To identify and compare the clinical manifestations of Video Game (VG) playing related to intermittent photic stimulation (IPS) and pattern stimulation in visual sensitive children.
The study included 9 children with a history of TV or VG related seizures and generalized epileptiform activity (EA) during VG provocation in the laboratory. They underwent long-term video-EEG monitoring during IPS, Pattern stimulation and VG playing on a 50 Hz TV; each patient was exposed to a standard series of 12 different VGs. Analysis of the EEGs was first done separately: type, localisation, spreading and duration of EA. Analysis of the video-images led then to the exact relationship between the patient[apos]s behaviour, EEG pattern and simultaneous play action. All discharges were taken into account.
All children showed clinical signs and the majority also symptoms (67%). The different phenomena seen during IPS and Pattern could be seen also during VG playing and were within a patient very consistent. Oral signs and dysphasia did occur during VG playing only. Focal signs were seen in eight patients and especially during VG playing. No clear relationship was found between duration of EA and clinical symptoms except for loss of consciousness and confusion.
There were basically no differences in clinical manifestations or EEG phenomena evoked by the various visual stimuli between the patients. Although all were visual sensitive (IPS, TV and VG), they had different types of seizures and epilepsies. The VG evoked signs were less intensive than during IPS. Parents and doctors should be aware of the minor ictal events to prevent major seizures provoked by VG playing.
