项目摘要
Project Summary/Abstract
Persistent and symptomatic anxiety during childhood is pathological and is a risk factor for the later development
of stress-related psychopathology. Anxious young girls are particularly at risk, as during the transition to
adolescence the prevalence of anxiety disorders (ADs) and depression markedly increases in females compared
to males. Our work in children demonstrates that persistent and symptomatic anxiety is dimensionally related to
altered function of neural circuits identified to be associated with responses to threat. Additionally, anxiety
symptoms and levels of distress are highly overlapping between children that do and do not meet DSM-5 criteria
for ADs. These findings, along with the risk conferred by early-life anxiety, provide a rationale for studying the
broad range of pathological anxiety in preadolescent girls. In addition to daytime worries and fears, sleep-related
symptoms (e.g. pre-sleep arousal, poor sleep quality) are common in anxiety, occurring in up to 90% of youth
with ADs. It is critical to understand how sleep physiology relates to the pathophysiology of childhood anxiety
because sleep is a homeostatic regulator that is involved in learning and memory consolidation, and also
influences emotion regulation. Here, we will use a translational approach leveraging our nonhuman primate
(NHP) model of pathological anxiety to conduct parallel neuroimaging and EEG sleep studies in preadolescent
girls and preadolescent female rhesus monkeys with pathological anxiety. Using multimodal imaging, hdEEG
sleep recordings, and home sleep EEG data, studies in preadolescent girls with pathological anxiety will explore
hypotheses implicating the basolateral amygdala (BLA) and anterior insula (AI) in mediating altered anxiety-
related daytime neural circuit function as well as alterations in REM and regional slow wave sleep. Studies using
similar methods will be performed in NHPs that will be aimed at causal mechanisms. By chemogenetically
activating BLA or AI neurons prior to sleep, the NHP studies will test the roles of the BLA and AI in mediating the
linkage between alterations in sleep and daytime neural circuit function that are associated with pathological
anxiety. Understanding daytime neural alterations associated with pathological anxiety in relation to disrupted
sleep physiology is highly relevant for elucidating mechanisms underlying childhood pathological anxiety and in
conceptualizing new treatment approaches.
项目摘要/摘要
儿童时期的持续性和症状性焦虑是病理性的,是以后发展的危险因素。
与压力相关的精神病态。焦虑的年轻女孩尤其危险,因为在过渡到
青春期女性焦虑症(ADS)和抑郁症的患病率明显高于女性
对男性来说。我们在儿童中的研究表明,持续性和症状性焦虑在维度上与
被认为与对威胁的反应有关的神经回路功能改变。此外,焦虑
符合和不符合DSM-5标准的儿童之间的痛苦症状和程度高度重叠
为了广告。这些发现,以及早年焦虑所带来的风险,为研究
青春期前女孩的广泛病理性焦虑。除了白天的担忧和恐惧之外,与睡眠有关的
焦虑症状(如睡前唤醒、睡眠质量差)在焦虑中很常见,高达90%的年轻人会出现这种症状
带着广告。了解睡眠生理学与儿童焦虑的病理生理学之间的关系是至关重要的。
因为睡眠是一种体内平衡调节器,参与学习和记忆巩固,而且
影响情绪调节。在这里,我们将使用一种翻译方法,利用我们的非人类灵长类
病理性焦虑(NHP)模型在青春期前进行并行神经成像和脑电睡眠研究
女孩和青春期前的雌性恒河猴患有病理性焦虑。使用多模式成像,hdEEG
睡眠记录和家庭睡眠脑电数据,对患有病理性焦虑的青春期前女孩的研究将探索
杏仁基底外侧核(BLA)和前岛(AI)参与调节焦虑改变的假说--
相关的白天神经回路功能以及快速眼动和局部慢波睡眠的改变。研究使用
将在针对因果机制的NHP中执行类似的方法。通过化学遗传学
在睡眠前激活BLA或AI神经元,NHP的研究将测试BLA和AI在调节睡眠中的作用。
睡眠改变和日间神经回路功能之间的联系与病理相关
焦虑。了解与病理性焦虑相关的日间神经改变与精神错乱的关系
睡眠生理学与阐明儿童病理性焦虑的潜在机制密切相关
构思新的治疗方法。
