There's a first-of-its-kind study taking place at Ohio State University in Columbus, looking at the impact of frequent video gaming.
A new study shows that more than 150 million Americans play these games. 60 percent of those do every day.
Now researchers at OSU are doing stress tests on e-sport athletes to find out how the games impact them.
Psychologists say that games can cause anxiety, and can lead to depression for those who just can't seem to turn those games off.
But they also get higher cognitive ability, and can dual-task more then the general population.
