Abstract
AIM In Japan, an additional system for patients with suspected or diagnosed dementia during hospitalization for physical illness began in 2016. We examined the clinical characteristics of older patients with suspected or diagnosed dementia during hospitalization. METHODS The study participants consisted of 569 patients. Current age, sex, comorbidities, causative disease for admission, body mass index (BMI), blood tests, environment before admission, prescription history before admission and rate of delirium were examined. Simple regression analysis for high-frequency diseases was carried out with the respective risk factors as independent variables. Multiple regression analysis was then carried out. RESULTS Infection had the highest frequency in the causative diseases for admission. A total of 48% of patients had delirium during hospitalization. The delirium group had the highest frequency of being at home. In the infection group, BMI and serum albumin were lower in the non-infection group (BMI 19.0 ± 3.7 vs 20.4 ± 4.1; P < 0.001, albumin 2.1 ± 0.7 vs 3.3 ± 0.6 g/dL; P < 0.001 respectively). White blood cell count and C-reactive protein were higher than in the non-infection group, respectively (white blood cell count 11181.4 ± 6533.3 vs 8765.8 ± 111 424.3/μL; P = 0.007, C-reactive protein 8.6 ± 8.6 vs 3.0 ± 5.2 mg/dL; P < 0.001 respectively). Using independent factors associated with infection, multiple regression analysis was performed. BMI (P = 0.013), serum albumin (P < 0.001) and nursing home care before admission (P < 0.001) had significant correlations. CONCLUSIONS Assessment of delirium and the environment before admission of older patients with suspected or diagnosed dementia when hospitalized are necessary. Furthermore, evaluation of nutrition might also contribute to reducing deterioration due to physical illness. Geriatr Gerontol Int 2024; ••: ••-••.

Abstract
INTRODUCTION We examined the efficacy of a multidomain intervention in preventing cognitive decline among Japanese older adults with mild cognitive impairment (MCI). METHODS Participants aged 65-85 years with MCI were randomized into intervention (management of vascular risk factors, exercise, nutritional counseling, and cognitive training) and control groups. The primary outcome was changes in the cognitive composite score over a period of 18 months. RESULTS Of 531 participants, 406 completed the trial. The between-group difference in composite score changes was 0.047 (95% CI: -0.029 to 0.124). Secondary analyses indicated positive impacts of interventions on several secondary health outcomes. The interventions appeared to be particularly effective for individuals with high attendance during exercise sessions and those with the apolipoprotein E ε4 allele and elevated plasma glial fibrillary acidic protein levels. DISCUSSION The multidomain intervention showed no efficacy in preventing cognitive decline. Further research on more efficient strategies and suitable target populations is required. HIGHLIGHTS This trial evaluated the efficacy of multidomain intervention in individuals with MCI. The trial did not show a significant difference in preplanned cognitive outcomes. Interventions had positive effects on a wide range of secondary health outcomes. Those with adequate adherence or high risk of dementia benefited from interventions.

Abstract
Background Because dementia is a long-term condition, the appropriate involvement of health-care professionals is considered important. However, little is known about the factors associated with changes in family caregiver burden. Objective To clarify changes in family caregiver burden and associated factors during follow-up at a memory clinic. Methods A retrospective cohort study was conducted, enrolling 495 pairs of patients with dementia or mild cognitive impairment and their family caregivers. A total of 120 pairs completed the second evaluation. The caregiver burden was assessed using the Zarit Burden Interview (ZBI). Data at the initial visit and after an average follow-up of about 2 years were compared and analyzed. Results At initial visit, the patients' mean age, Mini-Mental State Examination (MMSE) and ZBI scores were 78.6±5.6 years, 23.3±3.5, and 22.6±16.7, respectively. At follow-up, MMSE scores decreased (21.4±4.5, p < 0.001), but ZBI scores remained similar (22.5±13.6). When the difference in ZBI scores between the two time points was defined as ΔZBI, and the related factors were analyzed by multiple regression analysis, ZBI scores at the initial visit, start of psychotropic drug, and decrease of neuropsychiatric symptoms were identified as significant factors (p < 0.001, p = 0.003, p < 0.001, respectively). A significant negative correlation was found between ZBI scores at the initial visit and ΔZBI (r = -0.588, p < 0.001). Conclusions These findings suggest the importance of assessing changes in the burden experienced by family caregivers during the disease follow-up.

Abstract
Objective To evaluate the effectiveness of a dyadic outpatient rehabilitation program focused on improving the real-life daily activities of patients with mild cognitive impairments or dementia and their caregivers. Design Retrospective study. Subjects Eight patients with mild cognitive impairments or dementia and their caregivers. Methods The rehabilitation program comprised eight 1-hour sessions by occupational therapists with patients and his/her caregivers. Patients were assessed for motor function, cognitive function, and quality of life, and their caregivers were assessed for depression and caregiver burden. Participants were assessed at pre-program and post-program, and 3-month follow-up. Results The scores of caregiver-assessed Quality of life in Alzheimer's disease scale in patients significantly improved at post-program (median [interquartile range], 30.0 [7.0]) compared with pre-program (27.0 [2.8], effect size = 0.77, p = 0.029). In caregivers, the Zarit Caregiver Burden Interview scores decreased significantly at post-program (16.5 [13.0]) compared with pre-program (22.0 [17.5], effect size = 0.72, p = 0.042). There were no significant differences in other assessments. Conclusions The rehabilitation program focused on real daily activities and demonstrated to improve patients' quality of life and caregivers' depression and caring burden through patient-caregiver interaction. Future enhanced follow-up systems are warranted.

Abstract
Background As the number of patients with dementia increases, so do the social costs. In recent years, attempts have been made to reduce risk to be dementia and treat it from the early stages of the disease, making it important to estimate the costs of the early stages. Objective To estimate the medical and social costs of the early stages of Alzheimer's disease (AD), which include mild cognitive impairment (MCI) due to AD and mild AD. Methods Questionnaires were used to obtain basic information (e.g., age, cognitive function) and medical costs, social care costs, family caregiver medical costs, and family caregiver informal care costs from patients with MCI due to AD or mild AD who were attending a memory clinic. A comparison was then conducted between these two groups. Results Patients with mild AD had higher total costs, patient medical costs, patient social care costs, and family caregiver informal care costs than did patients with MCI; however, only patient medical costs were significantly different (p = 0.022). A detailed analysis of patient medical costs revealed that anti-dementia drug treatment costs were significantly higher in patients with mild AD (p < 0.001). Conclusion Compared with patients with mild AD, those with MCI may have lower patient and family caregiver costs. As it is important to reduce social costs through risk reduction and therapeutic interventions from the early stages of AD, the present findings could help estimate the social costs and verify the cost-effectiveness of early interventions for AD.

Abstract
This study aims to clarify the dynamics of information provision and human interaction to satisfy the needs of family caregivers. A questionnaire survey consisting of items on information received at and after diagnosis, persons and resources consulted, needs, and caregiver-oriented outcomes was conducted. Among the respondents, 2295 individuals who were caring for people with dementia were divided into quartiles by the time after diagnosis, and differences were statistically analyzed. The time after diagnosis in the first to fourth quartiles was 0.73 ± 0.4, 2.52 ± 0.49, 4.89 ± 0.73, and 10.82 ± 3.7 years, respectively. The number of persons consulted by family caregivers increased significantly from the first to the fourth quartiles (p < 0.001). During this time, attributes of professionals and informal supporters changed depending on the quartile. As time progressed, acceptance of the diagnosis increased, but so did its impact on the lives of family caregivers. These findings revealed differences over time in what family caregivers wanted and the dynamics of interactions that filled their needs. Informal supporters accounted for a significant proportion of the total resources. However, many family caregivers thought the information and support were insufficient. Thus, continuous reform of the care pathway is needed.

Abstract
BACKGROUND Dementia is a disease that is frequently associated with significant caregiving burden. The present study was conducted on patients with dementia in order to investigate the causes of caregiver burden using the Dementia Assessment Sheet for Community-based Integrated Care System-21 items (DASC-21) and Zarit Caregiver Burden Interview (ZBI). METHODS The study subjects consisted of 206 elderly patients (mean age: 80.9 ± 5.9 years) with dementia in an outpatient clinic. Current age, gender, type of dementia, Mini-Mental State Examination, Hasegawa Dementia Scale-Revised, Clinical Dementia Rating (CDR), Geriatric Depression Scale (GDS) and the DASC-21 were investigated. Caregiver burden was assessed by using the ZBI. Behavioural and Psychological Symptom of Dementia (BPSD) were evaluated by using the Neuropsychiatric Inventory (NPI). Simple regression analysis for the ZBI was performed with respective risk factors as independent variables. Thereafter, multiple regression analysis was performed. RESULTS The mean ZBI score was 28.0 ± 18.1, whereas mean DASC-21 score was 44.4 ± 13.2. Simple regression analysis for the ZBI was performed with respective risk factors as independent variables. The DASC-21 (P < 0.001), CDR (P < 0.001), NPI (P < 0.001), and GDS (P = 0.034) were significantly associated with the ZBI. For each item of the DASC-21, Memory (P < 0.001), Orientation (P < 0.001), Solving issues/Common sense (P < 0.001), Instrumental activities of daily living (IADL) outside the home (P < 0.001), IADL inside the home (P < 0.001), Physical ADL① (P < 0.001) and Physical ADL② (P = 0.014) were also significantly associated with the ZBI. To find the independent association of the ZBI, multiple regression analysis was performed. The results showed that DASC-21 (P < 0.001) and NPI (P < 0.001) had significant correlation. For each item of the DASC-21, Memory (P = 0.014) and Solving issues/Common sense (P < 0.001) were also shown to have significant correlation. CONCLUSIONS Both BPSD, cognition and IADL have affected caregiver burden. The DASC-21 is useful for determining the causes of caregiver burden of dementia patients.

Abstract
BACKGROUND Day services (DS) are provided as part of the Japanese public nursing care system. Recent studies have suggested a possible relationship between DS use and limited progression of Alzheimer's disease (AD). This study examined in detail the relationship between improvements in cognitive function and DS use in people with AD. METHODS We retrospectively analysed Revised Hasegawa Dementia Scale (HDS-R) scores of 208 patients with AD at five memory clinics over a 6-month period. The patients were divided into a group that started using DS (n = 132) and a group that did not (n = 76) during the study period. We then compared each participant's total and item scores on the HDS-R between the first clinic visit and 6 months later also compared scores between DS users and non-users. RESULTS DS non-users were younger, predominantly male, had longer school education, and better total HDS-R score at the first visit. After 6 months, DS users showed significantly improved total HDS-R score and individual Serial 7 and Verbal fluency scores. Immediate memory scores were comparable between the first visit and after 6 months. Among the DS users, more frequent participation in DS was significantly associated with improved total HDS-R score. CONCLUSIONS DS use was significantly associated with improved HDS-R scores, especially for the Serial 7 and Verbal fluency tasks, and there was no deterioration in Immediate memory score. These results suggest the usefulness of DS participation as a non-pharmacological therapy.

Abstract
<b><i>Introduction:</i></b> Diabetes mellitus (DM) is a risk factor for Alzheimer’s disease (AD). It has also been pointed out that AD associated with DM may have unique characteristics. However, the characteristics of impairment in daily functioning when associated with DM have not been sufficiently investigated. <b><i>Methods:</i></b> In the present study, we compared the characteristics of 261 patients with AD diagnosed in the outpatient memory clinic of a university hospital, divided into diabetic and nondiabetic groups. The MMSE was used to assess cognitive function, and the Dementia Assessment Sheet for Community-based Integrated Care System 21-items (DASC-21) was used as an observational method to assess cognitive function and activities of daily livings. The two groups were compared. Furthermore, simple and multiple regression analysis was carried out in order to find the independent association of age, sex, education, DM, and HbA1c with the DASC-21 and each individual item of the DASC-21. <b><i>Results:</i></b> Diabetic subjects were as follows: MMSE 18.8 ± 4.0, DASC-21 46.0 ± 13.2, and HbA1c 7.07 ± 1.24%, respectively. On the other hand, nondiabetic subjects were as follows: MMSE 19.0 ± 4.5 and DASC-21 42.1 ± 12.2, respectively. In the diabetic group, total score of DASC-21 was higher (DM vs. nondiabetes mellitus [NDM]: 46.0 ± 13.2 vs. 42.1 ± 12.2; <i>p</i> < 0.05) and solving issues and common sense on the DASC-21 were higher than in the nondiabetic group (NDM) (DM vs. NDM: 8.58 ± 2.71 vs. 7.76 ± 2.66; <i>p</i> < 0.05). Multiple regression analysis showed that the presence of DM was the significant determinant of solving issues and common sense on the DASC-21 (<i>p</i> < 0.05). <b><i>Conclusions:</i></b> In AD patients, DM may be associated with impairment of solving issues and common sense.

Abstract
BACKGROUND Alzheimer's disease (AD) is a common cognitive disease that can progress at an accelerating rate. Even with early diagnosis, the families might not recognize AD progressing unless behavioural and psychological symptoms of dementia (BPSD) develop. In many cases, discrepancies could exist between family-assessed AD stage and diagnosed AD stage. This study explored such discrepancies and potential clinical implications. METHODS Participants were 161 new outpatients with AD or mild cognitive impairment at four memory clinics whose AD stage was diagnosed using the Revised Hasegawa Dementia Scale (HDS-R) and Mini-Mental State Examination (MMSE). We classified patients into four groups according to AD severity. Family members completed the Functional Assessment Staging (FAST) scale during an interview. We then assigned patients to three groups according to discrepancies between family-assessed and diagnosed AD stage. Families also completed the Neuropsychiatric Inventory Questionnaire (NPI-Q), which assesses 12 neuropsychiatric domains, in order to examine the presence of BPSD in relation to AD stage. RESULTS Most families (74%-80%) assessed patients as having milder AD than the diagnosed stage. NPI-Q scores and duration of education significantly affected discrepancies with HDS-R and MMSE scores. The NPI-Q domains of anxiety, apathy/indifference, aberrant motor behaviours, and appetite/eating disturbance significantly affected family-assessed FAST. Families of patients with more years of education assessed the AD stage as more advanced than the diagnosed stage. Surprisingly, living together did not significantly affect the discrepancy. CONCLUSIONS Most families assessed AD as milder than the clinically diagnosed AD stage. In addition, high NPI-Q scores and more years of school education significantly affected the discrepancy. Family-assessed FAST was significantly affected by the NPI-Q domains of anxiety, apathy/indifference, aberrant motor behaviours, and appetite/eating disturbance. These results suggest that obvious BPSD are significant factors for Japanese families to recognize AD progress.

Abstract
INTRODUCTION Amyloid β (Aβ) is a brain protein that causes Alzheimer's disease (AD). This study aimed to verify whether hemadsorption using a hexadecyl-alkylated cellulose bead (HexDC) column removes blood Aβ and brain Aβ accumulation in mild cognitive impairment/mild AD cases with normal kidney function. METHODS Two patients with positive Aβ on brain imaging underwent HexDC hemadsorption weekly for 6 months. RESULTS The Aβ removal efficiency of HexDC was 87-99%. Aβ1-40 /Aβ1-42 influx into the blood in one session was 596/56 ng and 489/48 ng for Case A and Case B, respectively. Although brain Aβ accumulation did not clearly change after six months of hemadsorption, cognitive functions measured by the two tests were maintained or slightly improved. CONCLUSION Blood Aβ removal was performed in two early AD patients with normal kidney function without adverse events, and it slightly improved or maintained cognitive function.

Abstract
Background In this study, we investigated subjective geriatric complaints (SGCs) as conditions regarding health concerns in community-dwelling older people and analyzed their frequencies with aging and relationships with other factors. Methods This cross-sectional study enrolled 10,434 older people living in a community with a representative aging population in Japan. A questionnaire was sent by mail to those who had not applied for formal care needs certification. The presence of and concern for symptoms common in old age were asked as SGCs, as were physical function levels, multimorbidity, and depression. Categorical principal component analysis (CATPCA) of the symptoms was performed, and the association between the obtained components and other factors was analyzed. Results The mean age of the participants was 73.7 ± 6.1 years, and 52.5% were women. On average, they had 1.72 ± 1.57 SGCs, which showed a gradual increase with age. The results of the CATPCA revealed four components: SGC1, excretory/circulatory/swallowing complaints; SGC2, audiovisual complaints; SGC3, neurological complaints; and SGC4, musculoskeletal complaints. All SGC components were independently associated with physical function, multimorbidity, and depression. Conclusions Each SGC showed various frequencies and differences along with aging, and SGCs were classified into four components that were thought to share a common background. These findings could contribute to the planning of better health management strategies for older people.

Abstract
BACKGROUND Dementia cafés have been attracting attention as a new approach to dementia care, but the effects of the participation of medical professionals remain unclear. OBJECTIVE To clarify the significance of collaboration between medical professionals and dementia cafés. METHODS Questionnaires regarding the numbers of staff and guests, whether medical professionals introduced guests, whether cafés announced their activities to medical institutions, and whether people with dementia played a role were sent to dementia cafés throughout Japan. The responding dementia cafés were then divided into two groups according to the presence or involvement of medical professionals and institutions and compared. RESULTS Responses were received from 148 dementia cafés, among which, medical professionals participated in 96 (64.9%). Significantly more people with dementia living at home attended cafés run or staffed with medical professionals (p = 0.021 and p = 0.017, respectively), as well as when medical professionals introduced guests to the café or when the café announced their activities to medical institutions (p = 0.001 and p = 0.002, respectively). Significantly more people with dementia played a role in cafés where medical professionals were administrators or staff (p = 0.008 and p = 0.018, respectively). Similar effects were observed for family caregivers. CONCLUSION The participation and involvement of medical professionals and institutions in dementia cafés increased the attendance of people with dementia, especially those living at home. These results suggest that dementia cafés are an effective hub for connecting care for dementia with medical care, and thus help avoid fragmentation in dementia care.

Abstract
Background/Objectives The Japan-multimodal intervention trial for prevention of dementia (J-MINT) is intended to verify the effectiveness of multi-domain interventions and to clarify the mechanism of cognitive improvement and deterioration by carrying out assessment of dementia-related biomarkers, omics analysis and brain imaging analysis among older adults at high risk of dementia. Moreover, the J-MINT trial collaborates with partnering private enterprises in the implementation of relevant interventional measures. This manuscript describes the study protocol. Design/Setting Eighteen-month, multi-centered, randomized controlled trial. Participants We plan to recruit 500 older adults aged 65–85 years with mild cognitive impairment. Subjects will be centrally randomized into intervention and control groups at a 1:1 allocation ratio using the dynamic allocation method with all subjects stratified by age, sex, and cognition. Intervention The multi-domain intervention program includes: (1) management of vascular risk factors; (2) group-based physical exercise and self-monitoring of physical activity; (3) nutritional counseling; and (4) cognitive training. Health-related information will be provided to the control group every two months. Measurements The primary and secondary outcomes will be assessed at baseline, 6-, 12-, and 18-month follow-up. The primary outcome is the change from baseline to 18 months in a global composite score combining several neuropsychological domains. Secondary outcomes include: cognitive change in each neuropsychological test, incident dementia, changes in blood and dementia-related biomarkers, changes in geriatric assessment including activities of daily living, frailty status and neuroimaging, and number of medications taken. Conclusions This trial that enlist the support of private enterprises will lead to the creation of new services for dementia prevention as well as to verify the effectiveness of multi-domain interventions for dementia prevention.

Abstract
Aim This study aimed to assess whether CogEvo, a computerized cognitive assessment and training tool, could distinguish patients with mild Alzheimer's disease and mild cognitive impairment from cognitively normal older people. Methods This cross‐sectional study enrolled 166 participants with Alzheimer's disease, mild cognitive impairment and cognitively normal older people. In CogEvo, five types of cognitive tasks were carried out, and the z‐scores were used as a composite score. Logistic regression and receiver operating characteristics analyses were then carried out to evaluate the usefulness of CogEvo in distinguishing between the three groups. Results CogEvo and Mini‐Mental State Examination scores showed excellent correlation, and could significantly differentiate between the Alzheimer's disease, mild cognitive impairment and cognitively normal older people groups (Mini‐Mental State Examination 20.4 ± 3.5, 25.5 ± 1.6 and 27.6 ± 2.0, respectively; CogEvo: −1.9 ± 0.9, −0.8 ± 0.8 and 0.0 ± 1.0, respectively; both P < 0.001 by analysis of variance). Logistic regression analysis adjusted for age, sex and years of education significantly differentiated the mild cognitive dysfunction group (mild cognitive impairment plus mild Alzheimer's disease; n = 78) from the cognitively normal group (n = 88) (P < 0.001), whereas receiver operating characteristics analysis showed moderate accuracy (area under the receiver operating characteristic curve 0.830). Conclusions These results suggest that CogEvo, a computerized cognitive assessment tool, is useful for evaluating early‐stage cognitive impairment. Further studies are required to assess its effectiveness as a combination assessment and training tool. Geriatr Gerontol Int 2021; 21: 192–196.

Abstract
The accumulation of amyloid-β protein (Aβ) and tau in the brain is a major pathological change related to Alzheimer's disease. We have continued to develop Extracorporeal Blood Aβ Removal Systems (E-BARS) as a method for enhancing Aβ clearance from the brain. Our previous report revealed that dialyzers effectively remove blood Aβ and evoke large Aβ influxes into the blood, resulting in a decrease in brain Aβ accumulation after initiating hemodialysis, and that patients who underwent hemodialysis had lower brain Aβ accumulation than those who did not. Here, plasma total tau concentrations from 30 patients undergoing hemodialysis were measured using an ultrasensitive immunoassay and compared to those from 11 age-matched controls. Plasma total tau concentrations were higher in patients with renal failure regardless of whether they underwent hemodialysis, suggesting the involvement of the kidneys in tau degradation and excretion. Hemodialyzers effectively removed blood Aβ but not extracorporeal blood tau. The influx of tau into the blood was observed at around the 1 h period during hemodialysis sessions. However, the influx amount of tau was far smaller than that of Aβ. Furthermore, histopathological analysis revealed similar, not significantly less, cerebral cortex phosphorylated tau accumulation between the 17 patients who underwent hemodialysis and the 16 age-matched subjects who did not, although both groups showed sparse accumulation. These findings suggest that hemodialysis may induce both tau and Aβ migration into the blood. However, as a therapeutic strategy for Alzheimer's disease, it may only be effective for removing Aβ from the brain.

Abstract
BACKGROUND The efficacy and safety of glycogen synthase kinase 3 (GSK-3) inhibitors in patients with Alzheimer's disease (AD) is unknown. OBJECTIVE A systematic review and meta-analysis of randomized controlled trials (RCTs) to test GSK-3 inhibitors on AD patients. METHODS We included RCTs of GSK-3 inhibitors in AD patients and subjects with mild cognitive impairment (MCI), using cognitive function scores as a primary measure. RESULTS Five RCTs (three RCTs using lithium and two RCTs using tideglusib) with 568 patients were included. There was no significant difference in cognitive function scores between the GSK-3 inhibitors and placebo groups [standardized mean difference (SMD) = -0.25, p = 0.11, I2 = 55% ]. However, significant heterogeneity remained. A sensitivity analysis revealed that the lithium subgroup was more effective on cognitive function scores than placebo for AD and MCI (lithium subgroup: SMD = -0.41, p = 0.04; tideglusib subgroup: SMD = -0.02, p = 0.89). Moreover, a meta-regression analysis showed that the effect size of GSK-3 inhibitors on cognitive function scores was associated with study duration (coefficient, -0.0116). For safety outcomes, tideglusib was associated with a higher incidence of increased aspartate aminotransferase than placebo. There were no significant differences in other secondary outcomes between treatments. CONCLUSION Our results suggested that GSK-3 inhibitors were ineffective in treating AD and MCI; however, several studies included in the present meta-analysis were small, and future studies using a larger sample size are needed.

Abstract
AIM Day services (DS) are part of the public nursing care system in Japan. The purpose of DS is to help elderly individuals maintain mental and physical functions, eliminate feelings of isolation among homebound users, and reduce the burden of care on family members. However, the relationship between DS and the progression of Alzheimer's disease (AD) remains unclear. METHODS We retrospectively analyzed 161 AD patients based on available Mini-Mental State Examination (MMSE) scores. The patients were divided into two groups: those who started to use DS (n = 106) and those who did not use DS (n = 55). We then compared the groups' MMSE scores between the first memory clinic visit and the 6-month point. RESULTS There were no significant differences between the two groups with regard to sex and the number of family members, but the non-DS group was younger, had more education, and had better MMSE scores at the first visit. At 6 months, we found a significant improvement in the MMSE scores of DS users, reflecting improved cognitive function. In addition, lower MMSE score at the first visit was associated with greater improvement in MMSE score at 6 months. Interestingly, the frequency of DS use had no significant effect on MMSE score. However, after approximately 6 months, DS use significantly improved the cognitive function of AD patients. CONCLUSIONS DS use significantly improved the cognitive function of AD patients. However, most DS users in Japan are older and have severe dementia. Patients who are younger, have more education, or have mild dementia dislike using DS. As a significant difference was found in the MMSE scores between the two groups after 6 months, DS use appears to be a useful non-drug therapy.

Abstract
INTRODUCTION Dementia cafés have recently been attracting attention. The increased involvement of citizen volunteers and the competence of dementia café staff could enhance the potential of dementia cafés. The aim of the present study was to examine enhancement of the competence of citizen volunteers using a new assessment tool. METHODS This cross-sectional analysis included 433 dementia café staff members, including medical and care professionals and citizen volunteers. A 20-item dementia café staff self-assessment (DCSA) instrument was newly developed. After confirmation of the reliability and validity of the instrument, DCSA scores among citizen volunteers were evaluated. RESULTS DCSA showed very good psychometric properties. The mean (±SD) DCSA score was significantly higher for café staff with a medical and care professional background (n = 267) than for citizen volunteers (n = 166) (2.2±0.5 vs. 1.7±0.7, respectively; p < 0.001). The DCSA scores of citizen volunteers became significantly higher with increasing attendance (minimum: n = 24; 1.3±0.7; intermediate: n = 65; 1.6±0.6; and frequent: n = 77; 1.8±0.7; p < 0.01). CONCLUSION Assessment of the competence of dementia café staff using the DCSA revealed the potential of citizen volunteers. This tool could also enhance the potential of dementia cafés.

Abstract
AIM Subjective memory complaints (SMC) have attracted attention in recent years in relation to the early stages of dementia. However, it is not clear whether SMC are related to social and leisure activities. The aim of this study was to evaluate SMC in relation to activities in community-dwelling older adults. METHODS A questionnaire inquiring about SMC and social and leisure activities was sent to 14 850 people aged ≥65 years residing in Toyoake City, as part of the Toyoake Integrated Care Study. After a preliminary analysis, we targeted respondents aged ≥70 years. Therefore, 6685 people were included in the analysis. Three question items were used detecting SMC: the feeling of a memory problem (SMC-1), memory loss pointed out by others (SMC-2) and difficulty in recalling today's date (SMC-3). Logistic regression was carried out to determine the relationship between SMC and activities. RESULTS In response to SMC-1, 2 and 3, 45.3%, 13.3% and 23.5% participants, respectively, agreed with the statement. Social and leisure activities were negatively associated with SMC-2 and SMC-3, after controlling for confounding factors (SMC-2: odds ratio 0.76, 95% confidence interval 0.65-0.89; SMC-3: odds ratio 0.79, 95% confidence interval 0.70-0.90). However, a significant increase in participation in social and leisure activities was associated with a positive response to SMC-1 (SMC-1: odds ratio 1.24, 95% confidence interval 1.12-1.38). Conclusion A relationship was observed between SMC and social and leisure activities in community-dwelling older people, although differences in the impact of SMC were seen depending on the question asked.

Abstract
BACKGROUND The clinical benefit of cholinesterase inhibitors (ChEIs) for mild cognitive impairment (MCI) remains inconclusive. OBJECTIVE We performed a systematic review and meta-analysis of the efficacy/safety of ChEIs on subjects with MCI. METHODS We included randomized controlled trials (RCTs) of ChEIs in subjects with MCI, using cognitive function scores as a primary outcome measure. RESULTS Fourteen RCTs (six using donepezil, four using galantamine, and four using rivastigmine) with 5,278 subjects were included. We found no significant difference in cognitive function scores between the ChEIs and placebo groups [standardized mean difference (SMD) = -0.06, p = 0.38, I2 = 76% ]. However, in the secondary outcomes, ChEIs were associated with a lower incidence of progression to dementia compared with placebo (risk ratio = 0.76, the number needed to treat = 20). For safety outcomes, ChEIs were associated with a lower prevalence of fall than placebo. On the other hand, compared with placebo, ChEIs were associated with a higher incidence of discontinuation due to all causes, discontinuation due to adverse events, at least one adverse event, abnormal dreams, diarrhea, dizziness, headache, insomnia, loose stools, muscle cramps, nausea, vomiting, and weight loss. CONCLUSIONS Although ChEIs have a slight efficacy in the treatment of MCI, there are many safety issues. Therefore, ChEIs are difficult to recommend for MCI. However, the efficacy and safety of ChEIs on MCI with a biomarker-based diagnosis is unclear. Further RCTs are needed to confirm the efficacy and safety of ChEIs when used for individual neuropathological classifications of MCI.

Abstract
INTRODUCTION Multimodal non-pharmacological interventions (MNPIs) have been reported to be effective in improving the cognitive function. Therefore, it is necessary to study these interventions in older people with dementia (PWD) in nursing homes (NHs). AIMS This study aimed to investigate the effects, contents, frequency, duration, length, and form of MNPIs on the global and specific cognitive functions of PWD in NHs through a systematic review, and to consider what kind of intervention design is most effective. METHODS A systematic search of peer-reviewed literature published between January 2008 and October 2018 was performed on the PubMed, Cochrane Library, Web of Science and CINAHL databases. RESULTS Six randomized controlled trials (RCTs) and one non-RCTs were extracted from electronic databases, and a review was carried out. CONCLUSION Our review suggests that MNPIs may improve the global, executive function and memory of PWD in NHs. The combination of exercise, cognitive training and activities of daily living, and intervention at least 3 times a week over at least 8 weeks with, at least 30 min per session using the integrated form is recommended for improving the global and specific cognitive functions of PWD in NHs.

Abstract
OBJECTIVE Although early identification and management services for dementia have become more widespread, their efficacy and the clinical characteristics of service have yet to be fully evaluated. Therefore, the objective of this study is to clarify these issues. MEASUREMENTS The subjects were 164 Japanese users of an early identification and management program for dementia, known as the Initial-phase Intensive Support Team (IPIST), between 2013 and 2015. Nonhierarchical cluster analysis was used to derive subgroups based on cognitive status and ability in activities of daily living (ADL) and behavioral and psychological symptoms of dementia (BPSD). One-way analysis of variance was performed to evaluate differences among the groups derived by the cluster analysis. A paired t test was used to assess how the clinical status of the groups changed between baseline and follow-up. RESULTS Four groups were identified by cluster analysis, i.e. a mild group, a moderate group, a BPSD group with moderate cognitive impairment and severe BPSD, and a severe group with severe cognitive impairment and severe BPSD. Although there were no significant improvements in cognitive impairment or ADL in any group, significant improvements were found in BPSD in the BPSD and severe BPSD groups. Caregiver burden was significantly lessened in all groups. Clinical diagnosis and long-term care insurance service utilization rates were significantly improved overall. CONCLUSION The users of IPIST were classified into four subgroups based on their clinical characteristics. The IPIST program could improve the quality of life of people with dementia and their caregivers.

Abstract
BACKGROUND Early detection and diagnosis is critical in enhancing treatment outcomes for those with cognitive disease. However, most Japanese patients are averse to visiting mental health clinics or taking cognitive screening examinations. A new simple screening test is needed that is acceptable to patients and encourages them to visit a memory clinic if indicated. METHODS We developed a brief screening examination, consisting of four common Japanese old stories, for detection of cognitive disease. A total of 311 patients at three outpatient memory clinics completed the screening test, responding to a 10-question, fill-in-the-blanks assessment. Questions were read aloud to patients with visual impairment, and we transcribed the spoken responses of patients who were physically incapable of writing. The Hasegawa Dementia Scale-Revised (HDS-R) and Mini-Mental State Examination (MMSE) were administered at the same time. RESULTS Using the developed Japanese Old Stories Cognitive Scale (JOSS), we found significant differences between dementia and control or mild cognitive impairment (MCI) groups. The JOSS was less affected by education level than the HDS-R or MMSE, possibly because Japanese old stories are usually learned from family members during preschool years. The JOSS may be able to detect remote memory disturbance in addition to other cognitive dysfunctions. CONCLUSIONS Most patients with AD, even in advanced stages, are averse to visiting a memory clinic because it can be difficult to accept any resulting diagnosis of cognitive disease. JOSS is a quick and simple screening tool to gather evidence of cognitive dysfunction and prompt a referral to a memory clinic. Patients with cognitive disease found the JOSS acceptable, and its high specificity could be useful in encouraging patients to visit already-crowded memory clinics for formal diagnosis and intervention.

Abstract
AIM Hippocampal atrophy shown on magnetic resonance imaging can differentiate Alzheimer's disease (AD) patients from subjects with normal cognition (NC). Simplified automated methods that use volumetric analysis, such as as the voxel-based specific regional analysis system for AD, have become widely used in Japan. However, the diagnostic value of the voxel-based specific regional analysis system compared with visual rating scores for clinical diagnosis is unclear. METHODS Study participants consisted of 37 AD patients, 29 mild cognitive impairment (MCI) patients, and 21 NC subjects. All participants underwent neuropsychological testing and magnetic resonance imaging. The imaging was scored visually for regional brain atrophy by two raters based on a newly developed visual rating score. The voxel-based specific regional analysis system for AD scores were calculated with the analysis system's advanced software. We analyzed whether these scores aid in discriminating among AD, MCI, and NC. RESULTS The AD group had significantly different visual rating scores, regional analysis scores, and all neuropsychological test scores than the NC group. The AD group had significantly different visual rating scores than the MCI group, and a significant difference was observed between the MCI and NC groups on regional analysis scores. Both the visual rating and regional analysis scores showed equivalent correlations with the neuropsychological test scores. CONCLUSIONS Both the visual rating and regional analysis scores are clinically useful tools for differentiating among AD, MCI, and NC.

Abstract
BACKGROUND/AIMS Dementia cafés are becoming widespread as a new approach to dementia care, but their operational procedures and significance have not been adequately studied. METHODS On-the-job training (OJT) for professionals planning to operate a dementia café in the future was conducted in a pioneering dementia café in Japan. The reports of OJT trainees' observations and learning were analyzed qualitatively. RESULTS Reports could be summarized in up to 9 themes: 2 related to the atmosphere and significance of the café, 3 related to the guests, such as people with dementia and their families, and 4 related to the café staff. DISCUSSION The results of the present study identified the elements that make up dementia cafés and their significance and suggest that dementia cafés could be a new type of community resource for dementia care in the future.

Abstract
The accumulation of amyloid-β protein (Aβ) in the brain signifies a major pathological change of Alzheimer's disease (AD). Extracorporeal blood Aβ removal system (E-BARS) has been under development as a tool for enhancing the clearance of Aβ from the brain. Previously, we revealed that dialyzers remove blood Aβs effectively, evoking substantial Aβ influx into the blood during hemodialysis sessions as one form of blood Aβ removal by E-BARS, and that postmortem brains of hemodialysis patients exhibited lower Aβ accumulation. Here, we present a case report of a 77-year-old male patient with end-stage renal failure whose Aβ accumulation in the brain declined by initiating and continuing hemodialysis for 6 months. This report suggests that blood Aβ removal by E-BARS could be an effective therapeutic method for AD.

Abstract
Background Neuropsychological tests that can track changes in cognitive functions after diagnosis of Alzheimer disease (AD) and mild cognitive impairment (MCI), including episodic memory, should be further developed. Methods The participants of our study consisted of 22 mild AD patients and 11 MCI patients. They were followed up for 2 years. Brief cognitive screening tests were administered to the participants. Longitudinal changes in test performance were evaluated and analyzed. Results In this longitudinal study, the Scenery Picture Memory Test (SPMT) showed significant changes over 2 years in both MCI and AD participants. The Mini-Mental State Examination (MMSE) and Word Fluency Test-vegetable showed significant changes only in AD participants. Other tests all showed little or no decline in results. Conclusions The SPMT can be a useful tool for effectively observing changes during follow-up of MCI and AD patients.

Abstract
Patients with chronic renal failure often have hypertension, but the cause of hypertension, other than an excess of body fluid, is not well known. We hypothesized that the bulbospinal neurons in the rostral ventrolateral medulla (RVLM) are stimulated by uremic toxins in patients with chronic renal failure. To investigate whether RVLM neurons are sensitive to uremic toxins, such as uric acid, indoxyl sulfate, or methylguanidine, we examined changes in the membrane potentials (MPs) of bulbospinal RVLM neurons of Wister rats using the whole-cell patch-clamp technique during superfusion with these toxins. A brainstem-spinal cord preparation that preserved the sympathetic nervous system was used for the experiments. During uric acid, indoxyl sulfate, or methylguanidine superfusion, almost all the RVLM neurons were depolarized. To examine the transporters for these toxins on RVLM neurons, histological examinations were performed. The uric acid-, indoxyl sulfate-, and methylguanidine-depolarized RVLM neurons showed the presence of urate transporter 1 (URAT 1), organic anion transporter (OAT)1 or OAT3, and organic cation transporter (OCT)3, respectively. Furthermore, the toxin-induced activities of the RVLM neurons were suppressed by the addition of an anti-oxidation drug (VAS2870, an NAD(P)H oxidase inhibitor), and a histological examination revealed the presence of NAD(P)H oxidase (nox)2 and nox4 in these RVLM neurons. The present results show that uric acid, indoxyl sulfate, and methylguanidine directly stimulate bulbospinal RVLM neurons via specific transporters on these neurons and by producing oxidative stress. These uremic toxins may cause hypertension by activating RVLM neurons.

Abstract
BACKGROUND/AIMS Dementia is a priority issue in the public health realm. However, few reports address problems of dementia in the real world or provide comprehensive road maps to solve these problems. METHODS Nine groups of questions covering 4 topics were discussed using the Delphi method, relating to (1) current achievements and challenges regarding inclusive and holistic care in the community, (2) patients who are at a high risk of being excluded from care, (3) suggestions for a road map for the establishment of better and more inclusive medical and social care, and (4) unmet needs of patients with dementia. RESULTS In total, 477 opinions were obtained. Family issues, psychological/behavioral symptoms, and complications secondary to physical disorders are main factors for being excluded from care. To create a road map for care we have to address the topics of reaffirming care principles, multidisciplinary coalitions, and education for stakeholders. CONCLUSION Further effective collaboration to promote dementia care is required.

Abstract
In this paper, we propose a new interview method of eliciting needs for support completely and accurately from people with early-stage dementia for identifying their real needs, with the eventual objective of designing effective Assistive Technology. The interview procedure consists of the following steps: (1) entirely identifying tasks of a subject’s everyday living, leisure and social activities (referred to, in all, as “social living activities”), (2) evaluating the subject’s confusion levels (SCLs) about identified tasks based on the subject’s self-rating, together with the caregiver’s rating as a reference, and confusion level discrepancies (CLDs) are found, and (3) predicting the subject’s support requirement levels (SRLs) about confusing tasks based on confusion levels followed by the subject’s revision to thereby find SRL discrepancies (SRLDs). Subjects are asked to reconfirm SRL ratings associated with tasks having SRLDs and/or encouraged to raise the ratings of tasks having CLDs to accurately identify the subject’s SRLs. Six subject-caregiver dyads were interviewed and 22 support needs, including 10 needs that were extracted by reconfirmation or encouragement, were elicited from four subjects. These elicited needs covered the entire social living scene from domestic affairs to social activities, showing that the proposed method was effective in systematically eliciting support needs from people with early-stage dementia. No support needs were elicited, however, from subjects with very little awareness of memory impairment, demonstrating one limitation of the proposed method.

Abstract
AIM Falls are common in patients with cognitive disorder. The purpose of this study was to determine whether global brain atrophy is associated with cognitive function, physical performance and fall incidents in older adults with mild cognitive disorder. METHODS A total of 31 older adults with mild cognitive disorders (mean age 78.9 ± 7.3 years) were studied, and 10 of them had experienced falls and the others had not in the past 1 year. Cognitive function and physical performance were measured in these patients. Global brain atrophy was determined by the Voxel-Based Specific Regional Analysis System for Alzheimer's Disease software. RESULTS Fallers showed significantly worse scores than the non-fallers in the Global Brain Atrophy Index, Clock Drawing Test (CDT), Verbal Fluency Test (animal), maximum walking time and Timed Up & Go (TUG) Test. The Global Brain Atrophy Index was correlated with the Verbal Fluency Test (animal; r = -0.522), the Verbal Fluency Test with letter (ka; r = -0.337), CDT (r = -0.547), TUG (r = 0.276) and Five Chair Stands Test (r = 0.303) by age-adjusted correlation analyses. Stepwise regression analysis showed that the Global Brain Atrophy Index (β = 1.265, 95% CI 1.022-1.567) was a significant and independent determinant of falls (R(2) = 0.356, P = 0.003). CONCLUSION Global brain atrophy might be indicated as one of the risk factors for falls in older adults with mild cognitive disorders.

Abstract
Extracellular accumulation of amyloid beta (Aβ) is a hallmark of Alzheimer's disease (AD). It has been reported that extracellular perfusion of Aβ inhibits long-term potentiation (LTP), which is strongly related to memory in animal models. However, it has recently been proposed that intracellular Aβ may be the first pathological change to occur in AD. Here, we have investigated the effect on LTP of intracellular injection of Aβ (Aβ(1-40), Aβ(1-42)) into hippocampal pyramidal cells using patch-clamp technique. We found that injection of 1 nM Aβ(1-42) completely blocked LTP, and extracellular perfusion of a p38 MAPK inhibitor or a metabotropic glutamate receptor blocker reversed these blocking effects on LTP. Furthermore, we have examined the effects of different concentrations of Aβ(1-40) and Aβ(1-42) on LTP and showed that Aβ(1-40) required a 1,000-fold higher concentration to attenuate LTP than 1 nM Aβ(1-42). These results indicate that LTP is impaired by Aβ injected into genetically wild-type neurons in the sliced hippocampus, suggesting an acute action of intracellular Aβ on the intracellular LTP-inducing machinery.

Abstract
AIM To delineate relationships among cognitive function, frailty and level of care required in the Japanese long-term care insurance program (LTCIP) in outpatient memory clinic patients. METHODS This was a cross-sectional study carried out at an outpatient memory clinic. Participants were 201 cognitively impaired patients. Cognitive function was measured by the Mini-Mental State Examination (MMSE). Frailty was measured by Timed Up & Go (TUG) and grip strength. Waist circumference, body mass index, living arrangement and level of care required in the LTCIP (rank 1 minor disability to rank 7 severe disability) were also assessed. RESULTS Mean age, MMSE score, TUG score and grip strength were 78.8 ± 6.9 years, 19.6 ± 6.1, 14.6 ± 6.7 s and 16.9 ± 7.5 kg, respectively. A total of 70 patients (34.8%) had not applied for the certification, at least in part because of their younger age and existence of family caregivers. LTCIP rank was correlated both with MMSE score (β: -0.49, P = 0.001), grip strength (β: -0.27, P = 0.005) and living alone (β: -0.18, P = 0.03), but not with TUG score (β: 0.14, P = 0.105). CONCLUSION In outpatients of a memory clinic, care ranks, which define the upper limit of monthly benefit in the Japanese LTCIP, were influenced by age, cognitive function, frailty and living arrangements. Understanding the relationship among these parameters would be useful in predicting the needs of cognitively impaired patients and important when comparing the possible services provided by long-term care systems for them worldwide.

Abstract
BACKGROUND/AIMS Oligomeric amyloid β (Aβ) is currently considered to induce Alzheimer's disease (AD). We examined 2 patients with familial AD who possessed the Osaka (E693Δ) mutation in amyloid precursor protein. To the best of our knowledge, these patients are the first AD cases presumably affected with Aβ oligomers in the absence of senile plaques, and they support the Aβ oligomer hypothesis. METHODS We evaluated the clinical course, neuropsychological data, cerebrospinal fluid biomarker levels, magnetic resonance imaging (MRI) scans, fluorodeoxyglucose-positron emission tomography (PET) scans, and Pittsburgh compound B (PiB)-PET images of these patients. RESULTS In the early stages, these patients developed memory disturbances in a similar rate to patients with sporadic AD. Despite their memory disturbances, both patients showed only limited brain atrophy on MRI and little amyloid accumulation on PiB-PET. Subsequent to the development of memory disturbances, both patients suffered from motor dysfunction, probably due to cerebellar ataxia, and, within a few years, the patients fell into an apallic state. CONCLUSIONS Familial AD patients with Osaka (E693Δ) mutation show severe dementia, cerebellar ataxia, and gait disturbances.
