颅脑外伤后患者的智力水平及相关因素研究

A study of intelligence status and related factors in patients with traumatic brain injury

目的 探讨颅脑外伤后患者的智力水平及相关因素。方法 对 55 例颇脑外伤后患者采用修订的韦氏成人智力量表(WAIS- RC)进行测评,并应用自制的颅脑外伤患者人口学及相关资料调查表进行调查,汇总资料进行整理、分析。所有统计分析均使用 SPSS -10.0 软件包完成。结果 颅脑外伤后患者言语智商(VIQ)(69.84±18.58)、操作智商(PIQ)(69.11±19.35)及总智商(FIQ)(66.36±17.58)均低于对照组,差异有极显著性。逐步回归分析揭示,影响言语智商的主要因素为脑外伤后昏迷时间;影响操作智商的主要因素为昏迷时间、年龄及伴有继发性癫痫;影响总智商的主要因素为昏迷时间、伴有脑电图异常、年龄及文化程度。结论 颅脑外伤后患者的智力水平较低,其影响因素涉及多个方面。

Objective To study intelligence status and affecting factors in patients with traumatic brain injury.Methods A total of 55 patients were observed and evaluated by Wechsler Adult Intelligence Scale(WAIS-RC) and self-designed questionnaire.Clinical material was analysed by SPSS-10.0 statistical package.Results VIQ,PIQ and FIQ of patients were 69.84±18.58,69.11±19.35,66.36±17.58,respectively,and significantly lower than those of normal controls.Main influencing factor contributing to VIQ was coma duration after traumatic brain injury.Main influencing factors contributing to PIQ were coma duration ,age,secondary epilepsy and education level.Main influencing factors contributing to FIQ were coma duration,abnormality of EEG,age and education level. Conclusion Intelligence status is lower in patients with traumatic brain injury and its influencing factors are related to many respects.
