Sleep walking belongs to which category of sleep disorders?

• A. Circadian Rhythm Disorders
• B. Parasomnias
• C. Insomnias
• D. Hypesomnolence Disorders

Answer: (B)

Sleepwalking is a parasomnia, a class of disorders characterized by abnormal events that occur during sleep. In sleepwalking, a person performs complex behaviors while partially asleep, typically arising from deep non-REM (slow-wave) sleep, with little to no conscious awareness or memory of the event. This distinguishes it from other sleep problems: circadian rhythm disorders involve a misalignment between the internal clock and the environment; insomnias are problems with initiating or maintaining sleep; hypersomnolence disorders are defined by excessive daytime sleepiness despite adequate opportunity to sleep. So sleepwalking fits squarely with parasomnias, which cover unwanted or unusual behaviors that arise during sleep.
