Where Are We in Understanding Migraines?

I think we understand the evolution of the migraine attack, and we have medications that we can use to try to prevent the vasospasm or the spasm in the blood vessels, and the dilatation in the blood vessels, but that doesn't give us the reason of why people have that, and there is often a genetic component it.

Migraine runs in families, migraines runs in neurologists, somehow because it also goes with obsessive personalities, which we happen to have. But that root cause has not yet been defined.
