Key Points

To develop data-driven risk algorithms using routine primary care records to detect early dementia risk and enrich prevention trials without relying excessively on age.
Analyzed routine primary care electronic health data to construct predictive algorithms for identifying individuals at high risk of developing dementia.
Evaluated model performance and discriminative capability specifically at key clinical age thresholds, such as age 65.
Existing dementia risk scores demonstrate limited discriminative capacity around the critical threshold of 65 years due to an over-reliance on chronological age.
Data-driven primary care algorithms provide refined risk stratification to support early preventative interventions and targeted trial recruitment.

Implication

Algorithm development analysis demonstrates improved dementia risk prediction in primary care populations, suggesting enhanced screening and clinical trial recruitment.

Abstract

Background: Early identification of individuals at risk of dementia is essential for effective prevention and timely intervention. Existing risk scores rely heavily on age, which limits their discriminative power at clinically relevant thresholds such as 65 years, when preventive strategies are most impactful.
