Cognitive Reserve and Late-Life Trajectories: A Dataset of Twenty Years of Repeated Assessment

Abstract

There is real interest in cognitive reserve and late-life trajectories right now, and real uncertainty about exactly where it delivers
the most value. We pull together the current evidence for cognitive reserve and late-life trajectories, covering the methodological,
practical, regulatory and cost angles, with an eye on where practice has genuinely settled and where researchers and reviewers
are still largely working it out for themselves. Selective, context-specific pursuit looks better supported by the evidence gathered
here than either broad rollout or blanket avoidance.
