Partial Seizure with Aphasic Speech Arrest Caused by Watching a Popular Animated TV Program

Summary: On the evening of December 16, 1997, about 700 children across Japan were hospitalized because of convulsive seizures or vomiting experienced while watching a popular animated TV program that included blue and red stimuli that alternated at 12 flashes per second. In one case, an 11‐year‐old girl developed a hallucination in the right visual field and a subsequent cramp on the right side of her face, with aphasic speech arrest. She had no history of seizures. Her electroencephalogram (EEG) showed normal background activity and no epileptiform discharges. Intermittent photic stimulation provoked a photoparoxysmal response. Her main clinical manifestation was a TV‐induced left occipital lobe seizure spreading toward the left inferior frontal lobe. This suggested a functional link from the occipital lobe to the frontal operculum.
