It is important to prevent progression of mild cognitive impairment (MCI) to Alzheimer's disease or other dementia. This study was conducted to investigate cognitive-based intervention and its effectiveness for the older patients with MCI through systematic review. Data search was conducted in September 2020, using the Korea Research Information Service (Riss) and KoreaMed. After selection of literatures according to the predefined inclusion criteria, a total of 12 articles were included. It is revealed that the cognitive-based intervention for the older adults with MCI was found to have a positive effect on the various factors including cognitive function, depression, physical health status, quality of life, and communication. However, it is difficult to draw a definite conclusion due to the various intervention strategies and instruments used. Thus, based on the results of this study, we suggest more studies to verify the effectiveness of such programs.

The purpose of this study was to find out whether the cognitive function, depression, and health promotion lifestyle changes are maintained or improved through the dementia prevention program when applying the dementia prevention program along with the daily life management program to the elderly with mild cognitive impairment. The study was conducted from April 1 to August 9, 2019, and 30 elderly people with mild cognitive impairment who participated in the dementia prevention program at the Dementia Safty Center in Seoul were studied. The study found that cognitive function (MMSE-DS) and health promotion lifestyle (HPLP-II) were maintained and improved compared to control groups in the experimental group that voluntarily implemented daily life management programs along with dementia prevention programs, and that depression (SF-GDS) decreased. Therefore, based on the results of this study, in future studies, we hope to develop a variety of voluntary daily life management programs to maintain and improve the effectiveness of the dementia prevention program for a long period of time. I hope that the prospective study will be done.

This study was attempted to confirm whether the color therapy intervention study on the elderly with mild cognitive impairment was effective in cognitive function and depression as a method of meta-analysis. In this study, the size of the effect of cognitive function and depression on the final eight studies of the experimental study was calculated through a domestic database from 2000 to October 2022. As a result, the statistically significant average effect size of the entire study was confirmed. In the test of the difference in effect size between groups, both cognitive function and depression were found to have significant effect sizes. Through this study, it was confirmed that calerotherapy is an effective intervention that can improve cognitive function and alleviate depression in the elderly with mild cognitive impairment. Based on the results of this study, it is necessary to develop an intervention program for the elderly with mild cognitive impairment using calerotherapy.

The purpose of this research is to take a look at the factors that influence the successful aging of the elderly with disability as the aging population grows. For this purpose, psychological and social concepts were defined for successful aging of the elderly with disability. It was also verified that the effects of emotional & social preparation for aging on successful aging of the elderly with disability and mediating effects of social support. The subjects of this study are 506 elderly people with disability who are over the age of 50. They were originally extracted from the 4th main survey and 3rd, 4th additional survey of Korean Retirement and Income Study. For data analysis purposes, SPSS 23.0 and SPSS PROCESS macro v2.16 were used. The results of this study are as followed. Firstly, emotional & social preparation for aging turned out to have a significant direct influence on successful aging the elderly with disability. Secondly, emotional & social preparation for aging has a indirect effect on successful aging through social support. On the basis of the results, this study provided the social welfare policy and practical suggestions to enhance the preparation for aging and social support.

The purpose of this study is to analyze the moderating effect of social support on the effect of the use of social services by the elderly with disabilities on life satisfaction.To this end, the 15th data of the Korean Welfare Panel 2020 were used to verify the characteristics, correlation, and multiple regression analysis of variables related to life satisfaction. The SPSS WIN 25.0 program was used. The survey subjects extracted 684 elderly people with disabilities aged 65 or older, and the use of welfare services was divided into income Service, health Service, home welfare Service, and social participation Service, and the analysis results are as follows. First, it was found that the experience of using welfare services for the elderly with disabilities had a positive (+) effect on life satisfaction. Second, social support showed a moderating effect on the effect of using welfare services for the elderly with disabilities on life satisfaction. Through these results, the necessity of practical intervention measures and development of various programs in social welfare policies that can improve the quality of welfare services for the elderly with disabilities and increase life satisfaction through various social support was suggested.

Aim: This study investigated the association between leisure activities and cognitive impairment in Korean community-dwelling older adults. Methods: Among participants of the 2017 National Survey of Older Koreans, 10,055 (male=4,277, female=5,778) were included in this cross-sectional study. To better identify the association between late-life cognition and leisure activities, individual leisure activities were categorized into 3 types including productive, consumptive, and unclassified activities. Multivariate logistic regression analysis was performed to assess the association between participation in leisure activities and cognitive impairment when controlling for possible covariates evidenced by previous studies. Results: Male participants were more likely to be cognitively impaired than female ones with significant differences in all the covariates. After controlling for confounding variables, involvement in productive leisure activities was found to be associated with cognitive function in both male and female groups, along with age, educational level, depressive symptoms, subjective hearing problems, and occupational status. Conclusion: Involvement in productive leisure activities might be associated with decreased risk of cognitive impairment in later life. Appropriate strategies to encourage older adults to participate in productive leisure activities should be established to help them maintain their cognitive function.

The current study aims to identify the heterogeneous changes of functional disabilities in old age rather than to identify an average longitudinal pattern and to explore the effect of health status and social status as risk factors in functional disability trajectories. The sample consisted of a representative sample of community dwellers aged 65 and older from the Korean Longitudinal Study of Ageing (2006 - 2012) was the focus of the study. Latent Class Growth Analysis was used to identify the functional disability trajectory groups. Variables regarding health status and social status changes by class were identified using multinomial logistic regression. The results showed various change patterns in functional disability, which include independent (78%), stable high (4.4%), steeply increasing (7.1%), slightly increasing (5.5%), and moderate to low (4.7%). Aggravation in depressive symptoms and cognitive functions as well as decline in social participations and social engagements were significant predictors of membership in increasing group of functional disability. The findings provide important initial empirical information to target clinical practice and have implications in the importance of conducting research on groups with different characteristics.

Objectives: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. Methods: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). Results: The control group ($GDS{\leq}9$) when compared with mild ($10{\leq}GDS{\leq}16$) and severe ($17{\leq}GDS$) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted $R^2$=35.6%, p<0.001) and BVRT-A score (adjusted $R^2$=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted $R^2$=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. Conclusion: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.
