What do Sleep-Wake Disorders encompass?

Sleep-Wake Disorders indeed encompass disturbances in sleep patterns. These disorders include a wide range of conditions that affect the ability to sleep well on a regular basis. Common examples include insomnia, sleep apnea, narcolepsy, and parasomnias, all of which specifically pertain to issues with the quantity, quality, or timing of sleep. These disturbances can lead to significant functional impairment during the day, impacting areas such as mood, cognitive function, and overall physical health.

In contrast, behavioral addictions, personality changes, and psychotic episodes are not categorized under Sleep-Wake Disorders. Behavioral addictions relate to compulsive behaviors surrounding activities such as gambling or substance use, while personality changes could point to mood disorders or personality disorders. Psychotic episodes are typically associated with conditions like schizophrenia and involve disruptions in thought processes, perceptions, or feelings. Thus, it is clear that the essence of Sleep-Wake Disorders lies specifically in the various disturbances of sleep.
