Abstract

Sleep disordered breathing (SDB) has its peak incidence in early childhood, but research into the impact of disrupted sleep on learning and overnight memory consolidation has been largely neglected in this population. Hence, we aimed to determine if children with SDB show deficits in learning and overnight consolidation of declarative and procedural memories compared to healthy control (HC) children. Forty-nine children aged 7-16 years (24 SDB, 25 HC) completed a cognitive battery, including two declarative (one verbal, one visual) and one procedural memory task. We manipulated the level of learning (three learning trials or 60% set criterion) on the visual memory task. Recall was assessed at two delays (30 minutes and overnight). Children with SDB underwent an overnight polysomnography sleep study. On declarative visual memory tasks, children with SDB needed more learning trials to reach the set criterion but had intact overnight consolidation. Within the SDB group, more trials to reach the criterion was associated with less time in NREM2 sleep. On the procedural memory task, the opposite pattern of intact learning but reduced overnight consolidation was found. Within the SDB group, worse overnight procedural memory consolidation was associated with less NREM2 sleep and more NREM3 sleep. School-aged children with SDB had deficits in overnight procedural memory consolidation and reduced declarative learning. These findings highlight the adverse consequences of SDB on memory and learning in children and underscore the need to assess recovery of cognitive deficits with treatment in future studies.

轻度睡眠呼吸障碍儿童的学习和夜间记忆巩固缺陷。
睡眠呼吸障碍(SDB)在儿童早期发病率最高,但在这一人群中,关于睡眠中断对学习和夜间记忆巩固影响的研究在很大程度上被忽视了。因此,我们的目的是确定与健康对照(HC)儿童相比,SDB儿童在陈述性和程序性记忆的学习和夜间巩固方面是否存在缺陷。49名7-16岁儿童(SDB 24例,HC 25例)完成了认知电池测试,包括两个陈述性(一个口头、一个视觉)和一个程序性记忆任务。我们在视觉记忆任务中操纵学习水平(三次学习试验或60%设定标准)。召回被评估为两次延迟(30分钟和一夜)。患有SDB的儿童进行了一项夜间多导睡眠图睡眠研究。在陈述性视觉记忆任务中,深发展儿童需要更多的学习试验才能达到设定的标准,但过夜巩固完好。在SDB组中,达到标准的试验次数越多,NREM2睡眠时间越少。在程序性记忆任务中,发现了相反的模式,即完整的学习,但夜间巩固减少。在SDB组中,较差的夜间程序记忆巩固与较少的NREM2睡眠和较多的NREM3睡眠有关。患有SDB的学龄儿童在夜间程序记忆巩固和陈述性学习方面存在缺陷。这些发现强调了SDB对儿童记忆和学习的不良影响,并强调了在未来的研究中评估认知缺陷治疗恢复的必要性。

期刊介绍: The purposes of Child Neuropsychology are to: publish research on the neuropsychological effects of disorders which affect brain functioning in children and adolescents, publish research on the neuropsychological dimensions of development in childhood and adolescence and promote the integration of theory, method and research findings in child/developmental neuropsychology. The primary emphasis of Child Neuropsychology is to publish original empirical research. Theoretical and methodological papers and theoretically relevant case studies are welcome. Critical reviews of topics pertinent to child/developmental neuropsychology are encouraged. Emphases of interest include the following: information processing mechanisms; the impact of injury or disease on neuropsychological functioning; behavioral cognitive and pharmacological approaches to treatment/intervention; psychosocial correlates of neuropsychological dysfunction; definitive normative, reliability, and validity studies of psychometric and other procedures used in the neuropsychological assessment of children and adolescents. Articles on both normal and dysfunctional development that are relevant to the aforementioned dimensions are welcome. Multiple approaches (e.g., basic, applied, clinical) and multiple methodologies (e.g., cross-sectional, longitudinal, experimental, multivariate, correlational) are appropriate. Books, media, and software reviews will be published.
