Eyelid myoclonia and absences together or independently (EEG)

This EEG is from a normal nine-year-old girl with onset of seizures at six years of age. These consisted of episodes lasting up to 45 seconds of psychomotor arrest, accompanied by head slumping either to the right or left. Video-EEG showed characteristic eye closure-related abnormalities accompanied by prominent eyelid myoclonia. She also had typical absences, both preceded by and independently of seizures with eyelid myoclonia. (Contributed by Dr. C P Panayiotopoulos.)
