Change of memory performance during three years. Memory was assessed by a z-scaled memory composite score for 105 participants at baseline, and when available at one (n = 78) and three years (n = 39) after baseline. The thin lines link individual memory performances at each available visit. The linear fits are presented with 95% CI (shaded areas) estimated by a linear mixed model adjusted for age, sex and education. Abbreviations: AD = Alzheimer’s disease, CI = confidence interval, HC = healthy control, MCI = mild cognitive impairment, SCD = subjective cognitive decline.
