Take a look at this, Many thanks to Professor G Harding (Aston University, England) for his help in drafting this leaflet.
Photosensitive epilepsy is the name given to that form of epilepsy in which seizures are provoked by
flickering light encountered in everyday life. Both natural and artificial light sources may precipitate
seizures, but the commonest precipitant appears to be television.
It is often assumed that everybody with epilepsy is photosensitive, but only 3 - 5% of people with
epilepsy are. This sensitivity occurs at a rate of approximately 1:4000 of a young (20 or under)
population. The onset of photosensitive epilepsy occurs below the age of 20 years and the condition
appears to be most common between the ages of 9 and 15. Females are more affected by
photosensitivity than males. There is evidence, too, of a genetic factor in this condition.
Various types of seizure may be induced by flickering light, but a tonic-clonic (grand mal) seizure is
certainly the most frequent type induced by television, perhaps preceded by myoclonic jerking (brief
jerking of the limbs).
If television can do this to that age group I can't begin to imagine the horrible effect it can have on children under five
