Screen Time vs ADHD

There is an interesting article on the New York Times today about kids with Attention Deficit Disorder and the exposure to TV and video games. Here is a summary:

Even though ADHD kids may lack attention, they can spend hours very focused on TVs and computers. Actually, according to the study, a child’s ability to stay focused on a screen, though not anywhere else, is actually characteristic of attention deficit hyperactivity disorder. There are complex behavioral and neurological connections linking screens and attention, and many experts believe that these children do spend more time playing video games and watching television than their peers.

Unfortunately, the kind of concentration that children bring to video games and television is not the kind they need to thrive in school or elsewhere in real life, according to Dr. Christopher Lucas, associate professor of child psychiatryat New York University School of Medicine. “It’s not sustained attention in the absence of rewards,” he said. “It’s sustained attention with frequent intermittent rewards.”

The child may be playing for points accumulated, or levels achieved, but the brain’s reward may be the release of the neurotransmitter dopamine. Children with A.D.H.D. may find video games even more gratifying than other children do because their dopamine reward circuitry may be otherwise deficient.

In a nutshell, increased screen time may be a consequence of A.D.H.D., but some researchers fear it may be a cause, as well. Some studies have found that children who spend more time in front of the screen are more likely to develop attention problems later on.

In a 2010 study in the journal Pediatrics, viewing more television and playing more video games were associated with subsequent attention problems in both schoolchildren and college undergraduates.

The stimulation that video games provide “is really about the pacing, how fast the scene changes per minute,” said Dr. Dimitri Christakis , a pediatrician at the University of Washington School of Medicine who studies children and media. If a child’s brain gets habituated to that pace and to the extreme alertness needed to keep responding and winning, he said, the child ultimately may “find the realities of the world underwhelming, understimulating.”

Children whose brains need neurochemical rewards seek out an activity that provides it. Children with social problems spend more time alone, facing a screen. Children struggling in the classroom develop mastery in a virtual world. I talk to parents of children with A.D.H.D. about basic dos and don’ts: No screens in the child’s bedroom. Pay attention to the content of the games, especially to violence. Set limits on screen time, and look for other ways to manage family interactions.
