Paroxysmal eyelid movements: A confusing feature of generalized photosensitive epilepsy

Abstract

Background: Persistent, frequent, nonepileptic paroxysmal eyelid movements were observed in 19 children and adults with well-controlled generalized epilepsy. Methods: Patients were identified from five epilepsy centers. Results: Seventeen patients were female and two male. All had generalized photosensitive epilepsy requiring antiepileptic drugs (AEDs). In two children, paroxysmal eyelid movements began 2 to 4 years before their epilepsy was noted; in the remainder, it was noted when epilepsy was first diagnosed. Age at last follow-up was 8 to 38 years (average 21 years) with average follow-up of 9 years. All patients showed photosensitive generalized spike-wave discharges on EEG. Paroxysmal..
