I have stated for years that the causes of chronic migraine headaches and epilepsy are the same. While not generally accepted, it is consistent with current research.
The finding of a genetic link between migraines and epilepsy have been all over the news since this article hit the mainstream media earlier this month. I have had a standing Google alert for “migraines and epilepsy” for quite some time now. Nothing was on the radar screen on the Internet until this study hit.
