[Japan Prospective Studies Collaboration for Aging and Dementia (JPSC-AD)].

Dementia has become a priority worldwide in terms of both public health and social care due to its rapidly increasing burden in communities. Therefore, the early identification of possible risk factors and the establishment of preventive and treatment strategies for dementia have become increasingly important. The Japan Prospective Studies Collaboration for Aging and Dementia (JPSC-AD) is a collaborative prospective cohort study of approximately 10,000 elderly people from 8 newly established community-based dementia cohort studies in Japan. In this study, the data are prospectively collected using a pre-specified standardized protocol. The purpose of this study is to quantitatively evaluate the environmental and genomic risk factors for dementia in Japan and to establish effective preventive strategies to promote a healthy aging society.
