What causes migraines?

CAUSE and TRIGGERS. Migraines may be caused by changes in the brain/ trigeminal nerve=pain pathway. Serotonin (a brain chemical) imbalance may also play a role as serotonin levels drop during attacks. Many known triggers are noted: alcohol, cheeses, chocolate, msg, salty foods, 'diet sodas', 'skipping meals', 'lack of sleep', pms-homones, stress, strong odors, bright lights, physical exertion... Just to name a few.
Not known. While the cause for migraine is not known yet, it appears that the brain of migraine sufferers is different than those who do not get headaches. It seems that the migraine brain responds differently to stimulus in such a way as to cause incresed nerve activity leading to pain. While certain "triggers" appear to be responsible for headache onset, they are not proven. Migraine seems to be genetic.
