Analytical cohort study on cognitive reserve as a predictor of post-stroke dementia severity

The role of cognitive reserve in determining the severity of dementia following a stroke in individuals aged 55 and above is of interest. Hence, a total of 128 stroke survivors were followed for 12 months post-event, with cognitive reserve quantified using education level, occupational attainment and engagement in cognitive activities. Higher cognitive reserve scores were associated with milder post-stroke dementia outcomes and better functional independence. Thus, we show that cognitive reserve is a significant protective factor against severe cognitive decline after stroke.
