Delayed help-seeking for cognitive concerns remains a significant barrier to timely diagnosis and intervention in dementia care. Despite growing emphasis on brain health awareness and risk reduction, many individuals do not seek professional advice when memory concerns emerge. Digital tools offer scalable, accessible approaches to increase awareness, prompt self-reflection, and support earlier engagement with healthcare services when concerns are identified. BrainTrack is a multi-award-winning mobile application designed to provide personalised cognitive insights, educate users about brain health, and encourage timely help-seeking. We will present an integrated, multidisciplinary MRFF-funded program of research examining the development, implementation, and impact of BrainTrack. Presenters will explore how digital tools can enhance brain health awareness, influence help-seeking intentions and behaviours, and support early intervention pathways. The session also considers the role of general practitioners and evaluates the economic and social value of digital health approaches. The symposium features four presentations: (1) co-design and implementation of BrainTrack; (2) user engagement and longitudinal outcomes from survey and app data; (3) general practitioner perspectives on the use of BrainTrack in clinical practice; and (4) a social return on investment evaluation. Together, these presentations provide a comprehensive case study of the design, delivery and impact of a digital public health intervention. Attendees will gain insight into digital approaches to brain health promotion, help-seeking behaviour, and integration into primary care, as well as economic and policy considerations. This symposium will be of interest to researchers, clinicians, and policymakers seeking to adopt, evaluate and/or optimise digital resources and promote early intervention.
