Area of Science:

  • Neuroscience
  • Pharmacology
  • Physiology

Background:

  • Migraine is a complex neurological disorder with significant unmet therapeutic needs.
  • Understanding migraine pathophysiology is crucial for developing effective treatments.

Purpose of the Study:

  • To review commonly used experimental models for studying migraine.
  • To highlight their role in elucidating the pathophysiological mechanisms of migraine.
  • To discuss their utility in exploring novel drug mechanisms.

Main Methods:

  • Focus on animal models of migraine.
  • Analysis of trigeminovascular system activation.
  • Assessment of sphenopalatine ganglion, superior sagittal sinus, dura mater, and blood vessel responses.
  • Inclusion of cortical spreading depression studies.

Main Results:

  • Experimental models reveal key pathophysiological aspects of migraine.
  • Commonly observed consequences include protein extravasation, neuropeptide release, and changes in cerebral blood flow (rCBF) and neuronal activity.
  • Cortical spreading depression models correlate with human migraine aura.

Conclusions:

  • Experimental models are instrumental in advancing our understanding of migraine pathophysiology.
  • These models provide a foundation for investigating new therapeutic strategies and drug mechanisms for migraine.
