What normally goes on in the brain prior to, during, and after a migraine? Cathy.
Entire books could be and have been written on this subject. It's quite impossible to answer it in this venue. Here's an overview: Migraineurs have overactive neurons in their brains. When they encounter a trigger, those neurons fire in a wave across the brain, starting a chain reaction. The chain reaction includes dilation of blood vessels in the brain; inflammation of nerves and tissue surrounding the brain; and disturbances in the balance of neurotransmitters including serotonin, norepinephrine, and dopamine. All the events in this chain reaction cause the various symptoms of a Migraine attack.
