肌萎缩侧索硬化症(ALS)患者疾病进展速度的巨大异质性可能会导致原发感觉运动区(PSMA)局部活动和功能连接之间的不一致结果。为了说明这一假设,收集并分析了38名“明确”或“可能”ALS患者(19名快速和19名缓慢,截止中位数= 0.41)和37名匹配的健康对照的静息状态fMRI(RS-fMRI)数据。在PSMA内分析低频波动(ALFF)和功能连接强度(FCS)的幅度。所有ALS患者的ALFF(p FDR <0.05)和FCS(p = 0.022)均降低。这两个指标共享约50%的方差(R = .7),并且在快速进展组(p值<.034)中均与ALS功能评定量表修订版(ALSFRS-R)呈显著正相关,但在缓慢进展组中则不相关。有趣的是,当回归出ALFF时,PSMA网络FCS,特别是半球间FCS,在缓慢进展组中与ALSFRS-R评分呈负相关(R =-0.54,p = 0.026),而不是快速进展组。总之,目前的结果表明,RS-fMRI局部活动和网络功能连接在缓慢和快速进展ALS患者中的严重程度不同。(1)ALFF降低可以解释快速进展组的严重程度(ALSFRS-R评分),但不能解释缓慢进展组;(2)网络FCS,特别是半球间FCS,显示了两种病理生理效应(即,降低的FCS)和代偿作用(即,当协变量ALFF回归时,与严重程度呈负相关),但在快速进展组中不存在。
The huge heterogeneity of the disease progression rate may cause inconsistent findings between local activity and functional connectivity of the primary sensorimotor area (PSMA) in amyotrophic lateral sclerosis (ALS). For illustration of this hypothesis, resting‐state fMRI (RS‐fMRI) data were collected and analyzed on 38 “definite” or “probable” ALS patients (19 fast and 19 slow, cut off median = 0.41) and 37 matched healthy controls. Amplitude of low frequency fluctuations (ALFFs) and functional connectivity strength (FCS) were analyzed within the PSMA. There was a decreased ALFF (p FDR <.05) and FCS (p = .022) in all ALS patients. The two metrics shared about 50% of variance (R = .7) and both showed significant positive correlation with ALS Functional Rating Scale‐Revised (ALSFRS‐R) in the fast (p values <.034) but not in the slow progression groups. Interestingly, when regressing out the ALFF, the PSMA network FCS, especially the inter‐hemisphere FCS, showed negative correlation with the ALSFRS‐R score in the slow (R = −.54, p = .026) but not the fast progression group. In summary, the current results suggest that RS‐fMRI local activity and network functional connectivity accounts for the severity differently in the slow and fast progression ALS patients. (1) The decreased ALFF could account for the severity (ALSFRS‐R score) in the fast progression group but not for slow progression group; (2) The network FCS, especially the inter‐hemisphere FCS, showed both pathophysiological effect (i.e., decreased FCS) and a compensatory effect (i.e., negative correlation with severity when the covariate ALFF was regressed out) in the slow progression group, but not in the fast group.
