Abstract

Objective: To determine the frequency and characteristics of vascular cognitive impairment (VCI) in patients with subacute stroke who underwent inpatient rehabilitation and to analyze whether cognitive function can predict functional assessments after rehabilitation.

Methods: We retrospectively reviewed the medical records of patients who were admitted to our rehabilitation center after experiencing a stroke between October 2014 and September 2015. We analyzed the data from 104 patients who completed neuropsychological assessments within 3 months after onset of a stroke.

Results: Cognitive impairment was present in 86 out of 104 patients (82.6%). The most common impairment was in visuospatial function (65, 62.5%) followed by executive function (63, 60.5%), memory (62, 59.6%), and language function (34, 32.6%). Patients with impairment in the visuospatial and executive domains had poor scores of functional assessments at both admission and discharge (p<0.05). A multivariate analysis revealed that age (β=-0.173) and the scores on the modified Rankin Scale (β=-0.178), Korean version of the Modified Barthel Index (K-MBI) (β=0.489) at admission, and Trail-Making Test A (TMT-A) (β=0.228) were related to the final K-MBI score at discharge (adjusted R2=0.646).

Conclusion: In our study, VCI was highly prevalent in patients with stroke. TMT-A scores were highly predictive of their final K-MBI score. Collectively, our results suggest that post-stroke executive dysfunction is a significant and independent predictor of functional outcome.
