Photosensitivity is defined as a “photoparoxysmal response” (PPR) to intermittent photic stimulation (IPS) during an electroencephalogram (EEG). The PPR consists of spikes, spike-waves, or intermittent slow waves, ranging from localised occipital spikes (Grade 1) to generalised spike and wave or polyspike and wave complexes (Grade 4).
