Answer

Gastaut described a partial epilepsy that was analogous to benign rolandic epilepsy, although the 2 syndromes have important differences. [7] In BPEOP, for example, epileptiform discharges are located in the posterior head region, most prominently in the occipital region. Typical phenomena include interictal high-voltage (200–300 µV) EEG spike and wave complexes occurring in runs with a degree of rhythmicity and a frequency of 1–3 Hz. Typically, they are blocked or prominently attenuated with eye opening. The complexes may be unilateral or bilateral and may occur independently on each side.

As in benign rolandic epilepsy, the occipital spike-wave index is activated prominently with non-REM sleep. Generalized spike and wave discharges may be present in 10% of children. Unlike benign rolandic epilepsy, which remits in most patients by age 16 years, BPEOP may persist in 20% of patients after age 20 years.
