Old brains, better brains?

I haven’t read this book yet, but I plan to. Even the book review for it reposted below is fascinating. Older brains are better brains? Keeping with the theme of reality contradicting stereotypes about age also see this earlier post:

Hope I die before I get old

The Mature Mind
The Positive Power of the Aging Brain

by Gene D. Cohen
Basic Books, 2005
Review by David M. Wolf, M.A. on Feb 20th 2007
Volume: 11, Number: 8

In this readable, concise report of his own and relevant research into the aging brain, Dr. Cohen delivers a real basis for hope. We’re not just getting older; we’re getting better. Maybe. And here’s the point: we can mature and get better if we do the right things and participate in the right things. This book fully describes what activities, changes, or interventions are useful and beneficial. Cohen uses scientific studies and case examples to make the facts plain. Everyone over forty should read this book, because its findings will directly influence career moves and lifestyle choices.

Cognition, creativity, intelligence, and, especially, memory (or its impairment) are of vital concern to most people as they age. The Mature Mind inquires into the brain’s changes as we age and relates these to how the human mind manages in the face of the brain’s changes. Our job as educated people is to learn what is happening and make the adjustments and commitments that lead toward a vigorous maturity.

The brain, Cohen reports, is not just losing neurons and getting old; the brain is also developing, growing new neural networks and cells, and becoming more balanced between its two hemispheres. The worst “rubbish” from the past, according to Cohen, is in the false phrase, “You can’t teach an old dog new tricks.” The essence of successful maturity is to continue learning, growing, challenging the brain and the whole human being as it ages. Doing this with wisdom, creativity, social support and attention to everyone’s need for a sense of control and mastery is the right approach to successful aging.

Cohen’s axiom for what drives and sustains us throughout life he names “Inner Push.” As he uses this insight, it appears synonymous with the philosopher Spinoza’s idea of the “fiery Conatus”, and also, quite like Henri Bergson’s more poetic idea of the elan vital. Inner Push is there while we breathe, and it’s up to us to shape its energies.

We do this in the second half of life according to Four Phases, says Cohen: Midlife Reevaluation (ages 40-65), Liberation phase (50s through 70s), Summing Up (late 60s through 70s-80s), and Encore phase, until the end of life. The Mature Mind is largely a characterization and description of these phases, plus some helpful essays on creativity in old age and lists of resources. Cohen also spends some ink debunking “midlife crisis”, which he says is a myth.

The “power” and “potential” of older minds is rooted in a human brain that not only ages, but also, develops over time. We may individually be surprised by age, but the biological brain is not: the program includes adaptive responses in which the brain can adjust and rewire itself. This physiological change can be far greater than people ordinarily suppose if the aging adult remains active mentally, accepts challenges individually and socially, and gets some regular exercise.

In other words, the hopeful result depends in large part on how much the brain is stimulated with learning and activity of the kind that promotes vitality. Depend on TV, let your friends die off, become isolated and alone, retire, become or remain inactive physically: these are the old habits that lead to degeneration and death. However, exercise, social engagement, creative (even artistic) expression, phased retirement or part-time work, volunteering, learning new things over which one develops a feeling of growing mastery–these kinds of changes lead to surprisingly vital older people who live better and longer than their unlucky peers.

Cohen has some startling findings in his data that supports his views. One in particular is that aging brains contain expansive bundles of neurons not available to the young, bundles that reflect a lifetime of experience. At the same time these brain assets become more balanced between both hemispheres, doing with the whole brain what the young cannot yet do or can do only with Left or Right hemispheres singly.

Older people have a “developmental intelligence” which better balances physical and emotional maturity. Development is wrongly seen as just for kids. The maturing brain is more capable of what Cohen calls “relativistic thinking” (not black and white), “dualistic thinking” (resolving opposites), and “systematic thinking” (big picture). These capabilities give the mature mind truly “advanced” status. It can take a lifetime to develop the basis for these advances, and they have enormous individual and social implications.

So, this book is more than a useful guide to saving one’s own aging brain. It is also a review laying a basis for social, even political changes, reflecting the untapped potential of our aging American population.

Finally, the FDA questions animal testing


“The promising diabetes drug Galvus recently got turned back by the U.S. Food and Drug Administration.

About 5,500 patients had taken the medicine in clinical trials at that point, but the problem apparently wasn’t with them. The agency was worried because some monkeys who were given high doses of Galvus developed skin lesions. Humans who took normal amounts of the drug for as long as two years didn’t get the sores, but the FDA refused to approve the drug until it saw more testing in people who might be at higher risk.

The decision spotlighted an important unresolved scientific question: What do the results of animal studies really tell us about humans? That question still puzzles researchers even though guinea pigs, lab rats and their brethren have long been part of experiments.

WOK carefully

There is good news and bad news from the Center For Science In The Public Interest..

The good news is that Chinese restaurant food has not gotten any worse for our health or our weight.

The CSPI was careful to be serious about labeling this as a good thing, because other types of restaurant foods have gotten worse in the years since they last made a restaurant food survey.

The bad news is that Chinese restaurant food still sucks.

Even vegetable dishes – without rice – can have more than 1/2 a days calories and an entire days allowance for sodium. Sodium has been linked to osteoporosis and shorter life spans.

I have read all sorts of scientists, doctors, trainers and health advocates tell people to only eat half of what they are served when they go out to eat. Many recommend asking the server to doggie bag your extra half of a serving before bringing it out to the table.

The status of this advice seems to me to be moving from obscure diet tip to well known, well accepted health rule of thumb.

I’m not sure if even eating at vegan restaurants is beyond the realm of this advice. The bulk of the calories in Chinese restaurant food comes from oil. A sandwich at the falafel shop can be just as deep fried as General Tso’s tofu or the eggplant dish at your favorite vegan place.

Anyway, here is the article. It is worth reading in addition to watching the video.
