Abstract
Background: We aim to assess the effect of social networks on risk of cognitive impairment in patients following stroke.
Methods: 1135 stroke patients from 1995 to 2014 in the South London Stroke Register (SLSR) were included in the study. Cognitive status was assessed by the Mini-Mental State Examination (MMSE) and Abbreviated Mental Test (AMT). Social networks were measured using the social networks questionnaire in SLSR which was further developed into scores for domains of social networks (emotional support, social engagement and instrumental support) and a total social networks score. Multivariate logistic regression models adjusted for socio-demographics, case-mix, acute stroke care and risk factors prior to stroke were used for analysis of the association between social networks and cognitive impairment at 3 months and 1 year after stroke.
Results: Higher levels of social engagement were significantly associated with reduced risk of cognitive impairment at 3 months after stroke (odds ratio (OR): 0.30 to 0.79). On 1 year follow-up, higher levels of social engagement and emotional support were shown significantly associated with reduced risk of cognitive impairment (OR: 0.14 to 0.56, and 0.25 to 0.27, respectively). Also, the total social network score at 1 year was significantly associated with reduced risk of cognitive impairment (OR: 0.87 (95% CI: 0.79–0.97)).
Conclusions: Social engagement is significantly associated with cognitive impairment at both 3 months and 1 year after stroke. Social engagement, emotional support and overall better social networks are associated with reduced risk of cognitive impairment at 1 year after stroke.
