Photosensitive occipital lobe epilepsy: delineation of an under-recognized reflex epilepsy syndrome according to the new ILAE criteria and long-term follow-up.

This first long-term follow-up study, utilizing newly suggested criteria of the International League Against Epilepsy, showed that POLE syndrome shows a notable overlap with GGE but also has distinctive features. POLE has a good prognosis, however, relapses are common, and photosensitivity persists as an EEG finding in the majority of patients.
