I have learned that video games help people with severe chronic pain. Has something to do with pheromones and of course concentration. I am sure World of Warcraft has helped me improve Seriously, yes I do. I am also in the market for software for the 2-year old crowd.
Definitely I know of many studies where games are used to "redirect" someone's attention. So if someone is undergoing therapy that makes them really hot for example, they give them a video game that's all set in arctic cold and it really does help them Very cool!
I believe that even little games like card games can do that. Also coloring may help the brain too. Probably everything that uses the brain actually helps it. All you need to do is think and try to solve something and it probably helps.
