- Abstract: The glymphatic system plays a crucial role in brain waste clearance, with glymphatic magnetic resonance imaging (MRI) techniques highlighting its significance in understanding neurodegenerative diseases. This review emphasizes the intricate relationship between sleep, the glymphatic system, and the onset of conditions such as Alzheimer's disease (AD), idiopathic normal pressure hydrocephalus (iNPH), Parkinson's disease (PD), and other neurological diseases. Key findings revealed that sleep disruptions can impair the glymphatic system and potentially accelerate the progression of neurodegenerative diseases. In AD, amyloid β plaque accumulation correlates with glymphatic dysfunction, while in iNPH, impaired glymphatic functionality may result in waste accumulation, such as amyloid-beta accumulation in AD. Research on PD has underscored the potential role of the glymphatic system in α-synuclein clearance. In conclusion, as we delve into the glymphatic system using MRI techniques, we anticipate a richer understanding of neurodegenerative diseases, offering prospects for innovative therapeutic interventions.
