Alzheimer's disease is a form of dementia that can be managed by identifying the disease in its initial phases. In recent times, numerous computer-aided diagnostic techniques utilizing magnetic resonance imaging (MRI) have demonstrated promising outcomes in the categorization of Alzheimer's disease (AD). The OASIS MRI dataset was utilized which has 80,000 brain MRI images. It is suggested to resample this dataset as it is highly imbalanced and posed a challenge in preventing bias toward majority class while employing the convolution neural network (CNN) model for classification. This paper examines and extracts patterns and features of 461 patients taken from the OASIS dataset. The research has aimed at utilizing the Base Model of EfficientNetV2B0 with custom classification layers, and simplified custom CNN model, also exploring Multi-class classification across four distinct classes: Non-Demented, Very Mild Demented, Mild Demented, Moderate Demented in addition to binary classification as Non-Demented and treating other classes as demented. Furthermore, different dataset sizes were experimented with 5,000 and 20,000 for each class to be discussed in this paper. The experiment results indicate that EfficientNetV2B0 achieved the accuracy of 98% in binary classification, 99% in multiclass. Whereas custom sequential CNN model in multiclass classification presents the accuracy of 96% for 20,000 dataset size and 98% for 80,000 dataset size.

The purpose of this study was to describe about elders with dementia, their families, and their living environment by visiting the households where demented elders resided. The findings will be used as a basis to develop future individualized adjustment programs for demented elders and their families living in communities. The study participants were 64 demented elders and their families who were registered to a dementia counseling center at Nam-Gu community health center located in Inchon, Korea. Data were collected for two months, from May to June 2001. The length of data collection for each home visit ranged from 1.5 to 2.5 hours. Conclusion are as follows based on these study findings: Those demented elders had more than one chronic health problem in addition to their pre-existing dementia condition. Two thirds of the demented elders were not receiving any specific treatment for dementia. They showed a moderate level of independence in basic ADL, but were mostly residing at home because of lack of ability to perform more delicate and complicate routine daily activities by themselves. In addition, the primary caregivers were not well adjusted to the care-giving activities for their demented family members due to the lack of knowledge and information about dementia. The caregivers were mostly women including daughters-in-law, woman spouses and daughters, over a half of whom perceived their physical and mental health status as poor. Their image toward the demented elders was considerably negative. while their level of knowledge on dementia was moderate. The burden for the care-giving was high, whereas their coping method was passive. As the difference in image toward elderly before and after the onset of dementia in their family member increases, the caregiver burden also increased. The main resource of social support for the caregivers was their children. The caregivers showed high level of needs for knowledge and information on dementia, and day care service was the most preferred type of service by the caregivers. There was lack of safety in the living environments for the demented elders and their families, and in the surrounding environments to prevent dementia-related symptoms. Considering that home-based family care-giving is the most culturally appropriate model of providing care for the demented elders in Korea, we need to develop and apply an individualized adjustment program for the demented elders and their families.

As quickly becoming an ageing society in Korea, this study aims to investigate how family caregivers' burden with demented patients and social supports are related to their health and quality of life, and the interaction of caregiving burden and social supports on caregivers' health and quality of life. The participants were 207 family caregivers (106 females) of demented patients lived in Seoul, Kyunggi, and Chungcheong areas, whose average of age were 51.62 ( SD=9.25). The psychological tests used in this research included the following: Multidimensional Caregiver Burden Inventory, Chon's Physical Symptom Questionnaire, Hahn & Jang's Perceived Health Inventory, Negative Affect Self-Statement Questionnaire, and the Korean Version of Cambell's Subjective Well-being Scale, Social Support Survey in Medical Outcomes Study, and Kwon's Questionnaire for Maladjusted Problems of Demented. Results indicated that caregivers' burden with demented patient related to physical symptoms and depression positively, and perceived health and subjective well-being negatively. Social supports showed moderate effects on influences of caregiving burden in perceived health, depression, and subjective well-being of family caregivers with demented patients. It was identified the possibility of their buffering effect on negative results of caregiving burden with demented patients. Since caregiving burden accounted for the 34% of the variances for family caregivers' physical symptoms and depression, researchers discussed the promotion and intervention of their health and quality of life. Beside of different effects of social supports with level of caregiving burden, with previous studies it was discussed some saliant findings such as family caregivers with patients who showed severe dementia symptoms were perceiving even less supports from others.

The purpose of this study was to test the effects of music therapy on cognitive function and depression in demented old adults. This study was made with one -group in a pre- and post-test design. The subjects were seven demented old adults over, sixty-five years and with mild to moderate cognitive impairment, residing at a nursing home. Music therapy was given by one researcher and one research assistant for thirty to forty minutes twice a week for 4 months. Music therapy was conducted with the subjects both listening and singing with a cassette player and a double-handed drum. In order to evaluate the effects of music, we measured the level of cognitive function and depression at the beginning and at the end of the music therapy session by means of an MMSE- K developed by Kwon and Park and the Depression Inventory developed by Chon. The Data were analyzed using descriptive statistics and a paired t - test analysis using a SPSS PC package. The results are as follows: 1) The subjects of the music therapy showed improvement in cognitive function. The MMSE-K score was significantly increased after music therapy. Especially, memory recall was very significantly. 2) The subjects of the music therapy showed a slight decrease in depression. However, there was no significant difference in the degree of depression between mean scores measured before and after music therapy. The results suggest that music therapy is effective in improving and maintaining cognitive function in demented old adults. And we suggest that long-term music therapy will be required to improve depression in demented old adults. These findings are encouraging the idea that music therapy may improve cognitive impairment.

Objectives: We compared the characteristics of the pain threshold and pain experience between demented group and non-demented group. Methods: This study was part of Gangwon projects for early detection of dementia in 2010. We recruited 8302 local resident ages over 65 years old. Of theses, 1259 people who scored low MMSE were selected and 365 of them completed CERAD-K(Consortium to Establish a Registry for Alzheimer's disease). Finally, 90 in non-demented group and 57 in demented group(mild to moderate Alzheimer's disease) were analyzed. Pain threshold was experimentally measured by pressure algometer and we investigated the pain experience, by Brief pain inventory (BPI), a self-report test. Results: In the demographic characteristics, there are more female, higher ages, lower education in the demented group. There was no significant difference between the two groups in the pain threshold. On the BPI results, 'shoulder pain', 'the number of pain' and 'interference of working' were significantly more prevalent in non-demented group. However, there are no significant differences between the groups in the 'pain severity', 'prevalence of pain' and 'pain treatment'. Conclusions: Demented group report less pain experience but, still perceived pain. It support previous studies that patient with dementia have increased pain tolerance but preserved pain threshold. Thus, active pain assessment and treatment for patients with dementia is needed.

Purpose: This study aimed to explore influencing factors on care burden among family caregivers for elders with dementia living at home. Methods: Participants in this study were 211 family caregivers who were taking care of elders registered at a support center for dementia located in S-gu, Seoul. Data were collected using a structured questionnaire. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression in SPSS WIN 23.0. Results: The care burden of family caregivers was mild to moderate ($40.31{\pm}21.50$) in this study. The factors influencing care burden among family caregivers for elders with dementia were the age, behavioral problems, and dependency in instrumental activities of daily living of demented elderly, in addition to the perceived health status and resting hours of family caregivers. Overall, these factors explained 46.5% of the total variability in care burden in this sample (F=13.01, p<.001). Conclusion: Findings from this study suggest that the characteristics of demented elderly and family caregivers can influence care burden differently. Individually tailored strategies based on the various caregiving contexts need to be developed to reduce the level of care burden among family caregivers for elders with dementia.

Purpose: The purpose of this study is to grasp the welfare service for the demented people staying at home and the service that caregivers want to use. Therefore, we are going to develop a Korean senile dementia-care management model. Method; It analyzed the data of 185 demented people and caregivers, who registered in 16 public dementia care centers in B city since June 2002. Results: 1) The types of services used by the aged people with dementia staying at home were, in the order of frequency of use, the day-care center(26.5%), and home-help service (21.6%). 2). The types of services according to the degree of dementia were as follows; mild cases: home care service (5.4%), moderate cases: day-care service (40.0%) and severe cases: day-care service (26.0%). 3). The caregivers who want to use senile welfare institutions accounted for 23.3%, and the major reason they could not use the institutions was due to their economic situation. 4) The Korean senile dementia care management system must be excuted, considering caregivers' economic state and severity of dementia. Since the system was actively operated, many small sized welfare service institutions showed development. Conclusion: The welfare services appropriate to the severity of dementia should be provided. With the model developed in this study, the dementia management requires sufficient care and should be achieved to reduce the caregivers burden.

The aim of this study was to investigate the effects of occupational therapy with physical exercise on executive function with dementia. For eight elderly persons with mild or moderate dementia, we executed physical exercise with group activity for 10 weeks from April to June, 2012, one times per week, and 50 minutes each time. Before and after the physical activities, the old adults were tested with Verbal Fluency Test(VFT), Trail Making Test A/B(TMT A/B), Clock Drawing Test(CDT). After the physical exercise, the subjects showed significant changes in the score of CDT(p<0.1). In contrast, there was no significant effect in VFT, TMT A. The results of this study show that occupational therapy with physical exercise program for demented elderly people is a useful therapeutic approach by enhancing the their quality of life through improving and maintaining their executive function.

This study was conducted to test the effect of cognitive stimulation training on elderly persons with dementia. The design of the research was one group in pre-test-post-test design. The subjects were nine demented persons over sixty years, with mild to moderate cognitive impairment. Training was administered by research assistants on a one to one basis for thirty to forty minutes, three times a week for eight weeks. In order to evaluate the effect of cognitive stimulation training, we measured cognitive function before and after three training sessions each. Data were analyzed using descriptive statistics and a paired t-test analysis using a spss pc package, The results are as follows: 1) The recipients of the training program showed improvement in overall cognitive functioning. The MMSK - K score, recall levels of concepts, daily tasks, personal past history and performance of word fluency were significantly increased after training. 2) There was a significant improvement in cognitive functioning over the training period: recall levels of concepts, daily tasks, past personal history and performance of word fluency significantly increased over the training period progessively, The results suggest that cognitive stimulation training is effective in improving and maintaining overall cognitive function of elderly persons with dementia.
