We emphasize the potential importance of the role of early alterations in sleep and circadian rhythms as a biological marker of early‐onset depression in the preschool period. This builds on findings of the reciprocal relationship between sleep and mood as well as the validity of preschool depression well established in the extant literature. This editorial highlights two recent studies published in JCPP in 2024 defining the duration of clinically impairing depressive symptoms in young children and methods that are now feasible to track daily patterns of sleep and circadian rhythms and show their relation to mood. We propose future studies to investigate these relationships in young children at risk for depression.

社论：幼儿期睡眠和情绪之间的相互作用——抑郁风险的神经标志物尚未得到充分探索


我们强调睡眠和昼夜节律的早期改变作为学龄前早发抑郁症的生物标志物的潜在重要性。这是建立在睡眠和情绪之间相互关系的发现以及现有文献中已确立的学前抑郁症有效性的基础上的。这篇社论重点介绍了最近发表在JCPP到 2024 年，将定义幼儿临床上受损的抑郁症状的持续时间，以及目前可用于跟踪日常睡眠模式和昼夜节律并显示其与情绪关系的方法。我们建议未来进行研究来调查有抑郁风险的幼儿中的这些关系。
