Brain Fitness in the News

Brain Fitness @ PBS: PBS featured a fantastic special program on neuroplasticity and brain fitness during the month of December. Before you ask: as of today, the DVD of the program is still not available in PBS online shop. We expect to see it there in 2-3 weeks. We will keep you informed.

The Huffington Post started featuring a column written by me: you may enjoy taking a look at Alvaro Fernandez – Living on The Huffington Post.

Jogging our Brains for Brain Vitality, Healthy Aging-and Intelligence!: a roundup of several great recent articles on memory, aging, IQ and cognitive abilities such as self-control.

Health & Wellness

Brain Training: No Magic Bullet, Yet Useful Tool. Interview with Elizabeth Zelinski: Dr. Zelinski, leading researcher of the IMPACT study, shares fascinating insights. For example: “…cognitive enhancement requires the engagement in a variety of activities, those activities must be novel, adaptive and challenging-which is why computer-based programs can be helpful. But even at a more basic level, what matters is being engaged with life, continually exposed to stimulating activities, always trying to get out of our comfort zones, doing our best at whatever we are doing. A major typical misconception is that there is only one general intelligence to care about. In reality, we have many different cognitive abilities, such as attention, memory, language, reasoning, and more, so it makes sense to have different programs designed to train and improve each of them.”

How to Evaluate and Choose a Brain Fitness Program: To help you navigate the growing number of computer-based programs and games, we published this 10-Question Checklist, based on dozens of interviews with scientists, experts and consumers.

Travel and Engagement as Good Brain Exercise: As we’ve seen, novelty, variety and challenge are the key guidelines for “brain exercise” that help build new neural connections, force one to be mindful and pay attention, improve abilities such as pattern-recognition, and generally contribute to lifelong brain health. In this post we feature the brain building / mind expanding experience of a SharpBrains friend working in Namibia.

Alzheimer’s Prevention and Diagnostic Tests: analysis of several recent articles on emerging research behind Alzheimer’s diagnostic and prevention.

Corporate Wellness and Training

Cognitive Reserve and Intellectually Demanding Jobs: a recent study shows how “Intellectually demanding work was associated with greater benefit to cognitive performance in later life independent of related factors like education and intelligence.”

Cognitive Health and Baby Boomers- 6 Points to Keep in Mind: based upon an excellent McKinsey report titled Serving Aging Baby Boomers, we discuss a variety a news articles, including interesting numbers, some bad news, and some good news.

Lifelong Learning Is Changing My Brain: Andreas, the neuroscience PhD student who spent last summer working with SharpBrains, writes some reflections on his experience and on how scientists and business professionals can learn from each other.

Over the last months, thanks to the traffic growth of SharpBrains.com (over 100,000 unique visitors per month these days, THANK YOU for visiting today and please come back!), a number of proactive book agents, publishers and authors have contacted us to inform us of their latest brain-related books. We have taken a look at many books, wrote reviews of The Dana Guide to Brain Health book review and Best of the Brain from Scientific American, and interviewed scientists such as Judith Beck, Robert Emmons and James Zull.

Now we are launching a new Author Speaks Series to provide a platform for leading scientists and experts writing high-quality brain-related books to reach a wide audience. We are honored to start the series with an article by Larry McCleary, M.D, former acting Chief of Pediatric Neurosurgery at Denver Children’s Hospital, and author of The Brain Trust Program: A Scientifically Based Three-Part Plan to Improve Memory, Elevate Mood, Enhance Attention, Alleviate Migraine and Menopausal Symptoms, and Boost Mental Energy (Perigee Trade, 2007).

Without further ado, let’s enjoy Dr. McCleary’s article:

Brain Evolution and Why it is Meaningful Today to Improve Our Brain Health

You may feel overwhelmed by the stream of seemingly contradictory suggestions regarding the best way to maintain mental clarity as you age. Based on an analysis of seminal factors in the development of modern brain anatomy, I believe it is possible to make some very compelling recommendations for growing big brains, enhancing their function, and making them resistant to the aging process. These may be loosely categorized as factors pertaining to the mental or physical attributes of the brain. Although they are not truly independent entities, such a conceptualization provides a basis for the generation of brain healthy prescriptions. Diet, physical exercise, and stress reduction enhance neuronal resilience. Sleep and mental stimulation are vital for cognitive ability, learning, and memory.

Diet: Follow a modern shore-based/marine diet including seafood in its most general sense, non-starchy vegetables of all colors, berries, and eggs. Other sources of lean protein containing long-chain omega 3 fatty acids such as free range beef, chicken, bison, or elk are nutritious alternatives.

Physical exercise (Think ‘fight or flight’ activity.): Include all types. Aerobic activities such as swimming, bicycling, walking, or hiking for promotion of vascular health and weight control; resistance training for promotion of neurotrophic factors, naturally occurring compounds that make brain cells more resistant to aging, such as IGF-1 (Insulin-like growth factor-1) and BDNF (Brain-derived neurotrophic factor); and balance, coordination, and agility training such as ping-pong, balance beam, trampoline, and jumping rope to enhance cognitive speed and motor skills.

Stress Control: From an evolutionary perspective, stressors (such as meeting a cave bear) and intense physical activity (running or fighting) were brief in duration and usually occurred together. Modern stressors (psychological or emotional stress) tend to be unremitting and are generally uncoupled from the physical (fight or flight) component, meaning stress develops without any associated physical activity. Such intense physical pursuits are now called exercise. Not surprisingly, exercise is a perfect physiologic antidote for stress due to its beneficial impact on cortisol (the ‘stress’ hormone) and blood pressure and should be incorporated into any program of stress reduction.

Adequate sleep: The body needs rest, but the brain requires sleep. Acute or chronic sleep deprivation causes devastating short and long-term consequences to brain anatomy (synaptic loss) and function (memory and learning difficulties). Off-line information processing and memory consolidation are additional sleep-related benefits.

Mental stimulation: Brain-training, a cognitively challenging lifestyle, novelty, and socialization are vital for the promotion of neuronal plasticity and neurogenesis (the formation of new nerve cells and neuronal connections), the enhancement of specific brain functions such as memory, and the development of cognitive reserve –additional mental processing potential that may be brought online when needed.

The combination of these recommendations, each of which was instrumental in the transformation from primitive to modern nervous systems, provides a template for the most logical approach for enhancing mental function and resisting neurodegeneration as we travel through life.

The Evolutionary Rationale

The human brain clearly has the genetic potential for dramatic expansion. This was illustrated about Read the rest of this entry »

It’s clear that our society has changed faster than our genes. Instead of being faced with physical, immediately life-threatening crises that demand instant action, these days we deal with events and illnesses that gnaw away at us slowly without any stress release.

Dr. Robert Sapolsky, in an interview about his book Why Zebras Don’t Get Ulcers, points out that humans uniquely “can get stressed simply with thought, turning on the same stress response as does the zebra.” But, the zebra releases the stress hormones through life-preserving action, while we usually just keep muddling along, getting more anxious by the moment.

Prolonged exposure to the adrenal steroid hormones, like cortisol, released during stress can damage the brain and block the formation of new neurons in the hippocampus, which is the key player in encoding new memories in your brain. Recent studies have shown these neurons can be regenerated with learning and environmental stimulation, but while short-term stress may improve attention and memory, chronic stress leads indirectly to cell death and hampers our ability to make changes and be creative enough to even think of possible changes to reduce the stress.

What are the best defenses against chronic stress?

1. Exercise strengthens the body and can reduce the experience of stress, depression, and anxiety. Exercise promotes arousal and relaxation and improves quality of sleep.

2. Relaxation through meditation, biofeedback, yoga, or other techniques to lower blood pressure, slow respiration, slow metabolism, and release muscle tension.

3. Empowerment because attitudes of personal confidence and control of your environment, even if illusory, resolve the stress response.

4. Social network of friends, family, and even pets help foster trust, support, and relaxation.

So hey, go ahead, call your mom. It may save your life!
