Objective: There are reports that cognitive training improves cognitive performance in patients with mild cognitive impairment and dementia. However, the research on the effects of cognitive training in the community-dwelling elderly is insufficient. This study aimed to verify the effectiveness of cognitive training in the community-dwelling elderly.
Methods: The participants were community-dwelling elderly aged 60 years or over. We collected demographic data and assessed Korean Version of Montreal Cognitive Assessment (MoCA-K), The Short form of the Geriatric Depression Scale-Korean (SGDS-K), and Geriatric Quality of Life-Dementia (GQOL-D). Cognitive training consisted of performing tasks for multi-cognitive domains. It was a paper- and group-based program, conducted 15 sessions each 60 minute. After the intervention, clinical characteristics were reassessed. Paired t-test, pearson correlation, analysis of covariance (ANCOVA) were performed using R version 3.6.1.
Results: There were 206 participants. 162 participants completed the intervention, and were eligible for analyses. After the cognitive intervention, MoCA-K was improved 2.10±0.61 which was statistically significant (p<0.001). SGDS-K was decreased 0.57±0.46 (p=0.003). GQOL-D was increased 1.65±1.64 (p=0.048). ANCOVA showed that the score change in MoCA-K was not influenced by baseline SGDS-K or baseline GQOL-D score.
Conclusion: Group-and paper-based cognitive training could improve MoCA-K, SGDS-K, and GQOL-D for the communitydwelling elderly. Baseline SGDS-K and GQOL-D scores were not associated with cognitive training effects in the community-dwelling elderly.
