Abstract:
Objective:To use the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ) to analyze the cognitive function status of patients after intracranial aneurysms surgery, and to explore its effects on evaluating the cognitive function of patients after intracranial aneurysms surgery.Methods:The patients after intracranial aneurysms surgery treated in the Department of Neurology and Neurosurgery in 3 Class Ⅲ Grade A hospitals in Zhengzhou between November 2018 and June 2019 and healthy controls were selected by convenient sampling. MoCA-BJ and Addenbrooke's Cognitive Examination-Revised (ACE-R) were used to evaluate the cognitive function of 306 patients after intracranial aneurysms surgery and 47 healthy controls. After 14 days, 30 subjects from the healthy control group were randomly selected for the MoCA-BJ test again. Cronbach's α coefficient was used to analyze the internal consistency of MoCA-BJ, and the Pearson correlation coefficient test was used to retest its reliability. ACE-R was employed to determine the convergent validity of MoCA.Results:The Cronbach's α coefficient of MoCA-BJ was 0.910 ( P<0.05) , and the retest reliability was 0.879 ( P<0.01) . The correlation analysis between the total scores of MoCA-BJ and ACE-R showed a positive correlation between the two ( r=0.883, P<0.01) . The optimal cut-off value of MoCA-BJ screening for patients with mild cognitive impairment (MCI) after intracranial aneurysm surgery was 25.5, which was corresponding to 83.0% in its screening sensitivity, 87.9% in specificity, and 0.652 in the Kappa value, showing good consistency. Receiver's operating characteristic curve (ROC) analysis results showed that the area under the curve ( AUC) was 0.924 ( SE=0.019, 95% CI: 0.888-0.960, P<0.01) . Conclusions:MoCA-BJ has good internal consistency reliability, retest reliability and convergent validity, and is suitable for MCI screening of patients after intracranial aneurysm surgery.
