Computer games are being touted as a way to keep the body fit. Can they do the same for your brain? Most experts say “Not so fast.” As described in Improving Memory: Understanding age-related memory loss, a new Special Health Report from Harvard Medical School, people who play these games might get better at the tasks they practice while playing, but the games don’t seem to improve users’ overall brain skills, such as attention, memory, use of language, and ability to navigate. To stretch and exercise your brain, choose an activity you enjoy—reading, playing cards, or doing crossword puzzles are some good examples. If you’re feeling ambitious, try learning to speak a new language or play a musical instrument. Most of these activities come at a much lower cost than brain-training programs, and you’ll probably find them to be a lot more enjoyable, too.

Warren Buffett may be the second richest man in America, but he appears to be getting the poorest medical advice. Buffett announced to Berkshire Hathaway shareholders last week that he has early stage prostate cancer that “is not remotely life-threatening or even debilitating in any meaningful way.” If Buffett’s cancer had been detected because he […]

The hemoglobin A1c reading is an important number for people with diabetes. It’s a measure of the average blood sugar level over the preceding three months. For years, the American Diabetes Association recommended that almost everyone with type 2 diabetes should aim for an HbA1c level less than 7%. Keeping blood sugar as low as possible, called “tight control,” was thought to limit the havoc caused by diabetes. New guidelines from the American Diabetes Association (ADA) and European Association for the Study of Diabetes recommend taking a more “patient-centered approach.” For people who are newly diagnosed with type 2 diabetes but who are otherwise in good health, the ADA still suggests aiming for an HbA1C of 6.0% to 6.5%. For people who have had diabetes for a while, an HbA1c goal of 7.5% to 8.0%, or even higher, may be more appropriate.

Sleeping poorly night after night—because you are trying to burn the candle at both ends or you work night or rotating shifts—has long-term health consequences. People who don’t average at least six hours of sleep a night are more likely to be overweight or develop various medical problems. New research from Harvard-affiliated Brigham and Women’s Hospital shows that lack of sleep plays a complex and powerful role in the development of type 2 diabetes. Among volunteers who lived in a sleep lab for several weeks, their bodies made less insulin after meals when they got under 5.5 hours of sleep a night for three weeks. As a result, their blood sugar levels went haywire. Some of the people had blood sugar levels high enough to have been diagnosed as prediabetic.

In a proactive effort to help stem healthcare spending, nine medical specialty organizations have published their top 5 lists of tests, treatments, or services that are unnecessary or at least should include a thorough conversation between patients and their doctors regarding the benefits and risks of before undertaking the procedure. The lists are part of a campaign called Choosing Wisely, organized by the American Board of Internal Medicine Foundation. The purpose of making these lists, says the foundation, is to help doctors and their patients talk about tests and procedures in order to choose the ones that are supported by evidence; don’t duplicate other tests or procedures; are free from harm; and are really needed.

Today is National Walking Day. Join the celebration by taking a walk. This particular health observance is sponsored by the American Heart Association (AHA). Although it applies to everyone, it’s really aimed at adults who spend most of the workday sitting. The heart association hopes to get workers out of the office, store, or factory for a 30-minute walk. And not just today, but every day. If you don’t exercise, or do it only now and then, walking is an excellent way to get more physical activity. Just 30 minutes a day of brisk walking (or other moderate exercise), helps your heart, blood vessels, muscles, brain, and the rest of your body. If you don’t usually exercise, use National Walking Day as an invitation to get started. If you do exercise, use the day to invite a friend to get on the path to better health with a walk.

Bisphenol A, or BPA, has been used for decades to make hard plastic water bottles and to coat the inside of food cans. Tiny amounts of BPA migrate from these containers into water or food, and then into people. BPA is thought to mimic the effects of the hormone estrogen, which can interfere with growth and throw off normal hormonal interactions. In 2008, the Natural Resources Defense Council petitioned the FDA to ban the use of BPA in food packaging. The FDA finally responded last week. It denied the petition, saying the organization didn’t provide compelling data to make the case for a ban. The FDA didn’t rule out further action. In the meantime, there are several things you can do to minimize your BPA exposure.

For decades, the word “autism” meant an immutable brain disorder, one determined solely by genes and that was only marginally responsive to therapies. Today it is coming to mean something different and more manageable. A growing body of research is dramatically changing the face and future of autism. In The Autism Revolution, a new book from Ì첩ÌåÓý Publishing that I wrote with Karen Weintraub, I explain this evolution in autism science and offer strategies for families to help their children right now. One practical finding is that autism is not just a brain disorder but a whole-body condition. Treating digestive and immune system problems can make a profound difference in the family’s life, and even in the autism itself. Another finding is that autism may not necessarily be fixed for life, and that some kids improve with time and treatment.

For many people, gambling now and then is a bit of fun. For as many as two million Americans, though, gambling is addiction that can be as intense and harmful as an addiction to alcohol or drugs. “Change Your Gambling, Change Your Life,” a new book from Ì첩ÌåÓý Publishing, offers a guide for anyone looking to take a self-help approach to recovery from gambling addiction. The book offers a series of self-help tests to evaluate the depth of a person’s gambling problem and analyze its context. It also includes a toolbox of practical strategies and approaches to control the urge to gamble, and advice for avoiding slips and backslides. “Change Your Gambling, Change Your Life” was written by Dr. Howard J. Shaffer, a pioneer in the field of gambling addiction, with co-authors Ryan Martin, PhD, John Kleschinsky, MPH, and Liz Neporent, MA.

A new study from the Harvard School of Public Health suggests that a steady diet of red meat increases the odds of dying prematurely. In the study of more than 121,000 men and women, every extra daily serving of unprocessed red meat (steak, hamburger, pork, etc.) increased the risk of dying prematurely by 13%. Processed red meat (hot dogs, sausage, bacon, and the like) upped the risk by 20%. In absolute terms, the increase isn’t so scary. Among women, the death rate was 7 per 1,000 women per year among those eating about one serving of red meat a week, and 8.5 per 1,000 women per year among those eating two servings a day. The increased risk from red meat may come from the saturated fat, cholesterol, and iron it delivers. Potentially cancer-causing compounds generated when cooking red meat at high could also contribute. Sodium, particularly in processed foods, may also play a role.

This weekend, most Americans will follow the annual ritual of setting their clocks ahead one hour—and lose an hour of sleep in the process. We pay for it on Monday. According to sleep expert Dr. Charles Czeisler, U.S. researchers have seen increases of 6% to 17% in motor vehicle crashes on the Mondays after we […]

Active-play videogames, also known as exergames, are a high-tech approach to fitness that could help some people become more active and stay that way. As described in the March 2012 Harvard Heart Letter, exergames offer muscle-strengthening workouts, balance and stretching games, aerobic exercises and dancing, martial arts, and simulated recreational activities such as golf, skiing, and more. Current exergames deliver moderate workouts at best. Some fitness and senior centers now incorporate exergames into their facilities. For a home system, you’ll probably spend about $250 for the basics â€� console, accessories such as handheld controls or balance board, and software.

More and more parents are “redshirting” their young ones. That’s the practice of not starting a child in kindergarten until after his or her sixth birthday. Ann Densmore, EdD, an expert in language and social communication skills in children and co-author of Your Successful Preschooler, said parents do this to gain competitive advantages for their children and as a response to the shift in what kindergarten is. You can help prepare your children for kindergarten by ensuring there is adequate facilitated play in preschool. On the community level, talk with teachers, principals, and other parents. Challenge school committees. And realize that starting kindergarten is a new beginning for a child and his or her parents.

Children who snore, or sometimes stop breathing during sleep for a few seconds then recover with a gasp (a pattern known as sleep apnea), are more likely to become hyperactive, overly aggressive, anxious, or depressed, according to a new new study in the journal Pediatrics. How could snoring or apnea contribute to behavioral or emotional problems? It is possible that nighttime breathing problems during the brain’s formative years decrease the supply of oxygen to the brain. That could interfere with the development of pathways that control behavior and mood. It is also possible that breathing problems disturb sleep, and it’s the interrupted or poor sleep by itself that may cause trouble in the developing brain.

Drinking in the workplace may be an emerging trend, but it isn’t necessarily a healthy one. Although drinking on the job may not be as widespread as portrayed on the hit TV show Mad Men, it is still with us. About 8% of full-time employees report having five or more drinks on five or more occasions a month, and one survey showed that 23% of upper-level managers reported drinking during work hours in the prior month. In the United States, excessive drinking costs $223 billion a year. Some of these costs are generated by the nearly 18 million Americans who are alcoholics or have alcohol-related problems. But some also comes from a nearly invisible group, “almost alcoholics.”

Games are meant to be fun and exciting. Some involve the body, some the mind. Others do both. Researchers are tapping into this engagement to use games to heal an ailing mind or body. Researchers are testing virtual reality to help people with mental and physical problems ranging from post-traumatic stress disorder and stroke rehabilitation to smoking cessation and stuttering. Exergames may also help people become more physically active. Although they won’t help you lose weight or train for a marathon, many meet the American Heart Association’s criteria for “moderate-intensity daily activity,” meaning they could stand in for taking a walk.

An epileptic seizure is a frightening thing to experience, and almost as frightening to watch. Fortunately, most seizures stop on their own after a couple minutes. Any that last longer than five to 10 minutes (doctors call a long-lasting seizure status epilepticus) are a medical emergency and must be halted with medication. A new study shows that delivering anti-seizure medication with a hand-held auto-injector—much like the epi pens used by people with life-threatening allergies—is better than delivering them intravenously. This study could pave the way for home treatment of epileptic seizures.

Most of the changes that come with pregnancy—growing a belly “bump,” being tired, mood swings, cravings for particular foods, and the like—are normal, temporary, and harmless. Two other changes, pregnancy-related high blood pressure and diabetes, may have long-lasting implications for heart health. The development of high blood pressure during pregnancy is known as preeclampsia; pregnancy-related diabetes is called gestational diabetes. They are different from “regular” high blood pressure and diabetes because both are “cured” by delivery. A new study published this week in the journal Circulation suggests that these complications boost a woman’s risk of cardiovascular disease during middle age.

I’m a big fan of diet soda. I like the taste, and I love that it doesn’t have any calories. I can drink two or three diet sodas a day and not worry about gaining weight. But a new study has me wondering if enjoying the sweetness of soda without the sugar and calories is such a good thing after all. University of Miami and Columbia University researchers found that daily diet soda drinkers were more likely to have had a stroke or heart attack over the course of a 10-year study, or to have died from vascular disease, as folks who didn’t imbibe diet soda. My husband gently (but persistently) tells me there is nothing good about drinking diet soda, not even the taste I claim to enjoy so much. The evidence seems to be backing him up.
