Peri-oral myoclonia with absences with multiple facial and upper body myoclonia: Overlap epilepsy syndrome

Abstract A 17-years old girl presented with an 8-year history of absences with peri-oral twitching, eyelid twitching and head nodding, with poor response to anti-epileptic drugs. Video EEG revealed ictal and inter-ictal generalized spike wave discharges, and absences with peri-oral (predominant), eyelid, neck and shoulder myoclonia. There was also prominent eye closure sensitivity. Conundrums regarding epilepsy syndrome classification and pathophysiology are discussed.
