Poor sleep in children is associated with lower neurocognitive functioning and increased maladaptive behaviors. The current study examined the impact of snoring (the most common manifestation of sleep-disordered breathing) on cognitive and brain functioning in a sample of 35 asymptomatic children ages 5-7 years identified in the community as having habitual snoring (SDB). All participants completed polysomnographic, neurocognitive (NEPSY), and psychophysiological (event-related potentials [ERPs] to speech sounds) assessments. The results indicated that sub-clinical levels of SDB may not necessarily lead to reduced performance on standardized behavioral measures of attention and memory. However, brain indices of speech perception and discrimination (N1/P2) are sensitive to individual differences in the quality of sleep. We postulate that addition of ERPs to the standard clinical measures of sleep problems could lead to early identification of children who may be more cognitively vulnerable because of chronic sleep disturbances.
儿童睡眠质量差与神经认知功能较低及适应不良行为增加有关。本研究调查了打鼾（睡眠呼吸障碍最常见的表现）对35名5至7岁无症状儿童认知和大脑功能的影响，这些儿童在社区中被确定为习惯性打鼾（睡眠呼吸障碍）。所有参与者均完成了多导睡眠图、神经认知（NEPSY）和心理生理（对语音的事件相关电位[ERPs]）评估。结果表明，睡眠呼吸障碍的亚临床水平不一定会导致注意力和记忆力标准化行为测量表现下降。然而，言语感知和辨别（N1/P2）的大脑指标对睡眠质量的个体差异敏感。我们推测，在睡眠问题的标准临床测量中加入ERPs可能会有助于早期识别那些因慢性睡眠障碍而在认知上可能更易受影响的儿童。
