A big problem if you suffer from migraines is that no one can actually see them. There is no visible proof of your suffering. In the research world, some zones of the brain were already identified as being active during a migraine attack but different studies showed different zones.

One major study by a team in Germany used an interesting approach: they put a migraine patient in the PET scanner every morning for 30 days, migraine or not. The results are fascinating. The PET images show different zones, changing their activity in parallel with the symptoms of the patient. We can now see the migrainous anatomical cascade in the brain. Prof. Arne May called it « a string of events». It’s still more complicated than seeing a broken bone on an x-ray, but it’s a reassurance: migraines are not imaginary!
