As with a lot of questions surrounding migraine and the causes of migraine, scientists can’t say for certain what the answer is. There are generally accepted theories though, and the most popular of these when it comes to migraine aura cause is that it has something to do with serotonin and dopamine.
The thought is that the way serotonin and dopamine chemicals regulate brain function ceases to work as it should, which causes the body’s immune system to overreact. The result is that a mass of immune response cells rush through blood vessels to the brain, which causes the vessels to swell. This then means that even more chemicals are released to help control the vessels’ muscles which then constrict. Then comes the throbbing head pain.
So while there is no definitive answer yet, there is a strong theory under investigation. Which is an important step because when scientists do know what causes migraine aura, the solution to the problem will be that much easier to find.
