Computer Software for Brain Fitness

A lot of advertising today touts computer software for brain fitness or brain training activities. Some of the software is (relatively) inexpensive, and some costs a fair amount (for example, about $400 for one program). Several websites offer memberships that give you access to stimulating games and other training activities.

How do you decide what software you should use?

First, I think it’s important to remember that nothing has been shown to stop cognitive aging or to prevent Alzheimer’s disease. Brain fitness, a brain gym, or any other cognitive fitness program may help you maintain your current level of function and may improve some specific skills, such as memory and thinking speed. These are important benefits and make brain fitness programs worth considering.

As for the software, as with many things, it depends. Some software programs have been subjected to more rigorous testing than have others. On the other hand, most brain fitness software programs have similar content. They often include activities that try to help you improve your working memory, your ability to think and react quickly, and your capacity to do several things at once. Some software programs have very original ways to improving your ability to do things. Posit Science’s new offering, Cortext, now includes a software program that helps you improve your visual attention to the world around. This program was developed by Dr. Karlene Ball at the University of Alabama, and has been shown to improve older driver’s skills. It’s called the Useful Field of View, or UFOV.

Some activities built in computer brain training software and often used in brain gyms are pretty much the same whether you’re using an inexpensive handheld trainer. Others, like the UFOV, are only available in a specific package. So whether one program or another is best for you may depend on what kind of memory or other cognitive problems you are having trouble with, and what you want to improve.

A recent article in the International Herald Tribune describes some of the available software programs, and some creative ways that some older adults are figuring out how to maintain their function. The author of the article quotes Dr. Gene Cohen, Director of the Center on Aging at George Washington University, who says that what’s essential is some activity to “challenge your brain.” (Click here to see the article.)

One man, for example, reads books upside down to improve his cognitive flexibility. Another man takes opportunities to memorize numbers he sees around him. The author quotes one of the persons in this article as saying “Smart people find new ways to exercise their brains that don’t involve buying software or taking expensive workshops.”

I would say there are three important issues in deciding whether you use brain fitness software or go to a brain gym.

• The first is whether you want an evaluation of your strengths and weaknesses to help you guide your work in the brain gym. A comprehensive assessment also will give you a baseline to help determine whether any of your abilities change over time.
• The second issue is whether you want to benefit from a specific training activity that is only available in a specific software package. Some people think doing the brain puzzles of Sudoku (a game that asks to do mental arithmetic across several parts of a puzzle) is helpful. You can do that in books you can buy at the grocery store, or you can do it in an inexpensive handheld gaming device such as the Nintendo DS. On the other hand, if you want to work on certain visual or auditory skills, some of the software programs may be a better bet.
• The third issue is whether you want the help, encouragement, and support you can get from the staff in a brain fitness program. Just as many people do well in working out in a gym they have in their home, others find that actually going to a health club helps them stick with their program. This may be especially true if you have a personal trainer or are in a group.

Computer Training and Memory Problems

It’s a really “hot” topic, and an often-discussed topic: Can cognitive training on computer software help you improve your memory and stave off Alzheimer’s?

I think the answer to the first question may turn out to be at least a partial yes. I think it’s pretty clear that computer-based training can improve your memory. A lot of research has shown that older people can learn new things, just as younger people do. Sometimes the way older people who are taught may have to change, and sometimes older people need a little more help, but older people can learn new things. My colleague, Dr. Sara Czaja at the Center on Aging here at the University of Miami, has shown that older adults can learn how to do diverse jobs such as entering data on a computer or working with a computer to answer customers’ questions about their insurance policies. Another colleague in the Center, Dr. David Loewenstein, has also shown that even people with memory problems can improve their memory.

A large, multi-center (done at several different locations) trial sponsored by the National Institute on Aging showed that certain kinds of cognitive training had significant effects  on reasoning, memory, and psychomotor speed. Perhaps most exciting was the demonstration that some of these training effects were still evident after five years. More recently, several of the companies who sell cognitive or brain fitness software for brain gyms have shown that people who use the software may show improvements in memory and other abilities. I think it’s pretty safe to conclude that older adults can benefit from cognitive training.

Will doing the training keep you from getting Alzheimer’s disease, or from getting memory problems if you don’t already have them? That’s really a good question, but as in many cases, there isn’t a very good answer. Just as cognitive reserve (see my post from April 25 for more about cognitive reserve: click here) may mean it takes longer for someone to have recognizable memory problems, cognitive training may work in much the same way. We know that a lot of the people who participate in cognitive training activities feel that they are helpful.

I think computer-based cognitive training may be very useful in helping participants feel that they understand how their mind works and better able to cope with daily challenges to remember things and solve problems. And as far as we know, there are few or no side effects of computer-based training.
