There are tons of researchers debating whether or not brain games and mental exercises such as KenKen and Sudoku can actually help the brain develop, and thus “beat” Alzheimers. A study done at East Carolina University studied the effects of daily casual mentally challenging video games. The results were promising. As opposed to video games that require little logic and reasoning, games such as Bejeweled, a simple logic game, helps the brain promote active participation. This type of participation cannot be found in activities such as watching TV or playing a mindless video game.
The brain needs exercise just like the body does. If you use and challenge your brain often, it will be healthier for longer. Pretty simple huh?
