Review: Dakim BrainFitness System

October 29, 2009 Brain Fitness, Cognitive Training, Memory, Mental agility, Software Review 3 Comments

The folks at the Dakim BrainFitness System were kind enough to send a unit to me to use for a few days so that I could review their program. In the weeks since I sent it back to them, I’ve had some time to think about the program and I’m happy to say that it’s an excellent alternative to other computer-based brain fitness training programs.

Unlike most other programs, the Dakim System isn’t a software package that you have to install on your own computer. It arrives in a box, complete with a computer that’s already set up with the program. All you have to do is open up the box and plug in the computer.

And the computer that comes with the system is the most user-friendly machine I’ve ever seen. The initial set up is explained to you by the computer over speakers that are built in to the unit. And you don’t have to use a keyboard or a mouse to use the system. You just touch the screen to answer questions as the computer is set up. That’s also how you interact with the computer when you start the training program.

The training program includes a nice variety of tasks that tap attention, memory, and problem solving. The tasks use materials that are likely to be familiar to users over 50, such as movie clips from old films, and change quickly enough to keep you from getting bored. The unit can be connected to the Internet to get updated materials, so you will be able to use the System for a long time to come. The new material requires that you pay a monthly subscription, though, so that’s an extra cost of the system.

The program has multiple levels of difficulty, so you will be able to make steady progress as you work with it. The program is just right for many users over 50, but doesn’t include tasks that focus on working memory (remembering more than one thing at a time and then thinking about them) and it’s not clear to me how well it will help you develop processing speed (how fast you can take things in and make decisions about them).  Other programs include these tasks, but in our experience they may be too difficult for many users. The Dakim System is likely to be accessible to almost every user.

Overall, then, the Dakim BrainFitness System is probably best suited for people who don’t already have a computer and don’t already know how to use a mouse and keyboard. The touch screen format makes the unit very easy to set up and use. The program content will give users a regular mental work out that will help them keep their brains working. I give the Dakim BrainFitness System an A+ for usability. The program content will help users keep the minds active, and will help you track your progress.

Update at 2:15 PM:The folks at Dakim point out to me that several of the subtests do, in fact, help train working memory. I stand corrected.  They also let me know that they’re working on a speed of processing task for inclusion in a future update.

Posit Science Program Effective in Study

Positive Science’s brain fitness software is the subject of a paper in a recent issue of the Journal of the American Geriatrics Society. The paper presents results of the IMPACT study, a test of the effects of their software on elders’ cognitive functioning. The study is noteworthy for having been carried out at three sites by reputable scientists, and its design made it a genuine test of the effects of Posit’s program.

For those of you not familiar with Posit’s programs, they are based on key ideas developed by the company’s president Dr. Michael Merzenich. He has argued that it’s possible to change the functioning of the brain through targeted computer training, and the software focuses on key abilities such as the ability to detect rapidly-changing sounds and following lengthy sets of directions. Users of the software are encouraged to use it for about one hour a day, five days a week, for eight weeks.

One of the best things about this study is the control group used by the investigators. People in the control group (the one compared) were asked to do cognitive stimulation activities that are similar to those many people believe might be helpful — viewing an educational video and answering questions about it.

The IMPACT study showed that people who completed the computer-based training did better on outcome measures than the people in the control group. These outcome measures were neuropsychological measures in a battery given to participants both before and after they either used the program or were in the control group.

Statistical analyses showed that people who used the computer program scored better on these measures than the people in the control group. The authors conclude that the program may be helpful.

The differences between the groups were statistically significant, and that’s important for all of us to know. But it’s also important to look at how big the effect of using the program was. One measure, the Auditory Verbal Learning Test or AVLT, showed a significant difference. The AVLT asks someone to remember a list of 15 words. In this study, the people who used the computer program remembered, on average, about six tenths of a word more after using it.

This doesn’t mean the program isn’t useful. This amount of improvement is similar to that seen with some prescription medications used for Alzheimer’s disease, for example, and some people may have done much better than the average. It also doesn’t tell us how much change would occur for people who use the program over longer periods, too. But it seems to me that most people would want a clear idea of how well the program works before investing in it.

Changes in Brain Size with Aging

Understanding brain aging has to be research priority. The average age of people in the US is increasing. This means that there are more older people at risk for diseases that occur as people get older, such as Alzheimer’s. In people, the size of the brain decreases as they get …

Exercise, Mitochondrial DNA, and Brain Fitness

One very influential theory of why our physical and mental functions decline with age holds that changes in our DNA accumulate over time so that out cells don’t work any more. Perhaps the most important part of our DNA exists in every cell in a special part called the mitochondia. …

The Default Mode Network and Brain Fitness

If brain fitness is more than just trying to avoid memory loss as you get older (and I think it is), then understanding how you think is (I think) critical. Sometimes called metacognition, this means not just thinking, but thinking about thinking. Follow that? Metacognition is the idea that we …

Mindfulness Meditation, Brain Fitness, and Gray Matter

Most people know that the brain is smaller with age, at least in part due to loss of brain cells in parts of the brain related to perception, memory, and executive processes. Anything that can slow down or reverse the process should be of interest to all of us, whatever our age. …
