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 =31) on the efficiency of three anatomically defined attention networks; alerting, orienting, and executive control. Results: The orienting network effect was significantly worse (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 cerebellum 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 test was 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.
