Objective To study the visual attention of mild cognitive impairment patients (MCI)by eyes movement training. Meathods 48 mild cognitive impairment patients were divided into eye movement training group,finger training group and untreated control group by single-blind randomized block method. Then they were trained respectively three months. Event-related potentials (ERPs) were used to measure the face recognition of them before and after training. The amplitude and latency of P3b elicited by target stimuli and P3a elicited by new stimuli of the three said groups were compared and contrasted. Results After training,the amplitude of P1 elicted by novelty stimulus were larger in eye movement training group( (6.78 ± 1.55 ) μV) and in finger training group ( ( 5.43 ± 1.47 ) μV) than untreated control group ( ( 3.09 ± 0.98 ) μV) significantly, especially in the frontal area. The amplitude of P1 elicted by target stimulus were larger in eye movement training group( (6.75 ±2.01 ) μV)than in finger training group( (4.12 ± 1.33 )μV)and untreated control group( (3.45 ± 1.01 )μV)significantly, especially in the frontal area. The amplitude of P3a were larger in eye movement training group( ( 10. 19 ± 3.09)μV ) than in finger training group ( ( 7.57 ± 2.66 ) μV ) and untreated control group ( ( 6.06 ± 2.03 ) μV ) (P ＜ 0.05,P＜0.05) significantly,especially in the frontal area. The latency of P3a were earlier in eye movement training group( (390.67 ±55.03 ) ms) compared to finger training group( (428.55 ± 48.68 ) ms) and untreated control group( (435.89 ± 59.21 )ms)significantly, especially in the frontal region and central parietal area. Conclusion Eyes movement can improve the MCI patients' non-selective attention function, especially in frontal area.The finger execrises have no significant effect on visual attention.
