Narcolepsy is

• A. Night Terrors
• B. Sudden Sleep Attacks
• C. Sleepwalking
• D. Inability to Sleep at Night

Answer: (B)

Narcolepsy is a sleep disorder marked by excessive daytime sleepiness and irresistible episodes of falling asleep that can intrude into normal waking activities. The key feature described here is sudden sleep attacks—brief, uncontrollable bouts of sleep that can occur at inopportune times. Some individuals may also experience cataplexy, sleep paralysis, or hypnagogic hallucinations, but the defining clue for this question is the pattern of rapid sleep onset during wakefulness. Night terrors and sleepwalking are parasomnias that arise during certain nocturnal sleep stages and usually involve unusual behaviors or fear during the night, not sudden daytime sleep episodes. Inability to sleep at night describes insomnia, a separate issue involving difficulty initiating or maintaining sleep. So the best description is sudden sleep attacks.
