Today’s parents are usually good at monitoring the content of TV and video games, ensuring that children are not exposed to violence, sexuality, and other adult themes. However, in many households, children may spend hours each day watching TV and playing video games. There is solid evidence that too much TV and video games increase the likelihood of a child developing problems with attention. A good rule of thumb for TV/video game usage is less than 2 hours daily, the less the better.
Limiting time spent with TV and video games is especially important for very young children. According to Dimitri Christakis, MD, MPH, Director of the Child Health Institute and author of The Elephant in the Living Room: Make Television Work For Your Kids, children as young as a few months old are watching too much TV, and may be developing permanent attention problems. In an article on education.com, author Rose Garrett writes, “For every hour of television toddlers watch a day, they are ten percent more likely to develop attention problems at school,” according to Dr. Christakis.
What’s more, according to a recent study about children who watched who watched more than 2 hours of TV per week 40% more likely to have symptoms of ADHD in adolescence than children who watched less TV. The problem is the speed of the frames. Fast-paced electronic media seem to train children’s brains to attend only to faced-paced stimulation (e.g., the opposite of a teacher at a whiteboard).

I like this MSN Health article by Rich Maloof: It nicely summarizes medical research and recommendations about TV & ADHD.
