DESCRIPTION (provided by applicant): Preterm birth is a major public-health issue because of its increasing incidence combined with the frequent occurrence of subsequent behavioral, neurological, and psychiatric challenges faced by surviving infants. Approximately 10-15% of very preterm children (born < 30 weeks gestational age) develop cerebral palsy, and 30 - 60% of very preterm children experience cognitive impairments. These impairments include visual-motor problems, attentional difficulties, impaired memory, delayed acquisition of language, executive dysfunction, learning disabilities, poor social skills, and higher rates of social withdrawal, anxiety and depression. In addition, an increased prevalence of developmental disorders such as attention deficit/hyperactivity disorder, autism and schizophrenia, has been described in the preterm population. A greater understanding of the mechanisms leading to neurobehavioral impairments in preterm children is an important step in developing strategies for improving clinical outcomes. We have a unique, large cohort of 229 preterm infants (<30 weeks gestation or <1250g) for whom we have developed an extensive perinatal database and obtained advanced magnetic resonance (MR) images at term equivalent. Evaluation of these data has led to novel insights into the nature of the cerebral lesion associated with preterm birth. Importantly, we have maintained ongoing contact with 97% of this cohort during the course of longitudinal neuropsychological follow up. This population now offers a rare opportunity for longitudinal evaluation of the mechanisms of neurobehavioral impairment in association with modern, advanced MR imaging methods. We propose to apply state-of-the-art MR imaging methods to this cohort at 6 years of age in conjunction with neuropsychological evaluation. The MR data will allow us to study the evolution of structural changes in the brain from term equivalent into childhood in both the preterm and term born infants. The techniques will include surface based morphometry (SBM), brain volume measurements (volumetry), and diffusion tensor imaging (DTI). The MR approaches will provide both macroscopic (volumes and SBM) and microscopic (DTI) measures of cerebral development that address different aspects of brain structure and maturation. These will be related to the longitudinal social and neuropsychological evaluations to investigate the relationship of MR measures to neurobehavioral impairments. The longitudinal design will allow us to study both structural abnormalities and compensatory changes over childhood in response to early brain injury. These data will likely provide new understanding of neural recovery and strategies for improving outcomes in preterm infants. PUBLIC HEALTH RELEVANCE: This study is designed to use magnetic resonance (MR) imaging to improve our understanding of the brain injury sustained by prematurely-born infants and how the brain subsequently develops over childhood. The longitudinal design, using both advanced MR imaging and psychological testing, will allow us to study both structural abnormalities and positive adaptive changes over childhood in response to early brain injury. This will assist us in understanding how to reduce the global and specific disabilities that these vulnerable children later face.

描述（由申请人提供）：早产是一个主要的公共卫生问题，因为其发病率不断增加，加上幸存婴儿面临的后续行为，神经和精神挑战的频繁发生。大约10-15%的极早产儿（胎龄< 30周）会患脑瘫，30 - 60%的极早产儿会出现认知障碍。这些障碍包括视觉运动问题、注意力困难、记忆力受损、语言习得延迟、执行功能障碍、学习障碍、社交技能差以及社交退缩、焦虑和抑郁的比例较高。此外，在早产儿人群中，注意力缺陷/多动障碍、自闭症和精神分裂症等发育障碍的患病率有所增加。更好地理解导致早产儿神经行为障碍的机制是制定改善临床结局策略的重要一步。我们有一个独特的，大型队列的229早产儿（<30周妊娠或<1250克），我们已经开发了一个广泛的围产期数据库，并获得了先进的磁共振（MR）图像在长期等效。对这些数据的评估使我们对早产相关脑损伤的性质有了新的认识。重要的是，在纵向神经心理学随访过程中，我们与该队列中97%的人保持了持续的联系。这一人群现在提供了一个难得的机会，纵向评价与现代先进的MR成像方法的神经行为损害的机制。我们建议将最先进的MR成像方法应用于6岁的这一队列，并结合神经心理学评估。MR数据将使我们能够研究早产儿和足月出生婴儿从足月到童年的大脑结构变化的演变。这些技术将包括基于表面的形态测量（SBM），脑容量测量（容量法）和扩散张量成像（DTI）。MR方法将提供大脑发育的宏观（体积和SBM）和微观（DTI）测量，解决大脑结构和成熟的不同方面。这些将与纵向社会和神经心理学评估相关，以调查MR测量与神经行为损伤的关系。纵向设计将使我们能够研究儿童期对早期脑损伤的结构异常和代偿性变化。这些数据可能会为神经恢复和改善早产儿结局的策略提供新的理解。公共卫生关系：这项研究旨在使用磁共振（MR）成像来提高我们对早产儿脑损伤的理解，以及大脑如何在儿童期发育。纵向设计，使用先进的磁共振成像和心理测试，将使我们能够研究结构异常和积极的适应性变化，在儿童期对早期脑损伤的反应。这将有助于我们了解如何减少这些弱势儿童今后面临的全球和具体残疾。
