Summary
Neuroimaging advances reveal migraine mechanisms, including aura and pain pathways. Studies show increased brain excitability between migraine attacks.
Area of Science:
- Neurology
- Neuroscience
- Pain Medicine
Background:
- Migraine mechanisms were poorly understood until recent neuroimaging advancements.
- Understanding migraine aura and pain is crucial for effective treatment.
Purpose of the Study:
- To discuss the mechanisms of migraine aura and pain.
- To review studies on brain hyperexcitability in migraine patients.
Main Methods:
- Review of recent neuroimaging studies.
- Analysis of interictal research on migraine pathophysiology.
Main Results:
- Neuroimaging has shed light on the underlying mechanisms of migraine.
- Evidence suggests hyperexcitability in the migraine brain during interictal periods.
Conclusions:
- Recent neuroimaging techniques have significantly improved our understanding of migraine.
- Hyperexcitability may be a key factor in migraine development and recurrence.
