Perioral myoclonia with absences (EEG)

The illustrated typical myoclonic absence occurred during hyperventilation with breath-counting. Note the similarities of the 3 Hz spike-and-wave ictal discharge with that of childhood absence epilepsy despite significant clinical differences documented with video EEG.
