This is an interesting topic, for sure. There are at least several threads on this topic if anyone is interested. BirdDancer's blog has interesting entries on this same topic.

I would like to mention (once again) the work Oliver Sacks, M.D. He is now deceased; yet, he has left a lot of his research available to the general public. Just one of his books is entitled: Migraine. I have gained a much better understanding of migraine and related conditions through Dr. Sack's research.

I have had disabling migraines for years. My migraines would last up to 20 days straight until my neurologist was concerned about potential brain damage from allowing migraines to go for so long. The neurologist left a standing order at the ER, asking the ER docs to interrupt the migraine.

I cannot take the usual/new migraine meds because my auras last so long. I risk actually closing the vessels further, potentially causing a stroke.

If a migraine lasts 48-72 hours, I go to the ER, where they abort the migraine.

My whole family suffers from migraines. Migraines are often familial. Many in my family suffer hemiplegic migraines, as well as various flavors of migraine.
Hemiplegic Headaches/Migraines: Symptoms, Causes, Treatments

After years of severe and very frequent migraines, this was further investigated. I had /have an autoimmune condition called "Antiphospholipid Antibody Syndrome" (aka: APS). My antibodies were attacking my own blood and were causing increased "viscosity," which was causing micro-clotting. I had to use blood thinners for 5 years, until the antibodies had disappeared. I am still checked for the presence of the antibodies at least twice a year.

I mention this because it would be very easy for my treating physicians to attribute my migraines to most anything . I have at least a few of the "conditions" which are thought/known to be related to migraines.
It is a good thing they had looked into it further. (The blood thinner did relieve my migraines.)

We have had some in-depth discussions on the relationship of migraine to BP, to Temporal Lobe Epilepsy, etc. I hope anyone interested in this topic will look up these threads. As I have mentioned, BirdDancer's blog also addresses these topics.

I would like to thank you for starting this thread and am grateful to those participating!
