RESUMO
BACKGROUND: Dementia cafés for people with dementia and their caregivers are promoted in national dementia policies. The effect of dementia cafés on people with dementia has been reported through narratives of caregivers who participated the dementia cafés. However, evidence derived from the data, which included only people with dementia, is sparse. The aim of this study is to analyze the narratives of people with dementia in peer support meetings in Tokyo where only people with dementia participate, i.e., caregivers were not present. METHODS: People with dementia and older people with subjective cognitive impairment were recruited in our community-based participatory research centre. Based on the qualitative descriptive approach, we conducted a thematic analysis of the field notes, which was made through ethnographical observation of the meetings. RESULTS: Twenty-five meetings were held from November 2018 to March 2020. The cumulative total number of participants was 196. First, the symptomatic problems related to living with dementia were mentioned, which were collectively named under the overarching category of 'Experience of living with dementia.' Second, questions and solutions to the various symptoms were discussed, which were named the 'Quest of Symptoms.' Third, we noted the narrative that reflected on daily life, feelings, and the life that one has led, which were named 'Life story.' Fourth, we noted narratives of how symptoms have improved and their world has expanded, which were named 'Hope.' Fifth and most importantly, narratives about compassion for people with dementia in the past and future, as well as for people of the same generation, were discussed, which were named 'Compassion.' CONCLUSIONS: The lived experiences of people with dementia were revealed. Participants noted they were not just being cared for but exchanging information and exploring the symptoms; in other words, they were resilient. Furthermore, more positive aspects concerning living with dementia were discussed, such as 'Hope' and 'Compassion.' Further research concerning the discourse of people around the participants is necessary to evaluate the situation from multiple perspectives.

AIM: To prevent falls among older adults, healthcare professionals need to assess these individuals from multiple perspectives. This study aimed to group community-dwelling older Japanese people based on their physical, mental, cognitive, and oral functions and comorbidities, and compare the history of falling in these groups. METHODS: Data were obtained from a cross-sectional survey conducted in 2015 among older residents of a ward of Tokyo. For the survey, a questionnaire was distributed to all residents aged ≥65 years without a certificate of long-term care (n = 132,005). Questions were posed concerning respondents' physical, mental, cognitive, and oral functions; comorbidities; and experience with falling in the past year. Cluster and logistic regression analyses were performed. RESULTS: A total of 70,746 participants (53.4%) were included in the analysis. The mean age was 73.6 years old, and 44.9% were male. Four groups were identified in the cluster analysis: the "good general condition group" (n = 37,797, 52.4%), "poor mental function group" (n = 10,736, 14.7%), "moderate physical function group" (n = 13,461, 19.0%), and "poor general condition group" (n = 9,122, 12.9%). A logistic regression analysis with adjusting for socio-demographic characteristics, health behaviors, and fear of falling showed that the odds ratios for the experience of falling within the past year were 1.44 (95% confidence interval: 1.34-1.53), 1.54 (1.44-1.65), and 2.52 (2.34-2.71) in the poor mental function, moderate physical function, and poor general condition groups, respectively, with the good general condition group as the reference. CONCLUSIONS: We classified community-dwelling older adults into four groups based on multiple functions and found possible variations in the risk of falling by group. These findings suggest that such classification may be useful for the prevention of falls.

BACKGROUND: Effective strategies to develop dementia-friendly communities (DFCs) are needed in aging societies. We aimed to propose a strategy to develop DFCs from a Japanese perspective and to evaluate an intervention program that adopted the strategy. METHODS: This study implemented a multi-level intervention that emphasized nurturing community social capital in a large apartment complex in the Tokyo metropolitan area in 2017. We offered an inclusive café that was open for extended hours as a place to socialize and a center for activities that included monthly public lectures. Individual consultation on daily life issues was also available for free at the café. Postal surveys were sent out to all older residents aged 70 years and older in 2016 and 2019. With a one-group pre-test and post-test design, we assessed changes in the proportion of older residents who had social interaction with friends and those who were confident about living in the community, even if they were living with dementia. RESULTS: Totals of 2633 and 2696 residents completed the pre and post-intervention surveys, respectively. The mean age of the pre-intervention respondents was 77.4 years; 45.7% lived alone and 7.7% reported living with impaired cognitive function. The proportion of men who had regular social interaction and were confident about living in their community with dementia increased significantly from 38.8 to 44.5% (p = 0.0080) and from 34.1 to 38.3% (p = 0.045), respectively. Similar significant increases were observed in the subgroup of men living with impaired cognitive function, but not in the same subgroup for women. CONCLUSIONS: The intervention benefitted male residents who were less likely to be involved in the community's web of social networks at baseline. A strategy to create DFCs that emphasizes nurturing community social capital can form a foundation for DFCs. TRIAL REGISTRATION: This study was retrospectively registered in the University hospital Medical Information Network (UMIN) Clinical Trial Registry (registry number: UMIN000038193 , date of registration: Oct 3, 2019).

ObjectivesãWe selected assessment items that can be used to evaluate the physical, mental, and social functions of community-dwelling older people comprehensively and easily, and examined whether these items could predict a future transition to the requirement for nursing care and dementia.MethodsãWe conducted a self-administered mail survey of 4,439 community-dwelling older people, who were not certified as requiring nursing care in 2011. The items for the survey were shortlisted out of a total of 54 items that were selected by referring to existing scales, and the evaluation items were determined by pass rate and factor analysis. The cut-off point of the total scores was estimated by ROC analysis using the certification of requiring long-term care (support level 1 or higher) and level of independence in the daily lives of older people with dementia (independence level I or higher) in 2014 as external criteria. The predictive validity was examined by binomial logistic regression analysis using the cut-off point of the total score and the score of the sub-domains as explanatory variables, and the requirement of nursing care and independence level of dementia in 2014 as objective variables.ResultsãA factor analysis of 1,810 subjects with no deficiencies in the 54 items identified 24 items in five domains (mental health, walking function, Instrumental Activities of Daily Living (IADL), cognitive function, and social support). During the ROC analysis, the cut-off point of the total score was estimated to be 20/21 points (nursing care: AUC 0.75, sensitivity 0.77, specificity, 0.56; dementia: AUC 0.75; sensitivity 0.79, specificity 0.55). The binomial logistic regression analysis showed that persons with a total score of less than 20 points in 2011 were significantly more likely to be certified as requiring nursing care (odds ratio 2.57, 95%CI 1.69-3.92, P<0.01) or show a decline in their independence level of dementia (odds ratio 3.12, 95%CI 1.83-5.32, P<0.01) in 2014. The scores of mental health, walking function, and IADL were significantly associated with certification of requiring nursing care, while walking function and cognitive function were significantly associated with dementia.ConclusionãWe believe that the selected items in this study can successfully predict a transition to needing nursing care and dementia in the future. In the sub-domains, the results suggested an association with physical and mental function, as has been previously reported, but little association with social function.

BACKGROUND: The aim of the present study was to explore factors associated with (i) the inability to attend a follow-up assessment in the community-based participatory research (CBPR) framework; (ii) mortality; and (iii) institutionalization, across a 5-year period among older people with cognitive impairment identified via an epidemiological survey. METHODS: The participants were 198 older people whose score on the Mini-Mental State Examination was below 24, and who were living in our CBPR region in the Tokyo metropolitan area. Baseline data included sociodemographic factors, health-related factors, social factors, and assessments by healthcare professionals. Over the following 5 years we observed what happened to the subjects within the CBPR framework. Bivariate and stepwise multiple logistic regression analyses were performed to explore the factors associated with the inability to attend a follow-up assessment, 5-year mortality, and institutionalization. RESULTS: Participants who did not attend a follow-up assessment tended to live alone. Being older (>80), living with others, frailty, and the need for rights protection and daily living support were associated with increased mortality. Long-term care insurance certification was strongly associated with institutionalization as a natural consequence of the health-care system. Having dementia and low access to doctors were also positively associated with institutionalization. CONCLUSIONS: Older people with cognitive impairment who are living alone are at higher risk of being overlooked by society. To move toward more inclusive communities, the following are recommended: (i) more interventions focusing on older people living alone; (ii) social interventions to detect daily life collapse or rights violations; and (iii) more support to help people with dementia continue living in the community.

BACKGROUND: As Japanese society continues to age, the isolation of older people is increasing, and community living for people with cognitive impairment is becoming more difficult. However, the challenges faced by people with cognitive impairment living in the community have not been fully explored because of methodological difficulties. This study re-accessed people with cognitive impairment identified in a previous epidemiological survey to explore their current situation and the risk factors associated with all-cause discontinuation of community living. METHODS: Under a community-based participatory framework, we examined a high-risk approach for people with cognitive impairment and a community action approach in parallel, to build a dementia-friendly community. For the high-risk approach, we achieved stepwise access to 7614 older residents, which enabled us to select and visit the homes of 198 participants with a Mini-Mental State Examination score < 24 in 2016. In 2019, we re-accessed these individuals. For the community action approach, we built a community space in the study area to build partnerships with community residents and community workers and were able to re-access participants using multiple methods. RESULTS: We found that 126 (63.6%) participants had continued living in the same community, but 58 (29.3%) had discontinued community living. Of these, 18 (9.1%) had died, 18 (9.1%) were institutionalized, 9 (4.5%) were hospitalized, and 13 (6.6%) had moved out of the community. A multiple logistic regression analysis identified the following risk factors associated with discontinuation of community living: being certified under long-term care insurance, needing housing support, and needing rights protection. CONCLUSIONS: Three years after the baseline survey, 29.3% of people with cognitive impairment had discontinued community living. Despite having cognitive impairment or living alone, older people were able to continue living in the community if their needs for housing support and rights protection were met. Both social interventions and medical interventions are important to build age-friendly communities.

BACKGROUND: The study aim was to identify depressed mood and frailty and its related factors in older people during the coronavirus disease 19 pandemic. METHODS: Since 2010, we have conducted questionnaire surveys on all older residents, who are not certified in the long-term care insurance, living in one district of Tokyo municipality. These residents are divided into two groups by birth month, that is those born between April and September and those born between October and March, and each group completes the survey every 2 years (in April and May). Study participants were older residents who were born between April and September and who completed the survey in spring 2018 and in spring 2020, the pandemic period. Depressed mood and frailty were assessed using the Kihon Checklist, which is widely used by local governments in Japan. We had no control group in this study. RESULTS: A total of 1736 residents responded to both surveys. From 2018 to 2020, the depressed mood rate increased from 29% to 38%, and frailty increased from 10% to 16%. The incidence of depressed mood and frailty was 25% and 11%, respectively. Incidence of depressed mood was related to subjective memory impairment and difficulty in device usage, and incidence of frailty was related to being older, subjective memory impairment, lack of emotional social support, poor subjective health, and social participation difficulties. CONCLUSIONS: Older people with subjective memory impairment may be a high-risk group during the coronavirus pandemic. Telephone outreach for frail older people could be an effective solution. We recommend extending the scope of the 'reasonable accommodation' concept beyond disability and including older people to build an age-friendly and crisis-resistant community.

BACKGROUND: Considering the real-world experiences of those with cognitive impairments is important in building a positive community for older people. Community-based participatory research is an important methodology for investigators focused on improving community health. The aim of this study was to 1) investigate factors associated with the continuation of community dwelling among high-risk older people and 2) to create a model of an inclusive community space for older people in the largest housing complex district in Tokyo. METHODS: From 198 residents who completed all three steps (mail, face-to-face, and home-visit) of a previous large-scale epidemiological survey, we identified 66 residents who were at high-risk of moving out of the community. These participants underwent 6 months of regular assessments by experienced researchers to identify the factors associated with continuing to live in the community. We also employed a community action approach to develop a community space for residents in the study district where more than two researchers who were medical professionals served as staff. The services offered by the space were continuously improved according to user feedback. The function of this center was evaluated during interdisciplinary research meetings. RESULTS: After 6 months, among the 66 high-risk residents, 49 people were living in the community and 12 people had moved out of the community. Those who could not continue to live in the community had greater unmet needs in terms of social support, especially daily living support and housing support. In addition, their families perceived a heavier burden of care. Interestingly, dementia diagnosis via the DSM-5, clinical dementia rating, physical health, mental health, and long-term care usage did not predict the outcome. Through discussions with guests, we equipped the space with various services such as coordination of community care and networking with existing organizations. CONCLUSIONS: Merely providing healthcare and long-term care might not be sufficient to support community living in people with cognitive impairments. Daily living support and housing support should be provided in the context of a broad health services package. For this purpose, creating a comfortable community space for residents and community workers is essential.

AIM: To clarify the conditions under which dignity is maintained by reviewing the decision-supporting process for a case. METHODS: We conducted both a longitudinal epidemiological survey and action research in parallel in a large housing complex district in Tokyo, Japan, using the community-based participatory research framework. Through collaboration with community professionals, we supported an isolated elderly man who refused medical intervention for three years until his death. After his passing, we re-examined all of his records, conducted in-depth interviews with the community professionals, and held a conference to review the process of managing this individual. RESULTS: Concerning support for the decision-making, three conclusions were obtained from the data: 1) a decision is not always stated explicitly; 2) a decision should be supported by the team, because mind sometimes changes; and 3) supporting decision-making is a process in itself. For the maintenance of dignity in the medical setting, the following were kept in mind: medical context is not all that is important; supporters should wait for the right moment to intervene, and support should be provided to help the patient keep in touch with other people and the community. CONCLUSIONS: While precisely defining dignity can be difficult, we explored the conditions under which dignity could be maintained by reviewing the decision-supporting process for a single case. Geriatricians may encounter difficult and complex cases such as this in the clinical setting, but guidelines cannot cover such diverse cases.

OBJECTIVES: The purpose of this study is to clarify the influence of social interaction on the effect of a cognitive intervention program using Go. METHODS: A single-blind, randomized controlled trial using a classical board game "Go" was conducted. A total of 72 community-dwelling older adults, without previous experience playing Go, were randomly assigned to three groups: (1) a face-to-face group (FG) in which members attended 12 Go group lessons held once a week; (2) a non-face-to-face group (NFG) in which members individually underwent the same Go lessons as the FG using a tablet computer; or (3) a health education control group (CG). The main outcome variable, working memory, was assessed before and after the interventions using the Visual Memory Span Test (VMST) and the Visual Memory Span Backward (VMSB) task. Go performance and additional cognitive domains were also examined. RESULTS: Analysis of covariance revealed that VMST scores significantly improved after the intervention in both the FG and NFG (both P < .05). Compared with the CG, the effect size of the FG (Cohen's d = 0.89) was greater than that of the NFG (Cohen's d = 0.67). Although VMSB scores significantly improved after the intervention in the FG (P < .05), no significant changes were observed in other groups. CONCLUSIONS: This study showed that Go game could improve visual working memory regardless of social interaction. Furthermore, findings suggested that playing board games face-to-face with others is more effective for cognitive function than playing alone.

BACKGROUND: Despite increasing evidence of an association between childhood socioeconomic disadvantage and cognitive outcomes, such as dementia and cognitive decline, in Western countries, there are no studies on this association from non-Western societies. We investigated the relationship between childhood socioeconomic status (SES) and subjective symptoms of dementia among community-dwelling older Japanese people and examined age and sex variations in this association. METHODS: Data were derived from a cross-sectional survey for all community-dwelling individuals aged 65 years and over in Adachi, Tokyo (n = 132,005). We assessed subjective dementia symptoms using a self-administered dementia checklist, which was validated by comparison with the Clinical Dementia Rating scale. RESULTS: Data from 75,358 questionnaires were analyzed. After adjusting for potential covariates, lower childhood SES was associated with greater likelihood of subjective dementia symptoms. We found a significant interaction between childhood SES and age on subjective dementia symptoms but no interaction between childhood SES and sex. Age-stratified analysis indicated that the association between lower childhood SES and subjective dementia symptoms was stronger in the ≥75 years subgroup than in the 65-74 years subgroup, indicating an effect modification of age on this association. CONCLUSIONS: Our findings suggested that low SES in childhood might have a long-term influence on dementia symptoms in late life and that this influence varied by age. This differential association might be explained by the social and historical context in Japan (ie, World War II, postwar chaos, and high economic growth) that has shaped participants' early experiences.

BACKGROUND: This study explored the relationship between community social capital and cognitive impairment, with a focus on the buffering role of community social capital in the association between educational disadvantage and cognitive impairment in community-dwelling older adults in Japan. METHODS: We used data from two population-based, cross-sectional surveys targeting people aged ≥65 years in a suburban city of the Tokyo metropolitan area (n = 897; 49.8% men; average age = 74.4 years). Social capital included social support (emotional and instrumental support) and the strength of social networks (neighborly ties). To create district-level social capital indicators, we aggregated individual responses on social capital within each district. The Mini-Mental State Examination, Japanese version was used for the assessment of cognitive function. RESULTS: Using multilevel logistic regression analysis, we found that lower amounts of district-level emotional and instrumental support were associated with a greater likelihood of cognitive impairment among men. For women, district-level emotional support was associated with a greater likelihood of cognitive impairment. Additionally, a strong district-level social network buffered the relationship between low education and cognitive impairment in both sexes. CONCLUSIONS: Community social capital appears to have a protective role in determining cognitive function in old age. Our findings may facilitate the development of new community-based strategies to combat dementia.

AIM: Although a dementia-friendly community is a global goal, community-dwelling persons with dementia continue to have unmet care needs. The aim of this study was to explore the characteristics of persons who experience anxiety about the possibility of not receiving proper dementia care should they need it in the future. METHODS: A questionnaire was mailed to all residents aged 65 years or older (n = 132 005) living in one Tokyo district. The questionnaire included an item that measured anxiety about the possibility of not receiving proper dementia care as well as items about sociodemographic variables, depressive symptoms, frailty, housebound status, socioeconomic status, social support, access to a general practitioner (GP), and experience of dementia care. RESULTS: Of the 74 171 participants who responded to the anxiety item, 58 481 (78.8%) reported anxiety about the possibility of not receiving proper dementia care should they need it in the future. Simultaneous multiple logistic regression analysis indicated that factors associated with this anticipatory anxiety were depressive symptoms, frailty or prefrailty, being female, not being currently socioeconomically disadvantaged, not having someone who can take you to the hospital when you do not feel well, being younger (65-74 years), being married, not trusting in neighbours, higher educational level (>9 years), not having someone to consult when you are in trouble, not working, having been socioeconomically disadvantaged in childhood, only greeting or less with neighbours, and not having the experience of dementia care. Having access to a GP, living alone, and going out less than once a week did not show a significant association. CONCLUSIONS: This large-scale study explored factors associated with anticipatory anxiety about the possibility of not receiving proper dementia care should it be needed in the future. Further studies concerning interventions to decrease such anxiety are needed.

OBJECTIVES: The Mini-Mental State Examination (MMSE) is widely used as a cognitive screening test for older adults; however, cognitive performance can be affected by age, education, and sample selection bias, including time and place. The aims of this study were to examine the distribution of scores on the Japanese version of the MMSE in an urban community sample and to provide normative data for older Japanese adults. METHODS: A questionnaire survey was conducted on all residents aged 65 years and older living in an urban district in Tokyo (N = 7682). From among this population, 3000 residents were randomly selected to receive visits from trained nurses and to have their health status checked and their cognitive function examined using the MMSE. RESULTS: Of the 2786 eligible residents, the MMSE was administered to 1341 (47%) and successfully completed by 1319 (mean age, 74.4 ± 6.4 years; mean years of formal education, 12.6 ± 2.9). The median score was 28. A total of 143 residents (10.8%) had scores below the traditional 23/24 cutoff point. Younger age and higher education were associated with better performance. Greater variation was seen among the oldest and least educated residents, especially among women. CONCLUSION: The results of this study confirm that age and education affect MMSE scores. To ensure the effective use of the MMSE, it is recommended to examine scores corresponding to age and education. The normative data presented are expected to be useful for assessing MMSE scores in older individuals both in and out of the clinical setting. Copyright © 2016 John Wiley & Sons, Ltd.

AIM: The aim of this study was to determine whether daytime sleepiness is related to subjective memory impairment among community-dwelling elderly people, after adjustment for psychosocial variables. METHODS: Questionnaires were mailed to all 5199 elderly residents living in one area of Tokyo. The questionnaires collected information about sociodemographic variables, subjective memory impairment, and excessive daytime sleepiness, which was measured by the Japanese version of the Epworth Sleepiness Scale. Information was also collected on sleep hygiene, health-related variables, and psychosocial variables, including perceived social support, social withdrawal, and work status. RESULTS: Of the 4783 questionnaires that were returned (92.0%), 4185 participants were included in the analysis (valid response rate: 80.5%), after the exclusion of questionnaires with missing data. The average score on the Japanese version of the Epworth Sleepiness Scale was 5.0 ± 3.9 for men and 4.5 ± 3.7 for women. The frequency of excessive daytime sleepiness was 8.3% for men, 5.8% for women, and 7.0% in total. Stepwise multivariate logistic regression revealed the odds ratio of excessive daytime sleepiness as a predictor of subjective memory impairment was 6.06 (95% confidence interval; 3.06-12.03). CONCLUSIONS: Elderly people who complain of daytime sleepiness are potential candidates for interventions related to dementia care after careful consideration of other possible causes of sleepiness.
