Question: What is a Migraine Seizure?
Answer: Simply put, a migraine seizure is an epileptic seizure that follows a migraine with aura. According to the International Headache Society, to be a migraine seizure it must meet two criteria:
  • It must fit the definition for a migraine with aura, and
  • An epileptic seizure must occur within one hour of the migraine aura.

An aura often involves some sort of change in a person's vision, such as zigzagging lines, flashing lights, or a temporary blind spot.
