TL;DR
This study shows that higher cognitive reserve, measured through education and mental activities, helps reduce dementia severity after stroke in older adults.
Contribution
The study demonstrates cognitive reserve as a significant protective factor against severe post-stroke dementia.
Findings
Higher cognitive reserve scores were linked to milder dementia outcomes after stroke.
Individuals with higher cognitive reserve showed better functional independence post-stroke.
Abstract
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.
