Methods - In a 6-month prospective cohort study of 141 post-acute stroke patients, demographic and clinical data on admission, and neurological, cognitive, depressive symptoms and functional variables on admission and at 6 months after stroke were measured using the National Institute of Health Stroke Scale (NIHSS), Abbreviated Mental Test (AMT), Geriatric Depression Scale (GDS) and Barthel Index (BI). Results - On multivariate analysis, severe activities of daily living (ADL) dependence at 6 months was significantly less likely associated with higher baseline AMT score denoting better cognitive status (OR = 0.68, 95% CI 0.48-0.97 per score point) and with greater AMT change score denoting greater cognitive improvement (OR = 0.61, 95% CI 0.41-0.91 per change score point); it was also more likely with higher baseline NIHSS scores denoting severe neurological impairment, (OR = 1.74, 95% CI 1.13-2.63 per point score), NIHSS change score [denoting lesser neurological improvement (OR = 1.83, 95% CI 1.13-2.93 per unit change score)], but was not associated with baseline or change scores of GDS. Greater magnitudes of functional recovery [BI change score (standardized beta)] were associated with better baseline depressive symptoms (-0.21) and improvement (-0.31), but not with cognitive status or improvement, in the presence of other significant variables, neurological status (-0.89) and improvement (-0.65), lower baseline physical functional status (-0.85) and younger age (-0.23). Conclusions - These data suggest that improving depressive symptoms in stroke patients may accelerate functional recovery, but the level of physical functioning achieved post-stroke is determined by neurological and cognitive factors, consistent with the evidence that improvement of depressive symptoms through therapeutic intervention is limited by cognitive impairment. © 2007 Blackwell Munksgaard.||Source Title:||Acta Neurologica Scandinavica||URI:||http://scholarbank.nus.edu.sg/handle/10635/108442||ISSN:||00016314||DOI:||10.1111/j.1600-0404.2006.00751.x|
