Music festival lighting 'can trigger epileptic fits'

Strobe lighting at music festivals can increase the risk of epileptic seizures, researchers have warned. The Dutch team said even people who have not been diagnosed with epilepsy might be affected. Their study was prompted by the case of a 20-year-old, with no history of epilepsy, who suddenly collapsed and had a fit at a festival. The Epilepsy Society said festivals should limit lighting to the recommended levels.
