- A seizure fulfilling diagnostic criteria for one type of epileptic attack, and criterion B below

Migraine and epilepsy are prototypical examples of paroxysmal brain disorders. While migraine-like headaches are quite frequently seen in the epileptic postictal period, sometimes a seizure occurs during or following a migraine attack. This phenomenon, sometimes referred to as migralepsy, is a rare event, originally described in patients with 1.2 Migraine with aura. Evidence of an association with 1.1 Migraine without aura is lacking.
