I don't know if there's a link or if it's a side effect of certain medications, all I know is that I started getting migraines after starting my medications (Seroquel, abilify, klonopin, Lamictal and propranolol), I get them about 5 times a year. I only started getting them after starting Abilify (the last med that was started) and headache is listed as a side effect of that.
