Despite the considerable progress made towards understanding ALS pathophysiology, several key features of ALS remain unexplained, from its aetiology to its epidemiological aspects. The glymphatic system, which has recently been recognised as a major clearance pathway for the brain, has received considerable attention in several neurological conditions, particularly Alzheimer’s disease. Its significance in ALS has, however, been little addressed. This perspective article therefore aims to assess the possibility of CSF contribution in ALS by considering various lines of evidence, including the abnormal composition of ALS-CSF, its toxicity and the evidence for impaired CSF dynamics in ALS patients. We also describe a potential role for CSF circulation in determining disease spread as well as the importance of CSF dynamics in ALS neurotherapeutics. We propose that a CSF model could potentially offer additional avenues to explore currently unexplained features of ALS, ultimately leading to new treatment options for people with ALS.

定义脑脊液在 ALS 病理生理学中的新功能。

尽管在理解 ALS 病理生理学方面取得了相当大的进展,但 ALS 从病因学到流行病学方面的几个关键特征仍然无法解释。类淋巴系统最近被认为是大脑的主要清除途径,在多种神经系统疾病,特别是阿尔茨海默病中受到了相当多的关注。然而,它在 ALS 中的重要性却很少被提及。因此,这篇前瞻性文章旨在通过考虑各种证据,包括 ALS-CSF 的异常成分、其毒性以及 ALS 患者脑脊液动力学受损的证据,评估 CSF 在 ALS 中发挥作用的可能性。我们还描述了脑脊液循环在确定疾病传播中的潜在作用以及脑脊液动态在 ALS 神经治疗中的重要性。我们认为,CSF 模型可能会提供额外的途径来探索目前无法解释的 ALS 特征,最终为 ALS 患者带来新的治疗选择。
