目的 研究小脑损伤患者注意网络功能受损的特点.方法 应用注意网络测验,对28例小脑损伤患者和31名健康对照进行注意网络功能的测试.结果 与对照组相比,小脑损伤患者定向效率减低[病例组、对照组分别为(36.32±30.58)、(54.39±22.17)ms],差异有统计学意义(Z=-2.309,P＜0.05);执行控制受到损害[(160.05±83.25)、(93.42±37.41)ms],差异有统计学意义(Z=-3.500,P＜0.01);警觉效率[(35.14±45.59)、(28.81±26.09)ms]与总平均反应时[(797.14±94.11)、(739.90±97.90)ms]的差异无统计学意义.病例组的总平均错误率(6.57%±9.84%)明显高于对照组(3.38%±5.42%,Z=-2.119,P＜0.05).结论 小脑参与了注意网络的认知功能;小脑病变可选择性损害注意网络的定向和执行控制功能,而警觉功能相对保持正常.
目的 研究小腦損傷患者註意網絡功能受損的特點.方法 應用註意網絡測驗,對28例小腦損傷患者和31名健康對照進行註意網絡功能的測試.結果 與對照組相比,小腦損傷患者定嚮效率減低[病例組、對照組分彆為(36.32±30.58)、(54.39±22.17)ms],差異有統計學意義(Z=-2.309,P＜0.05);執行控製受到損害[(160.05±83.25)、(93.42±37.41)ms],差異有統計學意義(Z=-3.500,P＜0.01);警覺效率[(35.14±45.59)、(28.81±26.09)ms]與總平均反應時[(797.14±94.11)、(739.90±97.90)ms]的差異無統計學意義.病例組的總平均錯誤率(6.57%±9.84%)明顯高于對照組(3.38%±5.42%,Z=-2.119,P＜0.05).結論 小腦參與瞭註意網絡的認知功能;小腦病變可選擇性損害註意網絡的定嚮和執行控製功能,而警覺功能相對保持正常.

Objective To investigate the characteristics of attention networks impairment in patients with lesion in the cerebellum.Methods The attention network test was used to compare patients with lesion in the cerebellum(n=28)with normal controls(n=3.1)on the efficiency of three anatomically defined attention networks:alerting,orienting,and executive control. Results The orienting network effect was significantlyworse(Z=-2.309,P＜0.05)in patients with lesion in the cerebellum((36.32±30.58) ms)than in normal controls((54.39±22.17)ms).The executive control network in patients((160.05± 83.25)ms)with lesion in the cerebellinn was worse than those of controls((93.42±37.41)ms,Z= -3.500,P＜0.01).The alerting networks effects was higher in patients((35.14±45.59)ms)than in normal controls((28.81±26.09)ms),without significant difference.The average reaction time was longer in patients than in normal controls,but there was no significant difference.The wrong rate of attention network testwas significantly higher(Z=-2.119,P＜0.05)in patients(6.57%±9.84%)than in normal controls(3.38%±5.42%).Conclusion The patients with lesion in the cerebellum may be selectively impaired of the orienting and executive networks,while the alering network is spared.
