Orbitofrontal epilepsy: Case series and review of literature.

Background: Orbitofrontal epilepsy (OFE) is less known and is poorly characterized in comparison with temporal lobe epilepsy, partly because it is rare and possibly because it is unrecognized and therefore underestimated.

Objective: This paper aimed to better characterize seizure semiology, presurgical findings, and surgical outcomes in patients with OFE.

Methods: We retrospectively reviewed all confidently established OFE cases from six Canadian epilepsy monitoring units between 1988 and 2014, and in the literature between 1972 and 2017.
