汉语Broca失语症患者命名障碍机制研究

Mechanism of anomia in Chinese Broca aphasia patients

目的探索Broca失语症患者命名障碍的机制。方法自2014年6月至2015年3月期间，分别对20名Broca失语症患者及正常人行神经心理学测验，包括看图命名测验、词汇辨认、词汇分类与看词指图测验。结果Broca失语症患者看字指图准确率（69.60%）高于看图命名准确率（9.50%），差异有统计学意义（P〈0.05）。结论汉语Broca失语症患者的字形通达语义功能显著优于语义通达语音输出功能，命名障碍主要是由于语音激活困难导致的。

Objective To explore the mechanism of anomia in Broca aphasia patients. Methods Chinese aphasiaexamination method was used to screen Broca aphasia patients. Twenty Broca aphasia patients and 20 normal people were performed neuropsychological tests： picture naming test, word recognition test, vocabulary classification test and reading a map test. Results The accuracy of reading a map test of patients with Broca aphasia （69.60%） was significantly higher than that of picture naming （9.50%, P〈0.05）. Conclusion The glyph conversion semantic function in Chinese Broca aphasia patients is significantly better than function of semantic access speech output. The anomia in Chinese Broca patients with aphasia is mainly due to the difficulties caused by voice activation.
