How Exer­cise Ben­e­fits the Brain (NewYork Times):

“To learn more about how exer­cise affects the brain, sci­en­tists in Ire­land recently asked a group of seden­tary male col­lege stu­dents to take part in a mem­ory test fol­lowed by stren­u­ous exercise.

First, the young men watched a rapid-fire lineup of pho­tos with the faces and names of strangers. After a break, they tried to recall the names they had just seen as the pho­tos again zipped across a com­puter screen. Read the rest of this entry »

(Editor’s note: Path­ways respon­si­ble for higher-order think­ing in the pre­frontal cor­tex (PFC), or exec­u­tive cen­ter of the brain, remain vul­ner­a­ble through­out life—during crit­i­cal early-life devel­op­men­tal win­dows, when the PFC fully matures in the early 20s, and finally from declines asso­ci­ated with old age. At all ages, phys­i­cal activ­ity and PFC-navigated social con­nec­tions are essen­tial com­po­nents to main­tain­ing brain health. The Expe­ri­ence Corps, a community-based social-engagement pro­gram, part­ners seniors with local schools to pro­mote purpose-driven involve­ment. Par­tic­i­pat­ing seniors have exhib­ited imme­di­ate short-term gains in brain regions vul­ner­a­ble to aging, such as the PFC, indi­cat­ing that peo­ple with the most to lose have the most to gain from envi­ron­men­tal enrichment.)

Over the last decade, sci­en­tists made two key dis­cov­er­ies that reframed our under­stand­ing of the adult brain’s poten­tial to ben­e­fit from life­long envi­ron­men­tal enrich­ment. First, they learned that the adult brain remains plas­tic; it can gen­er­ate new neu­rons in response to phys­i­cal activ­ity and new expe­ri­ences. Sec­ond, they con­firmed the impor­tance of social con­nect­ed­ness to late-life cog­ni­tive, psy­cho­log­i­cal, and phys­i­cal health. The inte­gra­tion of these find­ings with our under­stand­ing of indi­vid­u­als’ devel­op­men­tal needs through­out life under­scores the impor­tance of the “social brain.” The pre­frontal cor­tex (PFC) is par­tic­u­larly inte­gral to nav­i­gat­ing com­plex social behav­iors and hier­ar­chies over the life course.

Very inter­est­ing new data rein­forc­ing two main themes we have been ana­lyz­ing for a while:
1) We bet­ter start pay­ing seri­ous atten­tion (and R&D dol­lars) to lifestyle-based and non-invasive cog­ni­tive and emo­tional health inter­ven­tions, which are mostly ignored in favor of inva­sive, drug-based options
2) Inter­ven­tions will need to be per­son­al­ized. The study below ana­lyzes data at the coun­try level, but the same logic applies to the indi­vid­ual level

Although I no longer main­tain a clin­i­cal prac­tice, for years I worked with chil­dren with ADHD and their fam­i­lies. One thing I heard from many par­ents was that their child responded well to phys­i­cal exer­cise, that it helped their chil­dren burn off excess energy and main­tain a calmer and more focused state.

Indeed, evi­dence from sev­eral large-scale exper­i­men­tal stud­ies sug­gests that phys­i­cal activ­ity train­ing can have a pos­i­tive influ­ence on children’s cog­ni­tive func­tion­ing. Read the rest of this entry »

Research

Find­ings from NIH Expert Panel: The Amer­i­can Soci­ety on Aging asked Alvaro Fer­nan­dez to com­ment on the find­ings from a major cog­ni­tive health research review by the National Insti­tutes of Health. Lifestyle still mat­ters, and pro­tec­tive fac­tors against cog­ni­tive decline are led by cog­ni­tive train­ing, phys­i­cal activ­ity and cog­ni­tive engagement.

Sci­en­tific cri­tique of BBC brain train­ing exper­i­ment: Dr. Eliz­a­beth Zelin­ski shares her con­cerns about the April 2010 BBC study, which included sub­stan­tial and unex­plained dropout rates, and ques­tion­able out­come mea­sure­ment and interpretation.

The value of being bilin­gual and build­ing a Cog­ni­tive Reserve to pre­serve learn­ing and mem­ory even in the face of brain dam­age are explored in recent studies.

Teasers

Yahoo Opti­cal Illu­sions and teasers: Yahoo! has cre­ated an expanded sec­tion of illu­sions and teasers, and we were glad to con­tribute to it. Enjoy…and have a great summer!

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.

Sev­eral months ago we came across an excel­lent resource for cognitive/ brain fit­ness aimed at help­ing com­pa­nies offer qual­ity brain health infor­ma­tion to their employees.

While it is true that we often tend to believe all this “brain fit­ness” stuff is most rel­e­vant to our par­ents and/ or grand­par­ents, trust me, if you are read­ing this, you need it. Every­one with a brain can ben­e­fit from learn­ing about how his or her brain works and how to main­tain it with proper care.

And, from a company’s point of view, aren’t “tal­ent” and “human cap­i­tal” really all about brain fit­ness and cog­ni­tive performance?

The Con­fer­ence Board and the Dana Alliance for Brain Ini­tia­tives (descrip­tions below) pub­lished in 2008 a 44-page book­let to “teach sim­ple, prac­ti­cal strate­gies for incor­po­rat­ing brain-friendly prac­tices into day-to-day life”.  Your Brain at work: Mak­ing the sci­ence of cog­ni­tive fit­ness to work for you is the first of three planned book­lets on cog­ni­tive fitness.

The Con­fer­ence Board and the Dana Alliance have allowed Sharp­Brains to share the fol­low­ing Action Plan with our read­ers, straight from Your Brain at work brochure. At the bot­tom of this post we also share instruc­tions on how indi­vid­u­als and com­pa­nies can get their own copies of this excel­lent brochure. Read the rest of this entry »

Try eat­ing food with one chop stick.

It is pos­si­ble, for cer­tain types of food. But prob­a­bly not the best approach.

Let’s now talk brain health.

Dr. Larry McCleary is a for­mer act­ing Chief of Pedi­atric Neu­ro­surgery at Den­ver Children’s Hos­pi­tal, and author of the The Brain Trust Pro­gram (Perigee Trade, 2007). He agreed to help us answer an impor­tant, yet often neglected, ques­tion: Given That We Are Our Brains, How do We Nour­ish Them?

Alvaro: Dr. McCleary, Why did a for­mer neu­ro­sur­geon such as your­self develop an inter­est in brain health pub­lic education?

Dr. McCleary: For two rea­sons … I am a Boomer and am try­ing to max­i­mize my own brain health. Also, there is much excit­ing research doc­u­ment­ing how we can be proac­tive in this regard. This infor­ma­tion needs to be dis­sem­i­nated and I would like to help in this process.

And what is the sin­gle most impor­tant brain-related idea or con­cept that you would like every per­son in the planet to fully understand?

The most impor­tant take home mes­sage about brain health is that we now know that no mat­ter what your brain sta­tus or age, there is much you can do to sig­nif­i­cantly improve brain func­tion and slow brain aging. Based on emerg­ing infor­ma­tion, what is espe­cially nice is the fact that unlike many things in life our brain health is largely under own control.

What are the most impor­tant ele­ments to nour­ish our brains as we age?

I approach this ques­tion much like an ath­lete pre­pares for com­pe­ti­tion. They uti­lize a holis­tic approach. Read the rest of this entry »
