    Objective: To develop and validate the Testamentary Capacity Assessment Screening Tool (TCAST) for older adults, addressing the absence of standardised instruments for testamentary capacity (TC) assessment in Japan. Methods: The TCAST was developed through an iterative process including literature review, interdisciplinary expert consultation, and user testing with older adults. It comprises three subtests: (1) Hypothetical will-making Scenario, (2) Basic financial concepts, and (3) Legal vocabulary. Internal consistency, test–retest reliability, and construct validity were examined using Cronbach's α, intraclass correlation coefficients (ICC), and correlations with the Hasegawa Dementia Scale-Revised (HDS-R), the Executive Interview (EXIT25), and the Geriatric Depression Scale (GDS-15). Group comparisons and receiver operating characteristic (ROC) analyses were conducted to evaluate discriminatory performance. Results: A total of 118 participants—68 cognitively healthy older adults and 50 with dementia—completed the TCAST. Internal consistency was good for Parts 1 and 2 (α = 0.88, 0.70) and lower for Part 3 (α = 0.58). Test–retest reliability was excellent for Parts 1 and 2 (ICC = 0.87, 0.89) and moderate for Part 3 (ICC = 0.58). Construct validity was supported by moderate to strong correlations with HDS-R and EXIT25, but not with GDS-15. All subtests correlated negatively with age and positively with education, and significantly differentiated healthy and dementia groups (p < 0.001). ROC analyses showed strong discriminatory capacity (AUC = 0.86, 0.97, and 0.79 for Parts 1–3). Conclusions: The TCAST is a reliable and valid screening tool for assessing TC in older Japanese adults. It is not designed to categorically determine incapacity, but to highlight domains relevant to testamentary reasoning and support person-centered evaluations. The tool may aid clinicians and legal professionals in identifying both retained abilities and areas needing support, underscoring its potential utility in interdisciplinary approaches to capacity assessment in aging societies.

    Aim: Telepsychiatry is increasingly integral to psychiatric practice. However, few reviews have examined the concordance between assessments conducted in telepsychiatric and face-to-face settings. This systematic review and meta-analysis evaluated the agreement between telepsychiatric and face-to-face settings in the diagnosis and symptom assessment of various psychiatric disorders. Methods: A literature search was conducted using MEDLINE/PubMed, Cochrane Library, Scopus, EMBASE, CINAHL, and PsycINFO. Studies evaluating the concordance between telepsychiatric and face-to-face settings in the diagnosis and symptom assessment of various psychiatric disorders were included and analyzed. Results: Of the 6875 studies in the initial search, 22 studies that met the inclusion criteria were included in the analyses. The diagnostic concordance for 16 psychiatric disorders was “almost perfect” between the two settings (N = 16, n = 848, Cohen's κ = 0.824, confidence interval [CI] = 0.466 to 0.950, P < 0.001). Additionally, the concordance for the symptom rating scales between the two settings ranged from “substantial” in the Brief Psychiatric Rating Scale (N = 1, n = 533, Cohen's κ = 0.789, CI = 0.699 to 0.855, P < 0.001) to “almost perfect” in the Autism Diagnostic Observation Schedule (N = 1, n = 92, intraclass correlation coefficients = 0.943, CI = 0.798 to 0.985, P < 0.001). Conclusions: Telepsychiatry is highly concordant with face-to-face settings regarding psychiatric diagnoses and symptom assessment. In contrast, the present results also suggest that the suitability of telepsychiatry varies across disease types, specific symptoms, and assessment modalities. Although the present results must be interpreted with caution owing to the small number of studies for each assessment and disease, our findings suggest that telepsychiatry may have greater utility in psychiatric diagnostic assessment settings.

    INTRODUCTION: Clinical features of cognitive performance in extreme old age differ from those of pathological cognitive decline in Alzheimer's disease (AD). METHODS: We compared cognitive traits between 638 centenarians aged 100–115 years and 208 and 221 patients with AD from independent facilities. RESULTS: The presence of the apolipoprotein E (APOE) ε4 allele did not affect Mini-Mental State Examination (MMSE) scores in centenarians. Centenarians retained the ability to follow three consecutive commands, associated with their educational background and activities of daily living. Cognitive retention remained unchanged in semi-supercentenarians (aged ≥ 105 years) and supercentenarians (aged ≥110 years). A quantitative genome-wide association study (GWAS) identified two loci associated with maintaining the ability to follow three consecutive commands. DISCUSSION: This is the first study to compare cognitive traits between >600 centenarians and patients with AD. Centenarians attained higher MMSE scores for the phenotype of following three consecutive commands than patients with AD, being useful in clinical practice. Highlights: Cognitive phenotypes in centenarians differ from those in the AD groups Clinical trait to follow consecutive instructions is retained in centenarians but not in AD groups GWAS identified SNPs related to the maintained trait of MMSE in centenarians.

    　概要を見る

    Objectives: Treatment decisions for severe aortic stenosis (AS) are complex, since there are two active and comparable options: transcatheter aortic valve implantation and surgical aortic valve replacement. The disease predominantly affects older individuals, who are frequently comorbid with from cognitive impairment. This study aimed to establish a screening-triggered system to assess the decision-making capacity of patients with AS, support their decision-making, and facilitate referrals to specialists when necessary. Methods: This is a retrospective pre-post observational study. Relevant healthcare professionals were trained to assess and support patients' decision-making capacities. Results: Subtotals of 203 and 244 patients were enrolled before and after the implementation of the system, respectively. The requests for decision-making support significantly increased (from 1.5 % to 14.8 % of the patients). 11.5 % of the patients were identified as with declined decision-making capacity. The proportion of patients who received active treatments for AS significantly decreased from 95.0 % to 83.0 %. The nurses' documentation of patients' decision-making capacities significantly increased. Conclusion: This screening-triggered system identified a substantial proportion of patients with declined decision-making capacity. A significant decrease in patients receiving active treatments for AS and increased documentation of patients' decision-making capacities in nursing records were observed. A future randomized controlled is warranted.

    Objective: To clarify the relationship between life satisfaction and the psychological characteristics of the oldest-old, and explore the factors for achieving mental health and longevity. Design: This cross-sectional study conducted questionnaire surveys and face-to-face interviews as part of a larger prospective cohort study. Setting: Arakawa Ward, a district in Tokyo, Japan. Participants: A total of 247 oldest-old individuals from two age groups, 85+ (aged 85–87 years) and 95+ (aged 95 years or older). Measurements: Life satisfaction was assessed using the Satisfaction with Life Scale (SWLS), developmental stages of the elderly (Erikson's 8th and 9th stages, i.e., ego integrity, and gerotranscendence), and the Big Five personality traits (extraversion, agreeableness, openness, conscientiousness, and neuroticism) using the NEO-Five Factor Inventory. Multiple regression analyses were performed to examine the relationship between the SWLS scores and each assessment, controlling for age, sex, education, activities of daily living, depressive symptoms, and cognitive function. Results: The SWLS scores of 85+ were positively correlated with scores of ego integrity, extraversion, and conscientiousness. Contrastingly, the SWLS scores of 95+ were positively correlated with gerotranscendence scores. Conclusions: Psychological characteristics associated with the level of life satisfaction among community-dwelling oldest-old individuals were identified, but a causal relationship between these factors and life satisfaction was not established. Ego integrity, extraversion, conscientiousness, and gerotranscendence may be associated with enhanced life satisfaction and mental health in the oldest-old. Further, the factors associated with life satisfaction in the 85+ and 95+ age groups varied, suggesting that life satisfaction among the oldest-old has different foundations in different age groups.
