Playing too many video games may soon lead to a mental health disorder diagnosis.

The World Health Organization included agaming disorder in its draft of new diseases to prepare for in 2018.

The disorder is defined as an ongoing and persistent habit of "sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning, according to a new beta draft of the 11th International Classification of Disease.

The disorder includes impaired control over gaming, increasing priority given to gaming to the extent that gaming takes precedence over other life interests and daily activities and continuation or escalation of gaming despite the occurrence of negative consequences.

The draft guidance said video game playing must be evident for at least 12 months.

Health care professionals can diagnose people who play for a shorter amount of time if the conditions are severe.

Gregory Hartl, a spokesman for the WHO, told CNN that the new entry on a gaming disorder "includes only a clinical description and not prevention and treatment options."

Hartl said health professionals use the draft of diseases to diagnose conditions.

Dr. Chris Ferguson told gaming news website Kotaku that he has considerable concerns about this proposed diagnosis.

He said many researchers are comparing gaming addiction to heroin or cocaine addiction, which is a mistake.

There are many myths such as that games involve dopamine and brain regions similar to substance abuse, Ferguson said. Theres a kernel of truth to that but only insofar as any pleasurable activity activates these regions. How gaming involves them is more similar to other fun activities like eating chocolate, having sex, getting a good grade, etc., not heroin or cocaine.

Similarly, University of Oxford psychologist Andrew Przybylski said its a bad idea to identify gaming an addiction.

The diagnosis risks stigmatizing millions of players and may divert limited mental health resources from core psychiatric problems such as depression or anxiety which might be at the heart of problematic play, he told Kotaku.

The debate has existed for years about whether or not video games have positive benefits. Back in 2015, experts wondered if video games could help children manage medical issues like attention deficit hyperactivity disorder, depression and autism, according to the Deseret News.

Earlier this month, a study from researchers at the University of Montreal found that video games can keep elderly brains sharp. People age 55 to 75 were asked to either play piano or play Super Mario 64 for 30 minutes a day for five or more days a week.

Playing video games appears to be awesome for an older persons hippocampus, an area of the brain which is particularly important to our memory functions, according to Uproxx.

Matt Omernick, executive creative director of Akili, a startup thats developing a video game that aimed to help children with mental health disorders., told NPR in 2015 that video games have the ability to improve cognitive skills.

"The qualities of a good video game, things that hook you, what makes the brain snap, engage and go, could be a perfect vessel for actually delivering medicine," he said.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
