摘　　要：目的:探讨不同部位脑卒中后偏侧忽略对汉字结构认知的影响,为偏侧忽略患者康复策略的制定提供理论依据。方法:收集2008年4月—2009年12月在首都医科大学附属宣武医院住院的不同部位脑卒中后偏侧忽略患者24例,分为3组:其中单纯皮质受损组11例;皮质下损伤组7例;皮质及皮质下均损伤组6例。采用图形临摹、汉字临摹、听写及抄写句子对患者进行检查。结果:①单纯皮质损伤组、皮质下损伤组、皮质及皮质下均损伤组在图形临摹(P<0.001)、汉字临摹(P<0.05)检查中差异有显著性意义;在听写及抄写句子检查中差异无显著性意义(P>0.05)。②图形临摹实验中不同部位脑卒中患者两两比较差异有显著性意义(P<0.05)。③汉字临摹实验中,单纯皮质损伤组与皮质下损伤组(P<0.05)差异有显著性意义;皮质下损伤组与皮质及皮质下均损伤组(P<0.05)差异有显著性意义;单纯皮质损伤组与皮质及皮质下均损伤组(P>0.05)差异无显著性意义。结论:不同部位的脑卒中存在不同程度的汉字结构认知障碍,皮质结构在汉字结构认知上起着关键作用,对汉字的字形编码亦有着重要影响。Objective：To explore the influence of patients＇ unilateral neglect from stroke of different brain area on Chinese character recognition,in order to provide therapeutic strategy for patients.Method：Twenty-four patients with unilateral neglect from stroke of different brain area which included 11 cases of cortex lesions,7cases of subcortex lesions and 6 cases of pooled lesions（both cortex and subcortex） were collected in the Xuanwu Hospital of Capital Medical University from April in 2008 to December in 2009.All objects were evaluated with copying drawing,copying character,copying and dictating sentence.Result：①Differences in three groups were significant in copying drawing（P〈0.001）and copying character（P〈0.05）.But there was no significant difference in copying and dictating sentence.②In copying drawing test,differences in three groups were significant comparing with each other（P〈0.05）.③In copying character test,difference between patients with cortex lesions and subcortex lesions was significant（P〈0.05）;there was significant difference（P〈0.05） between patients with pooled lesions and subcortex lesions;but there was no significant difference（P〈0.05） between patients with pooled lesions and cortex lesions.Conclusion：There were disturbances of different severity of Chinese character recognition in stroke of different brain area.Cortex may be a key point in Chinese character recognition and coding of character pattern as well.
