Scientists say that all those hours spent playing a game may not be bad for your child's brain.

More than 9,800 US kids were followed by a new study in the journal Natur e. The scientists from European universities said that kids who play video games have more positive impact on their intelligence than kids who don't play video games.

After two years, gaming positively impacted intelligence, according to the study authors.

The researchers said that controlling for genetic and socio-economic factors was an important part of their study. The group said that previous studies on video games and intelligence may have conflicting results because the teams neglected to control for the same factors.

They claim in the paper that studies have not accounted for genetic effects and that intelligence, educational attainment, and other cognitive abilities are all highly heritable.

The study says kids in lower socio-economic status might have a less functional environment at home that TV provides an escape from, making them more likely to watch it. The same environment can cause learning issues that are unrelated to the cartoons they watch.

You can at least enjoy your favorite titles knowing that it might be better for your brain than the latest season of a show that has not been canceled yet.

There are more on genetic considerations.
