For some people, seizures can be triggered by flashing or flickering lights or patterns. This is called photosensitive epilepsy. Photosensitive epilepsy affects only up to 5% of people with epilepsy.
It is standard to be tested for photosensitive epilepsy when you go through a diagnosis of epilepsy. This test involves looking at sequences of light flashes during an EEG so the doctors can see if your brain activity on the EEG recording changes when you are exposed to the light stimulation. If you are not sure whether you may be photosensitive, you can ask your GP or specialist whether you’ve had the test for it.
Triggers and causes
Triggers for seizures are not the same as causes for epilepsy. A trigger for someone to have their first seizure may be a stressful situation, but the underlying cause for that person to start having seizures may be quite different. Causes can be genetic or as a result of structural damage to the brain. See more about causes of epilepsy.
Because epilepsy can develop at any time of life, it can sometimes be difficult to work out why seizures have started. If you have a seizure, it may seem to make sense that there must be a particular cause, such as stress, or alcohol, for example. However, the likelihood of having a seizure at some point may have been there already for you, and the stress or alcohol has triggered it.
