Narcolepsy, one of the important causes of hypersomnia, is an under diagnosed sleep disorder. It has a bimodal age of onset around 15 and 35 years. It is characterized by the tetrad of excessive daytime sleepiness, cataplexy, hypnagogic/ hypnopompic hallucinations, and sleep paralysis. Cataplexy is by far the most predictive feature of narcolepsy. Status cataplecticus is the occurrence of cataplexy repeatedly for hours or days, a rare presentation of narcolepsy. This report describes an elderly gentleman with late onset narcolepsy in the sixth decade of life presenting with initial and chief symptom of status cataplecticus.
发作性睡病是引起嗜睡的重要原因之一，是一种未被充分诊断的睡眠障碍。它的发病年龄呈双峰分布，约为 15 岁和 35 岁左右。其特征是白天过度嗜睡、猝倒、入睡前幻觉和睡眠瘫痪四联征。猝倒至今仍是发作性睡病最具预测性的特征。猝倒状态是指猝倒反复发作数小时或数天，是发作性睡病的一种罕见表现。本报告描述了一位 60 多岁的老年男性，起病晚，以猝倒状态为首发和主要症状。
