  • Title: Nonconvulsive status epilepticus in eyelid myoclonia with absences--evidence of provocation unrelated to photosensitivity.
    Author: Wakamoto H, Nagao H, Manabe K, Kobayashi H, Hayashi M.
    Journal: Neuropediatrics; 1999 Jun; 30(3):149-50. PubMed ID: 10480211.
    Abstract:
    A 10-year old girl with eyelid myoclonia with absences (EMA) in whom nonconvulsive status epilepticus developed shortly after awakening is described. A video-polygraphic recording during the status showed the characteristic eye-closure provocation of eyelid myoclonia with upward deviation of the eyeballs and brief absences. Ictal EEG showed generalized polyspikes concomitant with eyelid myoclonia, while absences were accompanied by 3.5 Hz polyspike-wave complexes on EEG. This condition occurred even in total darkness as well as even after seizures precipitated by bright sunlight had been eliminated by medication. The present case suggests that the eye closure mechanism could be a more potent precipitating factor than photosensitivity in the pathophysiology of EMA.
