Performance on the RL/RI’s Immediate Words Recall as a function of time to diagnosis (for progressors) or on the last 5 cognitive assessments (for non-progressors). A linear function best describes the distribution for the progressors: black line. No significant model is found in the non-progressors: dotted grey line. The number of participants by group on each time point is presented. The shading area represents −1.5 and +1.5 SD of the mean performance of cognitively healthy older adults.
