摘要：

目的探讨老年脑白质病变（white matter lesion，WML）患者认知功能下降的影响因素及预测因子。方法连续登记2014年9月-2016年9月期间，郑州大学第一附属医院老年病科、神经内科门诊及住院的无认知功能障碍的WML患者，收集患者人口学资料、血管危险因素及磁共振成像检查结果。入组时行蒙特利尔认知评估量表（Montreal cognitive assessment scale，MoCA）及脑白质改变分级量表（age-related white matter changes rating scale，ARWMCRs）评定。根据1年随访时MoCA量表评分分为轻度认知功能障碍（mild cognitive impairment，MCI）组和无认知障碍组。通过单因素和多因素Logistic回归分析，判断老年WML患者认知功能下降的影响因素及预测因子。结果研究共入组118例WML患者，其中男性67例，女性51例，平均年龄（68.07±3.70）岁。1年随访时有100例（84.75％）患者保持原有认知状态不变，18例（15.25％）进展为MCI。Logistic回归分析发现高血压病[比值比（odds ratio，OR）1.47，95%可信区间（confidence interval，CI）1.08～1.93，P =0.013）]和糖尿病（OR 1.38，95%CI 1.01～1.88，P =0.042）是WML患者进展为MCI的独立危险因素，ARWMCRs评分 ≥8分（OR 1.84，95%CI 1.38～2.47，P =0.004）是WML患者进展为MCI的独立预测因子。结论高血压病和糖尿病是WML患者进展为MCI的独立危险因素，ARWMCRs评分≥8分是WML患者进展为MCI的独立预测因子。

文章导读： 本研究通过多因素分析显示高血压、糖尿病和脑白质改变分级量表评分≥8分的老年脑白质病变患者1年内出现轻度认知功能障碍危险性较高。

Abstract:

Objective To explore the influential factors and predictive factors of cognitive function decline in patients with white matter lesion (WML). Methods WML patients without cognitive dysfunction from out-patients and in-patients in departments of geriatrics and neurology in the first affiliated hospital of Zhengzhou University from September 2014 to September 2016 were registered consecutively. Their general demographic data, vascular risk factors, biochemical test results and magnetic resonance imaging were collected. Montreal cognitive assessment scale (MoCA) and age - related white matter changes rating scale (ARWMCRs) evaluation were used. According to 1 year follow-up MoCA evaluation scores, the patients were divided into group with mild cognitive impairment (MCI) and group without MCI. Single factor analysis and multi-factors Logistic regression analysis were used to find out the influential factors and predictive factors of cognitive decline in aged patients with WML. Results There were 118 cases of WML including 67 males and 51 females, with mean age of 68.07±3.70 years old. At 1 year follow-up, 100 patients’ (84.75%) cognitive state remained unchanged and the rest 18 patients (15.25%) were diagnosed with MCI. Logistic regression analysis demonstrated that hypertension [odds ratio (OR)=1.47, 95%confidence interval(CI) 1.08-1.93, P =0.013] and diabetes (OR 1.38, 95%CI 1.01-1.88, P =0.042) were independent risk factors of MCI,and ARWMCRs ≥8 scores (OR 1.84, 95%CI 1.38-2.47, P =0.004) was predictive factor of MCI. Conclusion Hypertension and diabetes are independent risk factors of MCI, and ARWMCRs ≥8 scores is the predictive factor of MCI.
