Abstract [en]

Background: We have recently demonstrated significant general cognitive recovery with delayed improvement of working memory 10 years after stroke in a unique longitudinal cohort.Aim: This study investigated demographic and clinical characteristics relevant to improved cognitive functions 10-year after a first-ever stroke.   

Materials and Methods: A prospective longitudinal cohort study was carried out in 38 middle-aged (mean age =54 at stroke onset) stroke survivors. Cognition was assessed thrice at one week, seven months, and ten years after the stroke. Working memory and visuospatial function were assessed with the Digit Span and Block Design subtests, respectively. General cognition was evaluated with the Mini-Mental State Examination at the two later time points. Multivariate linear regression was used to identify the variables that may significantly predict improved cognitive functions at 10-year follow-up.

Results: We found that having a full-time job prior to the stroke, suffering an ischemic (as opposed to a hemorrhagic) stroke, and having a university education predicted significantly superior general cognitive function 10 years after stroke (R2 of 0.77, p <0.001), while working memory and visuospatial function at 1 week after stroke significantly predicted their respective functions at 10-year follow-up (R2 of 0.41, p = 0.003). 

Conclusions: Our results indicate that premorbid employment status and higher education as well as having suffered from an ischemic rather than a hemorrhagic stroke might predict superior cognitive recovery among middle-aged individuals 10 years after stroke.
