Abstract

The glymphatic system is a brain-wide perivascular pathway that functions similarly to the lymphatic system in the periphery of the body, playing a crucial role in removing waste from the brain. Although impaired glymphatic function has a well-known relationship with neurodegenerative diseases through abnormal protein accumulation, it is also associated with migraine. While still in its nascent phase, research on the glymphatic system in migraine patients is gradually increasing. This systematic literature review focuses on studies investigating the glymphatic system in migraineurs. Furthermore, it examines the methods used to evaluate the glymphatic system in these studies and their main findings.
