We recently described (2) a 14-year-old girl who had a photosensitive occipital epileptic seizure followed by a status migrainosus that lasted 3 days. An EEG revealed occipital status epilepticus during her migraine attack; intravenous administration of diazepam, under continuous EEG recording, suppressed both the epileptiform discharges and headache complaints. Three days later, we were able to evoke a visual aura and her migraine during an EEG recording with Intermittent Photic Stimulatio
