• Flashing light
• Bright, contrasting patterns such as white bars against a black background
• Flashing white light followed by darkness
• Stimulating images that take up your complete field of vision, such as being very close to a TV screen
• Certain colors, such as red and blue

What Photosensitive Epilepsy?

What Photosensitive Epilepsy?  - Epilepsy is a brain disorder that causes recurrent seizures (more than two). A seizure is caused by abnormal electrical activity in the brain.

Epilepsy may be the result of:

Irregularity in the wiring of the brain

Umbalance of neurotransmitters (chemical messengers in the brain)

Combination of these factors

In photosensitive epilepsy, genetics also plays a role.

About one in 100 people in the U.S. have epilepsy. About 3% to 5% of those people have photosensitive epilepsy.

Children and adolescents aged 7 to 19 are more likely to have photosensitive epilepsy. Girls are affected by the condition more often than boys. But boys tend to have more seizures. That's probably because they spend more time playing video games, a common seizure trigger.
