OBJECTIVE
To clarify the association of reported nightmare recall with polysomnographically defined obstructive sleep apnea (OSA) in a sleep laboratory population.
METHODS
This study included 393 individuals undergoing clinical polysomnography including a general intake questionnaire with questions on dream and nightmare recall frequency. Mean age was 50.5 and a range of 13 to 82 years, with 33% of the sample female and 67% male. Reported dream and nightmare recall were classified as infrequent when reported at less than once a month, or frequent when reported at a frequency greater than once per week.
RESULTS
Mean Apnea-hypopnea Index AHI was 34.9 (std. 32.0) indicating a high frequency of severe (AHI > 30) OSA in this clinical study population. Both AHI and Apnea Index (AI) were significantly higher (p = 0.000) for the grouping reporting infrequent nightmare recall. As the AHI score increased, the percent of participants with frequent nightmare recall decreased linearly.
CONCLUSION
Patients with higher AHI report a lower nightmare frequency, indicating that significant OSA suppresses the cognitive experience of nightmare recall. Depressed nightmare recall may occur secondary to the REMS suppression know to occur in patients with significant OSA.
目的
明确在睡眠实验室人群中，与多导睡眠图定义的阻塞性睡眠呼吸暂停（OSA）相关的报告性梦魇回忆。
方法
本研究纳入 393 名接受临床多导睡眠图检查的个体，其中包括一个一般摄入问卷，其中包含关于梦境和梦魇回忆频率的问题。平均年龄为 50.5 岁，年龄范围为 13 至 82 岁，样本中 33%为女性，67%为男性。报告的梦境和梦魇回忆被分类为不频繁（每月少于一次）或频繁（每周多于一次）。
结果
平均呼吸暂停低通气指数（AHI）为 34.9（标准差为 32.0），表明该临床研究人群中严重（AHI>30）OSA 的频率较高。在报告不频繁梦魇回忆的分组中，AHI 和呼吸暂停指数（AI）均显著更高（p=0.000）。随着 AHI 评分的增加，报告频繁梦魇回忆的参与者百分比呈线性下降。
结论
AHI 较高的患者报告梦魇频率较低，表明严重的 OSA 抑制了对梦魇回忆的认知体验。在有明显 OSA 的患者中，可能会出现 REM 睡眠抑制，从而导致梦魇回忆减少。
