Dec. 24, 2009 Many brain training products claim to be able to keep us mentally fit. Some products even claim that brain training can prevent dementia in old age. But there is no scientific proof that games or other brain exercises can have this effect. That is what the German Institute for Quality and Efficiency in Health Care (IQWiG) has discovered.
Brain training can lead to an improvement, but only in the specific ability it is aimed at
As we get older our thinking gets slower and it is harder for us to learn new things. Many people try to stay mentally fit by, for example, learning a new language or doing crossword puzzles. Computer games that aim to keep the brain active are also becoming increasingly popular. "Doing exercises like trying to find symbols on a computer screen as fast as possible can actually improve your reaction time," explains Professor Peter Sawicki, the Institute's Director. "But scientific studies have shown that brain training only leads to an improvement in the specific ability that it is aimed at. So if you learn to find symbols quickly, it does not mean that you will be able to remember names better too."
There is no need for people to push themselves to do brain training if they do not enjoy it
Research has not shown that brain training can keep up or enhance people's overall mental abilities. "So there is no need to feel bad if you do not enjoy brain training: there are no health reasons for doing it," says Sawicki. "But if you think brain training exercises are fun, you can try out different things. For example, completing sequences of letters can improve your logic skills. And practising word association techniques can help you to remember things better."
