摘　　要：目的探讨帕金森病（ＰＤ）患者在图形和汉字的辨认中是否有困难及其程度。方法用速示器控制呈现速度，观察患者在辨认各种图形和汉字时的成绩。结果ＰＤ患者对图形和汉字的辨认成绩均差于对照组，以图形辨认成绩更差。ＰＤ患者图形辨认成绩与受教育水平无关，而与年龄有关；对图形和汉字辨认的成绩与病期或病程基本上无明显相关，提示导致视认知功能改变与导致运动障碍的脑内过程可能并不完全相同。结论ＰＤ患者对图形和汉字的辨认均受损，以图形辨认受损更明显。Objective Are there any difficulty to discriminate the figures and Chinese characters in patients with PD? Methods 40 patients with PD and 40 age, gender and education matched controls were investigated. The stimuli were presented by tachistoscope. Results The results of PD group was significantly worse than control group both on figure and Chinese character discrimination, and was much more worse on figure discrimination. The results of figure discrimination were related to age in PD group, while it was related to educational level in control group. No correlation between both figure and Chinese character discrimination and stage of disease or clinical course of disease was observed, it suggests that the brain mechanism of motor dysfunction and visual cognitive impairment may be different. Conclusions The performance of PD patients was considerably impaired both on figure and Chinese character discrimination, and was much more worse on figure discrimination.
