目的：探讨癫痫智能碍障的ＷＡＩＳ－ＲＣ智力量表与Ｐ３００潜伏期二者之间的关系。方法：对６６例２０～５０岁癫痫患者（病人）用ＷＡＩＳ－ＲＣ测出全智商（ＦＩＱ），以纯音“ｏｄｄｂａｌ”刺激序列从Ｃｚ引出Ｐ３００（Ｐ３），测其峰潜时（ＰＬ）和波辐（Ａｍｐ）。以５０例年龄、性别、文化水平相匹配的志愿健康人为对照。病人按ＦＩＱ＜９０分（智能减低）和≥９０分（知能正常）分为Ａ和Ｂ两组。然后将Ｐ３各参量（主要为ＰＬ）进行组间统计学分析。结果：Ａ组和Ｂ组与对照组，Ｐ３各参量（ＰＬ，Ａｍｐ）均有显著性差异（Ｐ＜０．０５／０．０１），Ｐ３ＰＬ，Ａ组Ｂ组＞对照组；Ｐ３Ａｍｐ，则反之。ＭｃＮｅｍａｒ测试ＦＩＱ与Ｐ３ＰＬ以Ｘ＋２．０／２．５ＳＤ为上限时，则两种方法结果无显著性差异。Ｋａｐｐａ值测算，ＦＩＱ与上述Ｐ３ＰＬ合理的上限比较时，其Ｋ值依次分别为０．６９、０．６４。结论：对该组病人的智能测验，电生理与心理学两种方法的测试结果，无显著性差异，但Ｐ３ＰＬ正常上限以Ｘ＋２ＳＤ／２．５ＳＤ为宜。两法虽有某种程度的一致性，但并不完全。
Objective: To investigate the relationship between WAIS-RC intelligence scale and P300 latency in epileptic patients with intellectual impairment. Methods: Sixty-six cases of patients with epilepsy between 20 and 50 years old (patients) were tested for total intelligence (FIQ) by WAIS-RC and P300 (P3) was extracted from Cz with “oddbal” Wave (Amp). 50 cases of age, gender and cultural level of volunteer healthy people as a control. Patients were divided into groups A and B according to FIQ <90 (decrease in intelligence) and ≥90 (normal knowledge). Then P3 parameters (mainly PL) for statistical analysis between groups. Results: There was significant difference between group A and group B and control group and group P3 (PL, Amp) (P <0.05 / 0.01), group P3PL, group A and group B> control group . McNemar test FIQ and P3PL with X + 2.0 / 2.5SD as the upper limit, then the two methods showed no significant difference. Kappa value calculation, FIQ and the reasonable upper limit of the above P3PL, the K values were 0.69,0.64, respectively. Conclusion: There is no significant difference between the two groups in the intelligence test, electrophysiology and psychology test, but the upper limit of P3PL with X + 2SD / 2.5SD is appropriate. Although there is some degree of consistency between the two laws, they are not complete.
