Which of the following is NOT typically classified as a sleep-wake disorder?

Explanation:
Sleep-wake disorders are defined by problems that are central to the sleep timing, duration, quality, or daytime sleepiness. Insomnia disorder, narcolepsy, and circadian rhythm sleep-wake disorders all focus on these sleep-wake issues as their primary features. Major depressive disorder is a mood disorder, with sleep disturbance as a common but secondary symptom rather than the defining problem. Understanding this distinction explains why major depressive disorder is not typically classified under sleep-wake disorders, even though sleep problems can accompany it.
