Bread and video gamesPosted: 11/08/2012
What do a loaf of bread and an action video game have in common? Both are man-made and widely consumed, yet hugely underrecognized as potentially serious health hazards. There are a lot more parallels.
Sensitivity to gluten, the primary protein in wheat, and to the bright flash and rapidly moving patterns game of screens, are both considerably more pervasive than the medical community and the general public had realized. Awareness of gluten sensitivity has grown tremendously in the past decade, though, because a portion of the medical community broadened its understanding of a disorder once defined by very rigid diagnostic criteria.
Consider this comparison:
Progress on the gluten front
For decades the only type of gluten sensitivity recognized by doctors was celiac disease, a severe condition that often, but not always, manifests with gastrointestinal problems. The only diagnostic testing required an intestinal biopsy that–turns out–is easily falsely negative. After a negative biopsy, would be told that celiac disease had been ruled out, and that therefore it was OK to eat wheat and other grains containing gluten. In actuality many of these patients either had celiac–but a misleading biopsy that didn’t collect tissue samples from the affected area of the intestine–or they had a different form of gluten sensitivity that causes damage only to other body organs, rather than the intestine.
Because doctors were taught in medical school that celiac disease is very rare, occurring in only one in several thousand individuals, there seemed to be little reason to consider the diagnosis in patients, order a biopsy, or question a negative biopsy result. Some researchers suggest that ten percent or more of the American public has a sensitivity to gluten, in most cases with no obvious symptoms or symptoms that don’t suggest a food sensitivity. Even without obvious symptoms gluten intolerance can be a very serious disorder that affects daily functioning and quality of life.
Growing numbers of consumers without an official diagnosis of gluten sensitivity are being more proactive by experimenting on their own with a gluten-free diet as a healthier way to eat. Many notice a range of improvements in their well-being from this change. A rapidly expanding market of prepared gluten-free foods makes a gluten-free lifestyle less burdensome. An increasing number of restaurants offer gluten-free menus, and new gluten-free foods are a booming market for food retailers. Celiac and gluten-free support groups provide practical and moral support. In addition to peer-reviewed research, there are now a lot of books for consumers and online resources. Probably most consumers are learning about gluten sensitivity from these sources rather than their clinicians, and some are helping educate their doctors about it.
The photosensitive epilepsy front
Because doctors were taught in medical school that photosensitive epilepsy is very rare, occurring in only one in several thousand individuals, there has seemed to be little reason to consider the diagnosis in patients, order an EEG with photic stimulation, or question a negative or inconclusive EEG. There is no practical, reliable way to know how prevalent photosensitive epilepsy is in the general population. Even without obvious symptoms of a seizure, people who experience subtle seizures can experience impairments that affect daily functioning and quality of life.
Without an official diagnosis of photosensitivity, consumers can experiment with a screen-reduced or screen-free lifestyle–should they have an inkling that subtle seizure activity caused by screen exposure is affecting their health. However, at this time there are few products or supports to help them cut back on recreational screen time. A limited number of mental health providers offer therapy for Internet or video game addiction. Most focus on treating the addiction itself rather than on overcoming the physical and mental health consequences of exposure to potentially seizure-causing screens. Consumers are still essentially on their own to figure out the connection between video games and seizure activity, and there is little for them to read on the subject. Little research is being carried out in the US on photosensitivity and today’s electronic entertainment.
Perhaps there is reason to be encouraged by the progress in educating the public and clinicians about gluten-related health problems. In the face of similar obstacles to wider awareness and prevention, it should be possible for seizures induced by visually overstimulating electronic media to become better known, understood, and prevented. In the interim, a great deal of work lies ahead to empower consumers with the information they deserve about screen-induced seizures. Please help spread the word.
