prolonged periods of undisturbed sleep, while circadian-rhythm sleep disorders involve disruptions in the timing of sleep and wakefulness due to disturbances in the circadian rhythms that regulate the sleep-wake cycle. Cataplexy is a symptom of narcolepsy, characterized by sudden loss of muscle tone that causes a person to collapse or have difficulty moving.
