Project Summary/Abstract Major depressive disorder (MDD) is among the most prevalent, recurrent, and functionally debilitating of all psychiatric disorders. The incidence of MDD rises sharply during adolescence, and individuals who have an onset of MDD in adolescence tend to have a more chronic and severe course of depression than do those with a later onset. Thus, there is an urgent need to develop effective approaches for early identification, prevention, and intervention for MDD. Experiences of early life adversity (ELA), which affect over 40% of children, are a strong predictor of MDD. Research suggests that one pathway by which ELA increases risk for MDD is through alterations in the structural and functional development of frontolimbic regions implicated in stress reactivity and regulation; however, the direction of these effects and how they unfold over time are not known. Moreover, the biobehavioral mechanisms by which ELA influences neurodevelopment and risk for MDD are not well understood. In this context, sleep disturbances is a significant risk factor for MDD across the lifespan and is an underexplored pathway by which ELA might increase risk for MDD during adolescence. Sleep disturbances tend to increase during adolescence due to a combination of normative biological and psychosocial changes; indeed, over 70% of high-school students report getting insufficient sleep. Emerging research suggests that adolescents with greater sleep disturbances have both attenuated white matter development in tracts that connect frontolimbic regions and heightened frontolimbic reactivity to stress. The overlapping neurobiological and health effects of ELA and sleep disturbances suggest that sleep disturbance is a critical pathway that links ELA to frontolimbic alterations and increased risk for MDD. The proposed research addresses critical gaps in the literature by examining the multivariate and longitudinal effects of ELA, sleep disturbances, and frontolimbic connectivity during adolescence and how these factors predict risk for depression in young adulthood. Leveraging data from a multimethod longitudinal study, the proposed project investigates sleep disturbances as a pathway linking ELA with alterations in frontolimbic development and risk for MDD across adolescence and young adulthood (9-20 years of age). The results of this project will not only increase our understanding of the neurobiological mechanisms by which ELA relates to increased risk for MDD, but will also provide insight into sleep disturbances as a potential target of intervention during adolescence to ameliorate the effects of ELA. Moreover, the proposed training plan will enable the applicant to gain theoretical and methodological expertise in studying the relations among ELA, sleep quality, frontolimbic development, and psychopathology during adolescence, and to develop professional skills necessary to transition to an independent research career. Stanford University, the institution at which the applicant will be training, has experts and resources relevant to all domains of the proposal, making it an ideal training environment for the applicant.

项目总结/摘要 重性抑郁症（MDD）是最普遍，复发，功能衰弱的所有 精神疾病抑郁症的发病率在青春期急剧上升， 在青春期发病的MDD倾向于有一个更慢性和严重的抑郁过程比那些 晚一点发作因此，迫切需要制定有效的办法，以便及早发现、预防、 和MDD的干预。影响40%以上儿童的早期生活逆境（ELA）经历是一种 MDD的强预测因子。研究表明，ELA增加MDD风险的一个途径是通过 与应激反应有关的额边缘区结构和功能发育的改变 然而，这些影响的方向以及它们如何随着时间的推移而展开尚不清楚。此外，委员会认为， ELA影响神经发育和MDD风险的生物行为机制尚不清楚 明白在这种情况下，睡眠障碍是整个生命周期中抑郁症的一个重要风险因素，也是一个 ELA可能增加青春期MDD风险的未充分探索的途径。睡眠障碍 在青春期，由于生理和社会心理变化的共同作用，艾滋病毒/艾滋病的发病率往往会增加; 事实上，超过70%的高中生报告睡眠不足。新的研究表明， 有较大睡眠障碍的青少年既减弱了白色物质的发育， 连接额边缘区和额边缘对压力的反应性。重叠的神经生物学 ELA和睡眠障碍对健康的影响表明，睡眠障碍是一个关键的途径， ELA与额缘改变和MDD风险增加有关。拟议的研究解决了以下方面的关键差距： 通过检查ELA、睡眠障碍和额边缘的多变量和纵向效应， 青少年时期的连接以及这些因素如何预测年轻人患抑郁症的风险。 利用多方法纵向研究的数据，拟议的项目调查睡眠障碍 作为一种通路，将ELA与额边缘发育的改变和青春期MDD的风险联系起来 青年期（9-20岁）。该项目的成果不仅将增加我们对 ELA与MDD风险增加相关的神经生物学机制，但也将提供深入了解 将睡眠障碍作为青春期干预的潜在目标，以改善 ELA此外，拟议的培训计划将使申请人获得理论和方法 研究ELA、睡眠质量、额边缘发育和精神病理学之间关系的专业知识 在青春期，并发展过渡到独立研究所需的专业技能 事业申请人将在斯坦福大学接受培训，该大学拥有专家和资源 与提案的所有领域相关，使其成为申请人理想的培训环境。
