Preterm birth poses a risk to cognition during childhood. The resulting cognitive problems may persist into young adulthood. The early motor repertoire in infancy is predictive of neurocognitive development in childhood. Our present aim was to investigate whether it also predicts neurocognitive status in young adulthood.
We conducted an explorative observational follow-up study in 37 young adults born at a gestational age of less than 35 weeks and/or with a birth weight below 1200 g. Between 1992 and 1997, these individuals were videotaped up until 3 months' corrected age to assess the quality of their early motor repertoire according to Prechtl. The assessment includes general movements, fidgety movements (FMs), and a motor optimality score (MOS). In young adulthood, the following cognitive domains were assessed: memory, speed of information processing, language, attention, and executive function.
Participants in whom FMs were absent in infancy obtained lower scores on memory, speed of information processing, and attention than those with normal FMs. Participants with aberrant FMs, that is, absent or abnormal, obtained poorer scores on memory, speed of information processing speed, attention, and executive function compared to peers who had normal FMs. A higher MOS was associated with better executive function.
The quality of the early motor repertoire is associated with performance in various cognitive domains in young adulthood. This knowledge may be applied to enable the timely recognition of preterm-born individuals at risk of cognitive dysfunctions.
早产会对儿童期的认知能力造成风险。由此产生的认知问题可能会持续到成年早期。婴儿期的早期运动模式可以预测儿童期的神经认知发展。我们目前的目的是研究它是否也可以预测成年早期的神经认知状态。
我们对 37 名胎龄不足 35 周和/或出生体重低于 1200 克的年轻成年人进行了一项探索性观察随访研究。在 1992 年至 1997 年期间，根据 Prechtl 的方法对这些人进行录像，直到他们校正年龄为 3 个月，以评估他们早期运动模式的质量。评估包括一般运动、烦躁运动（FM）和运动最佳得分（MOS）。在成年早期，评估了以下认知领域：记忆、信息处理速度、语言、注意力和执行功能。
在婴儿期 FM 缺失的参与者在记忆、信息处理速度和注意力方面的得分低于 FM 正常的参与者。FM 异常的参与者，即缺失或异常，在记忆、信息处理速度、注意力和执行功能方面的得分比 FM 正常的同龄人差。较高的 MOS 与较好的执行功能相关。
早期运动模式的质量与成年早期各种认知领域的表现有关。这些知识可以用于及时识别有认知功能障碍风险的早产儿。
