Health Tip: Zinc in Your Diet

(HealthDay News) - Zinc is a mineral that the body needs to help the immune system, in wound healing, and in the breakdown of carbohydrates. Second only to iron in its concentration in the body, zinc is found in protein-rich foods such as meat, peanuts and peanut butter, and legumes. If you're not getting enough zinc, here's a list of possible warning signs, courtesy of the U.S. National Library of Medicine:

· Slow growth rate.

· No appetite.

· Slow-healing wounds, lesions on the skin, and persistent infections.

· Hair loss.

· Abnormalities in your ability to taste and smell.

· Difficulty seeing in the dark.

· Insufficient hormone production in men.

Fruit may reduce Alzheimer's risk

ITHACA, N.Y., Jan. 31 (UPI) -- Apples, bananas and oranges protect against neurodegenerative diseases, including Alzheimer's disease, New York researchers said. Chang Y. Lee of Cornell University in Ithaca, N.Y., said apples, bananas and oranges are the most common fruits in Western and Asian diets and are important sources of vitamins, minerals and fiber. The Cornell University researchers investigated the effects of apple, banana and orange extracts on neuron cells and found that the phenolic phytochemicals of the fruits prevented neurotoxicity on the cells.

The study, published in the Journal of Food Science, said among the three fruits, apples contained the highest content of protective antioxidants, followed by bananas and then oranges. The study demonstrated that antioxidants in the major fresh fruits consumed in the United States protected neuronal cells from oxidative stress," the authors said in a statement. "Additional consumption of fresh fruits such as apples, bananas and oranges may be beneficial to improve effects in neurodegenerative diseases such as Alzheimer's."

BOOK REVIEW

Beyond the Zonules of Zinn: A Fantastic Journey Through Your Brain (2008) By David Bainbridge

In this geographical tour of the nervous system, readers will find an entertaining and enlightening history of neuroscience and a look at the anatomy of the brain. A clinical anatomist at Cambridge University, Bainbridge (The X in Sex) has had ample opportunity to examine the brain and ponder its origins and function—as well as the many strange and marvelous names of its parts, labeled long before anyone knew what they did. The Zonules of Zinn—a name from an ancient map, from a souk, from another galaxy—are small fibers attached to the lens of the eye that adjust it for seeing at different distances. Bainbridge discusses the history and function of each name: in addition to hillocks and pyramids are the Almonds (amygdalae), part of the emotional response system, and the locus coeruleus, or sky-blue place, involved in alertness and stress. Your brain even has its own Area 51, thanks to a German neuroanatomist whose system of numbering different regions of the cerebral cortex is still used today. Bainbridge's tour also includes short discussions of nervous system disorders like multiple sclerosis and epilepsy. The book's relaxed pace, interesting tangents and broad coverage make this book eminently suitable for anyone curious about the brain. 30 b&w illus.

Patterns: A Video Game, an M.R.I. and What Men’s Brains Do By ERIC NAGOURNEY

Why does it often seem that men enjoy playing video games more than women? Perhaps because they do.

A new study finds that when men play the games, a part of the brain involved in feelings of reward and addiction becomes much more activated than it does in women.

This may explain why men are more likely to report feeling addicted to video games than women are, the researchers say in an online article in The Journal of Psychiatric Research. ... The study found that in the men, there was much more activity in the mesocorticolimbic system.

Strokes cause brain damage in three minutes, report scientists by Deborah Jones

VANCOUVER, Canada (AFP) - Strokes cause brain damage within three minutes, scientists reported Thursday, casting doubt on the common public perception that all strokes can be medically treated within three hours.

The findings show that prevention is the best strategy for one of the top killers in the developed world, said Dr. Tim Murphy, a neuroscientist at the University of British Columbia in this Western Canadian city.

Some people can be helped within that time, but "I'm saying, there are structural changes that happen very early on, and so the best thing is to manage risk factors and alter lifestyle," Murphy said.

About 80 percent of strokes are ischemic, and are caused by a clot blocking blood flow to the brain, according to the Heart and Stroke Foundation of Canada, which helped to fund the research.

Chronic Pain Harms Brain's Wiring

FRIDAY, Feb. 8 (HealthDay News) -- Chronic pain can disrupt brain function and cause problems such as disturbed sleep, depression, anxiety and difficulty making simple decisions, a U.S. study finds.

Researchers at Northwestern University's Feinberg School of Medicine in Chicago used functional MRI to scan brain activity in people with chronic low back pain while they tracked a moving bar on a computer screen. They did the same thing with a control group of people with no pain.

In those with no pain, the brain regions displayed a state of equilibrium. When one region was active, the other regions calmed down. But in people with chronic pain, the front region of the cortex mostly associated with emotion "never shuts up," study author Dante Chialvo, an associate research professor of physiology, said in a prepared statement. This region remains highly active, which wears out neurons and alters their connections to each other. This constant firing of neurons could cause permanent damage.

Brain Circuits That Suppress Memory Found

May lead to better understanding of amnesia

THURSDAY, Jan. 10 (HealthDay News) -- Brain circuits that play a key role in memory suppression have been identified by Israeli researchers.

The findings may lead to a better understanding of the mechanisms underlying amnesia, said the researchers from The Weizmann Institute of Science in Rehovot and the Edith Wolfson Medical Center in Holon. The study appears in the Jan. 10 issue of Neuron.

EVOLUTION

Using Butterfly Time, We Can Learn Secrets Of Our Own ‘Clocks’ by Robert Lee Hotz

In the highlands of central Mexico, millions of monarch butterflies soon will stir from their winter torpor, rising from groves of oyamel firs like flowers taking flight. Their unique annual migration offers scientists a rare insight into the molecular biology of time and travel. "What good is a butterfly?" said entomologist Lincoln Brower at Virginia's Sweet Briar College. "It can tell you about the fundamental biology of all creatures on this earth. There is something so fundamental about finding your way."

In a majestic seasonal rite, a new generation of monarchs flies to Mexico every fall from summer breeding grounds in Canada. This past year, they formed a billowing wind-borne quilt of 55 million or more. On its voyage, the monarch is guided by a biochemical pendulum of genes and proteins that keep butterfly time, neurobiologist Steven Reppert at the University of Massachusetts Medical School and his colleagues reported last month in the journal PLoS Biology. Its newly analyzed internal clock likely is unique among all living creatures -- a prototype, perhaps, for the biological clocks that guide our own circadian rhythms of sleepiness and wakefulness, the scientists reported.

How Much Will Your Baby Be Like You? By Richard Laliberte

Physical Traits

The instant our children are born, we look for reflections of ourselves in them. … Seeing yourself -- and your spouse -- in your baby makes you truly feel like a family. Inheritance goes far beyond eye and hair color: Genes can even shape personality traits like leadership and spirituality. Despite startling advances in genetics, our understanding of how genes and environment interact is far from perfect. "Many traits have a large hereditary component, but genetics isn't destiny -- genes are just one influence on how kids turn out," says Joann Bodurtha, MD, professor of human genetics at Virginia Commonwealth University, in Richmond.

However, there's almost always a connection between genetics and environment. Musical talent is a classic example. People who have perfect pitch are four times more likely than those with only average singing voices to say that a relative has this natural gift. Yet research has also found that most people with perfect pitch started taking music lessons before age 6, and that only 3 percent of people who started voice lessons after age 9 have perfect pitch -- suggesting that both genetics and training affect one's singing voice. "It's simplistic to say that artistic and intelligence traits are determined by genetics, because even a gifted child needs the right environment to thrive," says Dr. Garber. Average IQ scores have gone up in the past 50 years thanks to changes such as better early-childhood education, experts say, not because we're innately smarter. And intelligence may run in families partly because bright parents tend to provide a richer learning environment -- by having more books, for example. In fact, two recent studies found that the IQ of firstborn children is slightly higher than that of their younger siblings -- possibly because they received more undivided attention.

Scientists used to think people had up to 100,000 genes -- until the Human Genome Project revealed that we actually have closer to 25,000. Why the huge overestimate? It turns out most genes are multitaskers and do their jobs by marshalling other genes -- turning them on and off or boosting their effects -- so we need fewer genes overall. As a result, few characteristics can actually be traced back to a single gene (there aren't enough genes to go around for that). Nevertheless, kids have a greater chance of inheriting some characteristics rather than others.

Reaching 100 is easier than suspected By LINDSEY TANNER

CHICAGO - Living to 100 is easier than you might think. Surprising new research suggests that even people who develop heart disease or diabetes late in life have a decent shot at reaching the century mark.

"It has been generally assumed that living to 100 years of age was limited to those who had not developed chronic illness," said Dr. William Hall of the University of Rochester.

Hall has a theory for how these people could live to that age. In an editorial in Monday's Archives of Internal Medicine, where the study was published, he writes that it might be thanks to doctors who aggressively treat these older folks' health problems, rather than taking an "ageist" approach that assumes they wouldn't benefit.

Overall, the men were functioning better than the women. Nearly three-fourths of the male survivors could bathe and dress themselves, while only about one-third of the women could.

The researchers think that may be because the men had to be in exceptional condition to reach 100. "Women, on the other hand, may be better physically and socially adept at living with chronic and often disabling conditions," wrote lead author Dr. Dellara Terry and her colleagues. "It's not just luck, it's not just genetics. ... It's lifestyle" that seems to make a big difference, said lead author Dr. Laurel Yates of Harvard's Brigham and Women's Hospital.

The Science of Fairy Tales by Chris Gorski, American Institute of Physics
Kids of any age love to read fairy tales because the storyline never limits the possibility that anything could happen. Curses, spells, and handsome princes reign in worlds beyond the reader’s imagination.

But are the most magical moments from some of our favorite stories actually possible? Basic physical principles and recent scientific research suggest that what readers might mistake for fantasies and exaggeration could be rooted in reality. So suspend your imagination for a moment, and look at the following fairy tales as a hard-core scientist might.

EDUCATION AND TEACHING

A Fresh Look at Brain-Based Education By Eric P. Jensen

It has been more than 20 years since it was first suggested that there could be connections between brain function and educational practice. In the face of all the evidence that has now accumulated to support this notion, Mr. Jensen advocates that educators take full advantage of the relevant knowledge from a variety of scientific disciplines.

TEN YEARS ago John Bruer, executive administrator of the James S. McDonnell Foundation, began a series of articles critical of brain-based education. They included "Education and the Brain: A Bridge Too Far" (1997), "In Search of . . . Brain-Based Education" (1999), and, most recently, "On the Implications of Neuroscience Research for Science Teaching and Learning: Are There Any?" (2006).1 Bruer argued that educators should ignore neuroscience and focus on what psychologists and cognitive scientists have already discovered about teaching and learning. His message to educators was "hands off the brain research," and he predicted it would be 25 years before we would see practical classroom applications of the new brain research. Bruer linked brain-based education with tabloid mythology by announcing that, if brain-based education is true, then "the pyramids were built by aliens -- to house Elvis."2

Because of Bruer's and others' critiques, many educators decided that they were simply not capable of understanding how our brain works. Other educators may have decided that neuroscience has nothing to offer and that the prudent path would be simply to ignore the brain research for now and follow the yellow brick road to No Child Left Behind. Maybe some went so far as to say, "What's the brain got to do with learning?" But brain-based education has withstood the test of time, and an accumulating body of empirical and experiential evidence confirms the validity of the new model.

How to Make Great Teachers By CLAUDIA WALLIS

We never forget our best teachers - those who imbued us with a deeper understanding or an enduring passion, the ones we come back to visit years after graduating, the educators who opened doors and altered the course of our lives. I was lucky enough to encounter two such teachers my senior year in a public high school in Connecticut. Dr. Cappel told us from the outset that his goal was not to prepare us for the AP biology exam; it was to teach us how to think like scientists, which he proceeded to do with a quiet passion, mainly in the laboratory. Mrs. Hastings, my stern, Radcliffe-trained English teacher, was as devoted to her subject as the gentle Doc Cappel was to his: a tough taskmaster on the art of writing essays and an avid guide to the pleasures of James Joyce. Looking back, I'd have to credit this inspirational pair for carving the path that led me to a career writing about science.

There's no magic formula for what makes a good teacher, but there is general agreement on some of the prerequisites. One is an unshakable belief in children's capacity to learn. "Anyone without this has no business in the classroom," says Margaret Gayle, an expert on gifted education at Duke University, who has trained thousands of teachers in North Carolina. Another requirement, especially in the upper grades, is a deep knowledge of one's subject. According to research on teacher efficacy by statistician William Sanders, the higher the grade, the more closely student achievement correlates to a teacher's expertise in her field. Nationally, that's a problem. Nearly 30% of middle- and high school classes in math, English, science and social studies are taught by teachers who didn't major in a subject closely related to the one they are teaching, according to Richard Ingersoll, professor of education and society at the University of Pennsylvania. In the physical sciences, the figure is 68%. In high-achieving countries like Japan and South Korea, he says, "you have far less of this misassignment going on."

Other essential skills require on-the-job practice. It takes at least two years to master the basics of classroom management and six to seven years to become a fully proficient teacher. Unfortunately, a large percentage of public-school teachers give up before they get there. Between a quarter and a third of new teachers quit within their first three years on the job, and as many as 50% leave poor, urban schools within five years. Hiring new teachers is "like filling a bucket with a huge hole in the bottom," says Thomas Carroll, president of the National Commission on Teaching and America's Future, a Washington-based nonprofit.

MUSIC

Music speeds recovery from stroke: study by Marlowe Hood

PARIS (AFP) - A daily dose of one's favourite pop melodies, classical music or jazz can speed recovery from debilitating strokes, according to a study published Wednesday. When stroke patients in Finland listened to music for a couple of hours each day, verbal memory and attention span improved significantly compared to patients who received no musical stimulation, or who listened only to stories read aloud,the study reported.

Those exposed to music also experienced less depression than the other two control groups.

Three months after a stroke, verbal memory was boosted by 60 percent in music listeners, by 18 percent in audio book listeners, and by 29 percent in non-listeners, the lead author Teppo Sarkamo, a neuroscientist at Helsinki University, told AFP.

PSYCHOLOGY

Inside the Mind of the Boy Dating Your Daughter

The stereotype of the 16-year-old boy is that he has sex on the brain. But a fascinating new report suggests that boys are motivated more by love and a desire to form real relationships with the girls they date. The report, published in this month’s Journal of Adolescence, paints a far different picture of teen boys than the stereotype of testosterone-fueled youth. Psychology researchers from the State University of New York at Oswego surveyed 105 10th-grade boys whose average age was about 16. The boys, most of whom said they were heterosexual, were given surveys asking them to select various reasons why they asked girls out, dated and pursued physical relationships. Most of the boys had dating experience, and about 40 percent were sexually active.

The boys were asked their reasons for dating and were allowed to mark more than one answer. Notably, being physically attracted to someone wasn’t the primary motivation they gave for dating. More than 80 percent of the boys noted “I really liked the person.'’ Physical attraction and wanting to get to know someone better were the second most popular answers.

Sad, self-absorbed shoppers spend more

Study: Even a temporary bout of the blues can lead to extravagant buys

BOSTON - If you’re sad and shopping, watch your wallet: A new study shows people’s spending judgment goes out the window when they’re down, especially if they’re a bit self-absorbed. Study participants who watched a sadness-inducing video clip offered to pay nearly four times as much money to buy a water bottle than a group that watched an emotionally neutral clip.

The so-called “misery is not miserly” phenomenon is well-known to psychologists, advertisers and personal shoppers alike, and has been documented in a similar study in 2004. The new study released Friday by researchers from four universities goes further, trying to answer whether temporary sadness alone can trigger spendthrift tendencies.

Solitude vs Loneliness By: Hara Estroff Marano

Loneliness is marked by a sense of isolation. Solitude, on the other hand, is a state of being alone without being lonely and can lead to self-awareness.

As the world spins faster and faster—or maybe it just seems that way when an email can travel around the world in fractions of a second—we mortals need a variety of ways to cope with the resulting pressures. We need to maintain some semblance of balance and some sense that we are steering the ship of our life.

Otherwise we feel overloaded, overreact to minor annoyances and feel like we can never catch up. As far as I'm concerned, one of the best ways is by seeking, and enjoying, solitude. That said, there is an important distinction to be established right off the bat. There is a world of difference between solitude and loneliness, though the two terms are often used interchangeably.

HEALTH

Scientists Find New Receptor for H.I.V. By LAWRENCE K. ALTMAN

SAN FRANCISCO — Government scientists have discovered a new way that H.I.V. attacks human cells, an advance that could provide fresh avenues for the development of additional therapies to stop AIDS, they reported on Sunday.

The discovery is the identification of a new human receptor for H.I.V. The receptor helps guide the virus to the gut after it gains entry to the body, where it begins its relentless attack on the immune system.

For years, scientists have known that H.I.V. rapidly invades the lymph nodes and lymph tissues that are abundant throughout the gut, or intestines. The gut becomes the prime site for replication of H.I.V., and the virus then goes on to deplete the lymph tissue of the key CD4 H.I.V.-fighting immune cells.

Diabetes Health Goes Beyond Blood Sugar By TARA PARKER-POPE

The startling findings of a major federal study on the effects of lowering blood sugar are unlikely to change the way most people with Type 2 diabetes manage their illness, doctors said Thursday. The New England Journal of Medicine published a study this week showing that a three-pronged approach of managing sugar, blood pressure and cholesterol — combined with low doses of aspirin — prolonged the lives of people with diabetes. The patients who did best in that study did not reach the nearly normal sugar levels that were the aim of the Accord study. Instead, their levels were just slightly higher than normal.

In the Accord study, the group of patients who were randomly assigned to lower their blood sugar levels to nearly normal had 54 more deaths than the group whose levels were less rigidly controlled. The patients were in the study for an average of four years when investigators stopped the intense regimen and put all of them on the less intense one. “When we look at mortality in patients with Type 2 diabetes, it’s not only the blood sugar,” said Dr. Joel Zonszein, director of the Clinical Diabetes Center at Montefiore Medical Center in the Bronx. “What the study shows is that just lowering blood sugar is not protecting you from dying sooner. Blood sugar is important, but so is blood pressure and cholesterol.”

Low-Carb Diets Better Than Low-Fat Diets at Preventing Diabetes By Amanda Gardner
THURSDAY, Feb. 7 (HealthDay News) -- A diet low in carbohydrates but high in animal fat and protein doesn't seem to increase the risk of type 2 diabetes in women, a new study claims. "One study is never enough to change a recommendation, but this study is interesting in that it shows that a low-fat diet is no better than a low-carbohydrate diet in preventing type 2 diabetes," said Thomas Halton, lead author of a study in the current issue of the American Journal of Clinical Nutrition. "The one diet that did seem to show a protective effect was a vegetable-based, low-carb diet which consisted of higher amounts of vegetable fat and vegetable protein, and lower amounts of carbohydrate."

The findings, Halton added, were a bit surprising in that most doctors and nutritionists recommend a low-fat diet to prevent type 2 diabetes. "This study showed that a low-fat diet didn't really prevent type 2 diabetes in our cohort when compared to a low-carb diet. I was also surprised that total carbohydrate consumption was associated with type 2 diabetes, and that the relative risk for the glycemic load was so high."

Siestas and Your Heart: Can You Nap Your Way to Health? From Harvard Health Publications

Here in the United States, many people consider eight hours an ideal amount of sleep — and most of them expect those eight hours to come in one block at night. But in Latin America, Mediterranean countries, and other parts of the world, the ideal slumber follows quite a different pattern. In sunny climates, people like to retreat from the heat and stress of a busy day for an afternoon siesta, then make up the difference by staying up late at night.

Cultural norms evolve to suit the needs and preferences of particular societies. But human biology is much the same in Athens and Chicago. Perhaps, then, a study of siestas in Greece will help Americans understand their own choices for healthful sleep. The study also raises the interesting possibility that a daily siesta may help ward off heart disease.

To look for a link between siestas and the risk of heart disease, scientists from the University of Athens Medical School and the Harvard School of Public Health studied 23,681 Greek men and women. All the volunteers were free of diagnosed heart diseases, cancer, and stroke when they enrolled in the study between 1994 and 1999. They all reported on their napping habits; the researchers classified them as regular nappers, occasional nappers, or non-nappers. They also collected information on all the participants’ age, education, smoking status, employment, exercise level, diet, body mass index, and waist-to-hip ratio.

The subjects were tracked for an average of 6.3 years; in this period, 133 members of the group died from coronary artery disease. As expected, advancing age, smoking, and abdominal obesity were linked to an increased risk of cardiac death, while exercise, a good diet, increased education, and gainful employment appeared protective. Surprisingly, though, midday napping was also protective, especially for men.

Gentlemen, 5 Easy Steps to Living Long and Well By NICHOLAS BAKALAR

Living past 90, and living well, may be more than a matter of good genes and good luck. Five behaviors in elderly men are associated not only with living into extreme old age, a new study has found, but also with good health and independent functioning.

The behaviors are abstaining from smoking, weight management, blood pressure control, regular exercise and avoiding diabetes. The study reports that all are significantly correlated with healthy survival after 90.

While it is hardly astonishing that choices like not smoking are associated with longer life, it is significant that these behaviors in the early elderly years — all of them modifiable — so strongly predict survival into extreme old age.

“The take-home message,” said Dr. Laurel B. Yates, a geriatric specialist at Brigham and Women’s Hospital in Boston who was the lead author of the study, “is that an individual does have some control over his destiny in terms of what he can do to improve the probability that not only might he live a long time, but also have good health and good function in those older years.”

The High Metabolism Diet By Selene Yeager, Prevention

Essential eating rules that stoke your fat burn all day long

You probably don't need scientists to tell you that your metabolism slows with age. But they're studying it anyway—and coming up with exciting new research to help rev it up again. The average woman gains 1 1/2 pounds a year during her adult life—enough to pack on 40-plus pounds by her 50s, if she doesn't combat the roller coaster of hormones, muscle loss, and stress that conspires to slow her fat-burning engine. But midlife weight gain isn't inevitable: We've found an exercise and diet plan that will tackle these changes.

Prevention's customizable metabolism-boosting workout will help you shed up to 8 pounds in just 4 weeks. Most important, you'll build firm, lean muscle tissue—the key to a robust metabolism.

But that's just the beginning. To really make your metabolism soar, couple the workout with our High-Metabolism Diet, developed by Dan Benardot, PhD, RD, an associate professor of nutrition and kinesiology at Georgia State University, and Tammy Lakatos, RD, coauthor of Fire Up Your Metabolism. Start today and you'll sleep better, have more energy, feel firmer, and notice your clothes are looser in as little as 2 weeks. Here's how:

Eat Enough

Rev Up in the Morning

Drink Coffee or Tea

Fight Fat with Fiber

Buy the Big Bottle

Go Organic

Always Include Protein

Eat Iron-Rich Foods

Get More D

Skip the Second Cocktail

Drink Milk

Food for Thought By Rachael Moeller Gorman

As an organ, the brain is no mere blood-pump or air filter. It's more. It's you. That's why dementia is so devastating, and why these words from Greg Cole, Ph.D., are so heartening: "For the majority of people, studies are showing you can probably slow down cognitive decline enough to escape disease altogether," says Cole, associate director of the Alzheimer's Disease Research Center at the University of California, Los Angeles. Though Cole doesn't know exactly how to do this (nor does anyone else), eating habits might help.

How? As we age, our brains turn more sluggish as globs of a protein called amyloid accumulate between our neurons (nerve cells). Inflammation and oxidative damage accompany this protein buildup, nicking cell membranes and interrupting signals between neurons. Typically, this poses no real problem—a few "senior moments" here and there. But a downward dementia spiral can occur in some people if over time too many proteins gunk together and too much inflammation and oxidative damage erodes cells.

Bedtime Snacks that Help You Sleep By Joy Bauer, M.S., R.D., C.D.N.

One of the best natural sedatives is tryptophan, an amino acid component of many plant and animal proteins. Tryptophan is one of the ingredients necessary for the body to make serotonin, the neurotransmitter best known for creating feelings of calm, and for making you sleepy. However, the trick is to combine foods that have some tryptophan with ample carbohydrate. That’s because in order for insomnia-busting tryptophan to work, it has to make its way to the brain.

Unfortunately, all amino acids compete for transport to the brain. When you add carbs, they cause the release of insulin, which takes the competing amino acids and incorporates them into muscle…but leaves tryptophan alone, so it can make its way to the brain, be converted to serotonin, and cause sleepiness.

Serotonin-producing bedtime snacks should be no more than 200 calories and should be eaten at least 30 minutes prior to bed.

Brain and mind wonders: Newsletter 3 - 2008

Hi to all

Here is the newsletter for the past two weeks. Many interesting articles which I hope you have time to read.

TIDBITS

  • ADHD: The Family Tree - Parents whose children have attention deficit more likely to have mood and anxiety disorders. Parents of kids with attention deficit hyperactivity disorder (ADHD) are 24 times as likely to suffer from the disorder themselves as are parents of children without the disorder, according to a study in the Journal of the American Academy of Child & Adolescent Psychiatry. Parents whose children had both ADHD and oppositional defiant disorder or conduct disorder were found more likely to have mood, anxiety and substance-abuse disorders than other parents. Living with kids who have ADHD can exacerbate a parent's own problems and vice versa, says Andrea Chronis, a psychologist at the University of Maryland. http://www.psychologytoday.com/articles/pto-20040628-000001.html
  • You don't have to say no to nuts! Nuts are a good source of fiber, protein, complex carbohydrate and protein. They also are good sources of potassium, phosphorus, magnesium and iron. Because they're also high in fat (not saturated fat), limit your nuts to an occasional serving of one ounce. Enjoy almonds, walnuts and pecans for a healthy energy boost.
  • Enjoy fresh or frozen vegetables, depending on your preferences, lifestyle and budget. The nutrient content of raw and cooked veggies is similar, but cooking some vegetables increases the nutrient content over raw. When vegetables are cooked, the body uses minute phytochemicals called antioxidants to repair cell damage caused by "free radicals," toxic byproducts of normal metabolism and the environment.
  • Flaxseed for Hot Flashes? New research suggests that lignans, estrogen-like compounds in flaxseeds, may help relieve hot flashes. In the pilot study, 28 women consumed four tablespoons of ground flaxseed daily—two in the morning, two at night. After six weeks, the frequency of their hot flashes dropped, on average, from 7.3 to 3.6 a day. Intensity of the hot flashes decreased too. "[Lignans in] flax offer a ‘natural,’ less potent estrogen effect on hot flashes than synthetic hormone therapy," says the study’s lead author, Sandhya Pruthi, M.D., of the Mayo Clinic in Rochester, Minnesota, who is planning a larger study to confirm the findings. Pruthi recommends starting with two tablespoons daily and working up to four. (Note: 4 tablespoons = 190 calories.) Flaxseeds are rich in fiber—2.5 grams per tablespoon—so increasing intake too quickly can cause bloating. Grind whole flax—a coffee grinder works great—and sprinkle it on yogurt, cereal, fruit and salads.

BRAIN

What Are We Thinking When We (Try to) Solve Problems? By Nikhil Swaminathan

New research indicates what happens in the brain when we're faced with a dilemma

Aha! Eureka! Bingo! "By George, I think she's got it!" Everyone knows what it's like to finally figure out a seemingly impossible problem. But what on Earth is happening in the brain while we're driving toward mental pay dirt? Researchers eager to find out have long been on the hunt, knowing that such information could one day provide priceless clues in uncovering and fixing faulty neural systems believed to be behind some mental illnesses and learning disabilities.

Researchers at Goldsmiths, University of London report in the journal PLoS ONE that they monitored action in the brains of 21 volunteers with electroencephalography (EEG) as they tackled verbal problems in an attempt to uncover what goes through the mind—literally—in order to observe what happens in the brain during an "aha!" moment of problem solving.

In many cases, the subjects hit a wall, or what researchers refer to as a "mental impasse." If the participants arrived at this point, they could press a button for a clue to help them untangle a problem. Bhattacharya says blocks correlated with strong gamma rhythms (a pattern of brain wave activity associated with selective attention) in the parietal cortex, a region in the upper rear of the brain that has been implicated in integrating information coming from the senses. The research team noticed an interesting phenomenon taking place in the brains of participants given hints: The clues were less likely to help if subjects had an especially high gamma rhythm pattern. The reason, Bhattacharya speculates, is that these participants were, in essence, locked into an inflexible way of thinking and less able to free their minds, and thereby unable to restructure the problem before them. "If there's excessive attention, it somehow creates mental fixation," he notes. "Your brain is not in a receptive condition."

10 Ways We Get the Odds Wrong By: Maia Szalavitz
Our brains are terrible at assessing modern risks. Here's how to think straight about dangers in your midst.

Is your gym locker room crawling with drug-resistant bacteria? Is the guy with the bulging backpack a suicide bomber? And what about that innocent-looking arugula: Will pesticide residue cause cancer, or do the leaves themselves harbor E. coli? But wait! Not eating enough vegetables is also potentially deadly.

These days, it seems like everything is risky, and worry itself is bad for your health. The more we learn, the less we seem to know—and if anything makes us anxious, it's uncertainty. At the same time, we're living longer, healthier lives. So why does it feel like even the lettuce is out to get us?

The human brain is exquisitely adapted to respond to risk—uncertainty about the outcome of actions. Faced with a precipice or a predator, the brain is biased to make certain decisions. Our biases reflect the choices that kept our ancestors alive. But we have yet to evolve similarly effective responses to statistics, media coverage, and fear-mongering politicians. For most of human existence, 24-hour news channels didn't exist, so we don't have cognitive shortcuts to deal with novel uncertainties.

Still, uncertainty unbalances us, pitching us into anxiety and producing an array of cognitive distortions. Even minor dilemmas like deciding whether to get a cell phone (brain cancer vs. dying on the road because you can't call for help?) can be intolerable for some people. And though emotions are themselves critical to making rational decisions, they were designed for a world in which dangers took the form of predators, not pollutants. Our emotions push us to make snap judgments that once were sensible—but may not be anymore.

Getting Duped: How the Media Messes with Your Mind By Yvonne Raley and Robert Talisse

Statements made in the media can surreptitiously plant distortions in the minds of millions. Learning to recognize two commonly used fallacies can help you separate fact from fiction

In 2003 nearly half of all Americans falsely assumed that the U.S. government had found solid evidence for a link between Iraq and al Qaeda. What is more, almost a quarter of us believed that investigators had all but confirmed the existence of weapons of mass destruction in Iraq, according to a 2003 report by the University of Maryland’s Program on International Policy Attitudes and Knowledge Networks, a polling and market research firm. How did the true situation in Iraq become so grossly distorted in American minds?

News shows often have an implicit bias that may motivate the portrayal of facts and opinions in misleading ways, even if the information presented is largely accurate. Nevertheless, by becoming familiar with how spokespeople can create false impressions, media consumers can learn to ignore certain claims and thereby avoid getting duped. We have detected two general types of fallacies—one of them well known and the other newly identified—that have permeated discussion of the Iraq War and that are generally ubiquitous in political debates and other discourse.

One common method of spinning information is the so-called straw man argument. In this tactic, a person summarizes the opposition’s position inaccurately so as to weaken it and then refutes that inaccurate rendition.

Weak man tactics are harder to detect than those of the straw man variety. Because straw man arguments are closely related to an opponent’s true position, a clever listener might be able to spot the truth amid the hyperbole, understatement or other corrupted version of that view. A weak man argument, however, is more opaque because it contains a grain of truth and often bears little similarity to the stronger arguments that should also be presented. Therefore, a listener has to know a lot more about the situation to imagine the information that a speaker or writer has cleverly disregarded.

Lead linked to aging in older brains By MALCOLM RITTER

NEW YORK - Could it be that the "natural" mental decline that afflicts many older people is related to how much lead they absorbed decades before?

That's the provocative idea emerging from some recent studies, part of a broader area of new research that suggests some pollutants can cause harm that shows up only years after someone is exposed.

The new work suggests long-ago lead exposure can make an aging person's brain work as if it's five years older than it really is. If that's verified by more research, it means that sharp cuts in environmental lead levels more than 20 years ago didn't stop its widespread effects.

"We're trying to offer a caution that a portion of what has been called normal aging might in fact be due to ubiquitous environmental exposures like lead," says Dr. Brian Schwartz of Johns Hopkins University.

"The fact that it's happening with lead is the first proof of principle that it's possible," said Schwartz, a leader in the study of lead's delayed effects. Other pollutants like mercury and pesticides may do the same thing, he said.

In fact, some recent research does suggest that being exposed to pesticides raises the risk of getting Parkinson's disease a decade or more later. Experts say such studies in mercury are lacking.

EDUCATION & MATHEMATICS

Professor: Fractions should be scrapped By Maureen Milford

PHILADELPHIA — A few years ago, Dennis DeTurck, an award-winning professor of mathematics at the University of Pennsylvania, stood at an outdoor podium on campus and proclaimed, "Down with fractions!"

"Fractions have had their day, being useful for by-hand calculation," DeTurck said as part of a 60-second lecture series. "But in this digital age, they're as obsolete as Roman numerals are."

The speech started a firestorm, particularly after the university posted it online.

"There were blogs and rants, and there were some critical e-mails," said DeTurck, who is now dean of the college of arts and sciences at Penn. "They'd always boil down to: 'What would we do in cooking and carpentry?' "

DeTurck is stirring the pot again, this time in a book scheduled to be published this year. Not only does he favor the teaching of decimals over fractions to elementary school students, he's also taking on long division, the calculation of square roots and by-hand multiplication of long numbers.

Teacher Burnout? Blame the Parents

The stress of teaching is often blamed on rowdy students and unrealistic expectations from school officials. But new research suggests that parents may be the real culprit in teacher burnout.

The study, published this month in the psychology journal Anxiety, Stress, & Coping, surveyed 118 German schoolteachers who had been teaching for an average of 20 years. The questionnaires were designed to assess personality traits like perfectionism. They also measured the teachers’ level of burnout and their reactions to pressure from colleagues, students and parents. Although “burnout” is complex and different for every teacher, it’s usually defined as occurring when a teacher feels emotionally exhausted at the end of the day, appears cynical or uncaring about what happens to students and feels as if he or she has reached few personal goals.

Although perfectionism is often linked with job stress, teachers with perfectionist tendencies in this survey weren’t more likely to have burnout. But teachers who felt pressure to be perfect or experienced criticism for being imperfect were more likely to have burnout. Notably, the highest pressure to be perfect didn’t come from students or colleagues but from parents.

Teacher absences are hurting learning

Vacuum in classroom linked to lower test scores, research shows

WASHINGTON - A year is a long time in a child's education, the time it can take to learn cursive writing or beginning algebra. It's also how much time kids can spend with substitute teachers from kindergarten through high school — time that's all but lost for learning.

Despite tremendous pressure on schools to increase instructional time and meet performance goals, the vacuum created by teacher absenteeism has been all but ignored — even though new research suggests it can have an adverse effect in the classroom.

The problem isn't just with teachers home for a day or two with the flu. Schools' use of substitutes to plug full-time vacancies — the teachers that kids are supposed to have all year — is up dramatically.

Spanish town to pay kids to read By IAIN SULLIVAN

NOBLEJAS, Spain — A small-town Spanish mayor concerned about a high dropout rate in local schools has devised a way to keep kids studying — pay them.

Agustin Jimenez, Socialist mayor of the central agricultural town of Noblejas, is recommending the town's children be given a euro — the equivalent of $1.50 — for every hour they spend reading in the local library.

The sweetener is part of a series of measures to be voted on by the Noblejas council in March. Others include funds for apartments in university towns for students from Noblejas, teachers to give private lessons to struggling students, and expert advice to parents on the virtues of keeping their children at school.

You’re 16, You’re Beautiful and You’re a Voter By ANYA KAMENETZ

THE 2008 presidential campaign has made history in many ways, not least being the arrival of a new generation at the polls. Voters under 29 were the first to anoint Barack Obama as their candidate. Reversing a general decline that began in 1972, youth turnout leapt in 2004, and in the early contests in this primary season it was up sharply.

We should hasten the enfranchisement of this generation, born between 1980 and 1995, by lowering the voting age to 16.

We know driving laws reflect reality; whoever heard of the scourge of under-age driving? On the other hand, studies have shown that three-fourths of high school seniors have drunk alcohol. Surveys show that teenagers who drink at home with their families go on to drink less than those who sneak beers with friends. Imagine 16-year-olds receiving a drinking permit upon passage of a mandatory course about alcoholism. The permit would allow a tipple only at family gatherings or school functions for two years — until you graduate or leave home.

GENETICS

The Identity Dance By: Gunjan Sinha

The idea that genes determine identity has been replaced with a new view in which DNA and life experience work together to mold personalities.

Sandra and Marisa Pena, identical twins, seem to be exactly the same. They have the same thick dark hair, the same high cheekbones, the same habit of delicately rubbing the tip of the nose in conversation. They had the same type of thyroid cyst at the same age (18) in the same place (right side). When San Diego is mentioned, they both say, simultaneously and with the same intonation, "Oh, I love San Diego!" They live together, work one floor away from each other at MTV, wear the same clothes, hang out with the same friends. They even have the same dreams.

We've come to believe that genes influence character and personality more than anything else does. It's not just about height and hair color—DNA seems to have its clutches on our very souls. But spend a few hours with identical twins, who have exactly the same set of genes, and you'll find that this simplistic belief crumbles before your eyes. If DNA dictates all, how can two people with identical genes—who are living, breathing clones of each other—be so different?

To answer such questions, scientists have begun to think more broadly about how genes and life experience combine to shape us. The rigid idea that genes determine identity has been replaced with a more flexible and complex view in which DNA and life experience conspire to mold our personalities. We now know that certain genes make people susceptible to traits like aggression and depression. But susceptibility is not inevitability. Gene expression is like putty: Genes are turned on and off, dialed up or down both by other genes and by the ups and downs of everyday life. A seminal study last year found that the ideal breeding ground for depression is a combination of specific genes and stressful triggers—simply having the gene will not send most people into despair. Such research promises to end the binary debate about nature vs. nurture—and usher in a revolution in understanding who we are.

Nature and nurture play role in mental illness By Julie Steenhuysen and Ben Hirschler

CHICAGO/LONDON (Reuters) - Variations in a gene helped shield adults who had endured child abuse from becoming depressed as adults, U.S. researchers said on Monday in a study that helps explain how nature and nurture give rise to mental illness.

And a British team has found that pregnant women who have a major emotional loss in the early months of pregnancy give birth to babies with a higher risk of schizophrenia.

The studies, published in the Archives of General Psychiatry, add to a growing understanding of how genetics and environmental distress sometimes act together to produce mental illness.

"It is not a question of genes versus environment. It is a question of how genes interact with whatever the environmental factors might be. And that is probably true of all of the disorders that we call mental illness," said Dr. Thomas Insel, director of the National Institutes of Mental Health.

Embryos created with DNA from 3 people

LONDON - British scientists have created human embryos containing DNA from two women and one man, a procedure that could potentially prevent conditions including epilepsy, diabetes and heart failure.

Though the preliminary research has raised concerns about the possibility of genetically modified babies, the scientists say that the embryos are still only primarily the product of one man and one woman.

"We are not trying to alter genes, we're just trying to swap a small proportion of the bad ones for some good ones," said Patrick Chinnery, a professor of neurogenetics at Newcastle University involved in the research.

The process aims to avoid passing onto children bad mitochondria genes, which are contained outside the nucleus in a normal female egg. Mitochondria are a cell's energy source, but mistakes in their genetic code can result in serious diseases like epilepsy, strokes, and mental retardation.

MUSIC

Under the Influence of…Music?

Teenagers listen to an average of nearly 2.5 hours of music per day. Guess what they’re hearing about?

One in three popular songs contains explicit references to drug or alcohol use, according to a new report in The Archives of Pediatrics and Adolescent Medicine. That means kids are receiving about 35 references to substance abuse for every hour of music they listen to, the authors determined.

Studies have long shown that media messages have a pronounced impact on childhood risk behaviors. Exposure to images of smoking in movies influences a child’s risk for picking up the habit. Alcohol use in movies and promotions is also linked to actual alcohol use.

“Music is well-known to connect deeply with adolescents and to influence identity development, perhaps more than any other entertainment medium,'’ said the study authors.

Music on the Mind By: Nancy K. Dess

Interviews Norman M. Weinberger, a professor of neurobiology and behavior at the University of California at Irvine, on the role of music in brain function. Elements of music; Fundamental aspect of music perception; Role of musical experience in the human brain.

Music and science may seem to inhabit different universes--one of beauty andemotion, the other of logic and reason. But now, neuroscientists are placing them in the same solar system. Norman M. Weinberger, Ph.D., professor of neurobiology and behavior at the University of California at Irvine, explains how new research is beginning to reveal the role of music in brain function--and our lives.

Nancy K. Dess: Is music in our genes?

Norman M. Weinberger: Music exists in every culture, and infants have excellent musical abilities that cannot be explained by learning. Mothers everywhere sing to their infants because babies understand it. Music seems to be part of our biological heritage.

NKD: So our brains evolved to process it?

NMW: Not in the sense that a particular chunk of brain is musical. It's complex, because music has many elements--rhythm, melody and so on. For example, certain cells in the right hemisphere respond more to melody than to language.

PSYCHOLOGY

A Child’s View of Attention Deficit

What does it feel like to have attention deficit disorder?

The answer to that question can be found in a fascinating new report from the Journal of Pediatric Nursing called “I Have Always Felt Different.'’ The article gives a glimpse into the experience of attention-deficit hyperactivity disorder, or A.D.H.D., from a child’s perspective.

Assistant professors Robin Bartlett and Mona M. Shattell, from the School of Nursing at the University of North Carolina at Greensboro, interviewed 16 college students who had been diagnosed with A.D.H.D. as children. The investigators talked to them about how the disorder affected life at home, school and friendships.

Like most kids, the students described a life of both conflict with and support from their parents. But in their case, fighting with parents was often triggered by attention-related problems like failing to complete laundry chores or cleaning their rooms.

ADHD's Outdoor Cure By: Willow Lawson

Finding relief in wide open spaces. Playing outdoors may curb the disorder.

For the 7 percent of American kids who suffer from attention deficit hyperactivity disorder (ADHD), relief may come in the form of green fields, leafy trees and open sky.

Andrea Faber Taylor and Frances Kuo, researchers at the Human Environment Research Laboratory at the University of Illinois at Urbana-Champaign, have found that spending time in ordinary "green" settings—such as parks, farms or grassy backyards—reduces symptoms of ADHD when compared to time spent at indoor playgrounds and man-made recreation areas of concrete and asphalt. The findings were consistent regardless of the child's age, gender, family income, geographic region or severity of diagnosis.

How to Remain Calm During Uneasy Times By: Hara Estroff Marano

A few physical routines can keep you in balance. We need to engage in activities that maintain anxiety at manageable levels so that we can continue to function, and so that we can respond rationally if push comes to shove and we face crises in our midst.

No doubt about it. We are living in troubled and troubling times. The economy feels remarkably uncertain. It's not just a highly erratic stock market, but the high cost of oil and the incredibly shrinking job market. Without jobs our very identity seems to shrink, to say nothing of our means for enjoying life. And the American consumer economy is threatened even further.

War talk is all around us and scenes of preparation face us on the daily news. Whether you are for or against war, America's stance on Iraq is certainly forcing this nation into unchartered waters and creating new alliances of power in the world. It is bringing on us a torrent of criticism that is at best difficult to endure and undermines whatever security we had in our position in the world. Color-coded alerts may come and go, but we also all now live with the threat of terrorism in our midst.

How do we stay sane in all the midst of all these anxiety-provoking developments?

It takes an effort.

We need to engage in activities that maintain anxiety at manageable levels so that we can continue to function, and so that we can respond rationally if push comes to shove and we face crises in our midst.

Middle age is truly depressing, study finds

But good news is that most grow happy again during golden years

LONDON - Middle age is truly miserable, according to a study using data from 80 countries showing that depression is most common among men and women in their 40s.

The British and U.S. researchers found that happiness for people ranging from Albania to Zimbabwe follows a U-shaped curve where life begins cheerful before turning tough during middle age and then returning to the joys of youth in the golden years.

Previous studies have shown that psychological well-being remained flat throughout life but the new findings to be published in the journal Social Science & Medicine suggest we are in for a topsy-turvy emotional ride.

Dad baboons help their daughters mature

WASHINGTON - Having daddy around when they are growing up is good for little girls — even if they are little baboon girls. While that's well known for people, it's a bit of a surprise for non-human primates.

But a report in Monday's online edition of Proceedings of the National Academy of Sciences found that female baboons in Kenya raised in groups with their fathers matured earlier and had a longer reproductive life than other baboons.

Males had not been thought to be engaged in a level of care that would make any difference to their offspring, said Susan Alberts, an associate professor of biology at Duke University.

Alberts and colleagues studied groups of yellow baboons living near Kenya's Mt. Kilimanjaro. In these groups both males and females have several partners.

The presence of the father in a group gave the daughters a jump-start on sexual maturity, a measure of fitness, the researchers said.

Coping With the Caveman in the Crib By TARA PARKER-POPE

If there is such a person as a “baby whisperer,” it is the pediatrician Dr. Harvey Karp, whose uncanny ability to quiet crying babies became the best-selling book “The Happiest Baby on the Block.”

In his latest book, “The Happiest Toddler on the Block,” Dr. Karp tries to teach parents the skills to communicate with and soothe tantrum-prone children. In doing so, however, he redefines what being a toddler means. In his view, toddlers are not just small people. In fact, for all practical purposes, they’re not even small Homo sapiens.

Dr. Karp notes that in terms of brain development, a toddler is primitive, an emotion-driven, instinctive creature that has yet to develop the thinking skills that define modern humans. Logic and persuasion, common tools of modern parenting, “are meaningless to a Neanderthal,” Dr. Karp says.

The challenge for parents is learning how to communicate with the caveman in the crib. “All of us get more primitive when we get upset, that’s why they call it ‘going ape,’ ” Dr. Karp says. “But toddlers start out primitive, so when they get upset, they go Jurassic on you.”

Caffeine ups blood sugar level in diabetics: study By Will Dunham

WASHINGTON (Reuters) - Cutting down on caffeine could help people with the most common form of diabetes better control their blood sugar levels, researchers said on Monday.

Giving caffeine to a small group of people with type 2 diabetes caused their levels of the blood sugar glucose to rise through the day, especially after meals, researchers at Duke University Medical Center in Durham, North Carolina, found.

"Caffeine appears to disrupt glucose metabolism in a way that could be harmful to people with type-2 diabetes," James Lane, a Duke medical psychologist who led the study, said in a telephone interview.

The new findings seem to run counter to previous research regarding diabetes and caffeine. Earlier studies indicated that people who drank coffee had a reduced risk of type-2 diabetes, and those who drank the most coffee had the lowest risk.

The researchers used new technology -- a tiny glucose monitor embedded under the abdominal skin -- to monitor the glucose levels continuously in 10 people, average age 63.

Diabetes Study Partially Halted After Deaths By GINA KOLATA

For decades, researchers believed that if people with diabetes lowered their blood sugar to normal levels, they would no longer be at high risk of dying from heart disease. But a major federal study of more than 10,000 middle-aged and older people with Type 2 diabetes has found that lowering blood sugar actually increased their risk of death, researchers reported Wednesday.

Among the study participants who were randomly assigned to get their blood sugar levels to nearly normal, there were 54 more deaths than in the group whose levels were less rigidly controlled. The patients were in the study for an average of four years when investigators called a halt to the intensive blood sugar lowering and put all of them on the less intense regimen.

The results do not mean blood sugar is meaningless. Lowered blood sugar can protect against kidney disease, blindness and amputations, but the findings inject an element of uncertainty into what has been dogma — that the lower the blood sugar the better and that lowering blood sugar levels to normal saves lives.

Despite Risks, Vitamins Popular With Cancer Patients

Vitamin use is common among the nation’s 10 million cancer survivors, despite little evidence that supplements help and worries that some may actually fuel the disease.

Researchers at the Fred Hutchinson Cancer Research Center in Seattle reviewed 32 studies conducted between 1999 and 2006. The investigators found that 64 percent to 81 percent of cancer survivors overall reported taking extra vitamins or minerals (excluding multivitamins). In the general population, only 50 percent of American adults reported taking dietary supplements.

The findings, published this month in The Journal of Clinical Oncology and funded by the National Cancer Institute, are worrisome because little is known about how megadoses of vitamins affect cancer. Some lab studies have suggested that antioxidants can improve the effectiveness of cancer treatments. But many more studies raise questions about the use of these supplements. A 1995 report in The Journal of Biological Chemistry showed that cancer cells in a petri dish thrive in the presence of vitamin C.

The Sex of Your Surgeon May Matter

Whether a woman receives radiation treatment after breast cancer surgery may be influenced by the gender of her surgeon, according to a new report from The Journal of the National Cancer Institute.

The study, from researchers at Columbia University, set out to determine why breast cancer treatment still varies among similar patients. In particular, they looked at radiation treatment given to women after lumpectomy. The treatment is considered a standard of quality cancer care and has been shown to reduce breast cancer recurrence and mortality. However, many women still don’t receive it.

Women who received radiation were more likely to have a female surgeon. Women who were treated by more experienced surgeons were also more likely to receive radiation treatment, as were women treated by doctors trained in the United States.

Doctors use Wii games for rehab therapy By LINDSEY TANNER

CHICAGO - Some call it "Wiihabilitation." Nintendo's Wii video game system, whose popularity already extends beyond the teen gaming set, is fast becoming a craze in rehab therapy for patients recovering from strokes, broken bones, surgery and even combat injuries.

The usual stretching and lifting exercises that help the sick or injured regain strength can be painful, repetitive and downright boring.

In fact, many patients say PT — physical therapy's nickname — really stands for "pain and torture," said James Osborn, who oversees rehabilitation services at Herrin Hospital in southern Illinois.

Using the game console's unique, motion-sensitive controller, Wii games require body movements similar to traditional therapy exercises. But patients become so engrossed mentally they're almost oblivious to the rigor, Osborn said.
