An Overview of the Electroencephalographic (EEG) Features of Epilepsy with Eyelid Myoclonia (Jeavons Syndrome)

Neurodiagn J. 2020 Jun;60(2):113-127. doi: 10.1080/21646821.2020.1750879. Epub 2020 May 5.


Epilepsy with eyelid myoclonia or Jeavons Syndrome is a unique idiopathic generalized epilepsy with onset in childhood. It is characterized by eyelid myoclonia which may be associated with absence seizures, eyelid closure-induced epileptiform discharges and/or seizures and photosensitivity. It is frequently underrecognized and misdiagnosed because it may be mistaken for some other type of generalized epilepsy or facial tic disorder. The intent of this narrative review is to focus on existing literature and highlight the distinct electroencephalographic features including characteristic eye movements, associated waveforms, interictal and ictal findings that are suggestive and characteristic of Jeavons Syndrome to aid in timely recognition of this syndrome.

Keywords: Eyelid myoclonia; Jeavons Syndrome; genetic generalized epilepsy.
