The effectiveness and safety of yokukansan (TJ-54), a traditional Japanese medicine (kampo) for the treatment of the behavioural and psychological symptoms of dementia (BPSD), were evaluated in 106 patients diagnosed as having Alzheimer's disease (AD) (including mixed-type dementia) or dementia with Lewy bodies. Patients were randomly assigned to group A (TJ-54 treatment in period I and no treatment in period II; each period lasting 4 wk) or group B (no treatment in period I and TJ-54 treatment in period II). BPSD and cognitive functions were evaluated using the Neuropsychiatric Inventory (NPI) and the Mini-Mental State Examination (MMSE), respectively. Activities of daily living (ADL) were evaluated using Instrumental Activities of Daily Living (IADL) in outpatients and the Barthel Index in in-patients. For the safety evaluation, adverse events were investigated. Significant improvements in mean total NPI score associated with TJ-54 treatment were observed in both periods (Wilcoxon test, p=0.040 in period I and p=0.048 in period II). The mean NPI scores significantly improved during TJ-54 treatment in groups A and B (p=0.002 and p=0.007, respectively) but not during periods of no treatment. Among the NPI subscales, significant improvements were observed in delusions, hallucinations, agitation/aggression, depression, anxiety, and irritability/lability. The effects of TJ-54 persisted for 1 month without any psychological withdrawal symptoms in group A. TJ-54 did not show any effect on either cognitive function or ADL. No serious adverse reactions were observed. The present study suggests that TJ-54 is an effective and well-tolerated treatment for patients with BPSD.

Background: The aim of the present paper was to establish a new objective scale to measure vitality related to activities of daily living in elderly patients with dementia. Methods: Cross‐sectional and longitudinal observational studies were carried out on patients and residents in long‐term care facilities. Reliability of the scale was examined by determining test–retest reliability, interrater reliability and internal consistency. Validity of the scale was evaluated with respect to criterion validity and predictive validity. Clinical usefulness of the scale was tested by measuring the time taken to perform scoring and evaluating the changes in the score before and after behavioral therapy for functional urinary incontinence. Results: The test–retest correlation coefficient was 0.98. Mean kappa coefficient of Vitality Index was 0.63. Interrater coefficient of variation was 0.14. Cronbach α of the Index was 0.88. Vitality Index was negatively correlated with Geriatric Depression Scale (GDS) (P < 0.01). A low score was an independent risk factor for survival. Behavioral therapy for functional urinary incontinence increased Activities of Daily Living (ADL) (P < 0.05) and Vitality Index (P < 0.05). Conclusion: Vitality Index could be a new tool to assess patients with dementia.

Aim:We aimed to determine whether plasma sex hormone levels are associated with activities of daily living (ADL), cognition, depression and vitality in elderly individuals with functional decline.g gi_534 282..289Methods: Two hundred and eight consecutive persons 70 years or older (108 men and 100 women; mean 1 standard deviation, 81 1 7 years) with a chronic stable condition, receiving long-term care at a long-term care facilities located in Nagano Prefecture, Japan, were enrolled. Plasma total testosterone, free testosterone (only in men), dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S) and estradiol levels were determined in the morning after an overnight fast. Comprehensive geriatric assessment was performed including basic ADL by Barthel Index, instrumental ADL, cognitive function by Hasegawa Dementia Scale -Revised, mood by Geriatric Depression Scale and ADL-related vitality by Vitality Index.Results: Simple regression analysis showed that, in men, plasma total and free testosterone levels were associated with basic ADL (R = 0.292 and R = 0.282), instrumental ADL (R = 0.261 and R = 0.408), cognitive function (R = 0.393 and R = 0.553) and vitality (R = 0.246 and R = 0.396), while DHEA(-S) was associated with cognitive function, and estradiol with cognitive function as well as vitality. In women, the only significant correlation was between DHEA(-S) and basic ADL. Adjustment for age and nutritional markers did not influence the associations of plasma sex hormone levels with functional scores except for that of free testosterone with Barthel Index. Conclusion:These results suggest that sex hormones have sex-specific associations with physical and neuropsychiatric functions in elderly individuals, and that endogenous testosterone is related to global function in elderly men.

Significant improvement by intervention was shown in multiple domains including cognitive function and BPSD. Cognitive decline and worsening of BPSD are predictors of care burden and hospitalization, thus intensive rehabilitation for dementia was beneficial for both individuals with dementia and their caregivers.

Background Female sex is an important factor predisposing individuals to frailty. Appropriate nutrition is one of the most effective ways to prevent older adults from developing frailty; Sex-related differences have also been detected in the association between nutritional intervention and health-related outcomes. However, few studies have discussed these sex-related differences. The aim of the present study was to investigate the sex-related differences in the association between frailty and dietary consumption. Methods We conducted a cross-sectional study which investigated community-dwelling older adults aged ≥65 years. We surveyed age, sex, body mass index, family arrangement (living alone, living with a partner or living with parent(s) and/or child (ren)), dietary consumption and frailty status. Dietary consumption was surveyed using a food frequency questionnaire that included 13 major food categories (fish, meat, eggs, dairy products, soybean products, vegetables, seaweeds, potatoes, fruits, fats or oils, snacks, salty foods and alcohol). Frailty was defined by the Kihon Checklist score. The Kihon Checklist is composed of 25 simple yes/no questions, and it has been validated as a metric for frailty. A higher score indicates a greater degree of frailty. Multinomial regression analysis was performed to clarify the association between frailty and dietary consumption for each sex. Results We analyzed 905 older adults (420 (46.4%) were male). After adjusting for cofounders, a low frequency of meat consumption (less than twice/week) was associated with a high prevalence of frailty in men (odds ratio: 2.76 (95%CI: 1.12–6.77), p = 0.027). In contrast, in women, low frequencies of consumption of fish, meat, vegetables, potatoes and snacks were associated with a higher prevalence of frailty compared with those who consumed foods from those categories daily (odds ratios: fish 2.45 (1.02–5.89), p = 0.045; meat 4.05 (1.67–9.86), p = 0.002; vegetables 5.03 (2.13–11.92), p < 0.001; potatoes 3.84 (1.63–9.05), p = 0.002; snacks 2.16 (1.02–4.56), p = 0.043). Conclusions More food categories were associated with frailty in women than in men. Nutritional intervention to prevent frailty is presumably more effective for women than for men.
