memory and other cognitive abilities, while inflicting an enormous socioeconomic burden. The complexity of
dementia and its associated comorbidities presents immense challenges for dementia research and care, particularly
in clinical decision-making.
Main body: Despite the lack of disease-modifying therapies, there is an increasing and urgent need to make timely
and accurate clinical decisions in dementia diagnosis and prognosis to allow appropriate care and treatment.
However, the dementia care pathway is currently suboptimal. We propose that through computational approaches,
understanding of dementia aetiology could be improved, and dementia assessments could be more standardised,
objective and efficient. In particular, we suggest that these will involve appropriate data infrastructure, the use of
data-driven computational neurology approaches and the development of practical clinical decision support
systems. We also discuss the technical, structural, economic, political and policy-making challenges that accompany
Conclusion: The data-driven era for dementia research has arrived with the potential to transform the healthcare
system, creating a more efficient, transparent and personalised service for dementia.
