Photosensitive epilepsy (PSE) is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns.

Causes[edit]

Photosensitive epilepsy is not a single condition but rather a group of conditions in which seizures are triggered by visual stimuli. The exact cause of photosensitive epilepsy is unknown, but it is believed to be a genetic disorder. The condition is often diagnosed in childhood or adolescence.

Symptoms[edit]

The symptoms of photosensitive epilepsy can vary from person to person. Some people may experience tonic-clonic seizures, while others may have absence seizures or myoclonic seizures. The seizures are often triggered by specific visual stimuli, such as flashing lights or contrasting light and dark patterns.

Diagnosis[edit]

Diagnosis of photosensitive epilepsy is typically made through a combination of medical history, description of seizures, and an electroencephalogram (EEG). During an EEG, flashing lights are often used to try to provoke a seizure. This can help confirm the diagnosis.

Treatment[edit]

Treatment for photosensitive epilepsy typically involves avoiding known triggers and taking anti-epileptic drugs. In some cases, wearing polarized sunglasses or special blue glasses can help reduce the risk of seizures.
