项目摘要
ABSTRACT: This RFA-MH-17-405 “Adult Maturational Changes and Dysfunctions in Emotion Regulation” R01
proposal is designed to study age-related changes in structure and function of a ventral prefrontal cortex
(VPFC) neural system, that subserves emotion processing and regulation, during mid to later adulthood in
individuals with bipolar disorder (BD), compared to healthy control (HC). The emotional dysregulation of BD,
from the extreme positive mood states of manias to negative of depressions, is associated with a great deal of
suffering for those affected and their families, with early mortality owing to one of the highest rates of suicide in
any disorder. Progress has been made by our and other research groups in the identification of abnormalities
in the VPFC brain circuitry that subserves emotional regulation as central to the disorder and its emotional
dysregulation. BD is chronic and often progresses during middle to late adulthood, with an increase in
emotional dysregulation, episode frequency and severity, and symptoms that can become increasingly
refractory to current treatments, increasing suicide risk. However, there has been little previous study of the
brain circuitry changes that underlie this progression. Our exciting new preliminary data implicate progressive
decreases with age in older adults with BD within emotional brain circuitry in the structural integrity of gray
matter regions and their white matter connections, and the ability of nodes within the circuitry to work well
together to regulate emotional responses. In the first such work we are aware of, we plan to build on our
previous neuroimaging and behavioral research in BD to study these age-related emotional brain circuitry
changes in older adults. We propose a 5-year study of age-related changes in mood, emotion regulation and
related symptoms and behaviors using multimodality imaging measures [structural magnetic resonance
imaging (MRI) of gray matter, diffusion tensor imaging (DTI) of white matter, and functional MRI (fMRI)
measures of functional connectivity and of brain responses during implicit and explicit emotion regulation]
comparing BD and HC groups (N=80/group), ages 40-79 years, 50% female;; 64 individuals/group will be
reassessed and rescanned after 2 years to study brain and associated behavioral changes over time. We will
explore relationships between brain aging with sex differences, and with risk factors implicated in progression
including genes and stress, as well as adverse outcomes of progression such as suicide ideation and behavior.
As there has been little study of effects of aging of the VPFC emotional circuitry in healthy individuals, findings
could provide new insights into brain circuitry and emotional regulation in older adults. In addition to the
importance of contributing to understanding BD, as BD is unique in having both elevated and depressive
episodes, its study can provide a model for understanding progressive emotion dysregulation to both negative
and positive extremes. Identification of age-related brain changes in BD could provide novel targets for
intervention and prevention that can be better targeted specifically for older individuals with BD.
摘要:《RFA-MH--17--405》:《成人情绪调节的成熟期改变和功能障碍》《R01》。
该提案旨在研究大脑腹侧和前额叶皮质的结构和功能随年龄的变化。
(VPFC)是一种神经功能系统,它从属于情绪处理和功能调节,在2019年中期到后来的成年阶段。
患有双相情感障碍(BD)的个体与健康的儿童对照(HC)相比,是BD最常见的情绪调节障碍。
从极端和积极的情绪状态到抑郁的负面情绪,都与许多人的生活息息相关。
对于那些受影响的人和他们的家人来说,他们遭受了痛苦,他们的早期死亡是由于他们的自杀率位居世界前列。
任何疾病的无序。我们的研究小组和其他参与了疾病异常识别的研究小组都没有提出过任何问题。
在这方面,VPFC的大脑和电路功能取代了情绪调节功能,成为治疗精神障碍和控制情绪障碍的中枢。
调节失调。BD是一种慢性疾病,通常在中年至成年后期进展缓慢,尤其是BD的发病率显著增加。
情绪调节失调,发作频率和严重程度,以及其他症状,这些症状可能会变得越来越严重。
目前的治疗方法难以奏效,并增加了自杀的风险。然而,以前对这种疾病的研究成果很少。
大脑电路的变化可能是这一进步的基础。我们这一令人兴奋的新的初步数据将牵涉到这一进步。
随着年龄的增长,老年BD患者的年龄会减少,而BD患者的情绪、大脑和电路功能也会随着年龄的增长而减少,而老年人的大脑结构和完整性则不同。
重要的是,这些地区需要它们的白质和连接,并确保这些电路中的节点能够很好地工作。
共同努力来规范我们的情绪反应。在我们不知道的第一个这样的工作中,我们应该计划在我们的基础上继续发展我们的工作。
BD之前的神经成像和行为神经研究团队致力于进一步研究这些与年龄相关的情绪和大脑回路。
老年人的变化。我们建议进行为期5年的研究,研究与年龄有关的情绪、情绪和调节能力的变化。
相关症状和行为,使用多模式成像和措施[结构和磁共振]。
脑灰质的磁共振成像(MRI)、脑白质的弥散张量成像(DTI)、脑白质的功能磁共振成像(FMRI)。
测量大脑的功能和连通性,以及在隐性调控和显性情绪调控过程中做出的反应。
比较BD组和HC组(N=80个/组),年龄40-79岁,女性占50%;;和的个人/组组将不会。
两年后,我们重新评估并重新扫描了大脑,以研究一段时间内的大脑功能和与行为功能变化相关的功能。我们将继续研究。
探索大脑和衰老与性别差异之间的关系,以及与参与疾病进展的风险因素之间的关系。
包括遗传基因和精神压力,以及疾病进展的不良后果,如自杀、构思和行为。
研究结果显示,目前几乎没有人研究VPFC对健康人群情绪回路功能老化的影响。
它可以为老年人的大脑和电路以及情绪调节机制提供新的洞察力。此外,它还可以提供更多的信息。
帮助人们理解BD非常重要,因为BD在治疗中是独一无二的,既有情绪高涨的,也有抑郁的。
插曲,其最新研究报告还可以提供一个新的模型,帮助我们理解进行性的情绪和调节失调,以消除两者的负面影响。
还有一些积极的极端情况。BD患者年龄相关脑功能变化的识别技术可能会为患者提供新的治疗靶点。
干预和预防意味着,可以更好地、有针对性地治疗患有BD的老年人。
