Background 
A growing body of evidence shows that health and lifestyle factors account for up to 40% of all dementia cases worldwide1. Most people, however, seem unaware of the potential of dementia prevention, let alone of specific actions that are required to improve brain health2,3. mHealth tools could potentially increase awareness and motivation to change4. The aim of this study was to investigate a mobile app (MijnBreincoach) on feasibility, increase in knowledge and motivation to change.

Methods 
A pre-post design was used, assessing self-reported data, user tracking and informal focus groups. Participants were community-dwelling, Dutch speaking and in midlife (40-75y), living in the Province of Limburg. During the 3-month intervention period, people used the app to identify room-for-improvement, based on the LIBRA score consisting of 12 modifiable factors5, and chose a lifestyle topic to receive daily notifications. Linear mixed models were used for statistical analyses.

Results 
Of the total study sample (n=299), 190 (63.6%) participants completed the post-evaluation and 167 (55.9%) installed the app. Reasons for dropout were mostly technical problems during installation and use, above motivational issues or lack of time. Women (63.1%) installed the app more often than men did (48.7%; p=0.012). 78.4% of the participants stated that this app provided a positive approach towards brain health and >80% felt better informed about dementia risk reduction. User-tracking showed that the usage of the behavioral change functions was low, resulting in no or only modest effects on motivation to change behavior. Women, younger (<60y) and low-to-middle educated participants evaluated the app most positive.

Conclusion 
Most participants evaluated the app as positive and increased their knowledge on the topic. Usage of the app did not result in changes in attitudes and beliefs related to behavioral change. Results will be used to further develop the MijnBreincoach app. Future (controlled) studies are needed to further explore the role of mHealth in dementia risk reduction.

The School for Mental Health and Neuroscience (MHeNs) strives to advance our understanding of brain-behaviour relationships by using an approach integrating various disciplines in neuro- and behavioural science, medicine, and the life sciences more widely. MHeNs performs high-impact mental health and neuroscience research and educates master's students and PhD researchers. MHeNs performs translational research, meaning practical collaboration between researchers in the lab and in the hospital. MHeNs is one of six graduate schools of the Faculty of Health, Medicine and Life Sciences (FHML) aligned to the Maastricht University Medical Centre+ (MUMC+).
