1.4.4 Migraine aura-triggered seizure

Description:

A seizure triggered by an attack of migraine with aura.

Diagnostic criteria:
  1. A seizure fulfilling diagnostic criteria for one type of epileptic attack, and criterion B below
  2. Occurring in a patient with 1.2 Migraine with aura, and during or within 1 hour after an attack of migraine with aura
  3. Not better accounted for by another ICHD-3 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 of an association with 1.1 Migraine without aura is lacking.
