Rice farming care as a novel method of green care farm in East Asian context: an implementation research.

BACKGROUND: Green care farms, which offer care for people with dementia in a farm setting, have been emerging in the Netherlands. The aim of this study was to 1) implement green care farms which use rice farming in Japan, 2) explore the positive experiences of rice farming care, and 3) compare the effect of rice farming care to that of usual care on well-being and cognitive ability. METHODS: We developed a new method of green care farm in Japan which uses rice farming, a farming that is practiced all over East Asia. The participants were 15 people with dementia (mean age = 75.6 ± 9.8 years) who participated in a one-hour rice farming care program once a week for 25 weeks. We also collected qualitative data on the positive experiences of study participants after the program. As a reference data, we also collected the corresponding data of the usual care group which included 14 people with dementia (mean age = 79.9 ± 5.8 years) who were attending the near-by day-care. RESULTS: The mean participation rate on the rice farming care group was 72.1%. After the intervention, participants reported experiencing enjoyment and connection during the program. It also changed the staff's view on dementia. The green care farm group showed a significant improvement in well-being but no significant difference in cognitive function compared to the usual care group. CONCLUSIONS: Green care farms by using rice farming is promising care method which is evidence-based, empowerment-oriented, strengths-based, community-based dementia service, which also delivers meaningful experience for the people with dementia in East Asia.

[The development of care farming for elderly people with cognitive impairment to enhance social inclusion: A feasibility study of rice-farming care for elderly people with cognitive impairment].

AIM: The aim of this study was to assess the feasibility of rice-farming care among elderly people with cognitive impairment as a tool for social inclusion. METHODS: Eight elderly individuals with cognitive impairment (7 men, 1 woman, mean age 68.3 years old) participated in the program over 25 weeks. The cognitive function, well-being, and depression were assessed before and after the program period. The degree of participants' independence during the program was also assessed. Semi-structured interviews with the participants and caregivers were held after the program period. RESULTS: The average participation rate was 93.0%. There were no unexpected events, and the subjects carried out farmwork almost independently. Regarding their well-being, two participants who scored below the cut-off criterion of mental health before the study scored above the cut-off after the study. Regarding depression, two participants who scored positive with a two-question case-finding instrument no longer scored positive after the study. Interviews with the participants showed that they enjoyed the program, especially because they had peers, a role, and gained positive emotions. Interviews with the caregivers showed that they had recognized for the first time what people can do with their skills. CONCLUSION: The results of the present study indicate that rice-farming was a feasible method of care with a positive impact on the well-being and depression of elderly people with cognitive impairment and enhanced their social participation, drawing out their individual strengths.

Multicentre population-based dementia prevalence survey in Japan: a preliminary report.

Community-based surveys were performed in seven rural areas in Japan to investigate the prevalence of dementia and illnesses causing dementia. A total of 5431 elderly subjects were selected based on census data from 1 October 2009. In total, 3394 participants were examined (participation rate: 62.5%), and 768 dementia cases and 529 mild cognitive impairment cases were identified. Of the illnesses causing dementia, Alzheimer's disease was the most frequent (67.4%), followed by vascular dementia (18.9%), dementia with Lewy body disease (4.6%), mixed dementia (4.2%) and other illnesses. The prevalence of dementia according to 5-year age strata between 65 and 99 years was 5.8-77.7% among the participants. The prevalence of dementia in this study was higher than in previous reports in Japan and other countries. To verify the upward trend of dementia prevalence and its background factors, we have scheduled surveys for three other urban areas in 2011-2012.

Aberrant interference of auditory negative words on attention in patients with schizophrenia.

Previous research suggests that deficits in attention-emotion interaction are implicated in schizophrenia symptoms. Although disruption in auditory processing is crucial in the pathophysiology of schizophrenia, deficits in interaction between emotional processing of auditorily presented language stimuli and auditory attention have not yet been clarified. To address this issue, the current study used a dichotic listening task to examine 22 patients with schizophrenia and 24 age-, sex-, parental socioeconomic background-, handedness-, dexterous ear-, and intelligence quotient-matched healthy controls. The participants completed a word recognition task on the attended side in which a word with emotionally valenced content (negative/positive/neutral) was presented to one ear and a different neutral word was presented to the other ear. Participants selectively attended to either ear. In the control subjects, presentation of negative but not positive word stimuli provoked a significantly prolonged reaction time compared with presentation of neutral word stimuli. This interference effect for negative words existed whether or not subjects directed attention to the negative words. This interference effect was significantly smaller in the patients with schizophrenia than in the healthy controls. Furthermore, the smaller interference effect was significantly correlated with severe positive symptoms and delusional behavior in the patients with schizophrenia. The present findings suggest that aberrant interaction between semantic processing of negative emotional content and auditory attention plays a role in production of positive symptoms in schizophrenia.
