Cognitive training (or structured mental exercise) definitely seems to work – as long as we define properly what “work” means, don’t expect magic cures, and help navigate options. Please keep reading…

Interview: Baycrest

Interview with Baycrest’s CEO Dr. William Reichman: Discussing the recent Centre for Brain Fitness at Baycrest, Dr. Reichman suggests that “we have an opportunity to make major progress in Brain Health in the XXI century, similar to what happened with Cardiovascular Health in the XXth, and technology will play a crucial role.” A major obstacle? We need a consensus on “widely accepted standards for outcome measures”.

Does It Work?

Does cognitive training work? (For Whom? For What?): 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 understanding of the scientific evidence. Dr. Pascale Michelon, SharpBrains’ Research Manager for Educational Initiatives, analyzes a couple of recent studies, clarifying what they mean – and what they don’t mean.

It Works, and It Doesn’t Work: the IMPACT study (a major, multi-site study on the Posit Science auditory program) will be published at the Journal of the American Geriatrics Society in April. Results support that cognitive training works – but doesn’t support the grandiose “brain age” claims we see too often.

Cognitive Training can Influence Brain Biochemistry: Dr. David Rabiner discusses a recent scientific study that “shows that brain biochemistry can be modified by experience”, and that computerized cognitive training (Cogmed working memory training) can provide that experience.

The Big Picture

Making Healthy Choices – Primare Care and Prevention: a panel at the recent World Economic Forum explored why “New markets and industries are arising – “silver industries” such as financial services, health, housing and hospitality geared to senior citizens. Longevity needs to be linked to health – including cognitive health – and lifestyle choices play a major role in health.”

Enrich your environment now and benefit your future offspring: Dr. Robert Sylwester reports that “all sorts of long held-beliefs about our brain and cognition are being re- examined by cognitive neuroscientists” because of fascinating studies such as the one  he reviews (with mice): “The study’s findings seemed to suggest that acquired characteristics can be genetically transmitted…long-term benefits accrue from a stimulating early environment that encourages curiosity and exploration.”

Managing Emotions

From Distress to De-Stress: helping anxious, worried kids: In a detailed 2-part article, (Part 1, Part 2), Dr. Jerome Schultz provides great tips on how to help children learn to self-regulate emotions, adding that “Teachers, occupational therapists, physical education teachers and parents need to actually teach children (of all ages) how to get themselves into a physical state of being relaxed. This doesn’t happen automatically. If it did, there wouldn’t be so many adult yoga classes!”

Lie to Me, Paul Ekman and Biofeedback: You may have watched the new series Lie To Me, with Tim Roth, based on the work of Paul Ekman. The introduction to the second episode shows why what are called “lie detectors” are nothing but biofeedback systems that measure physiological anxiety.

The IMPACT study which we reported on in December 2007, funded by Posit Science, conducted  by the Mayo Clinic and USC Davis, has just announced publication at the Journal of the American Geriatrics Society. Reference:

Computer Exercises Improve Memory And Attention, Study Suggests (Science Daily)

- “The Improvement in Memory with Plasticity-based Adaptive Cognitive Training (IMPACT) study was funded by the Posit Science Corporation, which owns the rights to the Brain Fitness Program, tested in the study.”

- “Of the 487 healthy adults over the age of 65 who participated in a randomized controlled trial, half used the Brain Fitness Program for 40 hours over the course of eight weeks. The Brain Fitness Program consists of six audio exercises done on a computer, and is intended to “retrain the brain to discriminate fine distinctions in sound, and do it in a way that keeps the user engaged,” Zelinski explained.” The other half of participants spent an equal amount of time learning from educational DVDs followed by quizzes.

Comment: this is a very interesting study, in that it shows both that cognitive training works, and that it doesn’t work.

Concussion effect ’spans decades’ (BBC)

- “People concussed in their youth show subtle signs of mental and physical problems even more than 30 years later, say Canadian researchers.”

- “Dr Louis de Beaumont, who led the study, said: “This study shows that the effects of sports concussions in early adulthood persist beyond 30 years post-concussion, and that it can cause cognitive and motor function alterations as the athletes age.”

- “Athletes should be better informed about the cumulative and persistent effects of sports concussion on mental and physical processes so they know about the risk associated with returning to their sport.”

Given the importance of this topic, which we covered in our 2008 Market Research, we are happy to read about new resources like a new book titled Sports Neuropsychology: Assessment and Management of Traumatic Brain Injury

From a recent book review by Gary S. Solomon, Ph.D.:

Sharon Begley, Newsweek’s science reporter, recently wrote that

- “With the nation’s 78 million baby boomers approaching the age of those dreaded “where did I leave my keys?” moments, it’s no wonder the market for computer-based brain training has shot up from essentially zero in 2005 to $80 million this year, according to the consulting firm SharpBrains.”

- “Now comes the largest and most rigorous study of a commercially-available training program, and it shows that there is hope for aging brains. This morning, at the meeting of the Gerontological Society of America, scientists are presenting data showing that after eight weeks of daily one-hour sessions with Brain Fitness 2.0 from Posit Science, elderly volunteers got measurably better in their brain’s speed and accuracy of processing. “

We recently had the chance to interview Dr. Elizabeth Zelinski of the University of Southern California Andrus Gerontology Center, who led the IMPACT (Improvement in Memory with Plasticity-based Adaptive Cognitive Training) Study Sharon Begley refers to in the quote above. 

First, some context on this study, which is by far the largest high-quality study of its kind. The study was prospective, randomized, controlled, and used a double blind trial. 524 healthy adults 65-year-old and over were divided into two groups. One received an hour a day of training for eight to ten weeks, and the other spent the same amount of time watching educational DVDs. The IMPACT study, funded by Posit Science corporation, was performed in multiple locations, including the Mayo Clinic, USCF, and San Francisco Veteran Affairs Medical Center.

The discussion centers at his point on the initial results that were presented Gerontological Society of America (the study hasn’t been published yet).

Alvaro Fernandez: Dr. Zelinski. Thank you for being with us. Could you start by setting the context and providing an overview of how human cognitive abilities typically evolve as we age – based on insights from your Long Beach Longitudinal Study?

Elizabeth Zelinski: Of course. The first concept to understand is that different cognitive skills evolve over the lifespan in different ways. Some that rely on experience, such as vocabulary, actually improve as we age. Some tend to decline gradually, starting in our late 20s. This happens, for example, with processing speed (how long it takes us to process and respond to information), memory, and reasoning. We could summarize this phenomenon by saying that as we age we get better at dealing with the familiar, but worse at dealing with the new. We can always learn, but at a slower pace.

Are there any specific tipping or inflection points in this trend, any age when the rate of decline is more pronounced?

We don’t have a clear answer to that. It depends a lot on the individual. In general it is a gradual, cumulative process, so that by age 70 we statistically see clear age declines. Which, for example, is a strong factor determining why older adults struggle to adapt to new technologies, but why trying to learn them provides needed mental stimulation. Now we know that genes only account for a portion of this decline. Much of it depends on our environment, lifestyle and actions.

Can you summarize what a healthy individual can do to slow down this process of decline, and help stay healthy and productive as long as possible?

One general recommendation is to do everything we can to prevent or delay disease processes, such as diabetes or high-blood pressure, that have a negative effect on our brains. For example, it is a tragedy in our society that we usually reduce our levels of physical exercise drastically after we leave school.

Let me then ask: what are the relative virtues of physical vs. mental exercise?

Great question! That in fact leads into my second recommendation. Aerobic exercise has been shown to Read the rest of this entry »
