PROJECT SUMMARY Offspring of mothers with major depressive disorder (MDD) are at substantially elevated risk for developing depression by early adulthood. Devastatingly, 60% of these high risk (HR) youth will meet criteria for MDD by age 25, versus only 16% of individuals in the general population. Recognized by the 2022 NIMH Strategic Plan, the discovery of a reliable, objective marker of MDD risk is critical for earlier detection to facilitate targeted prevention efforts for HR youth. Across studies, HR offspring exhibit maladaptive reactivity and regulatory responses to negative social-emotional stimuli. During functional magnetic resonance imaging (fMRI) tasks probing negative emotion processing (NEP), youth of depressed, versus nondepressed, mothers consistently exhibit dysfunction in brain networks responsible for adaptive NEP, including salience emotional and cognitive control networks (SEN and CCN). Critically, pilot data from the Early-Stage Principal Investigator provide compelling evidence that SEN-CCN network dysfunction during NEP may represent a brain-based marker of depression among HR youth. However, a mechanistic test of this hypothesis has yet to be evaluated in an adequately powered and demographically distributed sample of HR and low risk (LR) youth followed over a sufficient period to detect the emergence of MDD. The current R01 will employ a novel, multimodal, longitudinal study to test whether functional properties of brain networks supporting NEP predict future depression trajectories among HR and LR youth (Aim 1). In doing so, we will examine whether SEN-CCN dysfunction during NEP changes over time once depression emerges. Clarifying the question of stability is critical to determining whether SEN-CCN dysfunction during NEP is modifiable and may represent a novel MDD treatment target in HR youth (Aim 2). Prior work also shows that HR youth exhibit deficits in NEP across physiological (event-related potentials, ERPs), behavioral, and self-report indices. To determine which risk markers should be prioritized for prevention, an innovative aspect of the proposal will be to test if SEN-CCN function during NEP is superior to other cost-effective markers of risk in predicting youth depression, and whether a multi-indicator model including several units of NEP improves MDD prediction indices (Aim 3). Finally, we will explore how biological sex and puberty interact with neurodevelopmental pathways to predict depression trajectories in HR youth. To achieve these aims, we will recruit 250 youth (with and without with a maternal history of recurrent MDD). At baseline, youth (ages 9-14, 50% female) will be lifetime free of MDD to capture the emergence of depression during a period of elevated MDD risk. At baseline, 12-, and 24- months, youth will complete tasks probing negative social- emotional reactivity and regulation to generate multimodal NEP measures (fMRI, ERPs, behavior). Every 6 months, we will assess youth’s depressive symptoms and diagnoses via online surveys and phone interviews (up to 24 months). Findings will contribute to the discovery of biomarkers that are linked to the development and course of MDD among HR youth, which can be utilized in targeted MDD prevention and intervention studies.

项目概要 患有重度抑郁症 (MDD) 的母亲的后代患抑郁症的风险显着升高 令人震惊的是，60% 的高危 (HR) 青少年将在成年早期达到 MDD 标准。 25 岁，而普通人群中只有 16% 得到 2022 年 NIMH 战略计划的认可， 发现 MDD 风险的可靠、客观标记对于早期检测以促进有针对性的治疗至关重要 在所有研究工作中，HR 后代表现出适应不良反应和监管。 在功能磁共振成像 (fMRI) 任务期间对负面社交情绪刺激的反应。 探究消极情绪处理（NEP）、抑郁症青少年与非抑郁症母亲的一致性 表现出负责适应性 NEP 的大脑网络功能障碍，包括 情感和认知的显着性 至关重要的是，早期首席研究员提供了试点数据。 令人信服的证据表明，NEP 期间 SEN-CCN 网络功能障碍可能代表了基于大脑的标记 然而，这一假设的机制检验尚未得到评估。 对 HR 和低风险 (LR) 青年进行了为期 10 年的跟踪调查，调查对象有足够的权力且按人口统计分布 目前的 R01 将采用一种新颖的、多模式的、纵向的方法来检测 MDD 的出现。 研究测试支持 NEP 的大脑网络的功能特性是否可以预测未来的抑郁症 HR 和 LR 青年的轨迹（目标 1）在此过程中，我们将检查 SEN-CCN 是否存在功能障碍。 一旦出现抑郁症，NEP 就会随着时间而变化。明确稳定性问题对于确定稳定性至关重要。 NEP 期间的 SEN-CCN 功能障碍是否可以改变，并且可能代表 MDD 的新治疗目标 HR 青年（目标 2）还表明，HR 青年在生理（事件相关）方面表现出 NEP 缺陷。 潜力、ERP）、行为和自我报告指数，以确定应优先考虑哪些风险标记。 预防，该提案的一个创新方面将是测试 NEP 期间的 SEN-CCN 功能是否优于 预测青少年抑郁症的其他具有成本效益的风险标记，以及多指标模型是否包括 NEP 的几个单位可以改善 MDD 预测指数（目标 3）。 青春期与神经发育途径相互作用，以预测 HR 青少年的抑郁轨迹。 为了实现这些目标，我们将招募 250 名青少年（在基线时有或没有母亲复发性 MDD 病史）。 青少年（9-14 岁，50% 为女性）将终生免受抑郁症的困扰 MDD 风险升高的时期 在基线、12 个月和 24 个月时，青少年将完成探索负面社交的任务。 情绪反应和调节产生多模式 NEP 测量（fMRI、ERP、行为）。 几个月后，我们将通过在线调查和电话采访来评估青少年的抑郁症状和诊断 （长达 24 个月）。研究结果将有助于发现与发育相关的生物标志物。 人力资源青年MDD课程，可用于有针对性的MDD预防和干预研究。
