    学前儿童行为发展水平与脑运动中枢发育关联性研究

    Study on the correlation between preschool children's behavior development level and development of brain motor center

      摘要
    • 摘要:
      目的探讨学前儿童行为发展水平与脑运动中枢发育之间关联性。
      方法在多中心幼儿机构分别随机抽取4组共46名儿童纳入研究对象，编制《学前儿童行为发展测量量表》，由监护人和教师对研究对象的行为发展评分并计算儿童行为发展水平指数（与年满6周岁儿童行为发展水平比较）。研究对象均接受颅脑磁共振功能成像，分别测量行为中枢及其密切相关脑区的神经纤维束等量化测量资料。
      结果学前儿童的行为发展水平指数随着年龄增长而逐渐提高（攻击性行为例外）（P < 0.01），脑白质纤维束弥散张量成像（DTI）显示大龄儿童皮质脊髓束较小年龄组发育更为充分，且多参数的变化规律为FA值与年龄呈正相关（P < 0.01）、平均表观扩散系数（apparent diffusion coefficient，ADC）值与年龄呈负相关（P < 0.01）；各向异性分数（fractional anisotropy，FA）值作为对儿童行为能力的"客观数据"，在一定程度上可以用于对儿童行为能力异常的判断参考。
      结论儿童行为发展水平与大脑运动中枢的发育成熟程度呈正相关，较高的行为发展水平与脑白质神经纤维结构的发育成熟密切关联。

       

      Abstract:
      ObjectiveTo explore the relationship between the behavioral development level of preschool children and development of brain motor center.
      MethodsA total of 46 children were randomly selected from the multi-center child care institutions.The preschool Children's Behavioral Development Measurement Scale was compiled.The scores of the behavioral development of subjects were evaluated by guardian and teachers to calculate the child behavior development index(compared with the level of behavioral development of children over 6 years old).The magnetic resonance imaging of the brain in all subjects were detected to quantitatively measure the nerve fiber bundles of behavioral cortex and related brain areas.
      ResultsThe children's behavioral development index gradually increased with the increasing of age(except for aggressive behavior)(P < 0.01).The results of white matter fiber bundle diffusion tensor imaging(DTI) showed that the development of corticospinal tracts in older children were more fully than that in smaller age group(P < 0.01), and the multi-parameter variation of white matter DTI was positively and negatively correlated with fractional anisotropy fractional anisotropy(FA) value and average apparent diffusion coefficient(ADC) value, respectively(P < 0.01).The FA value acted as an "objective data" of children's behavioural abilities, and could be used as a reference in judging the children's behavioural anomalies to some extent.
      ConclusionsThe level of child behavior development is positively correlated with the developmental level of the brain's motor center.The higher level of behavioral development is closely related to the developmental maturity of the white matter nerve fiber structure.
