Study information
Title
Japan-multimodal intervention trial for prevention of dementia(J-MINT)
Objective
The aims of this study are:
1) to identify whether a multidomain intervention including management of lifestyle-related disease, exercise,
nutritional guidance, and cognitive training can prevent the progression of cognitive decline;
2) to clarify the mechanisms of cognitive risk reduction by using blood biomarkers,
omics analysis, and brain imaging analysis;
3) to conduct research in collaboration with private companies, aiming at the future social implementation of new dementia prevention services.
Study design
Open-label multicenter randomized controlled trial
Subject
