In a previous study, one of the authors (C.C.B.) found isolated sleep paralysis was common in blacks. In this study, conducted by interviews, a recurrent pattern (one or more episodes per month) of isolated sleep paralysis episodes in blacks was described by at least 25 percent of the afflicted sample studied. Frequent episodes were associated with stress, and subjects with isolated sleep paralysis had an unusually high prevalence of panic disorder (15.5 percent). The genetic transmission of sleep paralysis was studied in a large black family, and in addition to stressful environmental factors being associated with the condition, there appears to be a dominant genetic factor associated with the predisposition for developing sleep paralysis. The implications of these findings for stress, anxiety, sleep, and psychophysiologic disorders are discussed.
在之前的一项研究中,作者之一(C.C.B.)发现孤立性睡眠瘫痪在黑人中很常见。在这项通过访谈进行的研究中,至少25%的受研究的患病样本描述了黑人中孤立性睡眠瘫痪发作的复发模式(每月一次或多次发作)。频繁发作与压力有关,患有孤立性睡眠瘫痪的受试者惊恐障碍的患病率异常高(15.5%)。在一个大型黑人家庭中研究了睡眠瘫痪的遗传传递,除了与该病症相关的压力性环境因素外,似乎还有一个与发生睡眠瘫痪易感性相关的显性遗传因素。讨论了这些发现对压力、焦虑、睡眠和心理生理障碍的影响。
