1.4.4 Migraine aura-triggered seizure

Description:
A seizure triggered by an attack of migraine with aura.

Diagnostic criteria:
A. A seizure fulfilling diagnostic criteria for one type of epileptic attack, and criterion B below
B. Occurring in a patient with 1.2 Migraine with aura, and during, or within 1 hr after, an attack of migraine with aura
C. Not better accounted for by another diagnosis.

Comment:
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 for association with 1.1 Migraine without aura is still lacking.
