(Editor's Note: I recently came across an excellent book and resource, The Alzheimer's Alzheimer's Disease Action PlanAction Plan: The Experts' Guide to the Best Diagnosis and Treatment for Memory Problems, recently released in paperback. Dr. Murali Doraiswamy, one of the authors and leading Alzheimer's expert, kindly helped us create a 2-part article series to share with SharpBrains readers advice on a very important question, "How can we help the public at large to distinguish Alzheimer's Disease from normal aging --- so that an interest in early identification doesn't translate into unneeded worries?" What follows is an excerpt from the book, pages 72-78, discussing the Pros and Cons of the most common assessments).

---

While no single test (other than a brain biopsy, which is a very invasive and risky procedure) can conclusively prove that a person has Alzheimer’s, many tests can give us a good idea. A list of all the tests that help us assess memory and thinking problems appears at the end of this chapter. Meanwhile, let’s take a good look at the whys and hows of a thorough memory assessment.

WHAT A DIFFERENCE AN EXTRA TEST CAN MAKE

To understand why getting tested (and retested as symptoms change and the disease progresses) is important, check out the experience of Katherine, who went to the doctor complaining of a memory slowdown. She took five of the most important neuropsychological tests, which assess brain function without actually physically looking at the brain. Then she underwent brain scans, a cardiovascular workup, and blood tests to see what else was going on that might be undermining her mental function. Continue Reading »

Think about this: How can anyone take care of his or her brain when every week brings a new barrage of articles and studies which seem to contradict each other?

Do supplements improve memory? Do you need both physical and mental exercise –or is one of them enough? Which brain training approach, if any, is worth one's time and money?

We tried to address these questions, and many others, in our recent book, The SharpBrains Guide to Brain FitnessSharpBrains Guide to Brain Fitness. The Book (182 pages, $24.95), that we presented at Games for Health Conference last week. The book is the result of over two years of extensive research including more than a hundred interviews with scientists, professionals and consumers, and a deep review of the scientific literature, led by neuropsychologist Elkhonon Goldberg and myself with the help of cognitive scientist Pascale Michelon. As we wrote in the Introduction, what we wanted to do first of all was to debunks these 10 myths on brain health and brain training:

Myth 1. Genes determine the fate of our brains.
Facts: Lifelong neuroplasticity allows our lifestyles and actions to play a meaningful role in how our brains physically evolve, especially given longer life expectancy.

Myth 2. Aging means automatic decline.
Facts: There is nothing inherently fixed in the precise trajectory of how brain functions evolve as we age.

Myth 3. Medication is the main hope for cognitive enhancement.
Facts: Non-invasive interventions can have comparable and more durable effects, side effect-free.

Myth 4. We will soon have a Magic Pill or General Solution to solve all our cognitive challenges.
Facts: A multi-pronged approach is recommended, centered around nutrition, stress management, and both physical and mental exercise.

Myth 5. There is only one “it” in “Use It or Lose it”.
Facts: The brain is composed of a number of specialized units. Our life and productivity depend on a variety of brain functions, not just one.

Myth 6. All brain activities or exercises are equal.
Facts: Varied and targeted exercises are the necessary ingredients in brain training so that a wide range of brain functions can be stimulated.

Myth 7. There is only one way to train your brain.
Facts: Brain functions can be impacted in a number of ways: through meditation, cognitive therapy, cognitive training.

Myth 8. We all have something called “Brain Age”.
Facts: Brain age is a fiction. No two individuals have the same brain or expression of brain functions.

Myth 9. That “brain age” can be reversed by 10, 20, 30 years.
Facts: Brain training can improve specific brain functions, but, with research available today, cannot be said to roll back one’s “brain age” by a number of years.

Myth 10. All human brains need the same brain training.
Facts: As in physical fitness, users must ask themselves: What functions do I need to improve on? In what timeframe? What is my budget?

Do you have other myths in mind you would like  us to address?

We have started to receive great feedback from the healthcare community, such as this email from a neurosurgeon in Texas:

"I really like the book, it is comprehensive without being too technical. I have recommended it to several patients. There are some other books that I expected would be greeted with enthusiasm, but were too complex for most of my patients. I think this book is right in the sweet spot".

And this great book review by an Internist Physician and Robert Wood Johnson Foundation Fellow, titled Is Your Brain A Couch Potato?:

“…a short, sweet, entertaining read of a complex topic, with timely (written in 1/09) reviews of 21 top technology products, as well as informed and expert predictions of where this burgeoning brain-fitness field is headed. More importantly, after you read it, you'll have a good, detailed sense of where you, personally, can act to improve your own couch-potato brain - and how to keep it fit and flexible your whole life. The SharpBrains Guide To Brain Fitness reminds of us all why books (and not just googling a topic) can be well worth your time and money. Two Stethoscopes Up - check it out. life."

(Editor's Note: interviewing Richard Nisbett, author of the excellent Intelligence and How to Get Itrecent book Intelligence and How to Get It: Why Schools and Cultures Count, was in my To Do list. I then found that fellow blogger David DiSalvo was faster than I was and did a great job, so here we bring you David's interview and take).

While the debate over intelligence rages on many fronts, the battle over the importance of heredity rages loudest. It’s easy to see why. If the camp that argues intelligence is 75 to 85 percent genetically determined is correct, then we’re faced with some tough questions about the role of education. If intelligence is improved very little by schools, and if the IQ of the majority of the population will remain relatively unchanged no matter how well schools perform, then should school reform really be a priority?

More to the point, if our genes largely determine our IQ, which in turn underlies our performance throughout our lives, then what is the role of school? For some in this debate the answer to that question is simply, “to be the best you can be.” But that seems little comfort for those who aspire to “be” more than what their IQ category predicts they will.

Those on the other side of this debate question whether heredity plays as big a role as the strong hereditarians claim. And for the role it does play, they question whether hereditability implies immutability. Heredity of height, for example, is about 90 percent, and yet average height in several populations around the world has been steadily increasing due to non-genetic influences, like nutrition. If such a strong hereditary trait can be radically altered by environmental factors–and height is but one example of this–then why is intelligence different?

It is not, argues the camp that might best be described as intelligence optimists. For them, the pessimism that colors the strong hereditarian position isn’t only discouraging, it’s dangerous. Too much is hanging in the balance for pessimism about the potential of our children to prevail.

Richard NisbettRichard Nisbett is a champion of the intelligence optimist camp, and with his latest book, Intelligence and How to Get It: Why Schools and Cultures Count , he has emerged as the most persuasive voice marshalling evidence to disprove the heredity-is-destiny argument. Intellectual advancement, Nisbett argues, is not the result of hardwired genetic codes, but the province of controllable factors like schools and social environments–and as such, improving these factors is crucially important.

Longevity Dividend

Ever heard of the Longevity Dividend? Perhaps Grey is the New Gold: The Kronos Longevity Research Institute has released a new report summarizing the state of aging research that includes an excellent introduction into the Longevity Dividend, a "theory that says we hope to intervene scientifically to slow the aging process, which will also delay the onset of age-related diseases. Delaying aging just seven years would slash rates of conditions like cancer, diabetes, Alzheimer’s disease and heart disease in half." With that context in mind, is the National Institute on Aging getting its fair budget share?

Education & Learning

10% Students may have working memory problems: Why does this matter?: A recent study screened over 3,000 school-aged students in schools in the UK and found that 1 in 10 was identified as having working memory difficulties. Working memory is our ability to store and manipulate information for a brief time, and difficulties in this brain function may lead into difficulties in reading and mathematics. Dr. Tracy Alloway reviews the study and elaborates.

Brain Scientists Identify Links between Arts & Learning: Nicky Pentilla comments on a recent report sponsored by the Dana Foundation and a related Learning, Arts, and the Brain Summit. "Arts education influences learning and other areas of cognition and may deserve a more prominent place in schools." Of particular note is the finding that showed significant brain plasticity as a result of instrumental music instruction are repeated practice.

Brain-fitness games join workplace, as well as senior center, arsenals (MarketWatch)

- "Consumers and retirement homes have made brain-fitness games and exercises a commercial hit, but now some insurers and employers are incorporating them into wellness programs that promote health not just for the body but also for the mind."

- "Improving brain health can result in less presenteeism, the tendency to be at work but be distracted and not able to focus," he added. "If you look at disability costs, absenteeism and presenteeism account for most of the medical costs, and that's a good reason for employers to be focused on brain health." (according to Dr. Eugene Baker, vice president at OptumHealth's Behavioral Solutions division)"

The article reviews innovative practices at OptumHealth, Nationwide Auto Insurance Company, Humana, Penn Treaty American Corp, Allstate, and the US Army. I am glad to see the media start to notice the importance of cognitive assessments and the growing activity by insurers. Continue Reading »

The Longevity Dividend is a theory that says we hope to intervene scientifically to slow the aging process, which will also delay the onset of age-related diseases. Delaying aging just seven years would slash rates of conditions like cancer, diabetes, Alzheimer’s disease and heart disease in half. That’s the longevity part.

The dividend comes from the social, economic, and health bonuses that would then be available to spend on schools, energy, jobs, infrastructure—trillions of dollars that today we spend on healthcare services. In fact, at the rate we’re going, by the year 2020 one out of every $5 spent in this country will be spent on healthcare. Obviously, something has to change.

Enter the Longevity Dividend. The Longevity Dividend doesn’t suggest that we live longer; instead, it calls for living better. The idea is that if we use science to increase healthspan, not lifespan. In other words, tomorrow’s 50-year-old would have the health profile of a 43-year-old.

It might sound like science fiction, but, in fact, it’s quite possible. We’re already doing it in some animal models using genetic and dietary interventions, techniques related to what scientists call “the biology of aging.”

Getting there in humans, however, means embracing an entirely new approach to our thinking about disease and aging, and how we conduct scientific research into the two.

Getting Scientists’ Attention

A group of eminent researchers first proposed the Longevity Dividend in a 2006 article published in The Scientist. The authors, S. Jay Olshansky, PhD, professor of epidemiology and biostatics at the University of Illinois in Chicago, Daniel P. Perry, executive director of the Alliance for Aging Research in Washington, DC, Richard A. Miller, MD, PhD, professor of pathology at the University of Michigan in Ann Arbor, and Robert N. Butler, MD, president and CEO of the International Longevity Center in New York, intended their essay to be a “general statement to scientists” about the need for a paradigm shift in the way we think about aging and disease.

The researchers also met with U.S. senators who served on the Senate committee that oversaw the budget for the National Institutes of Health (NIH). “We told them we believed Continue Reading »

Arts education influences learning and other areas of cognition and may deserve a more prominent place in schools, according to a wave of recent neuroscience research.One recent study found that children who receive music instruction for just 15 months show strengthened connections in musically relevant brain areas and perform better on associated tasks, compared with students who do not learn an instrument.

A separate study found that children who receive training to improve their focus and attention perform better not only on attention tasks but also on intelligence tests. Some researchers suggest that arts training might similarly affect a wide range of cognitive domains. Educators and neuroscientists gathered recently in Baltimore and Washington, D.C., to discuss the increasingly detailed picture of how arts education changes the brain, and how to translate that research to education policy and the classroom. Many participants referred to the results of Dana Foundation-funded research by cognitive neuroscientists from seven leading universities over three years, released in 2008.

“Art must do something to the mind and brain. What is that? How would we be able to detect that?” asked Barry Gordon, a behavioral neurologist and cognitive neuroscientist at Johns Hopkins University, who spoke May 8 during the “Learning and the Brain” conference in Washington, D.C. “Art, I submit to you without absolute proof, can improve the power of our minds. However, this improvement is hard to detect.”

Study links music, brain changes

Among the scientists trying to detect such improvement, Ellen Winner, a professor of psychology at Boston College, and Gottfried Schlaug, a professor of neurology at Beth Israel Deaconess Medical Center and Harvard Medical School, presented research at the “Learning, Arts, and the Brain” summit May 6 in Baltimore. Their work measured, for the first time, changes to the brain as a result of music training.

For four years, Winner and Schlaug followed children ages 9 to 11, some of whom Continue Reading »
