What Have We Learned From Brain Functional Connectivity Studies in Migraine Headache?

Area of Science:

• Neuroscience
• Medical Imaging
• Neurology

Background:

• Headache syndromes, particularly migraine, have seen advancements due to neuroimaging.
• Previous research often focused on isolated brain regions.
• A shift towards understanding brain-wide networks is crucial for migraine research.

Purpose of the Study:

• To review neuroimaging studies on the functional organization and connectivity of the migraine brain.
• To explore how functional connectivity research enhances understanding of migraine mechanisms.
• To discuss the translation of connectivity findings into patient benefits.

Main Methods:

• Discussion of data sources and study designs in functional neuroimaging of migraine brain connectivity.
• Review of existing findings from functional connectivity studies in migraine.
• Analysis of network-based approaches versus single-region focus.

Main Results:

• Functional connectivity studies have broadened the understanding of migraine mechanisms.
• Migraine is increasingly viewed as a disorder of brain networks rather than isolated regions.
• Interactions among brain regions are key to understanding migraine pathophysiology.

Conclusions:

• Functional neuroimaging, especially connectivity studies, has significantly advanced migraine research.
• A network perspective is essential for comprehending migraine's complexity.
• Translating connectivity insights into clinical applications holds promise for migraine patient care.
