Various types of seizures can be triggered by flashing or flickering light however, the most common is a tonic-clonic (convulsive) seizure.
Many people think that everybody with epilepsy has photosensitive epilepsy. In fact, it’s not common with approximately five in every 100 people experiencing this condition. This type of epilepsy usually begins before the age of 20. It is most common between the ages of seven and 19 with more girls than boys affected. Photosensitive epilepsy often remits by adulthood.
Medication is an effective treatment and desensitising techniques have been used successfully with some photosensitive epilepsies.
