目的

探讨阿尔茨海默病(alzheimer disease,AD)和轻度认知功能障碍(mild cognitive impairment,MCI)患者及正常老年人之间后扣带回皮质(posterior cingulate cortex,PCC)与全脑间有向功能连接的差异。

方法

选取2012年7月至2014年6月浙江省人民医院收治的AD患者32例(AD组)及MCI患者26例(MCI组),同期另择健康体检正常老年人58例作为正常对照组。在静息态脑功能成像的基础上,利用Granger causality分析(GCA)和独立成分分析进行有向功能连接的研究。采用单因素方差分析筛选出3组间有向功能强度有差异的连接,然后对其脑区进行感兴趣区分析;再利用DPARSF及REST软件进行静息态脑功能原始数据分析,采用t检验删选出两组间有差异的功能连接。

结果

(1)差异有统计学意义的有向连接都是单向的,即全脑到PCC有向连接的异常节点在接受PCC信息时并未出现异常,反之亦然;(2)与正常对照组比较,AD组的异常有向连接主要在默认脑网络(default mode network,DMN)脑区外;而与MCI组比较,AD组的异常有向连接则大多是在DMN脑区内,主要集中在左侧大脑半球,并呈现左右不对称的特点。

结论

PCC作为DMN脑区中一个重要的枢纽节点,在AD的进展中起着非常重要的作用。PCC的有向连接异常进一步证实AD的信息传递异常是有方向性的,且左右侧连接异常的不对称与优势大脑的使用相关。

Objective

To investigate the differences of directed functional connectivity between patients with mild cognitive impairment(MCI)/Alzheimer’s disease(AD) and healthy older.

Methods

Patients being treated at Zhejiang provincial people’s hospital from July 2012 to June 2014 were selected and divided into three groups, including Alzheimer disease group (n=32), the mild cognitive impairment group (n=26). Fitty-eight healthy olders over the same period were selected as normal control (NC) group (n=58). Based on resting state cerebral function imaging, the technique of independent component analysis (ICA) was applied to identify the brain hub nodes and Granger causality analysis (GCA) was used to explore the directed functional connectivity between PCC and the brain. One-way analysis of variance was used to screen out different directed functional connectivity among three groups, then regions of interest were analyzed in encephalic region, and original data analysis of resting state brain function was performed by DPARSF and REST,t-test was used to screen out the different directed functional connectivity between two groups.

Results

Almost all the abnormal directed functional connectivity were confirmed to be single-directed. Compared with NC group, the abnormal directed functional connectivity in AD group was in the other regions of the brain out of DMN. Compared with MCI, the most abnormal nodes in AD group were included in DMN, the abnormal direction between PCC and other regions of the brain was asymmetry. Most of the abnormal directions occur in the left hemisphere rather than the right.

Conclusion

As an important hub node in DMN, PCC plays an important role in the progress of AD. The abnormal directed functional connectivity in PCC further confirmed that abnormal signal transduction is directional, and the asymmetry of abnormal connectivity between the left and right is related to the usage of dominant hemisphere.
