摘要: 目的探讨脑损伤患者的注意维持和警觉功能是否受损及其特征。方法采用连续作业测验(CPT),对27例脑损伤患者和34例年龄及受教育年限匹配的正常成人进行对照研究,以正确数、遗漏数、错误数、平均反应时、末段与首段平均反应时差值(维持差)为指标。结果脑损伤患者的注意维持正确数明显低于对照组(P<0.01),遗漏数明显高于对照组(P<0.01),两组的错误数差异无显著性意义(P>0.05),平均反应时和维持差较对照组明显延长(PP>0.01,P<0.05)。结论 脑损伤患者存在注意维持和警觉功能受损,未发现明显的总支抑制障碍。

Abstract: Objective To investigate the sustained attention and vigilance in patients with brain injury.Methods Twenty-seven patients with brain injury and 34 normal adults who were matched in age and years of education were tested with Continuous Performance Task(CPT) to assess sustained attention and vigilance.The variables included hit number(correct response number),omission number,commission number,and the average reaction time and the difference of reaction time between the first and the last stage.Results The hit number of the patients was much less than that of the control group(P<0.01).The omission number was significantly more than that in the control group(P<0.01),but the commission number did not significantly differ from the control group(P>0.05).The average reaction time and the difference between the reaction time of the first and last stages in patients increased significantly(P<0.01).Conclusion The sustained attention and vigilance are impaired in patients with brain injury.
