A large percentage of children with Neurofibromatosis Type 1(NF-1) have learning disabilities, often in the realm of reading. Previous studies have indicated that children with NF-1 show a neuropsychological profile similar to idiopathic reading disabilities (IRD); however, studies typically have not subdivided children with NF-1 into those who do and do not have RD (NF+RD and NFnoRD, respectively). The current study examined the cognitive profile of children with NF-1 with and without RD and compared them to children with IRD as well as to typically developing readers (Controls). Findings showed that children with NF+RD performed similarly to children with IRD on phonological, rapid naming, and reading comprehension measures; however, children with NF+RD displayed pronounced visual-spatial deficits as compared to IRD and Control groups. In addition, when comparing the NF-1 groups to each other as well as to the control and IRD groups, the current study reported that there were no oral language differences; lack of findings in the realm of oral language was attributed to the fact that groups were equated on IQ. Overall, findings suggest that a more refined classification of children with NF-1 may be helpful for tailoring academic interventions.
相当大比例的 1 型神经纤维瘤病(NF-1)患儿存在学习障碍,通常在阅读方面。先前的研究表明,NF-1 患儿表现出与特发性阅读障碍(IRD)相似的神经心理学特征;然而,这些研究通常并未将 NF-1 患儿细分为存在 RD 和不存在 RD 的亚组(分别为 NF+RD 和 NFnoRD)。本研究检查了存在 RD 和不存在 RD 的 NF-1 患儿的认知特征,并将其与 IRD 患儿以及正常发育的阅读者(对照组)进行了比较。研究结果表明,NF+RD 患儿在语音、快速命名和阅读理解测试上与 IRD 患儿表现相似;然而,NF+RD 患儿与 IRD 和对照组相比,表现出明显的视觉空间缺陷。此外,在将 NF-1 组相互比较以及与对照组和 IRD 组比较时,本研究报告称,在口语语言方面没有差异;在口语语言领域没有发现差异归因于各组在智商上是匹配的。总体而言,研究结果表明,对 NF-1 患儿进行更精细的分类可能有助于定制学术干预措施。
