Narcolepsy is characterized by which of the following?

• A. Frequent daytime sleep attacks with cataplexy
• B. Insomnia at night only
• C. Sleepwalking is primary symptom
• D. Excess daytime napping

Answer: (A)

Narcolepsy centers on irresistible daytime sleep attacks, often accompanied by cataplexy—sudden, brief loss of muscle tone triggered by strong emotions. This combination is what sets narcolepsy apart from other sleep issues, making it the best description. Insomnia at night focuses on trouble sleeping rather than daytime sleepiness, so it doesn’t capture the core problem. Sleepwalking is a distinct parasomnia tied to NREM sleep and isn’t the primary feature of narcolepsy. While excessive daytime napping can occur, the defining hallmark is the immediate, frequent daytime sleep attacks with cataplexy, which is why that option is the best choice.
