Paradoxical cognitive reserve: Cognitive trajectories from earlier to later adulthood

Background Longitudinal studies of aging are central to identifying early predictors of and mechanisms underlying late‐life cognitive decline and dementia. However, these studies typically lack cognitive data from earlier ages. It is therefore unclear how peak young adult general cognitive ability (GCA) and maintenance of GCA from young adulthood impact subsequent cognitive trajectories. To further understand GCA change from young adulthood, we...
