I think people with migraines are stroke prone. that's why no one wants to insure us...

I don't know if this applies to you, but my migraines and fatigue turned out to be something called Hashimoto's Encephalopathy. It is a rare complication of autoimmune thyroiditis and is treatable with steroids. It is diagnosed by elevated thyroid antibodies. Most people with HE have normal thyroid hormone levels and so are never diagnosed with thyroid disease unless they come across one of the few neurologists who knows about HE and checks the antibodies.

I have a couple of spots on my MRI- on the left side. My headaches are all on the left, too. The radiologist told me they were perivascular changes from either migraine or hypertension (which i don't have). Interestingly enough, when I was reading all the HE articles after my diagnosis, I found out that these spots are present in HE too. And under the microscope, HE patients have inflammation around the blood vessels in their brain. i.e. "perivsacular changes"

Again, I don't know if any of this applies to you, but I wanted to share my story just in case. It took 8 years to figure out my MS-like illness/CFS was actually HE.

Best Wishes!
