Summary
Migraine neurobiology is better understood through recent discoveries linking cortical spreading depression (CSD) to trigeminovascular system activation. Genetics of familial hemiplegic migraine offer insights into CSD susceptibility in migraineurs.
Area of Science:
- Neuroscience
- Genetics
- Pathophysiology
Background:
- Migraine affects over 10% of the population as an episodic headache disorder.
- It originates from primary brain dysfunction activating the trigeminovascular system.
- The precise molecular mechanisms driving this dysfunction remain incompletely understood.
Purpose of the Study:
- To review recent discoveries in migraine neurobiology.
- To advance a unifying pathophysiological hypothesis for migraine.
- To explore the role of cortical spreading depression (CSD) in migraine.
Main Methods:
- Review of recent genetic and neurobiological findings in migraine.
- Focus on familial hemiplegic migraine (FHM).
- Analysis of molecular and cellular mechanisms underlying CSD susceptibility.
Main Results:
- Recent discoveries advance understanding of migraine's underlying mechanisms.
- Cortical spreading depression (CSD) emerges as a key phenomenon.
- Genetics of FHM provide insights into CSD susceptibility.
Conclusions:
- A unifying hypothesis for migraine pathophysiology is proposed.
- CSD plays a central role in migraine generation and maintenance.
- Understanding FHM genetics illuminates migraine mechanisms and CSD susceptibility.
