To examine sleep disruption in chronic traumatic brain injury (TBI) across 3 aims: (1) to examine differences in self-reported sleep disruption between adults with and without a chronic history of TBI; (2) to query reported changes in sleep after TBI; and (3) to explore the relationship between self-reported sleep disruption and memory failures in daily life.
Community-dwelling participants completed self-report sleep and memory surveys as part of their participation in a larger patient registry.
This study included 258 participants, and half (n = 129) of them have a chronic history of moderate-severe TBI (mean time since injury is 5.1 [SD 6.5] years).
We report descriptive statistics from this matched cross-sectional study on sleep in the chronic phase of injury. We also used planned Wilcoxon ranked-sum tests and exploratory correlations to examine the relationships of sleep disruption with TBI diagnosis, injury chronicity, and memory.
We used the Pittsburgh Sleep Quality Index to measure sleep disruption and the Epworth Sleepiness Scale to measure daytime sleepiness. Participants answered questions about postinjury sleep and responded to the Everyday Memory Questionnaire as a measure of memory failures in daily life.
Individuals with TBI had significantly higher rates of sleep disruption than those without TBI, as measured by the Pittsburgh Sleep Quality Index but not on the Epworth Sleepiness Scale. Sleep disruption in TBI manifested more in sleep quality than quantity. Half of the participants with TBI reported a negative change in sleep postinjury. In an exploratory analysis, sleep disruption was related to memory failure in daily life in the TBI sample.
Sleep disruption persists long after TBI but may be under-recognized in people with chronic TBI. Given that sleep is critical for memory and rehabilitation outcomes well into the chronic phase of injury, steps to improve the identification and management of sleep disruption are needed. Key words:chronic, memory, sleep, traumatic brain injury.
通过三个目标来研究慢性创伤性脑损伤（TBI）患者的睡眠障碍：（1）比较有和无慢性 TBI 病史的成年人的自我报告睡眠障碍差异；（2）查询 TBI 后的睡眠变化报告；（3）探索自我报告的睡眠障碍与日常生活中的记忆失败之间的关系。
居住在社区的参与者完成了自我报告的睡眠和记忆调查，作为他们参与更大的患者登记的一部分。
本研究包括 258 名参与者，其中一半（n=129）有慢性中重度 TBI 病史（受伤后平均时间为 5.1[SD 6.5]年）。
我们报告了这项关于损伤慢性期睡眠的匹配横断面研究的描述性统计数据。我们还使用了计划的 Wilcoxon 秩和检验和探索性相关性来检查睡眠障碍与 TBI 诊断、损伤慢性和记忆的关系。
我们使用匹兹堡睡眠质量指数（PSQI）来衡量睡眠障碍，使用埃普沃思嗜睡量表（ESS）来衡量白天嗜睡。参与者回答了关于受伤后睡眠的问题，并回答了日常生活记忆问卷（ Everyday Memory Questionnaire ）作为日常生活中记忆失败的衡量标准。
与没有 TBI 的参与者相比，TBI 患者的睡眠障碍率明显更高，这是通过匹兹堡睡眠质量指数测量的，但不是通过埃普沃思嗜睡量表测量的。TBI 患者的睡眠障碍更多地表现为睡眠质量而不是数量。一半的 TBI 患者报告说，受伤后睡眠质量下降。在一项探索性分析中，在 TBI 样本中，睡眠障碍与日常生活中的记忆失败有关。
TBI 后，睡眠障碍会持续很长时间，但在慢性 TBI 患者中可能被低估。鉴于睡眠对记忆和康复结果在损伤的慢性阶段至关重要，因此需要采取措施来改善睡眠障碍的识别和管理。关键词：慢性、记忆、睡眠、创伤性脑损伤。
