Figure 1. — Conceptual model of the relationship between dementia exposure and subjective cognitive decline (SCD). Arrows in model represent hypothetical trajectories of cognition for individuals with and without dementia exposure (e.g., individuals with SCD may maintain normal cognition or progress to objective cognitive impairment). The dashed line for Aim 2 indicates that this aim was exploratory and based on observed commonalities within included manuscripts (i.e., data-driven). Gradient represents hypothetical range of cognitive decline based on SCD status and potential modifiers of dementia exposure.
