[Television, children and epilepsy].
Two girls and one boy suffered seizures caused by television and other visual stimuli from 11, 12 and 12 years of age onwards, respectively. EEG recording revealed that intermittent photic stimulation (IPS) provoked epileptiform activity. Technological progress (video games, computer, disco, car, train) has considerably increased the risk for visually-induced seizures. A comprehensive clinical history with special attention to the environmental circumstances is important. For correct diagnosis an EEG with standardised IPS is necessary. Treatment consists of avoidance of strong visual stimuli. Patients may need prophylaxis with valproic acid, which should only be withdrawn after clear reduction of the EEG response to IPS. Repeating the EEG after the dosage has been lowered will help avoiding unnecessary recurrence of seizures.
