What does a photosensitive seizure look like?
People with photosensitive epilepsy have seizures that are triggered by: Flashing lights. Bold, contrasting visual patterns (such as stripes or checks) Overexposure to video games.
Which type of epilepsy syndrome is linked to photosensitivity?
Versive seizures with visual hallucinations was the only focal seizure type related to photosensitivity. Of the syndromes of generalised epilepsy, only childhood absence epilepsy, juvenile myoclonic epilepsy, and epilepsy with grand mal on awakening were related to photosensitivity.
What causes blank stare seizures?
An absence seizure causes a short period of “blanking out” or staring into space. Like other kinds of seizures, they are caused by brief abnormal electrical activity in a person’s brain. An absence seizure is a generalized onset seizure, which means it begins in both sides of the brain at the same time.

There are various factors, even in people who are predisposed to seizures, that contribute to the seizure activity triggered by lights.

Can a flash of a light trigger seizures?
Photosensitivity and Seizures. For about 3% of people with epilepsy, exposure to flashing lights at certain intensities or to certain visual patterns can trigger seizures. This condition is known as photosensitive epilepsy.
