The glymphatic system and multiple sclerosis: An evolving connection

Mult Scler Relat Disord. 2024 Mar:83:105456. doi: 10.1016/j.msard.2024.105456. Epub 2024 Jan 21.

Abstract

Multiple sclerosis (MS) is a complex autoimmune disorder that affects the central nervous system, resulting in demyelination and an array of neurological manifestations. Recently, there has been significant scientific interest in the glymphatic system, which operates as a waste-clearance system for the brain. This article reviews the existing literature, and explores potential links between the glymphatic system and MS, shedding light on its evolving significance in the context of MS pathogenesis. The authors consider the pathophysiological implications of glymphatic dysfunction in MS, the impact of disrupted sleep on glymphatic function, and the bidirectional relationship between MS and sleep disturbances. By offering an understanding of the intricate interplay between the glymphatic system and MS, this review provides valuable insights which may lead to improved diagnostic techniques and more effective therapeutic interventions.

Keywords: Glymphatic system; MS; Magnetic resonance imaging, MRI; Multiple sclerosis; Perivascular space.
