According to ICSD criteria, sleep paralysis (SP) occurs at least once in a lifetime in 40-50% of normal subjects. Variation in the reported incidence could be attributed to the difference in the expression in survey or an influence of cultural background. Some factors assumed to affect the appearance of SP include psychological, biological, developmental, and genetic influences. Sleep onset REM period (SOREMP) is one of the factors which is 'assumed to be related to SP in normal subjects' as well as narcoleptic patients. We conducted an experiment for eliciting SOREMP and SP. Our result indicated a relationship between SOREMP and SP. Polysomnograms during SP were characterized by REM/W stage dissociated states. Other factors which may influence the occurrence of SP are also discussed.
根据国际睡眠障碍分类标准，40%至50%的正常受试者一生中至少会经历一次睡眠瘫痪（SP）。报告发病率的差异可能归因于调查中表达的差异或文化背景的影响。一些被认为会影响睡眠瘫痪出现的因素包括心理、生物、发育和遗传影响。睡眠起始快速眼动期（SOREMP）是被认为与正常受试者以及发作性睡病患者的睡眠瘫痪相关的因素之一。我们进行了一项诱发SOREMP和睡眠瘫痪的实验。我们的结果表明了SOREMP与睡眠瘫痪之间的关系。睡眠瘫痪期间的多导睡眠图特征为快速眼动/清醒阶段解离状态。还讨论了其他可能影响睡眠瘫痪发生的因素。
