How Much Attention Do You Have for Brain Fitness?

To learn something new, and especially to change your behavior, you have to pay attention. That sounds simple, but it isn’t. You only have so much attention to use at any given moment, and for most of us a lot of things are competing for it.

Torkel Klingberg, a professor at the Karolinska Institute in Sweden, has written about the problem in a book titled The Overflowing Brain: Information Overload and the Limits of Working Memory. Klingberg documents the incredible demands that are made on our minds by modern life and points out that our brains evolved to handle fewer tasks that were probably less complex.

I think the solution to the problem having too much to pay attention to while not having enough attention to pay has two parts. Klingberg provides a nice introduction into the first strategy: increasing working memory through brain training. Klingberg as well as others have shown that working memory can be trained, and limited evidence suggests that the difference training makes can generalize to real-life tasks.

The second part of the strategy is developing better attention through practice in focused attention and in resisting distractions. We all have the experience of forgetting something important because our attention was drawn to something else. The ability to pay attention to an object that is important is a prerequisite to almost any achievement.

Computer training has been used to help people learn to function better under distracting conditions; it may be a helpful strategy in coping with multiple distractions.

Meditation is a widely used technique that can help you reduce stress, help you focus on what’s important, and resist being distracted by things that aren’t important. Simply spending a little time each day in a situation with minimal distractions can help you appreciate how much of the noise and distractions in your life arise from inside yourself. If you allow each to rise to your consciousness, you can decide which issues deserve attention and follow-up action, and which can be ignored.

The bottom line: Training working memory with computer-based tasks can help. Meditation can help you focus on what’s most important and use your limited resources effectively.

Eating for Brain Fitness

A lot has been written on the Web about eating for brain fitness. Almost anyone might want to know if one magic food can make your mind clear and keep your memory sharp. When it comes to eating, there are no magic bullets, but studies give us some direction.

First, you should know that no really good study has been shown that any food or diet can prevent memory problems. That being said, there are some basic dietary principles that make sense.

One of the most basic principles of eating for brain fitness is to eat so that you can maintain a healthy weight. Studies have shown that excess fat can produce inflammatory substances that have been associated cognitive decline.

Sticking with a diet that helps you avoid excessive weight gain can also help you avoid developing something called the metabolic syndrome. That’s a combination of things that are associated with risk for diabetes and other diseases. One of the facets of metabolic syndrome is having high levels of blood sugar. Your brain needs sugar to work, but paradoxically if you have high levels of sugar in your body a lot of the time, you can have low levels of it in your brain.

Eating a diet that is high in fruits and vegetables, rich in whole grains, and low in saturated fats may help you keep your brain sharp. In particular, the Mediterranean diet has been related to lower risk for Alzheimer’s disease and slower decline in people who already have it.

If there are specific foods that are good for brain fitness, it’s not clear. Colorful berries, though, are high in substances called antioxidants and may help preserve your brain function. Other foods that may have an impact include leafy green vegetables (full of B vitamins that are key to maintaining your brain’s function) and other colorful foods.

Research doesn’t really support that idea that any one food is a magic bullet for keeping your brain functioning at its best, in spite of what you may read on the Web. The truth is probably a little more complicated.

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 …
