I was watching a series of careful Japanese cartoons when the lights and flashes of colors caused his crisis. He was 11. Shortly after she was diagnosed with photosensitive epilepsy, a disorder that can have one of every 4,000 people worldwide. However, epilepsy sufferer Vanessa is the end result of another medical condition that affects approximately 1.5% of the population: photosensitivity by visual stimuli, which is triggered by high contrast visual motifs, such as flashes, colored lights, stripes, networks, grids ... common parts in television, movies, video games or disco lighting, which can cause in sensitive people from unpleasant sensations, dizziness and migraines to epilepsy. Only the United Kingdom and Japan have issued rules prohibiting such images They came up to a dozen people in the UK recently. After seeing an advertisement for the Citroen car brand. The campaign, which aired on several television as ITV or Sky to promote the new Citroën DS4, shows a rapid succession of flashes , lights and images with the word Yes . These stimuli can be harmful for people with this type of photosensitivity, explains Jaime Parra, neurologist coordinator of epilepsy hospitals Zarzuela and Our Lady of the Rosary. After complaints from viewers, the regulatory body for UK television advert vetoed. Only this country and Japan also have a factory-Disney rules governing audiovisual content to prevent the emission of such stimuli. All films, television shows and ads must follow certain rules, such as no more than three flashes on an image, do not use red flashes or not occupy more than a quarter of the screen with geometric patterns. Terms that make the images will be secure. In addition, the legislation requires that when emissions are live, programs should contact if there is a possibility that images that may be harmful to those affected by this disease are issued. Citroëns announcement was analyzed, as everything that is published in the British chain with a computer program that detects images that violate the rule. But the system has proven not to be infallible. Repeated patterns ◾To certain visual stimuli, people with photosensitivity may suffer migraines or epilepsy. ◾Flashes, colored lights and repetitive patterns like stripes or grids may provoke crisis. ◾Ads from one of Citroën UK, using certain elements, film-like Avatar or Babel - or TV shows have caused cases. Examples such as the brand campaign car any, and varied worldwide: videos music-as some of Rihana, Gnards Barkleys or Kanye West-, video games and movies like Avatar or Babel , with which cases of severe headaches were detected. In late 2011, the American Foundation for the Study of Epilepsy warned that a scene from Dawn , the final film in the saga Twilight , crisis could trigger photosensitive epilepsy patients. The sequence, which chronicles the birth of the protagonist, is awash with red, white and black images interspersed. Several cases due to the effect of flashes and what is called strobe is detected, a spokesman for the foundation. The problem, says the Spanish Society of Neurology , is especially when a person is diagnosed suffers a crisis. And there are. There are an estimated 800,000 people in the U.S. photosensitive, but many do not. Migraines or dizziness, but have not associated with the images or the lights, says Parra. In fact, at first, when these stimuli are affected feel pleasurable sensations that are actually small seizures. Until you reach a tough crisis, he added. It happens mostly to children, attracted by these first impressions, glued to the TV. And the crisis is that this disease usually begin at five years and exacerbated during adolescence. So where children are more common. In Japan in 1997, some 600 children were admitted suffering from vomiting, convulsions and respiratory problems after watching an episode of the animated series Pokemon . That episode recounted an explosion, followed by five seconds of bombardment of flashes. Seizures usually begin at five years and exacerbated during adolescence After the incident, the country decided to regulate emissions; later, by a similar event, would UK. These regulations also affect disco lights, but have not entered the gaming industry. And this is the second cause of this disease crisis. Something that has to do with the distance from the observed images. You play video games closer than watching TV and that encourages more of retina, says Parra. Therefore, experts recommend not watching television and playing video games not a short or dark rooms. And if they detect any signs of crisis must cover one eye, advises Parra, which calls for a European regulation that prevents harmful images to photosensitive spread. In Spain, nor has it been raised. There is not a regulatory agency, such as the UK, which receives complaints concerned; although it has not come to any self-control , which examines advertising agency. Some experts blame the underdiagnosis and ignorance. Vanessa recommendations of specialists is well known. However, what works is caution. I have to be very careful and avoid certain things. I can not, for example, go see movies in three dimensions [their movement and stimuli often affect people with this disease], he explains. I recently was able to finally take off driving license, but to do so requires a strong polarized glasses that reduce the light intensity of the flash to be found. He began to study business, left. His illness limited. Especially since I could not use computers before, with her green little letters. Now with the new, the picture looks different, so I start to drive, he explains.
