Answer

EEG may yield abnormal results during or immediately after an episode, showing a slowing in focal or generalized patterns. In general, nonspecific interictal EEG abnormalities, including epileptiform activity, are reported in higher frequencies in migraineurs.

Continuous ambulatory or video EEG may be useful in the rare patient with episodic confusion, hallucinations, or focal neurologic deficits; partial seizures or nonconvulsive status epilepticus are included in the differential diagnosis for the attack.
