Primary outcome is feasibility of the multimodal intervention. Secondary outcomes include adherence to intervention components (intervention arms), and adherence to healthy lifestyle changes (all arms). Detailed cognitive assessments (Neuropsychological Test Battery, NTB) and functional assessments (Clinical Dementia Rating, CDR; and Alzheimer's Disease Cooperative Study-Activities of Daily Living, ADCS-ADL) will also be conducted at baseline and 6-month visit for the purpose of obtaining reliable estimates of change over time for power calculations for a future larger multimodal intervention trial (MIND-ADmaxi).
