ABSTRACT
Objective: the aim of this study was to investigate the effect of computer-assisted cognitive training in healthy older adults with subjective memory complaints.
Methods: Forty older adults, mean age (standard deviation) = 66.4 (5.6) with subjective memory complaints, were included in this study. Participants were randomly assigned to an integrated psychostimulation program (IPP) (N = 17), a computerized cognitive training (CCT) (N = 12) or a control group (N = 11). The training was applied for 8 weeks (90 min/d, 4 d/week for IPP, and 60 min/d, 4 d/week for CCT). Effectiveness was evaluated with a neuropsychological assessment battery, used before and after the implementation of the cognitive training.
Results: According to the data analysis, with analysis of covariance (ANCOVA), we found a statistically significant change in the majority of the cognitive variables measured before and after the experimental conditions compared with the control group. Although, according to a paired t-test, the IPP was more effective in the improvement of cognitive functioning in the participants. Additionally, a decrease in anxiety symptoms was observed after the cognitive intervention in IPP and CCT conditions.
Conclusion: Our findings suggested that cognitive training of moderate intensity, supported by a web platform, could lead to significant improvements in cognitive and psychological well-being in older people with subjective memory complaints.
