Abstract
There is some evidence that social engagement may be a moderator of better cognitive ability in the context of stroke. We tested this based on people who report stroke history in UK Biobank. We compared the amounts of social engagement people reported, vs. their scores on tests like reaction time, reasoning and memory. We controlled for potential confounders like lifestyle (e.g. smoking intake), sex and age. We found relatively limited evidence of associations between cognitive scores and social engagement, suggesting that further work is needed to understand the role of psychosocial factors in moderating cognitive abilities in stroke survivors, and the potential mediators of such an effect.
