摘要:

目的 分析卒中后失语(PSA)和卒中后抑郁(PSD)自发脑活动各自的异常脑区以及共同的变化脑区,探索潜在的单病以及共病的病理学机制。
方法 系统检索建库至2025年4月19日PubMed、Embase、Web of Science、Cochrane Library、中国知网、万方数据库、维普、中国生物医学文献服务系统等数据库,纳入以PSA或PSD为研究对象,以健康人为对照组,以低频波动幅度(ALFF)、分数低频波动幅度(fALFF)和局部一致性(ReHo)为结局指标的静息态功能磁共振成像研究。提取纳入文献的差异性脑区相关结果,采用SDM-PSI V6.23 beta进行神经影像Meta分析。
结果 PSA共纳入17篇文献,涉及患者339例,对照组351例;PSD共纳入5篇文献,涉及患者102例,对照组149例。PSA左侧小脑9区、右侧颞中回、右侧脑岛的自发神经功能活动高于对照组 (P < 0.05),右侧小脑6区、左侧内侧额上回、左侧额中回、右侧前扣带与旁扣带脑回自发神经功能活动低于对照组(P < 0.05);PSD患者右侧楔叶、右侧枕上回的自发神经功能活动高于对照组(P < 0.05),左侧内侧额上回、左侧顶下小叶的自发神经功能活动低于对照组 (P < 0.05)。PSA和PSD在左侧内侧额上回的自发神经功能活动均低于对照组 (P < 0.05)。
结论 PSA的病理学机制可能涉及语言功能网络右侧代偿性亢进与左侧功能抑制,并伴有小脑的交叉性协同活动;PSD的发生可能与右侧枕叶网络功能亢进与左侧额顶叶网络功能抑制有关;左侧内侧额上回(MNI坐标x = 0, y = 26, z = 44)功能抑制很可能是PSA与PSD的语言-情绪整合通路,介导PSA与PSD共病的发生。

Abstract:

Objective To analyze the respective abnormal brain regions and commonly altered brain regions of spontaneous brain activity in post-stroke aphasia (PSA) and post-stroke depression (PSD), and to explore the potential pathological mechanisms underlying single disease and comorbidity.
Methods Literatures were retrieved from PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang data, VIP and SinoMed, from establishment to April 19th, 2025. Resting-state functional magnetic resonance imaging (fMRI) studies were included if they focused on patients with PSA or PSD, with healthy controls (HC) serving as control group, and amplitude of low-frequency fluctuation (ALFF), fractional amplitude of low-frequency fluctuation (fALFF) and regional homogeneity (ReHo) were adopted as outcome indicator. Data regarding differential brain regions were extracted from the original studies, and a neuroimaging meta-analysis was conducted using SDM-PSI V6.23 beta.
Results A total of 17 articles on PSA (339 patients and 351 HC) and five articles on PSD (102 patients and 149 HC) were included. The spontaneous brain activity in the left cerebellar area 9, right middle temporal gyrus and right insula was significantly higher in PSA patients than in HC (P < 0.05), while activity in the right cerebellar area 6, left medial superior frontal gyrus (SFGmed), left middle frontal gyrus and right anterior cingulate/paracingulate gyrus was lower (P < 0.05). For PSD, spontaneous brain activity was elevated in the right cuneus gyrus and right superior occipital gyrus compared to HC (P < 0.05), while it was reduced in the left SFGmed and left inferior parietal lobe (P < 0.05). Additionally, spontaneous brain activity in the left medial superior frontal gyrus was lower in both diseases compared to HC (P < 0.05).
Conclusion The pathological mechanism of PSA may involve a pattern of right-sided compensatory hyperfunction and left-sided inhibitory damage within the language-related network, accompanied by cross-hemispheric synergistic activity of the cerebellum. The occurrence of PSD may be attributed to hyperactivity of the right occipital network, and functional inhibition involving the left inferior parietal lobe. The inhibition observed in the left SFGmed (MNI coordinates x = 0, y = 26, z = 44) likely represents the language-emotion integration hub, mediating the co-occurrence of PSA and PSD.
