Asperger syndrome (AS) and autistic disorder are two subtypes of pervasive developmental disorders (PDD), but there has been considerable debate over whether AS and autistic disorder without mental retardation (IQ > or = 70), called high-functioning autism (HFA), are distinct conditions or not. The aim of the present paper was to clarify this issue through a comparison of cognitive function and autistic symptom profiles. Based on the DSM-IV and ICD-10 definitions of language acquisition, 36 age- and IQ-balanced subjects with AS (mean age, 12.8 years; mean full-scale IQ, 98.3) were compared with 37 subjects with HFA (mean age, 12.6 years; mean full-scale IQ, 94.6) on the Japanese version of the Wechsler Intelligence Scales and the Childhood Autism Rating Scale-Tokyo Version (CARS-TV). Compared with the HFA subjects, the AS subjects scored significantly higher on Verbal IQ, Vocabulary, and Comprehension, but scored significantly lower on Coding. Although the total CARS-TV score did not differ significantly between the two groups, AS subjects scored significantly lower (i.e. less abnormal) on Verbal communication and Non-verbal communication than did the HFA subjects. A history of normal language acquisition in early childhood could predict his/her better verbal ability in mid-childhood or later. Autistic cognitive characteristics shared by both AS and HFA subjects appear to support the validity of the current diagnostic classification of PDD.
阿斯伯格综合征(AS)和自闭症障碍是广泛性发育障碍(PDD)的两种亚型,但对于AS以及无智力障碍(智商≥70)的自闭症障碍(称为高功能自闭症,HFA)是否为不同病症一直存在大量争论。本文旨在通过比较认知功能和自闭症症状特征来阐明这一问题。基于《精神疾病诊断与统计手册第四版》(DSM-IV)和《国际疾病分类第十版》(ICD-10)中语言习得的定义,在日本版韦氏智力量表和《儿童自闭症评定量表 - 东京版》(CARS-TV)上,将36名年龄和智商匹配的AS患者(平均年龄12.8岁;平均全量表智商98.3)与37名HFA患者(平均年龄12.6岁;平均全量表智商94.6)进行比较。与HFA患者相比,AS患者在言语智商、词汇和理解方面得分显著更高,但在译码方面得分显著更低。尽管两组之间CARS-TV总分无显著差异,但AS患者在言语交流和非言语交流方面的得分显著低于(即异常程度更低)HFA患者。儿童早期正常语言习得史可预测其童年中期或后期更好的言语能力。AS和HFA患者共有的自闭症认知特征似乎支持了当前PDD诊断分类的有效性。
