July 17, 2014 July 17, 2014 Two ways to stay mentally sharp Regular physical activity helps keep your heart, lungs, and muscles in shape and can stave off the effects of aging. In much the same way, exercising your brain can help keep your mind sharp and your memory intact. Here are two ways to activate your brain. Keep busy and engaged The MacArthur Foundation Study on Successful Aging, a long-term study of aging in America, found that education level was the strongest predictor of mental capacity as people aged. The more education, the more likely an individual was to maintain his or her memory and thinking skills. Other research has shown that people who held jobs that involved complex work, such as speaking to, instructing, or negotiating with others, had a lower risk of memory loss (dementia) than people whose jobs were less intellectually demanding. It probably isn’t the years of formal education or the type of occupation itself that benefits memory. Intellectual enrichment and learning stimulate the brain to make more connections. The more connections, the more resilient the brain. That’s how a habit of learning and engaging in mentally challenging activities — like learning a new language or craft — can help keep the brain in shape. Get your copy of Improving Memory By age 60, more than half of adults have concerns about their memory. However, minor memory lapses that occur with age are not usually signs of a serious problem, such as Alzheimer’s disease, but rather the result of normal changes in the structure and function of the brain. This report describes these normal age-related changes and other, more serious causes of memory loss — and how to distinguish between them. Stay connected Establishing and maintaining close ties with others is another way to maintain mental skills and memory. There are several ways that social engagement may do this. Social interaction and mentally engaging activities often go hand in hand (think volunteering or tutoring schoolkids). Social relationships can also provide support during stressful times, reducing the damaging effects that stress can have on the brain. Social support can come from relationships with family members, friends, relatives, or caregivers, as well as from a religious community or other organized group. Meaningful, socially engaging activities may prove especially helpful. In a study conducted with the Baltimore Experience Corps, volunteers were assigned to either a waitlist (control group) or a group that helped elementary school children during class and library time. Early results suggested that participants who remained engaged in the program for many months improved their executive function and memory.

The U.S. Food and Drug Administration has recently proposed changes to make the labels even more useful. Use everyday habits to keep your memory in good shape Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline. Exercise Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise “dose” of exercise isn’t known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high impact aerobic dancing, square dancing, and tennis. Exercise helps memory in several ways. It reduces the risk of developing several potentially memory-robbing conditions like high blood pressure, diabetes, and stroke. Exercise is good for the lungs, and people who have good lung function send more oxygen to their brains. There is some evidence that exercise helps build new connections between brain cells and improves communication between them. Finally, exercise has been linked to increased production of neurotrophins, substances that nourish brain cells and help protect them against damage from stroke and other injuries. Here are some ways to build physical activity into your daily routine: Walk instead of driving when possible. Set aside time each day for exercise. For extra motivation, ask your spouse or a friend to join you. Use the stairs instead of the elevator. Plant a garden and tend it. Take an exercise class or join a health club. Swim regularly, if you have access to a pool or beach. Learn a sport that requires modest physical exertion, such as tennis. Go Mediterranean Mediterranean-type diets highlight whole grains, fruits and vegetables, and healthy fats from fish, nuts, and healthy oils. This eating style helps promote heart health and may also lessen the risk of memory and thinking problems later in life. In a study that followed more than 2,000 people over four years, those who most closely followed a Mediterranean-type diet had a lower risk of developing Alzheimer’s disease. A later study suggested that following a Mediterranean-type diet could slow the conversion of mild cognitive impairment into full-blown dementia. The types of fat that predominate in the diet also seem to affect memory. As part of the national Women’s Health Initiative, 482 women ages 60 and older were observed for three years. They reported on their diets, and researchers tested their memory and thinking skills at the beginning of the study and at the end. Those who ate more unsaturated fat (which is abundant in vegetable oils and fatty fish) and less saturated fat (from red meat and full-fat dairy foods) had significantly less decline in memory than those who ate relatively little unsaturated fat. Eating several servings of fruits and vegetables can also protect memory. Foods from plants are chock full of vitamins, minerals, and other nutrients that may protect against age-related deterioration throughout the body.
