Science-Based Medicine » Train Your Brain.
Although not addressed by this study, it is also common for companies to specifically claim that their brain-training exercises alter the brain waves. This is just an added layer of pseudoscience used for marketing. Any company that claims they can improve your brain waves is engaging in pure quackery. Some companies even claim to do this passively, just by listening to their tapes, for example. This would actually be counter productive, as it is active participation in any mental activity that seems to be important for improving mental function.
The market for brain training products this year is estimated at $225 million. This is not all necessarily waste - many may find Brain Age or other such games to be fun in their own right. Just don’t buy the hype.
