Topic: Risk, prevention and care in population studies

Introduction Numerous dementia risk prediction models have been developed in the past decade. However, methodological limitations of the analytical tools used may hamper their ability to generate reliable dementia risk scores. We aim to review the used methodologies. Methods We systematically reviewed the literature from March 2014 to September 2018 for publications presenting a dementia risk prediction model. We critically discuss the analytical techniques used in the literature. Results In total 137 publications were included in the qualitative synthesis. Three techniques were identified as the most commonly used methodologies: machine learning, logistic regression, and Cox regression. Discussion We identified three major methodological weaknesses: (1) over-reliance on one data source, (2) poor verification of statistical assumptions of Cox and logistic regression, and (3) lack of validation. The use of larger and more diverse data sets is recommended. Assumptions should be tested thoroughly, and actions should be taken if deviations are detected.

Key findings

Why it matters

This systematic review of 137 publications on dementia risk prediction models identified machine learning, logistic regression, and Cox regression as the most commonly used methodologies. Three major methodological weaknesses were found: over-reliance on one data source, poor verification of statistical assumptions, and lack of validation.
