(Second sequence) Video-EEG demonstrates spontaneous symptoms resembling eyelid myoclonia with absences. These are also reproduced on request at low intermittent photic stimulation flash rates without EEG discharges. There are no abnormalities on eye closure. Higher flash rates induce photoparoxysmal discharges of polyspikes, and these are clinically manifested with axial and limb jerks without eyelid myoclonia.
