In Reply to: seizures induced by flickering light posted by Barbie on September 07, 2000 at 21:35:01:

: 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
: years old.
