Kanye West's video for "All of the Light" comes with a warning, saying it could trigger seizures and that "viewer discretion is advised."

The phenomenon has also been known to occur in people playing video games.

Jessica Solodar, a Newton, Mass., mother, began blogging and trying to raise awareness about the problem after her daughter, Alice, suffered a seizure while playing a game.

"It takes an event like this 'Twilight' movie to get people to even consider the fact that we have a public health problem that is much more extensive than people realize," she says.

Solodar said Alice, who is 18 now, had, like many teenagers, wanted to go see "Breaking Dawn," but doesn't want to go now that she's heard about the seizures. "She'd rather not take any chances," she said.

The film's production company and American distributor, Summit Entertainment, declined to comment on the reported seizures.

Though Ting and epilepsy experts advise anyone prone to photosensitivity to skip the film, they have some advice for those who go anyway and might begin to feel ill.

"If people are seeing the film and they start to feel funny, they can stop that by not continuing to look at the screen," Ting says, adding that closing one's eyes might not be enough. "They need to block it with their hands. You really have to cover it completely."
