| - | Photosensitive epilepsy is a type of epilepsy in which seizures are triggered by flashing lights or other visual stimuli. These seizures can range in severity from brief periods of dizziness or disorientation to more severe tonic-clonic seizures, which involve muscle spasms and loss of consciousness. | + | Photosensitive epilepsy is a type of epilepsy in which seizures are triggered by flashing lights or other visual stimuli. These seizures can range in severity from brief periods of dizziness or disorientation to more severe tonic-clonic seizures, which involve muscle spasms and loss of consciousness. Photosensitive epilepsy is relatively uncommon, accounting for about 3% of all cases of epilepsy. However, the actual prevalence may be somewhat higher, as some people with photosensitive epilepsy may not be aware that their seizures are triggered by visual stimuli. |
| Strobe lights, also known as flashing lights, can potentially induce seizures in people with photosensitive epilepsy. The frequency of the flashing can play a role in the likelihood of a seizure being triggered. Generally, flashing lights with a frequency of around 20 flashes per second or higher have a greater potential to trigger seizures in people with photosensitive epilepsy. | Strobe lights, also known as flashing lights, can potentially induce seizures in people with photosensitive epilepsy.

| The exact mechanism behind the induction of seizures by flashing lights is not fully understood, but it is thought to involve changes in brain activity that are triggered by the flashing stimuli. In people with photosensitive epilepsy, the visual system is particularly sensitive to certain patterns of light, such as flashing or flickering lights. When the brain is exposed to these stimuli, it can lead to changes in brain activity and the development of a seizure. | The exact mechanism behind the induction of seizures by flashing lights is not fully understood, but it is thought to involve changes in brain activity that are triggered by the flashing stimuli.
