AbstractBackgroundMany people are unaware of the potential for dementia risk reduction, but state they would appreciate more information on this topic (1). Raising awareness is important as a first step towards behavior change (2). The knowledge that a set of lifestyle behaviors is beneficial for your cognitive health may also provide additional motivation (2).MethodAn online, free e‐learning on the topic of dementia risk reduction for the Dutch adult population will be developed (in co‐creation with Alzheimer Netherlands). It will cover the following topics: physical activity, healthy diet and alcohol consumption, cognitive activity, mental wellbeing including social wellbeing and sleep, cardiovascular health, and tips from lifestyle coaches and end‐users on how to make sustainable lifestyle changes. The content of the e‐learning will be delivered in stages, so that completion of the full course takes approximately seven weeks.ResultThe e‐learning’s effectiveness in terms of knowledge acquisition, evolution in motivation for health behavior and actual health behavior improvements will be assessed with validated questionnaires in a pre‐post study. Participants (minimum N = 300) will complete an online survey before starting the course, immediately thereafter and again three months later. User experiences and engagement with the e‐learning materials will also be evaluated.ConclusionAwareness of the potential for dementia risk reduction is currently lacking in the general population. An e‐learning is a low‐level means that can be used to increase knowledge and awareness, and could further easily be implemented as a stand‐alone tool or as part of current or future dementia risk reduction initiatives.
