Want to Slow Mental Decay? Play a Video Game

I bet this never gets to a stroke protocol. But I bet if we increased the cognitive abilities of stroke survivors their recoveries would be much better. Don't listen to me, I know nuthin.

There may be a way for older people to prevent natural aging of their minds, and it could be as simple as playing a video game.

---

That's according to a study from the University of Iowa, which found that elderly people who played just ten hours of a game priming their mental processing speed and skills delayed declines by as many as seven years in a range of cognitive skills.
"We know that we can stop this decline and actually restore cognitive processing speed to people," says Fredric Wolinsky, professor in the UI College of Public Health and lead author on the paper published May 1 in the journal PLOS One. "So, if we know that, shouldn't we be helping people? It's fairly easy, and older folks can go get the training game and play it."
