The majority, but not all, of very preterm-born infants have difficulties with a variety of cognitive functions as children. It is critical to be able to predict as early as possible those who will have difficulties, to be able to direct appropriate interventions.
We are conducting multimodal structural and functional MRI studies in very preterm-born infants and following them with behavioural and neuroimaging assessments until 4 years of age. We are also completing structural and more complex functional imaging in school-aged very preterm-born children.
A number of MRI measures between preterm and term age correlate with outcome at 2 years of age. Functional and structural differences are also seen at school age; examples from these various studies are presented.
Structural and functional studies in preterm-born versus term-born infants and children, particularly if completed longitudinally, provide important information on the evolution of brain-behaviour correlates and can help predict outcome in this high-risk population.
大多数(但非全部)极早产儿在儿童时期会出现各种认知功能障碍。尽早预测哪些婴儿会有困难是至关重要的,以便能够指导采取适当的干预措施。
我们正在对极早产儿进行多模态结构和功能磁共振成像研究,并在他们 4 岁之前进行行为和神经影像学评估。我们还在对学龄期极早产儿进行结构和更复杂的功能成像。
早产儿和足月婴儿之间的许多 MRI 测量值与 2 岁时的结果相关。在学龄期也可以看到功能和结构上的差异;从这些不同的研究中提出了一些例子。
对早产儿和足月婴儿及儿童进行的结构和功能研究,特别是如果进行纵向研究,可提供有关大脑-行为相关性演变的重要信息,并有助于预测这一高危人群的结局。
