Aim The supermarket task, which is included in the Japanese version of the Rapid Dementia Screening Test, requires the quick (1 min) generation of words for things that can be bought in a supermarket. Cluster size and switches are investigated during this task. We investigated how the severity of dementia related to cluster size and switches on the supermarket task in patients with Alzheimer's disease. Methods We administered the Japanese version of the Rapid Dementia Screening Test to 250 patients with very mild to severe Alzheimer's disease and to 49 healthy volunteers. Patients had Mini- Mental State Examination scores from 12 to 26 and Clinical Dementia Rating scale scores from 0.5 to 3. Patients were divided into four groups based on their Clinical Dementia Rating score (0.5, 1, 2, 3). We performed statistical analyses between the four groups and control subjects based on cluster size and switch scores on the supermarket task. Results The score for cluster size and switches deteriorated according to the severity of dementia. Moreover, for subjects with a Clinical Dementia Rating score of 0.5, cluster size was impaired, but switches were intact. Conclusions Our findings indicate that the scores for cluster size and switches on the supermarket task may be useful for detecting the severity of symptoms of dementia in patients with Alzheimer's disease.

Aim: Artificial nutrition, including tube feeding, continues to be given to dementia patients in numerous geriatric facilities in Japan. However, the clinical characteristics of patients receiving artificial nutrition have not been fully investigated. Therefore, we tried to evaluate the clinical features of those patients in this study. Methods: Various clinical characteristics of all inpatients at 18 of 20 psychiatric hospitals in Okayama Prefecture, Japan, with a percutaneous endoscopic gastrostomy tube, nasogastric tube, or total parenteral nutrition were evaluated. Results: Two hundred twenty ‐ one patients (5.4% of all inpatients) had been receiving artificial nutrition for more than 1 month, and 187 (130 women, 57 men; 84.6% of 221 patients) were fully investigated. The mean age was 78.3 years old, and the mean duration of artificial nutrition was 29.8 months. Eighty ‐ four patients (44.7% of 187 patients) were receiving artificial nutrition for more than 2 years. Patients with Alzheimer's disease (n = 78) formed the biggest group, schizophrenia (n = 37) the second, and vascular dementia (n = 26) the third. Conclusion: About one ‐ fifth of the subjects receiving artificial nutrition were in a vegetative state. More than a few patients with mental disorders, including schizophrenia, also received long ‐ term artificial nutrition. We should pay more attention to chronic dysphasia syndrome in mental disorders. [ABSTRACT FROM AUTHOR]

Background: The Japanese government recently announced the ‘Five ‐ Year Plan for Promotion of Measures Against Dementia (Orange Plan)’ to promote people with dementia living in their communities. To achieve this, it is imperative that patients hospitalized with behavioural and psychological symptoms of dementia (BPSD) are helped to return to their own homes. The aim of the present study was to identify predictors of home discharge among patients hospitalized for BPSD. Methods: A single ‐ centre chart review study was conducted on consecutive patients hospitalized from home between April 2006 and March 2011 for the treatment of BPSD. The frequency of discharge back to home was examined in relation to a patient's active behavioural problems and demographics at the time of admission. Diagnoses of dementia were made on the basis of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and consensus guidelines for the clinical and pathologic diagnosis of dementia with Lewy bodies. Results: In all, 391 patients were enrolled in the study. Of these patients, 163 (42%) returned home. Multiple logistic regression analysis identified high Mini ‐ Mental State Examination and Nishimura ‐ style senile activities of daily living scores as significant independent predictors of home discharge. In contrast, living alone and manifestation of aggressiveness at the time of admission were negatively associated with home discharge. Conclusions: Few patients hospitalized for BPSD are discharged home, and this number is affected by a patient's clinical and demographic characteristics at the time of admission. These findings should be considered in designing and implementing optimal management and care strategies for patients with BPSD. [ABSTRACT FROM AUTHOR]

Background Japan is one of the most rapidly ageing societies in the world. A number of municipalities have started services for the prevention of cognitive decline for community-dwelling elderly individuals, but the effectiveness of these services is currently insufficient. Our study explored the efficacy of a comprehensive intervention programme consisting of physical and leisure activities to prevent cognitive decline in community-dwelling elderly subjects. Method We administered a 12-week intervention programme consisting of physical and leisure activities aimed at enhancing participants' motivation to participate and support one another by providing a pleasant atmosphere, empathetic communication, praise, and errorless support. This programme for the prevention of cognitive decline was conducted as a service by the city of Maebashi. All participants underwent the Five- Cog test, which evaluated the cognitive domains of attention, memory, visuospatial function, language, and reasoning. Executive function was evaluated by the Wechsler Digit Symbol Substitution Test and Yamaguchi Kanji- Symbol Substitution Test. Subjective health status, level of social support, functional capacity, subjective quality of life, and depressive symptoms were assessed with a questionnaire. Grip strength test, timed up-and-go test, 5-m maximum walking times test, and functional reach test were performed to evaluate physical function. Fifty-two participants were randomly allocated to intervention ( n = 26) and control ( n = 26) groups. Twenty-six participants, aged between 65-87 years, received intervention once a week at a community centre. The programme was conducted by health-care professionals, with the help of senior citizen volunteers. Results The intervention group ( n = 19) showed significant improvement on the analogy task of the Five- Cog test ( F1,38 = 4.242, P = 0.046) and improved quality of life ( F1,38 = 4.773, P = 0.035) as compared to the control group ( n = 24). Conclusion A community-based 12-week intervention programme that aimed to enhance motivation to participate in activities resulted in improvements in some aspects of cognitive function and quality of life. Senior citizens who volunteered in the present intervention enabled the smooth implementation of the programme and alleviated the burden on professional staff. [ABSTRACT FROM AUTHOR]
