Most of us are concerned about staying sharp mentally. Mind games are designed to exercise your brain. There are mobile apps such as Luminosity and Fit Brains claim to boost cognitive ability and ward off mental decline.
Do they actually work?
David Linden a professor of neuroscience at the John Hopkins School of Medicine doesn't think so. He says "the effects are small and don't last very long."
So if the games don't work what does? Dr. Linden believes that the best way to maintain mental fitness is with physical exercise. "Walking 30 minutes a day has a greater effect than playing any brain game. Even moderate, low intensity exercise is five times more beneficial to cognitive tasks than playing brain games on your iPad" he says.
Research has shown that exercise increases the volume of the brain and elevate patters of activity. The effects are especially beneficial for middle aged people.
The bottom line is clear. Exercise your brain by exercising your body.
