Hi Janet,
Migraine is currently thought to be a genetic neurologc disease caused by overactive neurons in our brains and genetics. An attack can be caused by too much or too little sleep, dehydration, certain foods and even weather pattern changes for some people.

I hope this helps.
Good luck
Nancy
