The purpose of this study was to find out the effects of electroencephalograph (EEG) power and coherence on cognitive function in normal elderly, non-demented elderly with mild cognitive impairment, and demented elderly during working cognition tasks. Forty elderly women (19 demented elderly, 10 non-demented elderly with mild cognitive impairment, 11 norma1 elderly) participated in this study, All subjects performed working cognition tasks with Raven's CPM while EEG signal was recorded, EEGs were measured continuously at rest and during the working cognition task. EEG power and coherence was computed over 21 channels: right and left frontal, central, parietal, temporal and occipital region. We found that there were more correct answers among normal elderly women than in other groups Owing the working cognition task, ${\Theta}$ wave at Fp1, Fp2 and F8, a wave at Fp2, ${\beta}$ wave at Fp1, Fp2. F4 and F8 of the frontal region was increased significantly in the demented elderly group. On the other hand. ${\Theta}$ wave at Fp1, Fp2 and F7, ${\beta}$ wave at Fp1, Fp2, F3 and F7 of the frontal region was increased significantly in the group of non-demented elderly with mild cognitive impairment. In contrast. in the normal elderly group, all of the ${\Theta}$ wave and ${\beta}$ wave at Fp1, Fp2, F3, F4, F7 and F8 of the frontal region (except ${\beta}$ wave at F3) was increased significantly, These results suggest that the nerves in prefrontal and right hemisphere regions were most active in the demented elderly group during problem solving, and the nerves in the prefrontal and left hemisphere lobe were most active in the group of non-demented elderly with mild cognitive impairment. In contrast, me majority of nerves in the frontal region were active in the normal elderly group.

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.

Purpose: The purpose of this study was to identify premorbid personality, depression and disturbing behaviors to provide information for developing nursing interventions for the pre-demented and mild demented elderly living as residents of their community. Method: The survey was conducted through direct interviews using a structured questionnaire in J city. Among the subjects contacted, 89 made appropriate replies to the survey. Result: The subjects' disturbing behaviors were significantly related to premorbid personality and depression. The predictors to disturbing behaviors of the pre-demented elderly were sex, extroversion, neuroticism and conscientiousness. The predictors to disturbing behaviors of the mild demented elderly were agreeableness, depression, sex, conscientiousness, and extroversion. Conclusion: In conclusion, disturbing behaviors of pre-demented elderly and mild demented elderly are affected not only by their premorbid personality but also by their depression. Therefore, it is necessary to encourage and respond to them with understanding their disturbing, behaviors in 'relation to their premorbid personality. In addition. it is important to maintain positive emotion in order to reduce their disturbing behaviors.

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.

The purpose of this study was to develop a cognitive rehabilitation program based on the cognitive activities of the elderly with mild dementia using the weekly care facilities in Daegu city memory and to provide useful welfare services for the elderly with mild dementia. In Korea, there is not much development of community-based integrated intervention program for demented patients who are still in the present situation. The results of this study suggest that the cognitive rehabilitation program for the elderly with mild dementia is suitable to be applied as a group in the case of community based protective editorials and may be a basis for management of mild dementia patients. It seems that there may be differences in the appropriate intervention methods and effects. Therefore, it is expected that the individualized customized strategy will maximize the effect. Therefore, more specific and individualized nursing intervention program should be concurrently developed.

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.

Purpose: The purpose of the study was to develop the day care program for the demented elders and to determine the effects of multiple activity therapies on the physical, emotional, cognitive, social function and physiological indicators of dementia elders in day care center. Method: A total of 13 elders with mild dementia in the data care center were participated. Manual and guideline of data care program was developed. Data care program was composed of movement/exercise, foot massage, music therapy, horticultural therapy, and art therapy. Data care program was performed by trained intervener for 32 weeks. Instruments were physical functioning such as hand grip strength., vital capacity, chiar stand test, sit and reach test, one leg standing, Berg' Balance scale, 6m Walk Velocity, stair climb, ADL, GDS-K, MMSE-K, Integrative Social Functioning Scale, cortisol, Ig A and Ig G. These were measured at the baseline, 16-week, and 32-week post-intervention by the trained nurses. Data were analyzed as Wilcoxon signed rank test. Results: For Hand grip, balance, and vital capacity, there was a significant difference between baseline and 16-week post-intervention(p<.05). For one leg standing, 6m velocity, there was a significant difference between 16-week post-intervention and 32-week post-intervention(p<.05). For Stair climb, there was a significant difference between baseline and 32-week post-intervention(p<.05). For depression and social functioning, there was no significant difference among baseline, 16-week, and 32-week post-intervention. For cognitive functioning, there was a significant difference between baseline and 32-week post intervention(p<.05). There was a significant difference of cortisol, and Ig G between baseline and 32-week post-intervention(p<.05). Conclusion: It would appear that physical fitness, functional performance, ADL, depression, social and cognitive functioning, and physiological indicator of community dwelling elders with dementia can be improved through day care program using multiple stimuli.
