PSE affects approximately one in 4,000 people (5% of those with epilepsy).People with PSE experience epileptiform seizures upon exposure to certain visual stimuli. Alternating changes of different colored lights such as deep red and deep blue or lights flickering at a rapid rate of around 12Hz can precipitate photo convulsive seizures among some individuals. Your anticonvulsant selection will be based on several factors, including the type of seizure (tonic-clonic, myoclonic, or absence), how often they occur, and whether you take any other medications that could interact with anticonvulsants. Flashing lights or rapidly changing or alternating images (as in clubs, around emergency vehicles, near overhead fans, in action movies or television programs, etc.) In some instances, your medical team may expose you to a visual trigger during your EEG examination.

A seizure that is brought on by a visual trigger is described as a visual reflex seizure, a photo convulsive seizure, or a photosensitive seizure. Examples include:The frequency or speed of flashing light that is most likely to cause seizures varies from person to person. Some people with no prior history of PSE may first experience a seizure while playing a video game. They are described as tonic-clonic seizures or grand mal seizures. Again, it is also dependent on the brightness and intensity of the light, and how long the person is exposed to it.

And experts suggest that having seizures can make further seizures more likely due to the alterations in the brain’s electrical activity.
