摘要:

目的 探讨脑卒中后认知障碍(PSCI)患者静息态脑网络的连接特征。方法 2020年1月至2021年1月,PSCI患者24例根据简易精神状态检查和蒙特利尔认知评估量表评分分为轻度组(n=12)和中度组(n=12),纳入健康人10例(对照组)。三组被试采用全脑64通道功能性近红外光谱静息态采集6 min。采用NirSpark 1.6.12和SPSS 26.0软件进行处理。结果 中度组基于脱氧血红蛋白的半球间功能连接低于对照组(t=-2.763, P=0.024),主要位于感觉运动皮质间(F=12.674, P=0.031)。结论 PSCI患者主要表现为左右半球间功能连接水平降低,特别是左右感觉运动皮质间连接水平降低。

Abstract:

Objective To investigate the resting brain functional connectivity in patients with post-stroke cognitive impairment (PSCI).Methods From January, 2020 to January, 2021, 24 PSCI patients were divided into mild group (n=12) and moderate group (n=12) according to Mini-Mental State Examination and Montreal Cognitive Assessment scores; and other ten healthy controls (control group) were included. All the subjects were scanned with 64-channel functional near-infrared spectroscopy in resting for six minutes. The data were analyzed with NirSpark 1.6.12 and SPSS 26.0.Results Using deoxyhemoglobin, the functional connectivity between bilateral hemispheres reduced in the moderate group compared with those in the control group (t=-2.763, P=0.024), especially for the functional connectivity between sensorimotor cortexes (F=12.674, P=0.031).Conclusion Functional connectivity between hemispheres decreases in PSCI patients, especially between sensorimotor cortexes.
