年龄相关性脑白质改变(age-related white matter changes,ARWMC)被认为是小动脉硬化性小血管病的表现,与高龄和血管危险因素有关.脑白质改变(white matter changes,WMC)已被公认为脑小血管病的表现之一,是老年人认知损害和功能丧失的病理学基础.研究表明,但WMC发展到一定程度时,会出现许多临床症状,包括认知损害、痴呆、抑郁、步态障碍、尿失禁,并与卒中和死亡风险增高相关. 相似文献

目的探讨高龄(≥80岁)糖尿病患者缺血性脑白质病变(WML)严重程度及其相关危险因素分析。方法选择安徽医科大学第三附属医院神经内科及干部病房住院的行头颅MRI检查的缺血性WML患者202例,分为糖尿病组105例和非糖尿病组97例,糖尿病组根据年龄相关性脑白质改变(ARWMC)评分为WML轻度患者(1~4分)35例、中度患者(5~8分)46例和重度患者(≥9分)24例。收集患者临床基线资料,采用Kendall等级相关分析,采用多因素logistic回归分析WML相关危险因素。结果糖尿病组空腹血糖、餐后2 h血糖、ARWMC评分明显高于非糖尿病组,HDL-C水平明显低于非糖尿病组(P<0.05)。糖尿病组不同程度WML患者年龄、空腹血糖、餐后2 h血糖及糖化血红蛋白(HbA1c)水平比较,差异有统计学意义(P<0.05,P<0.01)。轻度、重度及重度患者随症状加重其空腹血糖、餐后2 h血糖及HbA1c水平明显升高(P<0.05)。与轻度患者比较,中度和重度患者年龄更高,重度患者糖尿病病程更长(P<0.05)。多因素logistic回归分析显示,年龄、HbA1c水平升高是缺血性WML严重程度的独立危险因素(95%CI=0.128~0.454,P=0.000;95%CI=1.941~5.623,P=0.000)。所有缺血性WML患者,年龄与WML严重程度呈正相关(P=0.000)。糖尿病患者年龄、HbA1c水平、糖尿病病程与缺血性WML严重程度呈正相关(P<0.05,P<0.01)。在校正高血压、血脂、尿酸水平等危险因素后,糖尿病病程与缺血性WML严重程度的无关(P=0.210)。结论年龄是缺血性WML的独立危险因素,在糖尿病患者中,HbA1c水平可能与缺血性WML严重程度相关。 相似文献

Background: Traditional risk factors such as hypertension explain some but not all the risk factors for leukoaraiosis or deep white matter lesions (DWML). A previous study suggested that a lower blood concentration of tryptophan was a unique factor related to DWML and the present study sought to further characterize this aspect as one of the presumed non-vascular risk factors for DWML in subjects without hypertension.
Methods: Data from 383 community-dwelling elderly subjects (121 males, 262 females; mean age, 67.1 years) were analyzed. Participants underwent standardized evaluations including a neurological examination, complete blood chemistry panel, ECG, magnetic resonance imaging (MRI), and plasma amino acid measurements. MRI scans used a 1.0-tesla superconducting magnet with the spin-echo technique and fluid-attenuated inversion-recovery sequences.
Results: The MRI study revealed that greater age (odds ratio [OR] 1.94/10 years), hypertension (OR 1.86), higher cholesterol (OR 1.49/mmol/L), and lower plasma tryptophan concentrations (OR 0.71/10 µmol/L) were independent variables related to DWML. When the same logistic model was applied to lacunar infarction on MRI, age, male gender, and hypertension, but not cholesterol or tryptophan, were associated with lacunar infarction. The association between lower plasma tryptophan concentrations and DWML was significant in normotensive subjects, but not in hypertensive patients.
Conclusions: The results of the MRI study suggest that lower plasma tryptophan concentrations contribute to the development of DWML, especially in subjects without classical vascular risk factors such as hypertension. To plan an effective strategy for preventing DWML, future study is needed to elucidate the mechanism by which lower tryptophan concentrations induce DWML. 相似文献

OBJECTIVES: To study the relation between serum levels of carotenoids and white matter lesions (WMLs) on magnetic resonance imaging (MRI). DESIGN: Evaluation of cross-sectional data from a cohort study. SETTING: The Rotterdam Scan Study. PARTICIPANTS: Two hundred and three nondemented older persons, age 60 to 90, from the Rotterdam Scan Study. MEASUREMENTS: Serum levels of carotenoids were determined. WMLs on MRIs were rated separately into periventricular and subcortical WMLs. Odds ratios (ORs) for the presence of severe WMLs (upper decile) were calculated per standard deviation (SD) increase in serum carotenoid level and per SD increase in overall carotenoid serum level. Effect modification by smoking status was studied through stratified analyses. RESULTS: Increasing levels of all the separate carotenoids were associated with less severe periventricular WMLs, which reached statistical significance for the overall carotenoid serum level (OR 0.4 per SD; 95% confidence interval (CI) = 0.2-0.9). We found no association between carotenoid levels and the presence of severe subcortical WMLs (OR 1.2 per SD; 95% CI = 0.7-2.0). The association of carotenoid levels with severe periventricular WMLs was more marked in those who ever smoked (OR 0.1 per SD; 95% CI = 0.0-0.9) than in those who had never smoked (OR 0.9 per SD; 95% CI = 0.4-2.1). CONCLUSIONS: These findings are compatible with the view that high levels of carotenoids may protect against WMLs in the periventricular region, in particular in smokers. Longitudinal studies with repeated measurements of both carotenoids and WMLs are necessary to explore this hypothesis further. 相似文献
