What causes silent migraines?

ANSWER

Researchers are now looking at the aura and the pain associated with silent migraine as two distinct things. In the past, experts thought migraines were mainly a problem with blood flow in your brain: Blood vessels in the brain expand, and the swelling activates pain pathways in the nervous system. Now, they believe the headaches involve the way nerve cells are firing in your brain and how that activity relates to blood flow there.
