The BLSA postmortem study (15) included 84 participants for neuroticism, extraversion, and openness and 59 for agreeableness and conscientiousness; there was no overlap between the previous BLSA postmortem (15) and current PET sample.
Effect estimates for neuroticism and conscientiousness were from (43) while for extraversion, openness and agreeableness were from (25).
Sixty-one 18F-Florbetapir and four 18F-Flutemetamol-PET.
Rush ROS participants completed 6 items for Extraversion and 12 for each of the other traits. Openness and agreeableness were not assessed in MAP (16).
