Tailored, Multidomain, and Coach-assisted Digital Program for the Adoption and Maintenance of a Healthy Lifestyle in Middle-aged and Older Adults With Modifiable Risk Factors for Dementia: An Efficacy Study
Alzheimer's Disease (AD) and other Dementias have far-reaching consequences on the lives of sufferers and their loved ones, not to mention the impact on the healthcare system. Several studies have identified protective lifestyle habits that might help reduce the risk of cognitive decline: cognitive engagement, physical activity, and a healthy diet. Our aim is to determine the efficacy of the Luci program, an online, coach-assisted, multidomain, behavioural intervention designed to help middle-aged to older adults reduce their risk of dementia by improving their lifestyle habits. In this study, we hope to demonstrate that participating in the Luci program helps to improve lifestyle habits and that the program could therefore become an effective health promotion tool.
