An exploration of sources of bias in population models of cognitive aging and accelerated decline: A prospective cohort study

Key Points

• This research aims to identify sources of bias in population models of cognitive aging and accelerated decline.
• Used linearized models to assess cognitive decline
• Examined the impact of study design on bias
• Analyzed various analytic choices affecting results
• Found high levels of bias in linearized models
• Bias was sensitive to variations in study design
• Results indicate a need for improved modeling of accelerated decline
