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.

What factors seem to have the most influence? Continue Reading »

Learning can be incidental. We all memorize facts without paying much attention to these facts or without willing to memorize them. However, when one really wants to memorize a fact, it is crucial to pay attention. Many studies have shown that compared to full attention conditions, dividing attention during study time leads to poor memory performance.

This exercise will help you practice focusing your attention.

It may seem easy but make sure you count twice!

Yesterday, Lucy went all the way to Boston. She wanted to buy new shoes. She had to go in many shops before she found the shoes she wanted. She was happy to stop at a restaurant to have some tea and cookies before she took the train back home.

Last summer, Jean and Harriet spent their vacation in Michigan. They rented a cabin on the lake. The cabin had two bedrooms and a nice deck. They used to spend a lot of time on the deck, just looking at how the light would change on the water. Several times, they borrowed bikes from their neighbors and spent a few hours exploring the villages not far from their cabin.

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.

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 »

Study Questions Effectiveness Of $80 Million Per Year 'Brain Exercise Products Industry for Elderly (Science Daily)

- "There is much research on the benefits of cognitive rehabilitation strategies among elderly who already experience mild cognitive impairment (MCI) or Alzheimer's disease, as well as on the positive impact of physical exercise. The researchers, however, wanted to evaluate current research that would focus on the impact of cognitive interventions in the healthy elderly population."

- "...they concluded that there was no evidence indicating that structured cognitive intervention programs had an impact on the progression of dementia in the healthy elderly population"

Comment:  we have not reviewed the analysis yet, so cannot comment in depth. However, just from the press release, we see a few potential problems in how the study was framed, reducing its practical value: Continue Reading »

"We’ve all heard about dumbing down. But there is plenty of evidence that the opposite is also true. Is this, in fact, the age of mass intelligence?"

Fascinating article in Intelligent Life, a publication by The Economist:

THE AGE OF MASS INTELLIGENCE

- "Millions more people are going to museums, literary festivals and operas; millions more watch demanding television programmes or download serious-minded podcasts. Not all these activities count as mind-stretching, of course. Some are downright fluffy. But, says Donna Renney, the chief executive of the Cheltenham Festivals, audiences increasingly want “the buzz you get from working that little bit harder”. This is a dramatic yet often unrecognised development. “When people talk and write about culture,” says Ira Glass, the creator of the riveting public-radio show “This American Life”, “it’s apocalyptic. We tell ourselves that everything is in bad shape. But the opposite is true. There’s an abundance of really interesting things going on all around us.”

- "Third, what does all this say about the widespread view that societies are dumbing down, educational standards are crumbling and people’s ability to concentrate is collapsing? The reply must be that it cannot be true across the board and that for a significant number, the opposite is the case: people want more intellectually demanding things to see and hear, not fewer. Surely both things are happening at once: part of the population is dumbing down, part is wising up."

Landmark study just published: Basak C, et al "Can training in a real-time strategy video game attenuate cognitive decline in older adults?" Psychol Aging 2008; DOI: 10.1037/a0013494.

Playing computer games improves brain power of older adults, claim scientists (Telegraph)

- The team at the University of Illinois recruited 40 adults over 60 years old, half of whom were asked to play a computer game called Rise of Nations, a role-playing game in which you have to build your own empire.

- Game players have to build cities, feed and employ their people, maintain an adequate military and expand their territory.

- Both groups were assessed before, during and after the video game training on a variety of tests.

- As a group, the "gamers" became significantly better – and faster – at switching between tasks as compared to the comparison group. Their working memory, as reflected in the tests, was also significantly improved and their reasoning ability was enhanced.

- (Professor Art Kramer, an author of the study published in the journal Psychology & Aging) "This is one mode in which older people can stay mentally fit, cognitively fit. I'm not suggesting, however, that it's the only thing they should do."

Professor Kramer and I discussed this study last June during our conversation on Why We Need Walking Book Clubs:

Question (me): Tell us more about your work with cognitive training for older adults.

Answer (Prof Kramer): We have now a study in press where we evaluate the effect of a commercially available strategy videogame on older adults’ cognition.

Let me first give some context. It seems clear that, as we age, our Continue Reading »

A few weeks ago I had the pleasure to give a talk to one hundred or so staff members at New York Public Library. As you would expect, it was a very stimulating group, and one of the participants, Brigid Cahalan, just wrote a fun blog post on her impressions from the event:

Brain Fitness at New York Public Library:

- "After attending a recent staff training session offered by the library's Office of Staff Development, I decided to return to a habit of my childhood--eating sardines."
- key pillars for brain health ...are... "1) A balanced diet; 2) Cardiovascular physical exercise; 3) Stress management; and 4) Brain exercise: Novelty, Variety, Challenge (as long as it doesn't stress us out)."

Read full article: here.

Comment: A very interesting trend of observe - the growing role of public libraries in providing quality brain health information and even, why not, becoming community-based brain fitness destinations. After all, is it not mental stimulation of all sorts, incorporating Novelty, Variety, and Challenge, what they truly offer?
