Abstract:
Objective:To investigate the effect of the adaptive computerized cognitive training(ACCT) on patients with mild cognitive impairment(MCI).Methods:A total of 114 patients with mild cognitive impairment (53 cases in the treatment group and 61 cases in the observation group) were selected.In the treatment group, routine treatment combined with ACCT were given for 24 weeks, then routine treatment only for 24 weeks, 48 weeks altogether. In the observation group, routine treatment was given for 48 weeks.At week 0, 24, 48, both groups were assessed by scales including: mini-mental state examination (MMSE), Montreal cognitive assessment(MoCA), numerical memory span test, activities of daily living, Hamilton depression scale(HAMD)and Hamilton anxiety scale(HAMA). SAS 9.4 was used for statistical analysis.The data were analyzed by χ 2 test, rank sum test and multi-level model analysis. Results:Interactions between group and time on MMSE( treatment group: 0 week 22.0 (21.0, 23.0), 24 weeks 24.0 (24.0, 25.0), 48 weeks 25.0 (24.0, 26.0); observation group: 0 week 23.0 (21.0, 24.0), 24 weeks 23.0 (21.0, 24.0), 48 weeks 23.0 (21.0, 24.0)), MoCA( treatment group: 0 week 18.0 (17.0, 20.0), 24 weeks 22.0 (20.0, 23.0), 48 weeks 22.0 (20.0, 24.0); observation group: 0 week 19.0 (17.0, 20.0), 24 weeks 19.0 (18.0, 20.0), 48 weeks 19.0 (18.0, 20.0)), IADL( treatment group: 0 week 11.0 (10.0, 13.0), 24 weeks 12.0 (10.0, 12.0), 48 weeks 12.0 (10.0, 12.0); observation group: 0 week 12.0 (11.0, 13.0), 24 weeks 11.0 (10.0, 12.0), 48 weeks 11.0 (10.0, 12.0)), DST-forwards and HAMD scores were significant(all P<0.05), and DST-backwards had significant group main effect ( P<0.05). Further simple effect analysis showed that the influence of group and time on MMSE, MoCA and DST-forwards were statistically significant (all P<0.05), and the influence of time on IADL and HAMD were statistically significant (both P<0.05). Further comparison of the difference between the two groups at each time point: D-value of MMSE, MoCA, DST-forwards, and DST-backwards score in the treatment group were higher than those in the observation group, while D-value of HAMD score was lower than that in the observation group, and the differences were statistically significant (all P<0.05). Conclusion:ACCT may have long term effect on improving the cognitive function and depression of MCI patients.
