背景:一些研究表明,多发性硬化症(pwMS)患者的认知功能与结构磁共振成像(MRI)测量之间存在不同的关系。然而,关于MRI测量值与特定认知功能测试之间的相关性,目前仍存在争议.本系统综述和荟萃分析旨在综合pwMS中MRI测量与认知功能之间最一致的相关性。
方法:PubMed/MEDLINE,Embase,Scopus,和WebofScience数据库进行了系统搜索,直到2023年2月,以查找相关数据。搜索利用了与pwMS中的认知表现测试和MRI测量相关的语法和医学主题词(MeSH)。使用具有随机效应模型的R软件版本4.3.3来估计合并效应大小。
结果:回顾了13,559项研究,其中包括136个。荟萃分析表明,丘脑体积与符号数字模式测试(SDMT)r=0.47(95%CI:0.39至0.56,p<0.001,I2=88%),简要视觉记忆测试-修订-总召回(BVMT-TR)r=0.51(95%CI:0.36至0.66,p<0.001,I2=81%),CaliforniaVerbalLearningTest-II-TotalRecall(CVLT-TR)r=0.47(95%CI:0.34至0.59,p<0.001,I2=69%,),和Delis-Kaplan执行功能系统(DKEFS)r=0.48(95%CI:0.34至0.63,p<0.001,I2=22%,).
结论:我们得出结论,丘脑体积与信息处理速度(IPS)的关系最高,视觉空间学习记忆,口头学习记忆,和pwMS中的执行功能。要全面了解支撑这种关联的机制的复杂性,需要进行更多研究。
BACKGROUND: Several studies have shown the different relationships between cognitive functions and structural magnetic resonance imaging (MRI) measurements in people with multiple sclerosis (pwMS). However, there is an ongoing debate regarding the magnitude of correlation between MRI measurements and specific cognitive function tests. This systematic
review and meta-analysis aimed to synthesize the most consistent correlations between MRI measurements and cognitive function in pwMS.
METHODS: PubMed/MEDLINE, Embase, Scopus, and Web of Science databases were systematically searched up to February 2023, to find relevant data. The search utilized syntax and medical subject headings (MeSH) relevant to cognitive performance tests and MRI measurements in pwMS. The R software version 4.3.3 with random effect models was used to estimate the pooled effect sizes.
RESULTS: 13,559 studies were reviewed, of which 136 were included. The meta-analyses showed that thalamic volume had the most significant correlations with Symbol Digit Modalities Test (SDMT) r = 0.47 (95 % CI: 0.39 to 0.56, p < 0.001, I2 = 88 %), Brief Visual Memory Test-Revised-Total Recall (BVMT-TR) r = 0.51 (95 % CI: 0.36 to 0.66, p < 0.001, I2 = 81 %), California Verbal Learning Test-II-Total Recall (CVLT-TR) r = 0.47 (95 % CI: 0.34 to 0.59, p < 0.001, I2 = 69 %,), and Delis-Kaplan Executive Function System (DKEFS) r = 0.48 (95 % CI: 0.34 to 0.63, p < 0.001, I2 = 22 %,).
CONCLUSIONS: We conclude that thalamic volume exhibits highest relationships with information processing speed (IPS), visuospatial learning-memory, verbal learning-memory, and executive function in pwMS. A comprehensive understanding of the intricacies of the mechanisms underpinning this association requires additional research.
