脑卒中发病部位和性质与注意力障碍的关系

Relationship between Injury Sites,Pathological Types and Attention in Post Stroke Cognitive Impairment

目的研究不同发病部位和性质的卒中后认知障碍（PSCI）患者注意力障碍特点。方法 2014年6月~2015年6月,用注意力表现测试软件（TAP）对49例PSCI患者在入院l周内进行评定,观测患者完成各项测试的反应时间和反应正确个数。结果警觉度测试中,有无警告音的反应时间左侧缺血组均短于右侧缺血组（Z=-2.32,t=-3.76,P〈0.05）;分散性专注力测试中,右侧缺血组听觉的正确个数多于左侧缺血组（Z=2.42,P〈0.05）。不相容测试及Go/Nogo测试中,左侧出血组反应时间组均短于右侧出血组（Z〉2.32,t=-3.10,P〈0.05）。结论 PSCI患者病灶侧别与注意力障碍有关,但病变性质与注意力障碍关系不明显。

Objective To study the relationship between injury site（right or left） or pathological type（hemorrhage or infarct） and attention impairment in post stroke cognitive impairment（PSCI）. Methods June, 2014 to June 2015, 49 patients with PSCI were assessed with Test of Attentional Performance（TAP） within 1 week of admission. The reaction time and the numbers of correct response were recorded.Results The reaction time of alertness（with or without alarm） was shorter in the patients with left infarction（Z=-2.32, t=-3.76, P〈0.05）,and the correct number of auditory was more（Z=2.42, P〈0.05） than those with right infarction. The reaction time of incompatibility test and Go/Nogo test was shorter in patients with left hemorrhage than those with right hemorrhage（Z〉2.32, t=-3.10, P〈0.05）. Conclusion A trend of lateralization was found in patients with PSCI, rather than in the pathology.
