Brain imaging migraine patients
Migraine patients look exactly the same as individuals without headache. Surprisingly, brain imaging studies show that appearances can be deceiving. Collaborative work by the Bridge and Cader groups’ show that there are widespread changes in connections between pain and sensory regions of migraines and that brain chemistry even between attacks is altered. Work is ongoing to understand the basis of these changes and to identify mechanism of how light might trigger migraine in some people.
