Using PET scans of the brain, University of Michigan researchers showed that dopamine falls during a migraine headache.
This could help scientists better understand dopamine-based therapies for migraines.
Dopamine, called the brain’s feel-good neurotransmitter helps regulate emotion, motivation and sensory perception.
When migraine patients are between headaches, their dopamine levels are as stable and even as the healthy patients. But during an attack, the migraine patients’ dopamine levels fell significantly.
