Japan-multimodal intervention trial for prevention of dementia(J-MINT)
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.
Open-label multicenter randomized controlled trial
Subjects who aged 65-85 and have age- and education-adjusted cognitive decline determined by using the National Center for Geriatrics and Gerontology Functional Assessment Tool (NCGG-FAT).
Period of intervention
・Change in a composite score of cognitive function from baseline to a 18-month follow-up.
Key secondary outcomes
・Changes in a composite score of cognitive tests from baseline to 6/12-month follow-up.
・Changes in scores of each cognitive test from baseline to 6/12/18-month follow-up.
・Changes in laboratory and urinary markers from baseline to 6/18-month follow-up.
・Changes in ADL scores from baseline to 6/18-month follow-up.
・Changes in the status of frailty from baseline to 6/18-month follow-up.
・Changes in brain images assessed using MRI or CT from baseline to 18-month follow-up.
・Changes in the number of medications.
