目的：了解老年糖尿病患者注意搜索反应及认知功能老化的特点。方法：应用计算机软件程序和人机对话方式，测定３２例老年糖尿病患者和３０名正常老年人对数字、字母和汉字三种刺激注意搜索反应的速度和成绩。结果：糖尿病组三种刺激反应时比正常组均明显延长，其中汉字反应时最长、字母反应时次之、数字反应时最短；糖尿病组三种刺激反应错误率与正常组比较无明显差异；糖尿病病程大于１５年组比病程小于１５年组三种刺激反应时均明显延长；糖尿病合并高血压病组与无高血压病组比较三种刺激反应时无明显差异。结论：老年糖尿病患者注意搜索反应速度明显减慢，而注意搜索反应准确性下降不明显
Objective: To understand the elderly diabetic patients pay attention to search reaction and cognitive features of aging. Methods: Using computer software program and man-machine dialogue mode, 32 elderly diabetic patients and 30 normal seniors were tested for the speed and achievement of three stimulus-focused search responses. Results: Compared with the normal group, the response time of diabetic group was significantly longer than that of the normal group, of which the response time was the longest, the alphabetical response time was the second, and the number response time was the shortest. There was no significant difference between the three groups in diabetes mellitus. The course of diabetes more than 15 years than the disease duration of less than 15 years were significantly longer three stimulus response; diabetic hypertensive disease group and no hypertension compared to the three stimuli no significant difference. Conclusion: Elderly patients with diabetes mellitus notice that the speed of search reaction slowed down significantly, while paying attention to the decrease of accuracy of search reaction was not obvious
