DESCRIPTION (provided by applicant): In response to RFA-AA-12-006, this application proposes the Duke Research Component of the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA: DUKE) to determine the effects of alcohol use on the developing adolescent brain. Recruited at ages 12 through 21, a high risk enhanced community sample of 170 Duke subjects (N=680 from all sites) will complete a baseline assessment and undergo three annual follow-up assessments in an accelerated longitudinal design. At each visit, a multimodal magnetic resonance imaging (MRI) protocol, comprehensive neuropsychological battery, and assessments of alcohol and other substance use and related problems, mental health symptomatology, and substance use disorder risk factors will be measured. Brain imaging includes state-of-the-art high resolution structural MRI (sMRI), diffusion tensor imaging (DTI), and resting state MRI (rsMRI). The examination of alcohol consequences will focus on structural and functional maturation of brain areas that are actively developing during adolescence, involved in psychological regulation, responsive to rewards, and thought to be vulnerable to toxic alcohol effects. In addition, NCANDA: Duke will collaborate on two supplemental studies. We will collaborate with NCANDA: Pittsburgh in a study utilizing functional MRI to examine cerebral activation during a reward modulated anti-saccade task to study alcohol effects on reward responding and behavioral inhibition. We will also collaborate with NCANDA: UCSD to study a subgroup who will undergo a recovery protocol to attempt to successfully keep youth abstinent from substances for 4-6 weeks and measure recovery of neural and neurocognitive status and function. Studied in the context of risks and baseline brain characteristics, we will determine both the effects of alcohol exposure on the developmental trajectory of the adolescent human brain, and identify preexisting psychobiological vulnerabilities that may put an adolescent at elevated risk for an alcohol use disorder.

描述（由申请人提供）：作为对RFA-AA-12-006的回应，本申请提出了国家青少年酒精和神经发育联盟（NCANDA：DUKE）的杜克研究组成部分，以确定酒精使用对发育中的青少年大脑的影响。招募年龄为12 - 21岁的高风险增强社区样本170名杜克受试者（N=680名来自所有研究中心）将完成基线评估，并在加速纵向设计中进行3次年度随访评估。在每次访视时，将测量多模式磁共振成像（MRI）方案、综合神经心理电池、酒精和其他物质使用及相关问题评估、精神健康障碍学和物质使用障碍风险因素。脑成像包括最先进的高分辨率结构MRI（sMRI）、扩散张量成像（DTI）和静息状态MRI（rsMRI）。酒精后果的检查将集中在结构和功能成熟的大脑区域，在青春期积极发展，参与心理调节，响应奖励，被认为是容易受到有毒酒精的影响。此外，NCANDA：杜克将合作进行两项补充研究。我们将与NCANDA：匹兹堡合作进行一项研究，利用功能性MRI检查奖励调制反眼跳任务期间的大脑激活，以研究酒精对奖励反应和行为抑制的影响。我们还将与NCANDA：UCSD合作研究一个小组，该小组将接受恢复方案，试图成功地使青少年戒除物质4-6周，并测量神经和神经认知状态和功能的恢复。在风险和基线大脑特征的背景下进行研究，我们将确定酒精暴露对青少年大脑发育轨迹的影响，并确定可能使青少年处于酒精使用障碍风险升高的预先存在的心理生物学脆弱性。
