Does Brain Swelling Occur During Migraine?

I feel as though parts of my brain swell during attacks, causing severe pressure along cranial sutures.What 's really happening ?

Answer

Marra,

When you encounter a Migraine trigger, overly sensitive neruons in your brain start firing in a wave across the brain, starting a chain reaction. Levels of neurotransmitters such as serotonin and norepinephrine are knocked out of balance. Blood vessels in the brain constrict for a fraction of a second, then dilate (open wider than usual). As that happens nerves and tissues around those blood vessels become inflamed.

So, it's not a matter of the whole brain swelling, but some tissues and nerves around the blood vessels do become inflamed.

Hope this is what you needed to know,

Teri
