Arms of the Study
Arm 1
Experimental
neuroimaging amyloid diagnosis by MRI and PET scan
There is only one arm. The procedure consists in neuroimaging to diagnose the presence of amyloid plaques in the brains and permit earlier detection of Alzheimer's disease. MRI and PET Scan. Visits at baseline, 1 and 2 years for a full neuropsychological, functional and physical evaluation. At 6 and 18 months in consultation by a Geriatrician and research assistant for a medical check. one PET-Scan in the 2 months following inclusion for amyloid measurements and one MRI, depending on the clinical relevance A blood sample for biobank at visit 2 and at visit 5. Extension study (CogFrail-Plus): additional 2 years follow-up of the COGFRAIL study participants, following the initial 2 years period of the study: 2 Visits at at 36 and 48 months for a full neuropsychological, functional and physical evaluation At 30 and 42 months in consultation by a Geriatrician and research assistant for a medical check A blood sample at 36 and 48 months.
