Predicting Dementia Risk: Progress, Pitfalls, And Priorities, Patricia Nistor, Osvaldo Espin-Garcia, Zul Merali, Shehzad Ali

Brain and Mind Institute

As populations age, identifying individuals at high risk for dementia has become a cornerstone of prevention-oriented public health policy. Accurate and scalable risk stratification could enable early intervention and resource targeting. However, existing models face methodological limitations, including constraints in available data and follow-up duration, challenges in dementia ascertainment, heterogeneity in modelling approaches, and limited external validation. This commentary discusses these challenges and identifies methodological priorities for developing dementia risk algorithms that are robust and suitable for real-world implementation.
