NOTE. Mean ± standard deviation. APOE ɛ4 (−/+) represent individuals who possessed at least one copy of the APOE ɛ4 allele. Handedness was assessed via the Edinburgh handedness scale. Education and employment were assessed via SSAGA_Education and SSAGA_Employment, respectively, as described in the Young Adult Human Connectome Project data dictionary: https://wiki.humanconnectome.org/display/PublicData/HCP+Data+Dictionary+Public-+Updated+for+the+1200+Subject+Release.
