“There is a connection between Migraines and epilepsy, but exactly what that connection is has yet to be fully understood.
No, Migraines are not a form of epilepsy or a seizure disorder. Migraine is an independent genetic neurological disease.”

They are connected. Lots of people with seizures have migraines.
My daughter was diagnosed with migraines at first, but then was later changed to epilepsy after she had a grand mal and an abnormal EEG.
A lot of the anti-epileptic drugs also treat migraines.
A lot of the triggers (flickering lights, aspartame, caffiene) for seizures also trigger migraines.
