Cohort findings reveal stable dementia incidence in rural Spain, suggesting diagnostic issues rather than true prevalence changes.
The incidence increased only when death certificate diagnoses were included; active follow-up suggested stability. This higher incidence may reflect older age structure, lower educational attainment/cognitive reserve, heavier vascular risk burden, and constrained diagnostic access that shifts detection to death certification.
