Here you have the September edition of our monthly newsletter covering cognitive health and brain fitness topics. Please remember that you can subscribe to receive this Newsletter by email, using the box at the top of this page.

In the current edition of The Journal on Active Aging, I discuss why we need to Retool “Use it or lose it”, and why routine, doing things inside our comfort zones, is the most common enemy of the novelty, variety and challenge our brains need. You can read the full article for free Here.

Brain Reserve

Given the growing media coverage mentioning the terms Cognitive Reserve and Brain Reserve, you may be asking yourself, “What exactly is my Cognitive (or Brain) Reserve?”

The cognitive reserve hypothesis, tested in multiple studies, states that individuals with more cognitive reserve can experience more Alzheimer’s disease pathology in the brain (more plaques and tangles) without developing Alzheimer’s disease symptoms.

How does that work? Scientists are not sure but two possibilities are considered.
1. One is that more cognitive reserve means more brain reserve, that is more neurons and connections (synapses) between neurons. Individuals with more synapses would then have more synapses to lose before the critical threshold for Alzheimer’s Disease is reached.
2. Another possibility is that more cognitive reserve means more compensatory processes. The brain of individuals with more cognitive reserve would use more alternative networks to compensate for the damages caused by the pathology in previously used networks.

In a newly published study, Roe and colleagues from Washington University in St. Louis, used the number of years of education as a measure of cognitive reserve. Why years of education? Because previous studies have shown that people who have more education also exhibit a greater resistance to Alzheimer’s symptoms, even while pathological changes are occurring in the brain (see Bennett el al., 2003 or Roe, Xiong, et al., 2008).

Roe and her colleagues studied 198 individuals whose mean age was 67. Out of these 198 individuals, 161 were nondemented and 37 were diagnosed with Alzheimer’s Disease.

All the participants in the study took a Read the rest of this entry »

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 Read the rest of this entry »

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 Read the rest of this entry »

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. Read the rest of this entry »

Welcome to the third edition of Hourglass, the monthly virtual gathering of bloggers to discuss the Biology of Aging.

For today’s edition, let’s imagine all participants sitting around a table leading a lively Questions & Answers session, discussing as a group, listening, talking. (And, well, aging.)

Q: What is aging?
Ms. Wikipedia: “Ageing or aging (American English) is the accumulation of changes in an organism or object over time. Ageing in humans refers to a multidimensional process of physical, psychological, and social change. Some dimensions of ageing grow and expand over time, while others decline. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand.”

Aging may not be the sexiest  of words in our vocabulary. Unless, of course (as I heard somewhere recently but can’t properly credit), you consider the most common alternative.

Q: If the objective of anti-aging research is to extend lifespan, isn’t there a risk that we may neglect quality of life. After all, would people really like to spend more years afflicted by the diseases and the decline that often come with age?
Ed (dragged to the discussion by Chris and Alvaro): I have relatively good news to share. A recent  University of Southern Denmark found that the proportion of elderly Danes who manage to remain independent holds steady at Read the rest of this entry »

We had a very fun session titled Teaching Brain Fitness in Your Community at an American Society on Aging (ASA) conference for health professionals a couple of weeks ago. Full house, with over 60 attendants and very good participation, showing great interest in the topic. I can’t wait to see the evaluations.

These are some of the resources I promised as a follow-up, which can be useful to everyone interested in our field:
