摘要：

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 5.877.7% 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 20112012.
