If you suffer from migraines, you don’t need me to explain how head-splittingly awful they are. There are about 300 million people who fall prey to migraines, and the World Health Organization recently described it as one of the four most disabling chronic medical conditions. Yet doctors still don’t know much about what causes them.
However, research derived from brain-imaging technology is shedding new light on the disorder, and John Rennie joins us to explain the findings, and the potential for better treatment options. He’s editor-in-chief of Scientific American magazine, which has an article about migraine research in its new issue.
