Abstract:
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.
