Narcolepsy falls under which category?

• A. Restless leg syndrome
• B. Insomnia caused by stress
• C. Narcolepsy
• D. Sleep apnea

Answer: (C)

Sleep-disorder classification helps us see narcolepsy as its own distinct sleep-wake disorder. Narcolepsy is defined by persistent daytime sleepiness with irresistible sleep attacks and, in many cases, intrusion of REM sleep features, sometimes accompanied by cataplexy. Because of these defining features, it is treated and managed as its own diagnosis rather than simply a symptom of another problem. The other options describe different sleep problems—restless legs is a movement disorder; insomnia caused by stress is a form of insomnia tied to stress; sleep apnea involves breathing interruptions during sleep. Recognizing narcolepsy as its own category clarifies diagnosis and guides appropriate treatment, such as scheduled daytime naps and wake-promoting medications, with attention to cataplexy if present.
