Here you have the October edition of our monthly newsletter covering cognitive health and brain fitness topics. Please remember that you can subscribe to receive this Newsletter by email, using the box at the top of this page.

We recently run an online survey among subscribers of our monthly eNewsletter, and over 500 people said we have helped them make better personal or professional decisions on how to maintain and improve brain fitness. Most gave very illuminating examples, which we are reading and enjoying as we speak.

Respondents also had many good questions to ask, so I have selected 15 common ones, paraphrased/ synthesized them below, and answered them by linking to our most relevant posts and resources. I hope you enjoy the FAQ session.

Q: I teach a brain fitness class at my library/ senior center/ school, using much of your info. Can you share some of your presentations?
A: Yes, we have just decided to share, using a Creative Commons Attribution No Derivatives License, the full presentation of my recent book talk at New York Public Library. As long as you give credit to SharpBrains and don’t modify it, you are free to use the presentation you can see and download HERE. The talk was videotaped, and will be available online soon, so please keep tuned.

Q: What exactly does neuroplasticity mean, and why is it so important for education and health?
A: Start by reading how learning changes your brain.

Q. Is this only relevant for older adults? Can I also apply it in the workplace (I am 47)
A. I strongly suspect you do have a human brain, so you may benefit from these Ten Habits of Highly Effective Brains. Further, HR departments would do well to start paying more attention to Cognitive Fitness and the Mature Workforce trends.

Q. I read so many conflicting things I don’t know where to start.
A. You are not alone. We should all be aware that It is Not Only Cars That Deserve Good Maintenance: Brain Care 101.

Q. How can my organization deliver brain fitness activities as a community service?
A. These articles will provide good guidelines and ideas: Retooling Use It or Lose It , and Public Libraries: Community-Based Health Clubs for the Brain.

Q. Everyone seems obsessed with brain games. What about meditation?
A. Check out Yes, You Can Build Willpower, and Mindfulness Meditation in Schools.

Q. Are software-based cognitive interventions effective?
A. As a category, it certainly seems so, as long as we ask the right questions, For Whom, For What?. For example, did you see this Science paper on how Cognitive Training Can Influence Dopamine System?.

Q. What about the trade-off between time invested vs benefits realized.
A. Efficiency and replicability of cognitive and brain-based outcomes seem to be, in fact, the strongest points of structured cognitive interventions. They seem to maximize the Cognitive Value of your Mental Workout.

Q. It sometimes looks like the whole field came out of nowhere, due to Nintendo Brain Age’s success, so we can’t be talking about something serious.
A: Nintendo did indeed create consumer awareness (for a product with little evidence) but “brain training” has solid roots in neuropsychology and cognitive neuroscience, as you can read in our interview with Elkhonon Goldberg.

Q. What about neurofeedback?
A. After years of much clinical use and little solid evidence, several important trials have been published in 2009, showing how neurofeedback can help diagnose and treat ADHD patients.

Q. How can one improve memory?
A. Well, the answer deserves a whole book, but we can offer some Tips to Improve Memory including Sleep, Practice and Testing.

Q. How can I choose one among the number of products making memory and brain claims?
A. We suggest you use this Evaluation checklist, and consider reading our consumer guide/ book.

Q. Any general tips for educators and lifelong learners?
A. Indeed, here you have these 10 Brain Tips to Teach and Learn.

Q. How can I keep track of all the new trends, companies and products? Our health system/ insurer/ senior community/ venture firm/ company needs to make good decisions.
A. Well, that’s why we publish market research, such as the one summarized in this Infographic: State of the Market 2009 and also recently launched a professional Network for Brain Fitness Innovation. You can also Save the Date for the upcoming SharpBrains Summit.

Q: Thank you for all the information you provide…but what I want more of is… brain teasers!
A. Understood. We will make sure to offer more, but you can try, right now, these Top 50 Brain Teasers and continue with more recent puzzles and brain games.

Excellent Scientific American cover story:

Turbocharging the Brain–Pills to Make You Smarter?

“Will a pill at breakfast improve concentration and memory—and will it do so without long-term detriment to your health?”

Their answer, in short: not really, not anytime soon.

I couldn’t agree more. Let’s pay real attention to non-invasive options to augment cognition, from exercise to cognitive training and meditation.

For more context, you may enjoy my recent article Preparing Society for the Cognitive Age, published in Frontiers in Neuroscience.

In a recently published scientific study (see Hall C, et al “Cognitive activities delay onset of memory decline in persons who develop dementia” Neurology 2009; 73: 356-361), Hall and colleagues examined how education and stimulating activities may interact to contribute to cognitive reserve. The study involved 488 initially healthy people, average age 79, who enrolled in the Bronx Aging Study between 1980 and 1983. These individuals were followed for 5 years with assessments every 12 to 18 months (starting in 1980). At the start of the study, all participants were asked how many cognitive activities (reading, writing, crossword puzzles, board or card games, group discussions, or playing music) they participated in and for how many days a week. Researchers were able to evaluate the impact of self-reported participation these activities on the onset of accelerated memory decline in 101 individuals who developed dementia during the study.

Results showed that for every “activity day” (participation in one activity for one day a week) the subjects engaged in, they delayed for about two months the onset of rapid memory loss associated with dementia. Interestingly, the positive effect of brain-stimulating activities in this study appeared to be independent of a person’s level of education.

This is great news as it suggests that it is never too late to try to build up brain reserve. The more brain stimulating activities one does and the more often, the better for a stronger cognitive reserve.

The cognitive reserve hypothesis suggests that individuals with more cognitive reserve can experience more Alzheimer’s disease pathology in the brain (more plaques and tangles) without developing Alzheimer’s disease symptoms.

How does that work? Scientists are not sure but two possibilities are considered.
1. One is that more cognitive reserve means more brain reserve, that is more neurons and connections between neurons.
2. Another possibility is that more cognitive reserve means more compensatory processes (see my previous post “Education builds Cognitive Reserve for Alzheimers Disease Protection” for more details.)

Now, one may wonder about the difference types of mental stimulation available, including not only puzzles and such, but structured activities such as brain fitness software and meditation. Do we exercise our brain every time we think about something? What can one do to exercise one’s brain in ways that enhance capacity? Does aerobic fitness training also exercise one’s brain? What types of methodologies and products are available? Do they “work”? Are all the same?

Those are the types of questions we wanted to address in the book The SharpBrains Guide To Brain Fitness (available via Amazon.com). We are proud of the recognition the book has started to obtain, including endorsements by leading scientists:

“The SharpBrains Guide to Brain Fitness is the only book that I know of that seamlessly integrates latest information about cognitive health across the lifespan, with interviews with active researchers examining cognitive maintenance and enhancement, along with reviews of commercial products targeted to cognitive enhancement. The book should be very useful to anyone interested in brain care, both health care professionals and the public at large”.
– Arthur Kramer, Professor of Psychology at University of Illinois

“This SharpBrains book provides a very valuable service to a wide community interested in learning and brain topics. I found it interesting and helpful”
- Michael Posner, Emeritus Professor of Neuroscience at the University of Oregon, and first recipient of the Dogan Prize

– Pascale Michelon, Ph. D., is SharpBrains’ Research Manager for Educational Projects. Dr. Michelon has a Ph.D. in Cognitive Psychology and has worked as a Research Scientist at Washington University in Saint Louis, in the Psychology Department. She conducted several research projects to understand how the brain makes use of visual information and memorizes facts. She is now an Adjunct Faculty at Washington University.

Yes, You Can:

New research suggests we can build our willpower

– By Daniel Goleman

Those of us who struggle to resist junk foods or otherwise suffer a lack of willpower will be heartened by some good news from neuroscience. But there’s some bad news, too.

First, the bad news. A slew of studies suggest that we each have a fixed neural reservoir of willpower, and that if we use it on one thing, we have less for others. Tasks that demand some self-control make it harder for us to do the next thing that takes willpower.

In a typical experiment on this effect, one group of people was made to watch a video of a boring scene; another was not. Then both groups had to circle every “e” in a long passage of writing. The result? The people who had to first sit through the boring video gave up faster. The same loss of persistence has been found when people try to resist tempting foods, suppress emotional reactions, or even make the effort to try to impress someone.

This all suggests we have a fixed willpower budget, one we should be careful in spending. Some neuroscientists suspect that self-control consumes blood sugar, which takes a while to build up again; thus, the depletion effect.

But the good news is that we can grow our willpower; like a muscle, the more we use it, the more it gradually increases over time. But doing this takes, of all things, willpower.

As the muscle of will grows, the larger our reservoir of self-discipline becomes. So people who are able to Read the rest of this entry »

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 Fitness (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.”

—Doc Gurley, book review for SFGate.com (06/08/09)

The book:  The SharpBrains Guide to Brain Fitness (available via Amazon.com Here, review copies available upon request).

You may be reading all about brain fitness and brain training. It seems every week brings a new barrage of articles and studies which often contradict what you read the month before: Does Gingko Biloba help delay Alzheimer’s Disease? Can physical exercise help you stay sharp as you age? Which computer-based “brain fitness programs”, if any, are worth your money?

All this coverage reflects very exciting scientific findings but also poses a key dilemma: How to become an informed lifelong learner and consumer when there are few and contradictory authoritative guidelines?

The SharpBrains Guide to Brain Fitness (to be published in May 2009; $24.95) aims to fill that void. This guide is the result of over a year of extensive research including more than a hundred interviews with scientists, professionals and consumers, and a deep literature review. Below you have some of the main findings from our effort. The guide not only covers these aspects in more depth and offers practical guidance, but also includes 18 interviews with prominent scientists to help you understand the research better.

Can we introduce you to your Brain?

The Guide will start at the obvious starting point: The Human Brain. In order to make informed decisions about brain health, one needs to first understand the basic organization of the human brain and how it tends to change as we get older.

• The brain is composed of a number of regions serving distinct functions. Forget IQ: our life and productivity depend on a variety of brain functions, not just one.

• There is nothing inherently fixed in the trajectory of how brain functions evolve as we age. Your lifestyle, actions, and even thoughts, do matter.

The 4 Pillars of Brain Maintenance

Neuroplasticity is the lifelong capacity of the brain to change and rewire itself in response to the stimulation of learning and experience. The latest scientific research shows that specific lifestyles and actions can, no matter our age, improve the health and level of functioning of our brains.

At a time when educators are preoccupied with standards, testing, and the bottom line, some researchers suggest the arts can boost students’ test scores; others aren’t convinced. Karin Evans asks, What are the arts good for?

—
When poet and national endowment for the Arts Chairman Dana Gioia gave the 2007 Commencement Address at Stanford University, he used the occasion to deliver an impassioned argument for the value of the arts and arts education.

“Art is an irreplaceable way of understanding and expressing the world,” said Gioia. “There are some truths about life that can be expressed only as stories, or songs, or images. Art delights, instructs, consoles. It educates our emotions.”

For years, arts advocates like Gioia have been making similar pleas, stressing the intangible benefits of the arts at a time when many Americans are preoccupied with a market–driven culture of entertainment, and schools are consumed with meeting federal standards. Art brings joy, these advocates say, or it evokes our humanity, or, in the words of my 10–year–old daughter, “It cools kids down after all the other hard stuff they have to think about.”

Bolstering the case for the arts has become increasingly necessary in recent years, as school budget cuts and the move toward standardized testing have profoundly threatened the role of the arts in schools. Under the No Child Left Behind Act, passed in 2002, the federal government started assessing school districts by their students’ scores on reading and mathematics tests.

As a result, according to a study by the Center on Education Policy, school districts across the United States increased the time they devoted to tested subjects—reading/language arts and math—while cutting spending on non–tested subjects such as the visual arts and music. The more a school fell behind, by NCLB standards, the more time and money was devoted to those tested subjects, with less going to the arts. The National Education Association has reported that the cuts fall hardest on schools with high numbers of minority children.

And the situation is likely to worsen as state budgets get even tighter. Already, in a round of federal education cuts for 2006 and 2007, arts education nationally was slashed by $35 million. In 2008, the New York City Department of Education’s annual study of Read the rest of this entry »

Here you have the presentation I delivered on Tuesday at ETech 2009 (this year’s O’Reilly Emerging Technology Conference):

Emerging Research and Technology for Life Hacking/ Brain Training

(click to open presentation in new window)

Description: Life hacking. Brain training. They are one and the same. The brain’s frontal lobes enable our goal-oriented behavior, supporting “executive functions,” such as decision-making, attention, emotional self-regulation, goal-setting, and working memory. These functions can be enhanced with targeted practice – such as life hacking. This session will provide an overview of the cognitive neuroscience underpinning life hacking, and review the state-of-the-art of non-invasive tools for brain training: neurofeedback, biofeedback, software applications, cognitive simulations, Transcranial Magnetic Stimulation, and plain-old meditation.

It was great to meet fellow bloggers and presenters, such as Shelley Batts of Of Two Minds and Chris Patil of Ouroboros, and very inquisite and throughful audience members. Getting ready to speak at ASA/ NCOA and IHRSA next week!

Today we continue the conversation with Maggie Jackson, author of Distracted: The Erosion of Attention and the Coming Dark Age.

You can read part 1 here.

Q – In your Harvard Management Update interview, you said that “When what we pay attention to is driven by the last email we received, the trivial and the crucial occupy the same plane.” As well, it seems to be that a problem is our culture’s over-idealization of “always on” and “road warrior” habits, which distract from the importance of executive functions such as paying attention to one’s environment, setting up goals and plans, executing on them, measuring results, and internalizing learning. How can companies better equip their employees for future success? Can you offer some examples of companies who have positive cultures that encourage and reward employees fully put their frontal lobes into good use?

A – As I mentioned above, we are working and living in ways that undermine our ability to strategize, focus, reflect, innovate. Skimming, multitasking and speed all have a place in 21st-century life. But we can’t let go of deeper skills of focus and thinking and relating, or we’ll create a society of misunderstanding and shallow thinking.

To create workplaces that foster strategic thinking, deep social connection and innovation, we need to take three steps:

First, question the values that venerate McThinking and undermine attention. Recently, my morning paper carried a front-page story about efforts “in an age of impatience” to create a quick-boot computer. “It’s ridiculous to ask people to wait a couple of minutes to start up their computer,” explained one tech executive. The first hand up in the classroom, the hyper business-man or –woman who can’t sit still, much less listen – these are icons of success in American society. Still, many of us are beginning to question our adoration of instant gratification and hyper-mobility.

Second, we need to set the stage for focus individually and collectively by rewriting our climate of distraction and inattention. To help, some companies and business leaders are experimenting with “white space” – the creation of physical spaces or times on the calendar for uninterrupted, unwired thinking and Read the rest of this entry »
