What do you guys think of the various brain building games that are on the market? There are programs for the most game systems and PDAs. Some that come to mind include Brain Age for the Nintendo DS and Advanced Brain Trainer for Palm OS. If you don't happen to have a PDA or game system, there's a web based alternative called Lumosity. The games that it provides are supposed to help you improve your memory, attention, processing speed and cognitive control. I can sure use all the help I can get to improve my memory, so I have been playing the games this afternoon. Each game is fun and easy to play and doesn't take a lot of time. If you want to keep playing after the free trial ends, you can pay per month or per year. We'll see if I can tell any difference after the 7-day free trial ends.
