Abstract
Purpose: To analyse systematically the content of potentially seizureprovoking video sequences from different Spanish television broadcast-ers checking for compliance with current guidelines in other countries.One in 4000 subjects is at risk of having a seizure when confronted withcertain visual stimuli, often without being aware of their condition. Tele-vision is the most common cause of photosensitive seizures in the wes-tern world, but only the UK and Japan have adopted guidelines to preventthe broadcasting of video sequences that could potentially trigger sei-zures in susceptible people.Method: Television programs of all 5 national broadcasters availablevia Digital Terrestrial Television were recorded between 8 AM and 12PM on 5 consecutive days, from January 1st 2012 through January 6th2012. In addition, a channel with programming dedicated to children anda musical channel were also recorded. The video content was analysedusing a HardingFPA Flash and Pattern Analyser (Cambridge Researchsystems) for compliance with the UK Ofcom guidelines.Result: We analysed 105 hours of television programs. We found 738incidents that violated the guidelines (mean 105.43, CI95% 58.74–151.12), mostly luminance flashing (714 incidents, mean 102, CI95%55.83–148.17). Thirteen incidents involved spatial patterns and 11 redflashing. Forty-seven additional incidents considered dangerous weredetected which, although technically meeting guidelines, continued foran extended period of time and were considered dangerous.Conclusion: Spanish broadcasters seem to be unaware of the risk ofphotosensitive epilepsy. National Guidelines should be adopted to lowerthe risk of Spanish TV content triggering epileptic seizures in susceptibleviewers
