SharpBrains

As mentioned before, the World Economic Forum asked me to write "an 800 words summary of your most compelling actionable idea on the challenges of gerontology", in preparation for the Inaugural Summit of the Global Agenda that will take place November 7 to 9th in Dubai.A good number of SharpBrains readers and clients offered their insights - and expressed an interest in reading the draft. So below you have - a proposal to create a Global Consortium for Neurocognitive Fitness Innovation, building on our existing market research and advisory services work. Your thoughts?

The Context

Growing Demands on Our Brains: Picture 6.7 billion Primitive Brains inhabiting a Knowledge Society where lifelong learning and mastering constant change in complex environments are critical for productive work, health and personal fulfillment.

Welcome to Planet Earth, 2008.

Further stretched by increased longevity: Now picture close to 1 billion of those brains over the age of 60 – and please remember that, less than 100 years ago, life expectancy was between 30 to 40 years. The rapidly evolving Knowledge Society is placing new and enormous demands on our “primitive” human brains. And the longer our lifespans, the more obvious the “cognitive gap”. Hence, from a health point of view, the growing 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 »

Welcome to the first edition of MetaCarnival: a Carnival of Carnivals (announced here), the new, monthly, and interdisciplinary gathering of blogs and blog carnivals.

Let's picture all participants in the shadow of an expansive sycamore tree, conducting a lively Q&A lunch discussion.

General Advice

Q: What would you recommend to live as long as possible, and as healthy as possible?
- Hourglass (biology of aging): Try Not To Stab Yourself Repeatedly. Or smoke. Or eat that much fast food...you get the idea.  "The vast majority of people are quite comfortable engaging in habits that cause great harm to the old person they will one day be, cutting off years or even decades of health."

Q: Can blogging help, too?
- I and the Bird (birds): Indeed. Just read about these life-changing moments in the Kenyan highlands, brought together spontaneously as a collaboration between researchers, conservationists, bloggers. And, yes, birds.

Sports (Well... Brain and Sports)

Q: Tell me something interesting about athletes and "The Zone".
- Encephalon (neuroscience and psychology): why don't we review this recent study on the Momentum Chain in Sports. You can conduct your own mini experiment while watching TV: watch the reactions of the players and the teams right after "precipitating events" to see if they actually lead to game-changing moments.

Medicine

Q: Should patients be patient?.
- SurgeXperiences (surgical experiences): Patience in indeed a virtue, especially Continue Reading »

If you are a blogger or read blogs often, you know that there are a good number of excellent blog carnivals focused on specific themes. If you are interested in medicine, you know what carnival to visit. Education, the same. Biology, neuroscience, nursing, birds, aging, philosophy...a variety of topics are very well covered in the blogosphere.

What you probably haven't come across is a high-quality "metacarnival" or "carnival of carnivals", where you can read the best blog posts ACROSS topics, subjects, disciplines.

This is why a few blog carnival "organizers" are launching next Monday a monthly rotating "MetaCarnival" to feature the most interesting posts from a variety of high-quality blog carnivals.

Participating blog carnivals so far, alphabetically: Continue Reading »

A couple of recent research findings are making the media rounds, bringing much needed attention to the high Alzheimer's rates among Latinos and to preventive approaches based on the Cognitive Reserve - such as, what jobs we choose:

More Alzheimer's risk for Hispanics, studies find (International Herald Tribune):

- Studies suggest that many Hispanics may have more risk factors for developing dementia than other groups, and a significant number appear to be getting Alzheimer's earlier. And surveys indicate that Latinos, less likely to see doctors because of financial and language barriers, more often mistake dementia symptoms for normal aging, delaying diagnosis.

- "This is the tip of the iceberg of a huge public health challenge," said Yanira Cruz, president of the National Hispanic Council on Aging. "We really need to Continue Reading »

"Choosing the right cognitive fitness product or program for senior living residents is harder than it sounds. But understanding residents' needs, identifying your objectives and considering the total cost of ownership will help set you on the right path."

Navigating the brain fitness landscape: do's and don'ts

Just saw a very interesting press release regarding computer-based neurocognitive assessments - a critical part of the brain fitness puzzle. How long will it take before consumers can have access to a reliable and credible annual "mental check-up"/ cognitive baseline?

HeadMinder Cognitive Stability Index: Computerized Neurocognitive ... (Press release)

- "The HeadMinder web-based Cognitive Stability Index (CSI) has proven more useful for blast-concussion detection than the ANAM computerized test battery the DoD currently employs. The CSI provides an immediate solution to clear the backlog of 400,000 IED-exposed service members in less than two years."

- "The CSI is a 30-minute, Internet-based, computerized test that provides automated, objective measures of attention, memory, response speed, and processing speed for initial evaluation of cognitive functioning. The CSI produces standardized reports that enable triage and decision-making appropriate to a user's qualifications - from medic to neuropsychologist to neurologist and other treatment team members."

We covered this emerging type of assessments in the article Computerized Cognitive Assessments: opportunities and concerns

- "In fact, one of the Continue Reading »

In yesterday's interview with Michael Posner, he says:

- "There is a growing number of studies that show the importance of interaction between our genes and each of our environments. Epigenetics is going to help us understand that question better, but let me share a very interesting piece of research from my lab where we found an unusual interaction between genetics and parenting."

- "Good parenting, as measured by different research-based scales, has been shown to build good effortful control which, as we saw earlier, is so important. Now, what we found is that some specific genes reduced, even eliminated, the influence of the quality of parenting. In other words, some children's development really depends on how their parents bring them up, whereas others do not - or do to a much smaller extent."

Now check out this fascinating article in the Economist:Domestication and intelligence in dogs and wolves | Not so dumb animals

- "Monique Udell of the University of Florida ... wondered whether learning rather than evolution explained his observations. Her team therefore worked with a mixture of pet dogs, dogs from animal shelters that had had minimal interaction with people, and wolves raised by humans."

- "As they report in Animal Behaviour, the wolves outperformed both shelter dogs and pets. Indeed, Continue Reading »

Michael I. Posner is a prominent scientist in the field of cognitive neuroscience. He is currently an emeritus professor of neuroscience at the University of Oregon (Department of Psychology, Institute of Cognitive and Decision Sciences). In August 2008, the International Union of Psychological Science made him the first recipient of the Dogan Prize "in recognition of a contribution that represents a major advance in psychology by a scholar or team of scholars of high international reputation."

Dr. Posner, many thanks for your time today. I really enjoyed the James Arthur Lecture monograph on Evolution and Development of Self-Regulation that you delivered last year. Could you provide a summary of the research you presented?

I would emphasize that we human beings can regulate our thoughts, emotions, and actions to a greater degree than other primates. For example, we can choose to pass up an immediate reward for a larger, delayed reward.

We can plan ahead, resist distractions, be goal-oriented. These human characteristics appear to depend upon what we often call "self-regulation." What is exciting these days is that progress in neuroimaging and in genetics make it possible to think about self-regulation in terms of specific brain-based networks.

Can you explain what self-regulation is?

All parents have seen this in their kids. Parents can see the remarkable transformation as their children develop the ability to regulate emotions and to persist with goals in the face of distractions. That ability is usually labeled ‘‘self-regulation.’’

The other main area of your research is attention. Can you explain the brain-basis for what we usually call "attention"?

I have been interested in how the attention system develops in infancy and early childhood.

One of our major findings, thanks to neuroimaging, is that there is not one single "attention", but three separate functions of attention with three separate underlying brain networks: alerting, orienting, and executive attention. Continue Reading »
