How old you feel makes a difference in how you think your brain is working, especially for women. And once again, mood and self-efficacy make a difference for everyone in what they think is going on with their brains.
When I’ve spoken to groups about brain fitness, I always mention the importance of stress and mood for brain fitness. Something many people don’t realize is how insidious stress can be. When stress is chronic, we get used to it and don’t notice it. It still has its effects.
Stress can affect your memory and other abilities in a number of ways. Psychological stress increases levels of hormones in your body that are known to be toxic to your brain. Chronic stress may cause depression, and depression by itself can affect your memory and your ability to think rapidly and clearly.
How can you tell whether you’re under significant stress? There are a number of stress scales on the Internet. I think the best way is to ask yourself two questions: (1) How often do you feel your ability to cope with things is challenged? and (2) How successful are you at coping with these challenges? The answer to how stressed you are comes from your response to both of these questions. If you feel frequently stressed, but you feel as though you’re doing a pretty good job of coping, your stress level is likely moderate. If you are frequently stressed and feel as though you are just barely hanging on, your stress level is probably much higher.
Coping with stress requires you to recognize that you’re feeling stressed. What causes you stress?
- Can you do anything about it?
- Can you avoid it?
- Try to schedule stressors for the time of day you’re most energetic and able to cope.
- At some point in the day, stop for five minutes and pay attention to your breathing. Interrupt the daily plunge into activity by taking five minutes for yourself.
Take stress seriously, dead seriously. Have a management plan that includes scheduling, exercise, and some form of relaxation.
With all the uncertainty in the economy, more and more people are asking about how to manage anxiety. Although several types of medications can be helpful in coping with anxiety, some of them (drugs in the group of benzodiazepines, such as Valium, Xanax, and Ativan) can actually have a negative impact on your memory. Other patients whom I see simply don’t want to take medicines for their anxiety. Since anxiety and stress can make your memory worse, managing your anxiety should be near the top of your brain fitness list.
Top ways to manage anxiety without medications:
Find out what you’re anxious about, and do something about it. Many patients have vague anxiety and aren’t quite sure what it’s about. See if you can figure it out. Talk to a friend about how you feel. Sometimes just talking about a problem can help make it clear. Another person’s viewpoint may help you to see a problem in another light.
Exercise. Both aerobic (walking, running, bicycling, swimming) and nonaerobic (weight training) can help you manage anxiety. People usually feel less anxious after exercising. If you aren’t exercising now, check with your doctor to make sure it’s OK to start. Even 10-15 minutes a day of walking can make a difference.
Relax and breathe. Researchers long ago noticed that it’s almost impossible to breathe deeply and feel anxious at the same time. Take 10 minutes twice a day to sit quietly, relax the muscles in your neck and back, and breathe fully. If you do this for a week you’ll feel better.
Meditate. Researchers have shown that almost any kind of meditation improves anxiety. I believe that meditation that helps you develop attentional focus will not only relieve stress and anxiety but also improve your memory. Mindfulness meditation is one form of meditation that is very helpful.
Distract yourself. Sometimes you can’t solve a problem but just have to live with it. Even after you exercise and meditate, you may still have to confront a problem over which you have little control. Try to find things that you enjoy doing that can help give you a break from feelilng anxious. Hobbies can often help people distract themselves. Doing something that is intellectually challenging is also good for your brain health.
Several weeks ago, I had the opportunity to talk about brain fitness at a meeting of the Miami Rotary. After my talk, there were lots of questions. Several of the questions had to do with sleep and brain fitness. All of the questions seemed pretty good, so I thought I would answer them here in case other folks are interested. The first question is about sleep and brain fitness.
How we sleep changes as we get older. Many people over 50 feel as though that they don’t sleep as well as they used to. Their perception is supported by research evidence. Studies of sleep and aging show that how people sleep change as people get older. The normal cycles of light sleep, deep sleep, and rapid-eye movement (REM) sleep don’t occur in the same way. Deep sleep is often associated with feeling rested when you get up in the morning, and studies show that older people may not get as much deep sleep. It may take you longer to get asleep, and you may wake up more often during the night.
Older adults may get sleepy earlier and take more naps during the day. It’s not unusual for me to see people who complain about waking up too early in the morning. When I ask about their sleep, though, I find out that they go to bed at 9:00 PM and wake up at 3:00 AM. It’s true that’s a little early – but often these folks take a two-hour nap in the afternoon. They get eight hours of sleep, but it’s distributed in a different way. Although it’s sometimes hard to stop taking naps entirely, it’s often helpful to try to keep them to a minimum. If you sleep a lot during the day, you may not sleep very well at night.
So what about brain fitness and sleep? Study after study has shown that sleep deprivation affects your mental abilities and mood. So if you feel as though you can’t concentrate or work as well as you’d like after you don’t get enough sleep, it’s probably true. This may be especially true for tasks that require attention for a long time. Some of those kinds of tasks are harder for older adults to begin with, and may be even harder if you don’t sleep. Don’t think that you can’t function at all if you don’t sleep well – you’ll usually be able to function. But odds are you won’t function as well as you would like.
An interesting article appeared in the New York Times over the weekend. The article by Katie Hafner is titled “Exercise Your Brain or Else You’ll . . .Uh . . .” You can find the original article here (registration is required, but is free).
The article recounts several incidents in which people over 50 had troubling memory problems. One man, for example, couldn’t remember his own address when he went to send a package, and a woman who couldn’t locate her cell phone later found it in the refrigerator. Do these kinds of memory lapses mean that these persons have serious memory problems? The answer is, “It depends.” One memory lapse doesn’t mean very much. But a pattern of memory problems over a period to time may mean that someone’s memory isn’t as good as it used to be. Even if that’s true, though, it doesn’t necessarily mean that a person has a serious brain illness such as Alzheimer’s disease. Only a complete evaluation by a well-trained clinician can make that decision.
One issue the article highlights is how people over 50 or so may be more concerned than younger people about memory lapses. Put simply, people over 50 are more likely to worry about brain fitness. I have the pleasure of working with several young people in the Center on Aging. I notice that they may have memory lapses, but they don’t worry about them nearly as much as some of the people who come to our Memory Disorders Clinic for evaluation of their memory. They’re young, and if they forget something they don’t automatically worry about it. For them, it’s just a lapse. For someone over 50, the same kind of lapse is ground for worry. I’m not suggesting that if you’re over 50 and you’re worried (or your spouse and family are worried) about your memory you shouldn’t do something about it. I am suggesting that people over 50 may worry more about their memories. The New York Times article goes on to talk about how worry about cognitive fitness and cognitive decline or memory problems is feeding interest in brain fitness software.
If you’re worried about your memory, the best thing to do is find a qualified clinician who can complete a screening evaluation. Tests of memory and other cognitive abilities can help you find out where you stand in relation to other persons who are similar to you. This can help you decide whether your memory problem needs to be treated. And if you have a memory problem, a knowledgeable clinician may help you find out what’s causing it. Some memory problems are caused by problems such as mood problems, stress, or other treatable conditions. Getting the treatment you need may help.

I saw an interesting blog post yesterday evening on the site of the Huffington Post about the potential benefits of meditation – or at least about what one woman thinks might be the benefits. (more…)
Although many people are excited about the potential for using computers to train their brains, we shouldn’t forget that other techniques have been used to the train the brain for many centuries. I’m thinking about the large number of techniques for meditation. While free computer software still requires an investment in a computer, meditation only asks you to sit or lie quietly and focus your mind.
A recently-published study shows parts of the brain in long-term meditators are larger than the same parts of the brain in people who don’t meditate. The article by Eileen Luders and her colleagues appeared in a recent issue of the journal Neuroimage (Vol. 45, No. 3, pp. 672-678, April 15, 2009). The study showed that portions of the orbitofrontal cortex and the hippocampus were larger in persons who had been regular meditators for 5 or more years. The study is interesting because the parts of the brain that were larger are often thought to be important in helping people keep themselves emotionally balanced.
A number of strategies are likely to be helpful for meditators. There has been a great deal of interest over the last several years in mindfulness meditation. Researchers have studied how it can be used in reducing anxiety and depression. Mindfulness is based on Buddhist meditation (for a brief article, click here) but you don’t have to be a Buddhist to practice meditation. In fact, one of the most important persons who has promoted mindfulness is Jon Kabat-Zinn, a researcher at the University of Massachusetts. You can see a video presentation by him on YouTube by clicking here.
