title: Correlation Between the Revised Brain Symmetry Index, an EEG Feature Index, and Short-term Prognosis in Acute Ischemic Stroke.
abstract: OBJECTIVE
  The present study aims to investigate the correlation between EEG features and short-term prognosis in patients who have experienced an acute ischemic stroke.
  
  
  METHODS
  The present study included 29 patients who had experienced an acute ischemic stroke and were treated at the Beijing Dongzhimen Hospital affiliated with Beijing University of Chinese Medicine between January 2010 and January 2012. Patients were evaluated using the revised Brain Symmetry Index (r-BSI), National Institutes of Health Stroke Scale, and Glasgow Coma Scale. Functional outcomes were assessed 21 days after admission using the Barthel Index and modified Rankin Scale. Two groups were created based on the Barthel Index (<60 vs. ≥60) and modified Rankin Scale (<3 vs. ≥3).
  
  
  RESULTS
  Significant differences were observed in r-BSI, National Institutes of Health Stroke Scale, and Glasgow Coma Scale scores between the two groups. Poor functional outcomes were associated with higher r-BSI and National Institutes of Health Stroke Scale scores as well as lower Glasgow Coma Scale scores in comparison with those obtained for patients with good prognosis. Logistic regression analysis revealed that r-BSI scores at admission exhibited significant negative correlation with Barthel Index scores (-2.070, P = 0.049) and significant positive correlation with modified Rankin Scale scores (2.256, P = 0.033).
  
  
  CONCLUSIONS
  The r-BSI may be a valuable prognostic tool in the prediction of short-term outcomes for patients who have experienced acute ischemic stroke.
  
  
  CONCLUSIONS
  The early prediction of functional outcomes after stroke may enhance clinical management and minimize short-term mortality.
