Study: Video-game playing teens' brains similar to those of addicts

The brains of teens who play a lot of video games have larger so-called reward centers which make them look similar to the brains of addicts, according to a European study in the journal Transitional Psychiatry.

This suggests they get more out of gaming than people who play less.

Researchers are not able to say if the structural differences were due to excessive playing time or if some teens play a lot because their brains were enlarged in the first place.

The average weekly usage in the experiment was around 12 hours a week.

There is ongoing debate whether excessive gaming should be recognized as an addiction.
