Abstract

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with no effective treatment or cure. ALS is characterized by the death of lower motor neurons (LMNs) in the spinal cord and upper motor neurons (UMNs) in the brain and their networks. Since the lower motor neurons are under the control of UMN and the networks, cortical degeneration may play a vital role in the pathophysiology of ALS. These changes that are not apparent on routine imaging with CT scans or MRI brain can be identified using modalities such as diffusion tensor imaging, functional MRI, arterial spin labelling (ASL), electroencephalogram (EEG), magnetoencephalogram (MEG), functional near-infrared spectroscopy (fNIRS), and positron emission tomography (PET) scan. They can help us generate a representation of brain networks and connectivity that can be visualized and parsed out to characterize and quantify the underlying pathophysiology in ALS. In addition, network analysis using graph measures provides a novel way of understanding the complex network changes occurring in the brain. These have the potential to become biomarker for the diagnosis and treatment of ALS. This article is a systematic review and overview of the various connectivity and network-based studies in ALS.

肌萎缩侧索硬化症的脑连通性和网络分析。
肌萎缩性侧索硬化症(ALS)是一种致命的神经退行性疾病,没有有效的治疗或治愈方法。ALS的特点是脊髓下运动神经元(LMNs)和大脑上运动神经元(UMNs)及其网络的死亡。由于下部运动神经元受UMN及其网络的控制,皮质变性可能在ALS的病理生理中起着至关重要的作用。这些在常规CT扫描或MRI脑成像中不明显的变化可以通过扩散张量成像、功能性MRI、动脉自旋标记(ASL)、脑电图(EEG)、脑磁图(MEG)、功能性近红外光谱(fNIRS)和正电子发射断层扫描(PET)扫描等方式来识别。它们可以帮助我们生成大脑网络和连通性的表示,这些网络和连通性可以被可视化和解析,以表征和量化ALS的潜在病理生理。此外,使用图测量的网络分析提供了一种理解大脑中发生的复杂网络变化的新方法。这些有可能成为ALS诊断和治疗的生物标志物。这篇文章是一个系统的回顾和概述各种连接和网络为基础的研究ALS。
