Overview
Japan Prospective Studies Collaboration for Aging and Dementia
Japan Prospective Studies Collaboration for Aging and Dementia (JPSC-AD） study is a collaborative prospective cohort study of approximately 10,000 elderly people from 8 newly-established community-based dementia cohort studies in Japan, in which the data is prospectively collected by using the pre-specified standardized protocol. The purpose of this study is to evaluate quantitatively environmental and genomic risk factors for dementia in Japanese and to establish effective preventive strategies for dementia, in order to realize healthy aging society.
In this study, the definitions of collected data and the diagnostic procedures of dementia have been pre-specified across the cohort studies in 2015 before starting the baseline survey. Approximately 10,000 community-dwelling individuals aged 65 years or older at 8 sites of Japan will be recruited in the baseline survey from 2016 to 2018, and followed up to detect incident cases of dementia for at least 5 years. In the baseline survey, the following data has been collected: lifestyle information (smoking habits, alcohol intakes, diet, physical activity, etc.), medical history, physical examination, blood test, and brain magnetic resonance imaging (MRI). Frozen samples of serum and plasma (-80℃) have been also stored.
This study has been funded by the research and development grants for dementia, Japan Agency for Medical Research and Development (AMED) since 2015.
