SharpBrains

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."

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

Description: While most of us have heard the phrase “use it or lose it,” very few understand what “it” means, or how to properly “use it” in order to maintain brain function and fitness. The SharpBrains Guide to Brain Fitness is an invaluable guide that helps readers navigate growing brain research and identify the lifestyle factors and products that contribute to brain health and fitness. By gathering insights from eighteen of the world’s top scientists and offering tools and detailed descriptions of over twenty products, this book is an essential guide to the field of brain fitness, neuroplasticity and cognitive health. An accessible and thought-provoking read, The SharpBrains Guide to Brain Fitness educates lifelong learners and professionals in healthcare, education, business, etc., on emerging trends and forecasts of what the future will hold.

The growing field of cognitive training (one of the tools for brain fitness) can appear very confusing as the media keeps reporting contradictory claims. These claims are often based on press releases, without a deeper evaluation of the scientific evidence.

Let’s take a couple of recent examples, in successive days:

“It doesn’t work!” type of headline:
Reuters (Feb. 10, 2009) — Formal brain exercise won't help healthy seniors: research
“Healthy older people shouldn't bother spending money on computer games and websites promising to ward off mental decline, the author of a review of scientific evidence for the benefits of these "brain exercise" programs says”.

“It works!” type of headline:
ScienceDaily (Feb. 11, 2009) — Computer Exercises Improve Memory And Attention, Study Suggests
“According to the researchers, participants who used the Brain Fitness Program also scored as well as those ten years younger, on average, on memory and attention tests for which they did not train.”

So… does structured brain exercise / cognitive training work or not?

The problem may in fact reside in asking this very question in the first place, as Alvaro pointed out a while ago in his article “Alzheimer's Disease: too serious to play with headlines“.

We need a more nuanced set of questions.

Why? Because:
1. Cognition is made of several different abilities (working memory, attention, executive functions such as decision-making, etc)
2. Available training programs do not all train the same abilities
3. Users of training programs do not all have the same needs or goals
4. We need to differentiate between enhancing cognitive functions and delaying the onset of cognitive deficits such as Alzheimer’s.

Let’s illustrate these points, by Continue Reading »

As you may know, memory relies mostly on some temporal (in green) and frontal (in red) areas of the brain. These may be the areas that will get stimulated when you (assuming you are American or have lived in the US for long) try to remember the missing words in the American proverbs below.

However when it comes to internationals proverbs below you may have to use your reasoning skills more than your memory skills, as it is likely that you do not know these proverbs. In this case, the frontal exercise is more intense. Try to guess what the final words of each international proverb might be. Use your logical skills.

If you live outside the USA, your experience will probably be the reverse.

US proverbs

1. The early bird gets the ___________.
2. After all is _______ and done, more is said than __________.
3. From ___________ beginnings come great ____________. Continue Reading »

Learning & the Brain is a conference that gets marked on my calendar annually because I always return home having either been exposed to new information, or with a new perspective on an old topic. Last month’s conference in Cambridge, MA, themed Using Emotions Research to Enhance Learning & Achievement, was no exception. As with previous conferences, in addition to the many keynote sessions, I focused on the adult learning strand, since so much of my time is spent providing professional development for, and collaborating with adults. Here are five conference cues as they relate to education.

1. CHALLENGE YOURSELF WITH NEW LEARNING

Aaron Nelson stated that our memory starts to decline between ages twenty-five and thirty, or to phrase it a bit more positively, Sam Wang says our memory peaks around age thirty. On the other end of the age spectrum, according to Ken Kosik, there is unequivocal evidence that education protects against Alzheimer's. Both Nelson and Kosik mentioned the theory of cognitive reserve, which translates roughly to the more we learn, the more connections we create, and therefore the greater the neuronal buffer we have to draw upon as we age.

Elkhonon Goldberg, at last April's conference, stated that “as one ages, the domain of the novel shrinks, and the domain of what is known grows". He cautioned the audience to beware of being on mental autopilot. Thus, the goal is not to simply get better at doing more of the same. The type of learning that makes a difference consists specifically of new, novel challenges. The result of such engagement is that Continue Reading »

Dr. Andrew Newberg is an Associate Professor in the Department of Radiology and Psychiatry and Adjunct Assistant Professor in the Department of Religious Studies at the University of Pennsylvania. He has published a variety of neuroimaging studies related to aging and dementia. He has also researched the neurophysiological correlates of meditation, prayer, and how brain function is associated with mystical and religious experiences.

Dr. Newberg, thank you for being with us today. Can you please explain the source of your interests at the intersection of brain research and spirituality?

Since I was a kid, I had a keen interest in spiritual practice. I always wondered how spirituality and religion affect us, and over time I came to appreciate how science can help us explore and understand the world around us, including why we humans care about spiritual practices. This, of course, led me to be particularly interested in brain research.

During medical school I was particularly attracted by the problem of consciousness. I was fortunate to meet researcher Dr. Eugene D'Aquili in the early 1990s, who had been doing much research on religious practices effect on brain since the 1970s. Through him I came to see that brain imaging can provide a fascinating window into the brain.

Can we define religion and spirituality -which sound to me as very different brain processes-, and why learning about them may be helpful from a purely secular, scientific point of view?

Good point, definitions matter, since different people may be searching for God in different ways. I view being religious as participating in organized rituals and shared beliefs, such as going to church. Being spiritual, on the other hand, is more of an individual practice, whether we call it meditation, or relaxation, or prayer, aimed at expanding the self, developing a sense of oneness with the universe.

What is happening is that specific practices that have traditionally been associated with religious and spiritual contexts may also be very useful from a mainstream, secular, health point of view, beyond those contexts. Scientists are researching, for example, what Continue Reading »

Today's kids are into multi-tasking. This is the generation hooked on iPods, IM'ing, video games - not to mention TV! Many people in my generation think it is wonderful that kids can do all these things simultaneously and are impressed with their competence.

Well, as a teacher of such kids when they reach college, I am not impressed. College students these days have short attention spans and have trouble concentrating. They got this way in secondary school. I see this in the middle-school outreach program I help run. At this age kids are really wrapped up in multi-tasking―at the expense of focus.

According to a Kaiser Family Foundation study last year, school kids in all grades beyond the second grade committed, on average, more than six hours per day to TV or videos, music, video games, and computers. Almost one-third reported that "most of the time" they did their homework while chatting on the phone, surfing the Web, sending instant messages, watching TV, or listening to music.

Kids think that this entertainment while studying helps their learning. It probably does make learning less tedious, but it clearly makes learning less efficient and less effective. Multi-tasking violates everything we know about how memory works. Now we have objective scientific evidence that Continue Reading »

As the Brain Fitness industry continues to gain momentum, and people explore all the incredible brain-training tools being developed, we hope that enthusiasts don't take their eye off the importance of the physical health of the brain and all the systems it communicates with. The brain is unique in that it houses our cognitive and emotional capacities in the form of the mind. It is a 'cognitive' organ that hungers for stimulation from new experiences and challenges. Many brain fitness programs strive to satisfy this need. Yet the brain is also a physical organ that plays by many of the same rules as the heart, lungs, liver and kidneys. To stay healthy and perform optimally it requires quality nutrition, physical activity and optimal sleep. The brain, especially, relies on a healthy vascular system to efficiently deliver oxygen and key nutrients and remove waste. In fact, the brain uses approximately 20% of the oxygen we breathe to satisfy its high-energy demands. Given that the brain only weighs about 2% of the body, we can consider it an energy hog and we must cater to its needs very carefully.

Nutrients play key roles in brain function. Several have shown efficacy in clinical trials treating cases of mood disorders, cognitive decline and of course benefiting the physical health of the brain. Nutrients are both the raw materials employed in creating new neural connections and Continue Reading »

We just received this quote of how a major health system is using our Brain Fitness Market Report:

"At Sutter Health Partners we recognize the importance of brain health and how much the health of the brain and the body are interdependent.  The market report helped us further target our coaching efforts to integrate brain fitness and upgrade our entire coaching platform.  It is easy to read and gives you the industry perspective in a thorough yet concise manner.  I highly recommend it!"

-- Margaret Sabin, CEO of Sutter Health Partners and VP, New Product Development, at Sutter Health.

You may wonder, "what is the link between  wellness coaching and brain fitness"?

In practice, good health and wellness coaches provide excellent brain health advice, given that the areas they focus on (nutrition, physical exercise, stress management) do play an important role in maintaining our brains in top shape.

Additionally, pioneers  such as Sutter Health Partners are adding a Brain "lens" to their work. How?

First, by better understanding and explaining the brain benefits of what they already do, in order to provide additional motivation to stick with healthy behaviors. For example, most people will be able to recite multiple benefits of moderate cardiovascular exercise. But how many know  that it can also contribute to neurogenesis -the creation of new neurons - in adult brains?

Second, by starting to offer brain fitness guidelines to clients who want too go beyond crossword puzzles and sudoku.

I had a great training session with a number of Sutter Health coaches last week - let me summarize some of the main points we covered. Continue Reading »
