In this report we present data on the longitudinal evolution of the mental versus the chronological age in 10 fragile X boys diagnosed before the age of 6 years and compare these findings to the longitudinal evolution in children with Down syndrome (6 patients) and Williams syndrome (4 patients). The present findings suggest that the evolution of the velocity of development is more decreased in fra(x) boys compared to the two other groups.
在本报告中,我们呈现了10名6岁前确诊的脆性X综合征男孩心理年龄与实际年龄纵向发展的数据,并将这些结果与唐氏综合征患儿(6例)和威廉姆斯综合征患儿(4例)的纵向发展情况进行比较。目前的研究结果表明,与其他两组相比,脆性X综合征男孩的发育速度下降得更多。
