Systematic Multi-domain Alzheimer's Risk Reduction Trial

Interventionists will follow a standard protocol for delivering the SMARRT intervention that allows for personalization of the specific risk reduction action plan; these plans will evolve over time according to participant progress, motivation and preferences or newly identified risk factors. Staff will use a tracking database to record information for each participant, including session dates, identified risk factors, motivational barriers and important values, and the outcome of discussions around developing goals. For each participant, the exact number and mode (phone or in-person) of contacts will differ, but we will aim to have at least 1 contact per month with each participant. Best practice will include in-person meetings twice a year during the 2-year intervention period.

Participants randomized to the Health Education (HE) group will receive mailed materials (typically 1-2 pages) every 3 months. This will include general information on Alzheimer's and dementia risk reduction using materials from sources such as the Alzheimer's Association and educational materials commonly provided as part of routine care at Kaiser Permanente Washington (KPWA).
