While many parents believe most video and computer games are mindless, there exists one game that has proven to make minds three years younger after just ten hours of playing. The effects also last at least a year.
Scientist have created a game that trains the brain to remember information while filtering out distractions.
It was tested on men and women over the age of 50. They played "Road Tour" for ten hours and proved to have younger minds a year later.
Overall, their brains were three years younger, but a test that measured speed and attention revealed their brains were almost seven years younger.
Professor Fred Wolinsky, who does not have any financial stake in the game, said the tests revealed "remarkable" results.
"We know that this can stop the decline and actually restore cognitive processing speed to some people. So, if we know that, shouldn't we be helping people? It's fairly easy and older folks can go get the game and play it," he said.
One must pay a fee to play the game online. It involves remembering two things, a vehicle and a road sign. They are asked later in the game to identify the car and the position of the road sign.
As time goes on, it gets harder, with more distractions and less time.
It is supposed to improve a number of skills, including processing speed, memory, peripheral vision and attention.
"These functions are critically important in every day life," Wolinsky said.
He also found that the game was "far more effective" than crosswords, and playing it at home was just as good as playing it in the lab.
Playing it for ten hours made the mind three years quicker, while 14 hours made it four years quicker.
But some people have argued the effectiveness of brain training games, and have questioned if it really does help us in our every day lives.
Dr. Doug Brown, director of research at the Alzheimer's Society, said, "Many of us enjoy puzzling over a game. However, there is currently little evidence that brain training has any cognitive benefits."
"Although there is no cure for dementia, research has consistently shown that eating a balanced diet, exercising regularly and not smoking can make an important contribution to reducing your risk of developing dementia."
