We described the clinical features of four cases who had "Pokemon" (television animation program) -induced seizures. Two cases showed photoparoxysmal response (PPR) during intermittent photic stimulation (IPS) and no spike discharges at rest on electroencephalography (EEG). One case had seizures with visual auras and showed spike discharges on the regions of bilateral occipital lobes at rest but no PPR. The last case had generalized tonic clonic seizures and showed bilateral synchronous generalized spikes and slow waves at rest without PPR during IPS. Therefore, the former two cases were recognized as situation-related seizures, and the remaining two cases were recognized as symptomatic occipital lobe epilepsy and idiopathic generalized epilepsy. These cases indicated that seizures were strongly provoked by red and blue flashing stimulation alternating at a frequency of 12 Hz rather than IPS.
