SEVEN WAYS TO MAKE YOUR BRAIN SMARTER...
Here's a very interesting article ... How many of these things are a part of your life?
MIND GAMES … SEVEN WAYS TO MAKE YOUR BRAIN BETTER, FASTER, SMARTER ...
by William Speed Weed, Reader’s Digest, August 2006
# 1. MOVE IT … “The best advice I can give to keep your brain healthy and young is aerobic exercise,” says Donald Stuss, PhD, a neuropsychologist and director of the Rotman Research Institute at Baycrest Centre for Geriatric Care in Toronto.
Mark McDaniel, PhD, professor of psychology at Washington University in St. Louis, agrees, but adds, “I would suggest a combined program of aerobics and weight training. Studies show the best outcomes for those engaged in both types of exercise.”
As we age, our brain cells, called neurons, lose the tree-branch-like connections between them. These connections, or synapses, are essential to thought. Quite literally, over time, our brains lose their strength. Perhaps the most striking brain research today is the strong evidence we now have that “exercise may forestall some kinds of mental decline.” It may even restore memory. Myriad animal studies have shown that, among other brain benefits, aerobic exercise increases capillary development in the brain, meaning more blood supply, more nutrients and – a big requirement for brain health – more oxygen.
#2. FEED IT … Another path to a better brain is through your stomach. We’ve all heard about antioxidants as cancer fighters. Eating foods that contain these molecules, which neutralize harmful free radicals, may be especially good for your brain too. Free radicals break down the neurons in our brains. Many colorful fruits and vegetables are packed with antioxidants, as are some beans, whole grains, nuts and spices.
More important, thought, is overall nutrition. In concert with a good workout routine, you should eat right to avoid the diseases that modern flesh is heir to. High blood pressure, diabetes, obesity and high cholesterol all make life tough on your brain, says Carol Greenwood, PhD, a geriatric research scientist at the University of Toronto.
If your diet is heavy, then you’re probably also heavy. The same weight that burdens your legs on the stairs also burdens your brain for the witty reply or quick problem solving. The best things you can eat for your body, are also the best things you can eat for your brain. Your brain is in your body, after all. Greenwood’s recommendation is to follow the dietary guidelines from the American Diabetes Association (available at diabetes.org).
#3. SPEED IT UP … Our brains naturally start slowing down at the cruelly young age of 30. It used to be thought that this couldn’t be helped, but a lot of new studies show that people of any age can train their brains to be faster and, and in effect, younger. “Your brain is a learning machine,” says Michael Merzenich, PhD, a neuroscientist at the University of California, San Francisco. Given the right tools, we can train our brains to act like they did when we were younger. All that’s required is dedicated practice: exercises for the mind.
Merzenich has developed a computer-based training regimen to speed up how the brain processes information (positscience.com). Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to improve both speed and accuracy. Over the course of your training, the program starts asking you to distinguish sounds (between “dog” and “bog,” for instance) at an increasingly faster rate. It’s a bit like a tennis instructor shooting balls at you faster and faster over the course of the summer to keep you challenged. Though you may have started out slow, by the end of summer you’re pretty fast.
Similarly, Nintendo was inspired by the research of a Japanese doctor to develop a handheld game called Brain Age: Train Your Brain in Minutes a Day, which has sold more than two million copies in Japan. No software out there has yet been approved by the FDA as a treatment for cognitive impairment, but an increasing number of reputable scientific studies suggest that programs like Merzenich’s could help slow down typical brain aging, or even treat dementia. The biggest findings in brain research in the last ten years is that the brain at any age is highly adaptable, or “plastic,” as neurologists put it. If you ask your brain to learn, it will learn. And it may speed up in the process.
To keep your brain young and supple, you can do one of a million new activities that challenge and excite you: playing Ping-Pong or contract bridge, doing jigsaw puzzles, learning a new language or the tango, taking music lessons, building a kit airplane, mastering bonsai technique or another skill, and even relearning differential calculus.
“Anything that closely engages your focus and is strongly rewarding,” says Merzenich, will kick your brain into learning mode and necessarily notch it up. Merzenich, 64 years of age, has “4,000 hobbies,” including a wood shop and a vineyard.
#4 STAY CALM … While challenging your brain is very important, remaining calm is equally so. In a paper on the brain and stress, Jeansok Kim of the University of Washington asserts, in no uncertain terms, that traumatic stress is bad for your brain cells. Stress can “disturb cognitive processes such as learning and memory, and consequently limit the quality of human life,” writes Kim.
One example is a part of the brain called the hippocampus, which is a primary locus of memory formation, but which can be seriously debilitated by chronic stress. Of course, physical exercise is always a great de-stressor, as are calmer activities like yoga and meditation. And when you line up your mental calisthenics (your Swahili and swing lessons), make sure you can stay loose and have fun.
#5 GIVE IT A REST … Perhaps the most extreme examples of the mental power of staying calm is the creative benefit of sleep. Next time you’re working on a complex problem, whether it be a calculus proof or choosing the right car for your family, it really pays to “sleep on it.”
Researchers at Harvard Medical School have looked at the conditions under which people come up with creative solutions. In a study involving math problems, they found that a good night’s rest doubled participants’ chances of finding a creative solution to the problems the next day. The sleeping brain, they theorize, is vastly capable of synthesizing complex information.
#6. LAUGH A LITTLE … Humor stimulates the parts of our brain that use the “feel good” chemical messenger dopamine. That puts laughter in the category of activities you want to do over and over again, such as eating chocolate or having sex. Laughter is pleasurable, perhaps even “addictive,” to the brain.
But can humor make us smarter? The jury is still out and more studies are needed, but the initial results are encouraging. Look for a feature on exciting new research about humor and intelligence in the September issue of Reader’s Digest. (I’ll post this information when I get it.)
#7. GET BETTER WITH AGE … You’ve heard about the wisdom and judgment of older people? Scientists are starting to understand how wisdom works on a neurological level.
When you are older, explains Merzenish, “you have recorded in your brain millions and millions of little social scenarios and facts” that you can call upon at any time. You are a much better synthesizer and integrator of that information.”
Older people are better at solving problems, because they have more mental information to draw upon than younger people do. That’s why those in their 50s and 60s are sage. They’re the ones we turn to for the best advice, the ones we want to run our companies and our country.
As Barry Gordon, a neurologist at The John Hopkins School of Medicine puts it, “It’s nice to know some things get better with age.”
MORE WAYS TO STAY SHARP:
· DON’T SMOKE … Smokers perform worse than nonsmokers in studies of memory and cognitive function. No one knows whether smoking directly impairs memory or is merely associated with memory loss because it causes illnesses that contribute to poorer brain function. In addition, smoking increases the risk for stroke and hypertension, two other causes of memory impairment. In any case, if you smoke, it pays to quit. Research shows that people who stop smoking have less mental decline than those who continue to smoke.
· DRINK IN MODERATION … Excessive consumption of alcohol is toxic to neurons and is the leading risk factor for Korsakoff’s syndrome, a disorder that causes sudden and irreversible memory loss. If you’re a heavy drinker, cutting back can prevent further memory loss and will usually lead to some recovery of damaged memory function. (Miss Becky suggests no drinking of alcohol, for several health reasons, which I’ll discuss in a future article.)
· BE SOCIAL … Close ties with others can improve the cognitive performance of older people, according to a MacArthur study on aging and other research. Social support can come from relationships with friends, relatives or caregivers. A Canadian study published in 2003 identified a lack of relationships with friends and family as a risk factor for cognitive decline. The study, which followed people over age 65 for four years, found that the probability of maintaining good cognitive function was highest among people who socialized often and had strong social ties; the probability of losing cognitive function was highest among people who had the least contact.
Social engagement often goes hand in hand with intellectually stimulating activities, which in turn promote good memory function. Social relationships can also help support you during stressful times, reducing the damaging effects that stress can have on the brain.
· WATCH YOUR HEAD … Head trauma often results in memory impairment, which is a risk factor for future development of dementia. You can prevent head injury by using the appropriate gear during high-speed activities and contact sports. Car accidents are by; far the most common cause of brain injury, and wearing seat belts greatly reduces the injury risk. Use a helmet when bicycling, riding on a motorcycle, in-line skating and skiing. And you can lower the risk of concussion by wearing a mouth guard, which deflects the force of a blow to the chin, during contact sports such as football, hockey, soccer, basketball, rugby and martial arts.
