APOE and Alzheimer disease: Like the SCD group, healthy relatives often showed model preferences and activity patterns qualitatively identical to those of HCs (see e.g.,Figs. 2,3, and6), consistent with AD relatives in the DELCODE study not significantly differing from HCs in terms of MMSE total (seeTable 1), NPT global score (Wolfsgruber et al., 2020), the PACC5 neuropsychological composite score (Papp et al., 2017), or ApoE genotype (seeSoch et al., 2024).
