Longitudinal cognitive trajectories of subtypes of patients with prodromal AD. Predicted values of domain-specific cognitive scores were obtained from mixed effects regression models which included age, gender, and years of education as covariates, as well as random intercepts and slopes for participants to account for multiple measurements. a Memory function progression. b Executive function progression. c Visuospatial function progression. d Language function progression. Ribbons around the regression lines represent 95% confidence intervals for the fitted values
