摘要
本文对轻微脑功能失调(MBD)患儿的智力状况进行了研讨,介绍了用韦克斯勒儿童智力量表(修订版)为测试方法对112名MBD患儿的智力水平、智力结构分析的结果,认为:(1)MBD患儿的智力水平低于正常儿童,且有小部分(6.25％)患儿的智商可低于正常值的下限(IQ=70);(2)MBD患儿的智力缺陷主要是在一般能力部分,与接受教育的效果关系密切。韦氏儿童智力量表中的言语分量表作为客观反映这一能力的量表,可用以作为诊断MBD的一项指标。把言语量表智商为88定为一个诊断指标值,其漏诊率为0.20,误诊率为0.19,诊断效率为0.80;(3)MBD患儿的智商不随年龄增大而发展,从一个侧面证明本病不能随年龄增大而自愈。
In this paper, the intelligence status of minimal brain dysfunction (MBD) children were studied. The intelligence were determined in 112 MBD Children by wechsler intelligence scale for children-Revised (WISC-R). The result showed that (1) The intelligence of MBD Children is lower than that of healthy children. Part of them (6.25％) are lower than the lowest limit of normal value (IQ=70). (2) Intelligence defect of MBD children affects mainly the general capability which is closely related to the educational effect. This capability is measured objectively by the speech scale of WISC-R. The IQ of speech scale can be used as a diagnostic eriterion of MBD. Taking 88 as the diagnostic standard of that IQ, the missed-diagnosis rate is 0.20, the misdiagnosis rate 0.19 and the diagnostic efficiency 0.80. (3) The IQ of MBD children does not increase with the age, showing that MBD cannot be eured spontaneously when their ages increase.
