Abstract

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 in-fluenced 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.
