The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) for post-stroke cognitive impairment screening.

Aims: Clinical guidelines recommend stroke patients are routinely screened for cognitive impairment. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was evaluated for screening for post-stroke cognitive impairment. Methods: The RBANS and a neuropsychological test battery were administered to 60 participants recruited from acute stroke wards. Results: Using a cut-off of <70 points, the RBANS Total Index demonstrated 50% sensitivity and 100% specificity for detecting any cognitive impairment. ROC curve analysis identified an optimum total index cut-off score of <84 points (sensitivity 84%; specificity 90%). The RBANS Indices did not have acceptable sensitivity and specificity using a cut-off of <70 points. ROC curve analysis identified higher optimum cut-offs (sensitivity 79-89%; specificity 48-96%). Conclusion: The RBANS was an acceptable measure for detecting post-stroke cognitive impairment but does not include assessment of executive ability. [ABSTRACT FROM AUTHOR]
