The Glymphatic System and its Relationship to Migraine.

Area of Science:

• Neuroscience
• Neurology
• Sleep Science

Background:

• The glymphatic system is crucial for brain waste clearance.
• Migraine is a complex neurological disorder with potential links to impaired brain function.

Purpose of the Study:

• To review animal and human studies on the glymphatic system in migraine.
• To propose a model for glymphatic system function in migraine.

Main Methods:

• Critical review of existing literature.
• Analysis of animal models and human imaging studies.

Main Results:

• Animal studies indicate migraine attacks transiently impair glymphatic flow.
• Human studies show potential alterations in glymphatic function in chronic migraine, with inconsistent findings.
• The long-term impact of recurrent migraines and insomnia on glymphatic function remains unclear.

Conclusions:

• Glymphatic system dysfunction may play a role in migraine pathophysiology.
• Further longitudinal studies are needed to elucidate the relationship between glymphatic function, migraine, insomnia, and cognitive decline.
