项目摘要
ABSTRACT.
Concussions occur at an alarming rate among U.S. schoolchildren, with one in five children experiencing a
concussion by age 16. The number of children visiting emergency departments for concussions annually has
increased by 50% over the past decade, with an estimated cost to the healthcare system of $1 billion/year.
Compared to adults, children experience longer and more severe postconcussive symptoms (PCS). Severity
and duration of PCS, however, vary considerably among children, complicating clinical care and return to learn
and play. Persistent PCS including physical, emotional, and cognitive symptoms, result in increased school
absenteeism, social isolation, and psychological distress. Early PCS diagnosis and access to evidence-based
return-to-health and -school interventions are strongly linked to positive health and academic outcomes. Yet
models to identify children at high risk for persistent PCS are lacking. PCS have been linked to inflammatory
processes occurring within the injured brain. Preliminary evidence suggests that fatigue, another symptom
likely contributing to poor outcomes, is also a biological byproduct of pediatric concussions. Importantly, even
though 73% of children report continuous fatigue after concussion, this symptom is rarely studied along with
other PCS. Prior research has focused on the relationship between inflammatory biomarkers and PCS severity
but has not examined this relationship longitudinally. Acute symptom severity alone, however, is a poor
prognostic of clinical outcomes in concussed children. Symptom severity immediately postinjury does not
explain why at least 25% of children still experience PCS after 1 year or why even children who may appear
asymptomatic still report academic and social challenges months after concussion. To identify which children
are at high risk for persistent PCS and poor health, academic, and social outcomes, research tracking PCS
trajectories and describing school-based impacts across the entire first year postinjury is critically needed. This
proposal will 1) define novel PCS trajectory typologies in a racially/ethnically diverse population of 500 children
with concussion (11–17 years, near equal distribution by sex), 2) identify associations between these
typologies and patterns of inflammatory biomarkers, 3) develop a risk stratification model to identify children at
risk for persistent PCS; and 4) gain unique insights and describe PCS impact, including fatigue, on longer-term
academic and social outcomes. We will be the first to use NIH's symptom science model and patient-reported
outcomes to explore the patterns of fatigue and other physical, cognitive, psychological, emotional and
academic responses to concussion in children over a full year. Our model will enable clinicians and educators
to identify children most at risk for poor long-term health, social, and academic outcomes after concussion.
This work is critical to meeting our long-term goal of developing personalized concussion symptom-
management strategies to improve outcomes and reduce disparities in the health and quality of life of children.

脑震荡在美国学龄儿童中以惊人的速度发生,五分之一的儿童经历了脑震荡
脑震荡到16岁。每年因脑震荡去急诊科就诊的儿童数量
在过去十年中增长了50%,医疗保健系统的估计成本为每年10亿美元。
与成年人相比,儿童经历的脑震荡后症状(PCS)更长、更严重。严重性
然而,PCS的持续时间在儿童中差别很大,使临床护理和重返学习变得复杂

尽管73%的儿童报告脑震荡后持续疲倦,但很少有人将这一症状与

但没有纵向审视这一关系。然而,仅凭急性症状的严重程度是很差的。

迫切需要在受伤后的整个第一年中跟踪和描述基于学校的影响。这
该提案将在500名不同种族的儿童中定义新的PCS轨迹类型
对于脑震荡(11-17岁,按性别几乎平均分布),2)确定这些之间的联系
炎性生物标志物的类型和模式,3)开发风险分层模型以识别儿童

这项工作对于实现我们开发个性化脑震荡症状的长期目标至关重要--
