The early diagnosis has an very important role in curing dementia. But there was not an effective method to diagnose it until now. In this paper we analyzed the EEG in Alzheimer's disease and normal control groups to compare by nonlinear parameter such as the largest Lyapunov exponent $L_{1}$. We found that patients with Alzheimer's disease have significantly lower$L_{1}$ than normal groups. And we propose the nonlinear analysis of EEG as a useful tool for the early diagnosis of Alzheimer's disease.

The early diagnosis has an very important role in curing dementia. But there was not the effective method to diagnose it until now. In this paper we analyzed the EEG of Alzheimer's disease patients and normal groups by nonlinear methods. In the analysis we calculated the correlation dimensions $D_2$ and the largest Lyapunov exponent $L_1$. We found that patients with Alzheimer's disease have significantly lower $D_2$ and TEX>$L_1$ than normal groups. It means that brains injured by Alzheimer's disease have electrophysiological inactive elements and have decreased chaotic behaviour. We propose the nonlinear analysis of the EEG as a useful tool for the early diagnosis of Alzheimer's disease.

As concerns about dementia patients increase gradually in society, the nursing of them becomes more and more important. For intervening in dementia patients effectively, the most fundamental thing is to understand their characteristics and to increase the ability of assessing them. The assessment data supply us with the foundations of Nursing diagnosis and nursing plan. The reaseons why the assessment data are especially important to dementia patients are as follows; First, dementia patients have great differences among them in intellectual, physical ability. And their condition varies from time to time. Second, the intervention without planning results in the deficiency of consistence, and it rather embarrasses and makes dementia patients uneasy. Third, nursing of dementia patients requires participation of multi-disciplinary team because of characteristics of that disease. The development of an unitary assessment tool is essential for all members of the team to have close relations between them and care for dementia patients. Fully understanding the importance of assessment data, this study investigate the content to be included in the assessment before developing assessment tools to be used in community. It points out that the assessment should include the informations about patients, their family, and main care-giver. And it sets up items that can supply with detailed information on each person. In the future it is necessary to transform the contents of this study to more concrete items and develope the assessment tools for dementia patients. And recording paper for follow up should be supplemented to check any changes in family caring for dementia patients and describe the changes in detail. To make assessment tools is one of the fundamental works in controlling dementia patients. Therefore the official assessment tools should be provided as soon as possible. This study aimed at presenting the guiding principles for developing that assessment tools.

This study was performed to develop cold-heat and deficiency-excess pattern identification for dementia, as well as for standard Korean medicine diagnosis and treatment. Five experts comprised of 4 neuropsychiatrists of Korean medicine and 1 statistician to develop cold-heat and deficiency-excess pattern identification for dementia. We searched studies about pattern identification and selected 507 articles using Oasis search terms provided by the KIOM. As a result, 10 pattern identification research study were recruited. Moreover, we analyzed neuropsychological assessments for dementia that evaluate Behavioral and Psychological Symptoms of Dementia (BPSD) and cognitive function using experts conferences and we selected neuropsychological instruments using pattern identification. Six cold patterns, six heat patterns, ten deficiency patterns, and four excess patterns were identified according to the cold-heat and deficiency-excess pattern identification of dementia. We selected the Caregiver-Administered Neuropsychiatric Inventory and the Korean Mini-Mental State Examination as neuropsychological assessments of dementia, which examine behavioral symptoms and cognitive function, suspectively. We formed positive and negative correlation between Korean medicine pattern identification and neuropsychological assessments for dementia. We developed and suggested a forecast module of pattern identification for dementia. But, it is necessary to perform additional clinical trials to verify its validity and accuracy.

In this paper we propose a system to forecast the dangerous behavior of the dementia patients. Basic idea of our approach is to measure the body movements of the dementia patients using the acceleration sensor. Based on the data measured, warning the care-givers about possible dangerous actions like falling down from the bed and slipping down onto the floor to some extent. The signals measured by the acceleration sensor are processed by a one-chip computer. Based on the diagnosis of the one-chip computer , alert signal is generated to the care-giver by a wire-less signal. The sensor is implemented in a compact body . Applicability of the system is now being examined at a nursing home.

One of the most negative social changes of the last decade is population aging which leads to 19 times more patients with Mild Cognitive Disorder(MCI). It is well established that MCI is the most important state that can prevent dementia with early diagnosis and intervention. However, the social security system for patients with dementia is not working properly due to the coronavirus pandemic and the limited human power. This article proposes a form of workbench and design principles for dementia training programs of extended reality devices. and the findings in this study provide a guide for considering the cognitive and physical and social functions of patients.

There has been a dramatic increase in public awareness regarding dementia during recent years. However, dementia remains a family affair and patients do not receive adequate care in Korea. This study aims to assist patients and their caregivers by establishing Home and Community based Long-Term Care in a city. The data collected for analysis include five main categories: dementia prevalence, limitations of daily activities of patients, burden of caregivers, the services that patient's family want to utilize, the resources that handle dementia in the community. Major findings can be summarized as follows: 1)The prevalence rate of dementia for elderly people is 13.1 per 100 persons. Alzheimer's disease amount to 38.9% of dementia patients and vascular dementia account for 36.7% of them 2)Eight out of ten patients have mild dementia. Almost all patients have normal ADL. IADL, however, shows different picture. In every items of IADL, about 60% of patients reveals some limitations. 3)The proportion of patients who had medical diagnosis is as low as 20%. Families of patients think dementia as normal aging process and medical doctors in the community do not give special concern to dementia patients. 4)Caregivers does not have proper social support. They suffer from long care time, experience large obstacles in respect of health, daily living, and social activity. 5)Health center and Community welfare center have launched some programs-consultation, home-visiting nursing, day care center, voluntary force mobilization and so on-for dementia patients. But they do not perform expected roles and functions because of lack of skilled personnels and inadequate coordination of relevant organizations for dementia care. 6)Families of dementia patients prefer home helper and home-visiting nurse to hospitalization. For the future, however, demand for institution-based long-term services will increase. We develope community dementia care model based on above findings as follows: 1)Health center execute community cardiovascular control program for the prevention of vascular dementia. 2)Refer to epidemiologic characteristics of patients and preference of family, the most urgent task for dementia care in this city is to expand and organize Home and Community based Long-Term Care. 3)For the continuous and comprehensive care, care plan for a patient must be prepared. Case management team should be builded to prepare this plan and coordinate relevant resources. 4)Special long-term care unit for dementia will be needed in a near future. This unit should have multiple functions, such as day-care center, short stay facility, training center for relevant personnels, besides long-term nursing home considering effective care of dementia and efficient operation of the facility. 5)Voluntary workers deserve their due efforts. Incentive mechanisms must be developed to activate voluntary activities.

This study analyzed the contents of the research papers concerning the vascular dementia(VD) recorded in Chinese medical journal published over the period between 1998 and 2000. As a result, the following conclusion was drawn. The Chinese medical category of VD includes Sun-Mang(善忘), Chi-Mae, Jung-Pung-Chi-Mae and so on, and the Major mechanism of the VD is Bon-Heo- Pyo-Sil(state of deficient vital essence and excessive pestilential vapor;本虛標實), Bon(本) includes Sin-Jeong-Heo-Son(腎精虧損), Ki-Hyeol-Hyu-Heo(氣血虧虛) and Pyo(標) includes Dam-Chae-Eo-Jo(痰滯瘀阻), Ki-Chae-Hyeol-Eo(氣滯血瘀), Gan-Yang-Sang-Hang(肝陽上亢). It is mainly used DSM and evidence of brain-vascular disease in brain CT or MRI as the criterion for diagnosis in Western medicine and MMSE, HDS, ADL is used as assistant diagnostic indicator. "Principle of clinical study guidance for treatment of dementia by Chinese medicine, Western medicine"("中藥新藥治療痴呆 病的臨床硏究指導原則") is mainly used as the criterion for diagnosis in Chinese medicine. It is mainly used "Principle of clinical study guidance for treatment of senile disease by Chinese medicine, Western medicine"("中藥新藥治療老年病臨床硏究指導原則"), "Principle of clinical study guidance for treatment of dementia by Chinese medicine, Western medicine" as the criterion for treatment effect evaluation, and score change of MMSE and HDS is used as assistant evaluation indicator. The research papers reported that the use of prescriptions such as Hwan-Chong-Dan(還聰丹), Noi-Hyeol-So-Tong-Gu-Bok-Yaek(腦血疏通口服液), Yik-Gi-Gyo-Nang(益智膠囊), Cheon-Ma-Chok-Gi-Chung-Je(天麻促智沖劑), Sam-Gap-San-Ga-Mi-Bang(三甲散加味方), Seon-Ryong-Gyo-Nang(仙龍膠囊), Seong-Noi-Tang II(醒腦湯II號), Bo-Sin-Geon-Noi-Tang(補腎健腦湯), Ga-Mi-Tong-Gyu-Hyal-Hyeol-Tang(加味通竅活血湯), So-Jo-Yik-Ji-Bang(疏調益智方), Tong-Gyu-Hwal-Hyeol-Tang-Ga-Gam(通竅活血湯加減), Yik-Sin-Seong-Noi-Tang(益腎醒腦湯) led to the high efficacy.

As the incidence and prevalence of dementia increases with our aging population, so does the social burden on our society, which calls for a special emphasis on need for early diagnosis. Thus, efforts are made to prevent dementia and early detection but with current diagnostic measures, these efforts appear futile. As a solution, it is crucial to integrate and standardize healthcare big data and analysis of each index. In order to increase use of large database, the Korea National Assembly passed the Data 3 Act focusing on open-access and sharing of database, but a follow-up legislation is needed a for safer utilization. In this study, we have identified number of foreign of foreign policies through review of prior researches on the topic leading to specific enforcement ordinances tailored to the Data 3 Act for safe access and utilization of database. We also aimed to establish secure process of data collection and disposal as well as governance at the national level to ensure safe utilization of healthcare big data.
