The July/ August 2009 issue of The Journal on Active Aging includes my article Why We Need to Retool “Use It Or Lose It”

An excerpt:

“By now you have probably heard about brain plasticity, 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 improve the health and level of functioning of our brains, no matter our age.

Of particular importance to maintaining cognitive functioning through life are the hippocampus (deep inside the brain, part of what is called the limbic system), which plays a role in learning and memory; and the frontal lobes (behind your forehead), which are key to maintaining decision-making and autonomy. Is there a way to physically protect these parts of the aging brain? Yes. But the right answer is far from “do one more crossword puzzle” or “do more X” (whatever X is). The key is to add significantly different activities to ensure a flow of novelty, variety and challenge, combining physical and mental exercise while not ignoring factors such as stress management and balanced nutrition.

We need, in other words, to retool our understanding and practice of “Use it or lose it.” We must focus on the importance of getting out of our physical and mental routines and activities to get the benefits of real exercise—physical and mental.”

If you subscribe to our monthly newsletter, you may remember we ran a survey in January. Well, the response rate and the quality of the responses were nothing short of spectacular, in many dimensions. The responses from over 2,000 participants (out of 21,000 subscribers) reinforce the need for public awareness initiatives and quality information to help evaluate and navigate product claims.

I have been presenting the results from one of the questions (see below), yesterday at the ASA/ NCOA (American Society on Aging) event, today at IHRSA (International Health, Racquet and Sportsclub Association), as part of more comprehensive presentations of what is going on in the brain fitness and cognitive health field.

An obvious implication for the survey result reinforces the need for brain-related public awareness campaigns such as the ongoing Brain Awareness Week. Every year, landmark research findings open new opportunities to help maintain lifelong cognitive health and brain fitness. The opportunity is immense – but we will need to ensure the marketplace matures in a rational and sustainable manner, helping consumers and professionals separate hope from hype and make informed decisions.

Robin Klaus, Chairman of Club One Fitness Centers (the company is a client, he is an advisor), just gave us a nice quote saying that “as our population ages the fields of physical fitness and brain fitness will naturally merge and, as this happens, a whole new field of valued added services will emerge for our members. High quality informational resources such as SharpBrains’ are crucial to the success of this merger.”

The Survey: Results to Key Question 

Asked, “What is the most important problem you see in the brain fitness field and how do you think it can be solved?” respondents identified the following six problems in rank order:

#1: Public Awareness (39%)
- “Getting people to understand that heredity alone does not decide brain functioning.”
- “An expectant public will first want to believe that a “miracle” drug is to be soon available (to prevent Alzheimer’s Disease).”

#2: Navigating Claims (21%)
- “How to separate marketing hype from stuff that really works?”
- “The lack of standards and clear definitions is very confusing, and makes a lot of people sceptical.”

#3: Research (15%)
- “Determining what activities are most beneficial to Read the rest of this entry »

We have talked about the value of meditation before (see Mindfulness and Meditation in Schools), as a form of well-directed mental exercise than can help train attention and emotional self-regulation.  Which other studies have shown how it strengthens specific parts of the brain, mainly in the frontal lobe.

Dr. Rabiner shares with us, below, an excellent review of a new study that analyzes the benefits of mindfulness for adolescents and adults with attention deficits. He writes that “although this is clearly a preliminary study, the results are both interesting and encouraging.”

Does Mindfulness Meditation Help Adults & Teens with ADHD

– By Dr. David Rabiner

Although medication treatment is effective for many individuals with ADHD, including adolescents adults, there remains an understandable need to explore and develop interventions that can complement or even substitute for medication. This is true for a variety of reasons including:
1) Not all adults with ADHD benefit from medication.
2) Among those who benefit, many have residual difficulties that need to be addressed via other means.
3) Some adults with ADHD experience adverse effects that prevent them from remaining on medication.

We human beings are social animals. It seems intuitive (even for introverts!) that social contact has benefits. Obviously we need other people to fulfill basic needs such making sure that our genes outlive. Maybe less obviously we seem to need other people to maintain adequate levels of mental well being and motivation.

Even less obviously, social contact may help us improve our brain functions…

Mental fitness seems to depend on a large part on being connected with other people. For instance people with low social support seem to be more prone to mental illness (McGuire & Raleigh, 1986). In 2007, Gladstone and colleagues studied 218 patients with major depression and found out that low social support, especially coming from the family, was associated with chronic depression.

Merely imagining loneliness can negatively affect our behavior…

A CDC report estimated that, in 2003, 4.4 million youth ages 4-17 lived with diagnosed ADHD, and 2.5 million of them were receiving medication treatment. Now, which is the core deficit underlying ADHD-so that treatments really address it? and how are ADHD and brain development related? Keep reading…

ADHD & the Nature of Self-Control – Revisiting Barkley’s Theory of ADHD

— By David Rabiner, Ph.D

As implied in the title of his book, ADHD and the Nature of Self-Control, Dr. Barkley argues that the fundamental deficit in individuals with ADHD is one of self-control, and that problems with attention are a secondary characteristic of the disorder.

Dr. Barkley emphasizes that during the course of development, control over a child’s behavior gradually shifts from external sources to being increasingly governed by internal rules and standards. Controlling one’s behavior by internal rules and standards is what is meant by the term “self-control”.

Today we are fortunate to interview Dr. Jerri Edwards, an Associate Professor at University of South Florida’s School of Aging Studies and Co-Investigator of the influencial ACTIVE study. Dr. Edwards was trained by Dr. Karlene K. Ball, and her research is aimed toward discovering how cognitive abilities can be maintained and even enhanced with advancing age.

Main focus of research

Alvaro Fernandez: Please explain to our readers your main research areas

Jerri Edwards: I am particularly interested in how cognitive interventions may help older adults to avoid or at least delay functional difficulties and thereby maintain their independence longer. Much of my work has focused on the functional ability of driving including assessing driving fitness among older adults and remediation of cognitive decline that results in driving difficulties.

Some research questions that interest me include, how can we maintain healthier lives longer? How can training improve cognitive abilities, both to improve those abilities and also to slow-down, or delay, cognitive decline? The specific cognitive ability that I have studied the most is processing speed, which is one of the cognitive skills that decline early on as we age.

ACTIVE results

Can you explain what cognitive processing speed is, and why it is relevant to our daily lives?

Processing speed is mental quickness. Just like a computer with a 486 processor can do a lot of the same things as a computer with a Pentium 4 processor, but it takes much longer, our minds tend to slow down with age as compared to when we were younger. We can do the same tasks, but it takes more time. Quick speed of processing is important for Read the rest of this entry »

Neurofeedback is one of the technologies that people often ask us about.  It is a promising intervention in a variety of areas, and has got significant traction in helping kids with ADD/ ADHD. Now, given the significant cost it poses for parents, we need to ask the question: “How Strong is the Research Support for Neurofeedback Treatment of Children with ADHD”?

We are honored to present the thoughts of Duke University’s Dr. David Rabiner, a leading authority on the field, on that important issue. As a bonus, you will enjoy his detailed description and suggestions of how to design a high-quality scientific study. Without further ado, let’s hear Dr. Rabiner speak.

(Update as of March 2009: Dr. David Rabiner has written an update to the article below based on a newer study. You can read it clicking on link: New Study Supports Neurofeedback Treatment for ADHD)

How Strong is the Research Support for Neurofeedback Treatment of Children with ADHD? 

Neither of the two prominent approaches to treating ADHD – medication treatment and behavior therapy – are expected to effect long term changes in the child. Medication treatment induces short-term changes in brain activity that is associated with a reduction in symptoms for many individuals. Behavior therapy attempts to create a set of environmental contingencies that promote desired behavior in the child, but which is unlikely to endure when those contingencies are removed.

In recent years, researchers have begun devoting greater attention to the possibility that children – and adults – may be provided with particular kinds of experiences that may induce alterations in brain functioning that are associated with more enduring changes, i.e., they do not dissipate as soon as treatment ends.

Neurofeedback – also known as EEG Biofeedback – is reflective of this approach and has a history that goes back Read the rest of this entry »

Did you read about the recent experiment where young chimps displayed amazing visual working memory capability, beating humans?

- You can watch a short video here.

- Lumos Labs has released a very fun game to test your own skills: try out this Chimp Game!

 

Also, some very good recent news articles:

1) Is it worth going to the mind gym? (New Scientist). This is one of the best articles we have read in a while (unfortunately requires subscription).

- “Birdwatching is the brainchild of San Francisco-based Lumos Labs, just one of the dozens of companies that have sprung up in recent months to cash in on the “brain-training” craze. Like most of its competitors, the theory behind …”

Comments: the article introduces readers to much of the research and scientists we discuss in our blog, such as Torkel Klingberg’s work and recent results from the IMPACT study. The article would have been even better had Daniel Gopher been interviewed on his work improving cognitive performance of military pilots and basketball players.

2) Innovation: Your Brain Needs Just as Much Exercise as Your Body (Fox Business Network)

- “The market, however, is still small. According to Alvaro Fernandez , who co-founded market research and consulting firm SharpBrains, which is focused solely on the field of brain fitness, in 2007 the market was valued at $225 million, which is up from $150 million in 2005. Fernandez thinks there’s potential for it to surge, reaching more than $2 billion by 2016.”

Comments:  Very good article. Those estimates refer to the whole brain fitness software market to assess and train cognitive skills, including Read the rest of this entry »

Mark Katz, a San Diego clinical psychologist with decades of experience helping ADD/ ADHD kids and adults, and former Board Member of CHADD, and I had a very good meeting with a few school superintendents on Saturday.

We discussed the research state-of-the-art, current ADD/ ADHD interventions and the future of prevention-driven interventions.

Some highlights from our talk:

- More and more researchers are coming to see that the label “Attention deficit” was probably not the most fortunate one. Kids and adults with ADD/ ADHD can pay attention, when they are engaged in certain tasks, so the underlying problem is not a deficit of attention.

- ADD/ ADHD is not a problem of knowing, but a problem of doing. The bottleneck may reside in executive functions such as so-called working memory. The problem is execution, internalized behavior, not conceptual knowledge.

- For more information on Executive functions, you can check the excellent review in the American Journal of Psychiatry, of Dr. Elkhonon Goldberg’s book The Executive Brain

- Working memory is the ability to hold different things on line and manipulate them in real time in order to solve a problem, complete a task…

- When asked if “working memory” and “short-term memory” are the same, Mark explained that they refer to similar concepts, if not the same, but that researchers stopped using the term “short-term” memory many years ago, to make it clear that it is an active, not passive, skill.  In fact, he added, maybe it should be called “working attention” rather than “working memory”.

- We discussed the fortunate trend that many schools are migrating towards a public health model in helping kids with learning disabilities and ADD/ ADHD, focusing on more prevention at early ages than on reactive interventions to major problems.

- Working memory can be trained by intensive and targeted Brain Fitness Programs supported by the use of computer-based programs, like RoboMemo, the program that I came to know last year after a great Scientific American article that mentioned their clinical study with kids with ADD/ ADHD, published in the Journal of Child and Adolescent Psychiatry (See research here).
