We offered some Brain Fitness Predictions in our Market Report , including…

“7. Doctors and pharmacists will help patients navigate through the overwhelming range of available products and interpret the results of cognitive assessments. This will require significant professional development efforts, given that most doctors today were trained under a very different understanding of the brain than the one we have today.”

The American Medical News, a weekly newspaper for physicians published by the American Medical Association, just published an excellent article along those lines:

Steps to a nimble mind: Physical and mental exercise help keep the brain fit
– Neuroscience is uncovering techniques to prevent cognitive decline.

A few quotes:

- It’s an example that highlights a wave of new thinking about the importance of brain fitness.

- Until recently, conventional wisdom held that our brains were intractable, hard-wired computers. What we were born with was all we got. Age wore down memory and the ability to understand, and few interventions could reverse this process. But increasingly, evidence suggests that physical and mental exercise can alter specific brain regions, making radical improvements in cognitive function.

- With nearly 72 million Americans turning 65 over the next two decades, physicians need the tools to handle growing patient concerns about how to best maintain brain health. Armed with this new brand of science, frontline physicians will be better equipped to address the needs of aging baby boomers, already in the throes of the brain fitness revolution.

- “Encourage them to exercise the brain in novel and complex ways,” he says.

One of the physicians quoted in the article is Gary J. Kennedy, MD, Director of the Division of Geriatric Psychiatry at Montefiore Medical Center in NYC and a professor in the Dept. of Psychiatry and Behavioral Sciences at Albert Einstein College of Medicine.

To put the AMA article in better perspective for SharpBrains readers, we asked Dr. Kennedy a few follow-up questions. Below you have his questions.

As the Brain Fitness industry continues to gain momentum, and people explore all the incredible brain-training tools being developed, we hope that enthusiasts don’t take their eye off the importance of the physical health of the brain and all the systems it communicates with. The brain is unique in that it houses our cognitive and emotional capacities in the form of the mind. It is a ‘cognitive’ organ that hungers for stimulation from new experiences and challenges. Many brain fitness programs strive to satisfy this need. Yet the brain is also a physical organ that plays by many of the same rules as the heart, lungs, liver and kidneys. To stay healthy and perform optimally it requires quality nutrition, physical activity and optimal sleep. The brain, especially, relies on a healthy vascular system to efficiently deliver oxygen and key nutrients and remove waste. In fact, the brain uses approximately 20% of the oxygen we breathe to satisfy its high-energy demands. Given that the brain only weighs about 2% of the body, we can consider it an energy hog and we must cater to its needs very carefully.

Nutrients play key roles in brain function. Several have shown efficacy in clinical trials treating cases of mood disorders, cognitive decline and of course benefiting the physical health of the brain. Nutrients are both the raw materials employed in creating new neural connections and Read the rest of this entry »

In other words, may some foods be specifically good for brain function?

For a great in-depth review of the effects of food on the brain you can check out Fernando Gomez-Pinilla’s recent article in Nature Reviews Neuroscience (reference below). Here is an overview of the state off the research.

Several components of diet seem to have a positive effect on brain function.

Omega-3 fatty acids

These acids are normal constituents of cell membranes and are essential for normal brain function. Omega-3 fatty acids can be found in fish (salmon), kiwi, and walnuts. Docosahexaenoic acid, or DHA, is the most abundant omega-3 fatty acid in cell membranes in the brain. The human body produces DHA but not enough. So we are dependent on the DHA that we get from what we eat.

A randomized double-blind controlled trial (which means seriously conducted scientific study) is currently looking at the effect of taking omega-3 fatty acids on children’s performance at school in England. Preliminary results (Portwood, 2006) suggest that Read the rest of this entry »
