RESUMO
Introduction: Vascular cognitive impairment (VCI) and Alzheimer's disease are the most common cognitive impairment diseases in the elderly. This study aimed to apply the Repeatable Battery for Assessment of Neuropsychological Status (RBANS) scale to evaluate VCI in elderly patients and analyze its reliability and validity. Methods: We enrolled 278 VCI patients admitted to our hospital, from June 2017 to June 2018. The basic clinical information of each patient was documented, and the Mini-Mental State Examination (MMSE) and the RBANS scales were suggested to complete. Results: We found significant correlations between the RBANS total score and age, diabetes, hypertension, coronary heart disease and years of education. The internal consistency of the RBANS scale Cronbach αsuggested a good agreement with the total score and the single score at two time points. Moreover, the RBANS total score and the score of each dimension in the RBANS scale were positively correlated with the MMSE immediate memory, calculation ability, delayed memory, commanding ability, reading comprehension ability, command execution, sentence making, and pattern duplicating ability. Conclusion: In conclusion, the RBANS has good reliability and validity for the assessment of cognitive dysfunction in elderly VCI patients. It can be used as a routine clinical and research tool, for the simplicity in operation and superior acceptance.
RESUMO
INTRODUCTION: Wake up stroke starts in sleep and is a more common form of ischemic stroke. At present, it is still controversial whether wake up stroke can be treated with thrombolytic therapy. Therefore, this study will combine imaging techniques to assess the onset time of wake up stroke patients, and to analyze the imaging characteristics of wake up stroke patients and patients suitable for thrombolytic therapy within the time window. METHODS/DESIGN: This study will be a single-blinded, randomized controlled trial with 2 parallel groups. It will be conducted at North China University of science and technology affiliated hospital. DISCUSSION: There is no consistent conclusion about the pathogenesis of wake up stroke. Wake up stroke is more likely to manifest as small vessel disease. The incidence of wake up stroke patients is relatively high, and the effectiveness and safety of intravenous thrombolysis under the guidance of multimode imaging therapy in wake up stroke need to be further explored by prospective, large-scale studies.
