短暂性脑缺血发作患者选择性注意功能病例对照研究

A case-control study on the selective attention function of the patients with transient ischemic attack.

目的探讨短暂性脑缺血发作患者的选择性注意功能情况及其影响因素。方法使用Stroop色词测试分别对正常对照组、病例组进行测试,对反映选择性注意功能的冲突刺激反应耗时及错误率、Stroop干扰效应耗时及错误数和每正确反应平均耗时进行比较,并进行单因素及多因素分析,探讨影响短暂性脑缺血发作患者选择注意功能的因素。结果病例组冲突刺激的反应耗时及错误率、Stroop干扰效应耗时及错误数和每正确反应平均耗时均较对照组的差,存在统计学意义(P<0.05)。多因素分析发现高密度脂蛋白、同型半胱氨酸、睡眠、焦虑是影响病例组选择性注意功能的因素。结论短暂性脑缺血发作患者存在选择注意功能障碍,其影响因素不仅有生物学的,还有心理学的。

Objective To explore selective attention function and influencing factors in patients with transient lsehemic attack （T[A）.Methods With the stroop color -word test, the patients and the normal controls were examined by the reaction time, error scores of conflict stimulus and the stroop interfence time, error scores etc. The effective factors were evaluated by single and multiple analysis. Results Reaction time, error score of conflict stimulus and so on, which reflected the selective attention function, had significantly poorer performance in the patients than those in the normal controls （ P 〈 0.05 ）. The factors including high density lipoprotein, homocysteine, sleep conditions and anxiety symptom, effected the TIA patients＇ selective attention function. Conclusion The patients with TIA have selective attention dysfunction which are effected by biological and psychological factors.
