Brain training may enhance specific ability, but no scientific proof exists for overall mental fitness

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) pointed out in information published on informedhealthonline.org today.

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."

    The title of this post is factually incorrect.  The contect comes from the republishing of a press release based on an old review of one paper.  Even though the press release came out in December 2009, the article reviewed was published in 2008 ... since that time some ground-breaking research came out in the Journal of American Geriatrics that concluded, "The experimental program improved generalized measures of memory and attention more than an active control program."  You can read the abstract at www3.interscience.wiley.com/.../abstract

    Posit Science, where I am CEO and Dr. Mike Merzenich is Chief Science Officer, makes scientifically-validated and engaging software that can help you think faster, focus better and remember more.  Over 30 clinical studies from institutions like the Mayo Clinic and Johns Hopkins show that our technology can have a range of benefits from improved memory to lowered health care costs to improved driving safety. The IMPACT study used the Brain Fitness Program built by our team.  For more information and to try free exercises, please visit http://www.positscience.com/braingames
