摘　　要：目的探讨左、右半球急性脑梗死对患者注意功能偏侧化的影响。方法运用偏侧化注意网络试验,分别测试18例健康对照者和36例急性脑梗死患者(左、右侧梗死各18例)两侧大脑半球的警觉、定向和执行控制等注意功能。结果健康对照组在定向功能上右侧视野的反应时长于左侧视野的反应时,差异有统计学意义(t=2.31,P<0.05);而在警觉功能和执行控制功能上,左、右侧视野的反应时差异无统计学意义;右侧大脑半球急性梗死组在定向功能上右侧视野的反应时长于左侧视野的反应时,差异有统计学意义(t=3.46,P<0.01);而在警觉功能和执行功能上,左、右侧视野的反应时差异无统计学意义;左侧大脑半球急性梗死组在警觉功能、定向功能及执行功能上左、右侧视野的反应时差异均无统计学意义。在反应错误率方面3组在警觉功能、定向功能及执行功能上左、右侧视野反应错误率差异均无统计学意义。结论健康对照组和右侧半球梗死组均呈现左侧半球定向功能加工优势;左侧半球梗死导致左侧半球定向功能优势消失,提示左侧半球梗死损伤定向功能。Objective To investigate the effect of left and right hemisphere acute cerebral infarction on the lateralization of attention function. Methods Lateralized attention network test was used to observe the to bilateral cerebral hemisphere on the efficiency of three attentional networks： altering,orienting and executive control in 36 patients with acute cerebral infarction and 18 healthy controls. Results For healthy controls,the response time of the right visual field was significantly longer than that of the left visual field in the orienting function（ t = 2. 31,P〈0. 05）. In the altering function and executive control function,there was no statistically significant difference in response time between the left and right visual fields. For the right hemisphere infarction group,the response time of the right visual field was significantly longer than that of the left visual field in the orienting function（ t = 3. 46,P〈0. 01）. In the altering function and executive control function,there was no statistically significant difference in response time between the left and right visual fields. In the left hemisphere infarction group,there was no statistically significant difference in the response time between the left and right visual fields in terms of altering function,orienting function,and executive control function. There was no statistically significant difference in the error rate of the left and right visual field reaction between the three groups in terms of altering function,orienting function,and executive control function. Conclusion In the healthy control group and the right hemisphere acute cerebral infarction group,the left hemisphere is dominant in the orienting function. In the left hemisphere after acute infarction,the left hemisphere dominance disappeares in the orienting function. It is suggested that left hemisphere infarction have injury to orienting function.
