Background: The number of patients with cognitive impairment following stroke is increasingdue to the rise in the number of stroke survivors. Health authorities highlight the need forprediction and early diagnostics. The aims of this study were to investigate if balance and mobilitymay predict cognitive impairment 1 year after stroke. Methods: The participants werepatients with first-ever stroke or transient ischaemic attack (TIA). The exclusion criteria werepre-stroke cognitive impairment and dementia. Measurements of balance comprised the BergBalance Scale (BBS) and the Figure of Eight test (Fig8). Mobility was measured by maximumwalking speed and the Timed Up and Go test. Dementia and mild cognitive impairment weremerged into a main outcome: cognitive impairment. Unadjusted and adjusted multivariatelogistic regression models were performed. Results: One hundred and eighty subjects performedbalance and mobility measures at baseline, and 158 participated in the follow-up; 13died and 9 did not complete the follow-up. Two variables made a significant contribution inthe adjusted analyses (Fig8, BBS). The strongest predictor of cognitive impairment was Fig8with an odds ratio of 1.06. Conclusion: The results of Fig8 and BBS measured in the acutephase of stroke were predictors of cognitive impairment 1 year later in this cohort of firsteverstroke or TIA.
