项目摘要
Project Summary
Children with autism who receive early intervention services have better outcomes than those who do not. It is
therefore imperative to lower the age of diagnosis. There is strong evidence that there are reliable behavioral
signs/symptoms of the disorder that emerge in the second year of life. However, there is mounting evidence from
our laboratory that there are patterns in the EEG that emerge as early as 3 months that are reliably associated
with autism outcomes at 2-3 years. In this proposal we seek to extend our previous work in two important ways.
First, we will deploy our high-dimensional EEG data collection in a large pediatric primary care clinic, thus
demonstrating the potential scalability of EEG as a biomarker of autism risk. Second, we will focus our efforts
on a population of infants who have historically been underserved and understudied: primarily Black and
Hispanic infants growing up in low-income homes. We will enroll 720 infants over 3 years (240/year), and based
on previous work, anticipate a retention rate of 85%. We will collect resting EEG data at 4, 9 and 12 months in
conjunction with their well-baby visits at the clinic. At 24 months diagnostic outcomes will be evaluated using the
ADOS, developmental measures, and expert clinical judgement. In addition to the EEG assessment in the first
year of life, a general developmental screener will be included (Ages and Stages Questionnaire-3) and indices
associated with a number of non-genetic variables associated with increased autism risk (e.g., infant sex,
parental age, prenatal maternal health, etc.) will be obtained from a demographic questionnaire and medical
records. The specific aims of the project are:
Aim 1: Using a prospective study design in a racially, ethnically and socioeconomically diverse primary
care population, we will identify EEG features measured <1 year of life that are associated with ASD at
2-years of age.
Aim 2: To develop predictive models with EEG biomarkers and other risk factors that reliably predict
later diagnosis of ASD.
Aim 3: To determine the specificity of predictive features for ASD versus other neurodevelopmental
outcomes such as language or cognitive delays.
Our ultimate goal is to create a scalable, practical, neurobiologically-based tool that can be readily integrated
into a pediatric primary care setting, and in so doing, greatly improve our ability to identify autism in the first year.
We believe our approach will allow us to demonstrate scalability of EEG in the primary care setting, develop
usable models for children at greatest risk of delayed diagnosis, and improve our understanding of the underlying
neural mechanisms of idiopathic autism.
项目摘要
接受早期干预服务的自闭症儿童比那些没有接受早期干预服务的自闭症儿童有更好的结果。是
因此,降低诊断年龄势在必行。有强有力的证据表明,有可靠的行为
在生命的第二年出现的疾病的迹象/症状。然而,越来越多的证据表明,
我们的实验室发现,早在3个月大的时候,
在2 - 3岁时自闭症的结果。在本提案中,我们试图以两种重要方式扩展我们以前的工作。
首先,我们将在大型儿科初级保健诊所部署我们的高维EEG数据收集,
证明了EEG作为自闭症风险的生物标志物的潜在可扩展性。二是集中力量
对历史上服务不足和研究不足的婴儿群体:主要是黑人和
在低收入家庭长大的西班牙裔婴儿。我们将招募720名3岁以上的婴儿(240名/年),
在以前的工作中,预计留存率为85%。我们将在第4、9和12个月收集静息EEG数据,
与他们在诊所的健康婴儿访问相结合。在24个月时,将使用
ADOS、发育指标和专家临床判断。除了第一次脑电图评估外,
年龄,将包括一般发育筛选(年龄和阶段问卷-3)和指数
与许多与自闭症风险增加相关的非遗传变量相关(例如,婴儿性别,
父母年龄、产前和产妇健康等)将从人口统计学问卷和医疗调查中获得
记录该项目的具体目标是:
目的1:在种族、民族和社会经济多样化的小学中使用前瞻性研究设计
护理人群中,我们将确定与ASD相关的小于1岁的EEG特征,
2-岁的
目的2:开发具有EEG生物标志物和其他风险因素的预测模型,
ASD的早期诊断
目的3:确定ASD与其他神经发育障碍的预测特征的特异性。
结果,如语言或认知延迟。
我们的最终目标是创建一个可扩展的,实用的,基于神经生物学的工具,可以随时集成
进入儿科初级保健环境,这样做,大大提高了我们在第一年识别自闭症的能力。
我们相信我们的方法将使我们能够证明脑电图在初级保健环境中的可扩展性,
为延迟诊断风险最大的儿童提供可用的模型,并提高我们对潜在疾病的理解。
