To evaluate and compare the predictive validity of the ANU-ADRI, LIBRA, and CAIDE risk prediction models alongside a novel hybrid model for identifying dementia and cognitive impairment.
Assessed the performance of three established risk prediction tools (ANU-ADRI, LIBRA, and CAIDE) in an Australian cohort.
Developed and evaluated a new hybrid risk assessment model combining predictive elements.
ANU-ADRI and LIBRA demonstrated better predictive capability than CAIDE for identifying high-risk individuals.
ANU-ADRI systematically overestimated dementia risk, whereas LIBRA underestimated risk.
The newly designed hybrid model achieved higher predictive performance than the individual models, though independent longitudinal validation remains necessary.

Implication

Cohort study reveals differences in dementia risk prediction accuracy in an Australian cohort, highlighting the superior performance of a hybrid model.

Abstract

ANU-ADRI and LIBRA were better dementia prediction tools than CAIDE for identification of high-risk individuals in this cohort. ANU-ADRI overestimated and LIBRA underestimated the risk. The new hybrid model had a higher predictive performance than the other models but it needs to be validated independently in longitudinal studies.
