This study aimed to analyze the trajectories of cognitive function and functional disability, and to identify the impacts of socio-demographic factors on the two variables. Based on the assumption that there are differences according to the progress of cognitive impairment, it focused on examining the differences in trajectories of cognitive function and functional disability between two groups: dementia conversion group and dementia non-conversion group among cognitively normal older adults. This study was conducted based on the data from a 3-wave panel study of a sample of 966 Yeoncheon elderly cohort aged 65 and over between 1997 and 2003. Latent growth curve model and multi-group structural equation modeling were used to examine the hypothesis. Results revealed that dementia conversion group exhibited faster rate of cognitive decline as well as lower initial cognitive level. Difference between two groups was not significant in the initial level of functional disability, yet dementia conversion group showed greater degree of deterioration in the functional disability over time than dementia non-conversion group did. In terms of the influence of socio-demographic factors on cognitive function and functional disability, the cognitive decline was more drastic in the female group, whereas functional decline was more apparent for the male group. The level of education in early life had a strong impact on the cognitive function in later life. Based on these findings, practical implication for high risk groups in cognitive function and functional disability were discussed.

The aim of this study is evaluate the effect of a cognitive occupational therapy program on cognitive function, depression and hands function for patients with dementia living in a local community. A cognitive rehabilitation program of 10 weeks focusing on the occupational therapy is conducted from September to December 2012 on 21 patents (experimental group: 12, control group: 9) with dementia who are admitted to nursing homes in a metropolitan region. In the experimental group, the cognitive function, depression level, hand strength, and hand coordination ability is significantly improved after the application of the cognitive program (p<.05). In conclusion, the cognitive occupational therapy program may be a useful intervention for dementia. Because the therapeutic goal for dementia treatment is mainly concentrated on the amelioration of dementia symptoms, thus it is necessary to develop a various cognition training program that can be maintained the patient's residual functional capacity and returned to the social community through the early detection and the early intervention.

The purpose of this study was to investigate feeding difficulty and its influencing factors of elders with dementia in long-term care facilities. Participants were 158 elders with dementia residing in three nursing facilities. Data were collected from Aug. 18 to Sep. 12 in 2014. The feeding difficulty in dementia scale, Korean version-Activities of Daily Living and Mini-Mental State Exam-Korean version were used as instruments. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation and stepwise multiple regression by SPSS 17.0. Mean feeding difficulty score was $0.62{\pm}0.43$(range of 0-2). The highest feeding difficulty item was "patient require close supervision while feeding". The variables influencing the feeding difficulty was ADL(${\beta}=.312$), cognitive function(${\beta}=-.172$) which explained about 20.0% of total variance. The results suggest the need of developing feeding difficulty coping strategy according to dietary behavior phase, In addition, the development and testing the educational program for caregivers to help feeding difficulty of the elders with dementia in long-term facility are recommended.

Objects : To investigate the relationship between the age of onset with the atrophy and the white matter hyperintensities observed in the brain MRI of Alzheimer patients. Methods : The authors measured volumetrically cortical and ventricular brain atrophy and rated semiquantitatively white matter signal hyperintensities in nine presenile and 18 senile Alzheimer patients, who were matched for dementia severity, according to NINCDS-ADRDA criteria and in age-matched 10 presenile and 11 senile control subjects. Results : Presenile Alzheimer patients showed significantly greater cortical and ventricular atrophy indices(p<0.05) but no difference in white matter hyperintensity scores compared to the age-matched control group. On the contrary, senile Alzheimer patients showed significantly greater white matter hyperintensity scores(p<0.05) but no difference in cortical and ventricular atrophy indices compared to the age-matched control group. Conclusion : An earlier onset was related to marked brain atrophy with less white matter lesions and a later onset is related to marked white matter lesions with less brain atrophy in Alzheimer's disease. Our results suggested the passible difference in the pathophysiology between the presenile and the senile-onset Alzheimer's disease.

The number of elderly people with dementia is increasing as fast as the proportion of older people due to aging, which creates a social and economic burden. In particular, dementia care costs, including indirect costs such as increased care costs due to lost caregiver hours and caregivers, have grown exponentially over the years. In order to reduce these costs, it is urgent to introduce a management system to care for dementia patients. Therefore, this study proposes a sensor-based abnormal behavior detection system to manage dementia patients who live alone or in an environment where they cannot always take care of dementia patients. Existing studies were merely evaluating behavior or evaluating normal behavior, and there were studies that perceived behavior by processing images, not data from sensors. In this study, we recognized the limitation of real data collection and used both the auto-encoder, the unsupervised learning model, and the LSTM, the supervised learning model. Autoencoder, an unsupervised learning model, trained normal behavioral data to learn patterns for normal behavior, and LSTM further refined classification by learning behaviors that could be perceived by sensors. The test results show that each model has about 96% and 98% accuracy and is designed to pass the LSTM model when the autoencoder outlier has more than 3%. The system is expected to effectively manage the elderly and dementia patients who live alone and reduce the cost of caring.

This study was performed to investigate the effects of Occupation based Reminiscence therapy on cognitive function, depression, and quality of life in elderly patients with mild dementia. Thirty-one elderly patients with mild dementia underwent Occupation based Reminiscence therapy for 40 minutes per session, once weekly, for 8 weeks. Montreal Cognitive Assessment Korean Version (MoCA-K), Short Form of Geriatric Depression Scale-Korean Version (SGDS-K), and Geriatric Quality of Life-Dementia (GQOL-D) were used to measure cognitive function, depression level, and quality of life, respectively. Mean MoCA-K score increased from $14.62{\pm}5.07$ before intervention to $16.88{\pm}4.55$ after intervention; mean SGDS-K score decreased from $7.28{\pm}4.28$ to $6.10{\pm}4.09$, and mean GQOL-D score increased from $26.05{\pm}5.45$ to $28.55{\pm}5.74$. Furthermore, these positive changes were all statistically significant. Based on the results of this study, it was concluded Occupation based Reminiscence therapy may positively affect cognitive function, depression, and quality of life in elderly patients with mild dementia.

The aim of this study was to investigate the factors influencing nurses' pain management in patients with dementia. A total of 197 nurses were recruited from 30 long-term care hospitals in B city. Data were collected from June 25 to July 15, 2016. Data analysis was performed using the SPSS 22.0 program, which included a t-test, ANOVA, Scheffe test, Pearson's correlation, and multiple regression analyses. The levels of knowledge were low with a score of 10.73 out of 18. The level of attitudes, self-efficacy, barriers and performance were 2.98, 3.34, 2.90, and 4.09, respectively. In addition, there were significant differences in the level of performance depending on the age (p=.046), long-term care (p=.009), and pain education (p=.004). The level of attitudes (r=.21, p=.006), self-efficacy (r=.51, p<.001) and performance were positively correlated with each other. A significant negative correlation was observed between the barriers and performance (r=-.16, p=.035). The meaningful variables that influence the performance were self-efficacy, long-term care, and pain education. These factors were responsible for 30.1%. Therefore, effective programs will be necessary to enhance pain management by improving the self-efficacy and knowledge of pain in dementia patients.

This study aims to find out effects of a tailored occupational activity program(TOAP) on the activities of daily living(ADL), cognitive function, depressive mood, and caregiver burden, who live in the community. Method : From October 2009 to May 2010, the TOAP was applied to 15 dementia patients and 15 of their caregivers, who was visitors of the Y-city Center for Managing Dementia in Gyunggi-do. The TOAP was designed for habituating patients and caregivers to the techniques acquired through goal activities and task and making it capable of being routinized regularly. The TOAP was applied to dementia patients and their cvaregivers twice a week for 7 weeks(one-time home visit, one-time phone inspection), a total of 14 times. Results: Significant differences among pre-test and post-test were found in the AMPS motor skills(1.10±1.14 and 1.34±1.2 respectively) scores, AMPS process skills(0.32±0.55 and 0.77±0.66 respectively) scores, ACL(3.86±0.65 and 4.17±0.64 respectively) scores, MMSE-KC(17.33±4.6 and 19.33±4.97 respectively) scores, GDS(11.73±6.87 and 8.53±7.09 respectively) scores, and caregiver burden(31.80±20.06 and 26.13±18.07 respectively) scores(p<0.05). A significant effect was confirmed from the TOAP which ADL, cognitive function, reduced patient's depression and caregiver burden(p<0.05). Conclusion: From the above results that a TOAP has an effect on the improvement of the ability to ADL, cognitive function and reduced depression and caregiver burden of dementia patients living in community. The present author hopes that, in the future, more diverse community based on tailored occupational activity programs will be developed to improve the functions of dementia patients living in community.
