BACKGROUND/OBJECTIVES: Longitudinal studies have shown an increase in cognitive decline many years before clinical diagnosis of dementia. We sought to estimate changes, relative to "normal" aging, in the trajectory of scores on a global cognitive function test-the Cognitive Abilities Screening Instrument (CASI).
DESIGN: A prospective cohort study.
SETTING: Community-dwelling members of a U.S. health maintenance organization.
PARTICIPANTS: Individuals aged 65 and older who had no dementia diagnosis at baseline and had at least two visits with valid CASI test score (N = 4,315).
MEASUREMENTS: Average longitudinal trajectories, including changes in trajectory before clinical diagnosis in those who would be diagnosed …
