We define Brain Fit­ness as hav­ing the brain-based cog­ni­tive, emo­tional and self-regulation capac­i­ties required to suc­ceed in one’s envi­ron­ment. Not every­one is exposed to the same men­tal demands nor do we all have the same start­ing points. This means we need to stop look­ing for ‘magic pills’ and invest more resources in devel­op­ing toolk­its and infra­struc­ture sim­i­lar to what the phys­i­cal fit­ness indus­try has done over the last 30–40 years.

The fol­low­ing ques­tion guides much of our work at Sharp­Brains: “What tools pro­vide the right kind of expe­ri­ence to refine our brains from a struc­tural and func­tional point of view to har­ness neu­ro­plas­tic­ity into real-world ben­e­fits?” We try to pro­vide good infor­ma­tion and answers by con­stantly mon­i­tor­ing and ana­lyz­ing the state of sci­ence and the marketplace—and by shar­ing these analy­ses via appro­pri­ate plat­forms with orga­ni­za­tions and indi­vid­u­als. Sharp­Brains doesn’t sell, develop or endorse prod­ucts in order to avoid con­flicts of interest.

The main con­text for brain fit­ness is this: Read the rest of this entry »

In light of the cur­rent BBC-led con­tro­versy on whether “brain train­ing” works, we believe it is crit­i­cal to spend some time dis­cussing the basics of brain func­tion­ing and brain-healthy lifestyles, what “brain train­ing” is and isn’t (to be accu­rate, the BBC didn’t test Brain Train­ing as a cat­e­gory, only the new games that their researchers chose to build from scratch and des­ig­nate as “brain train­ing” ignor­ing pre­vi­ous research), what method­olo­gies for brain train­ing are in fact backed up by sci­ence (med­i­ta­tion, cog­ni­tive ther­apy, biofeed­back, com­put­er­ized cog­ni­tive train­ing) as valu­able for a vari­ety of pop­u­la­tions and goals, and how con­sumers and pro­fes­sion­als can learn to nav­i­gate the grow­ing array of claims. Sharp­Brains wants to con­tribute to a healthy con­ver­sa­tion by shar­ing online a new online resource based on the con­tent from the book The Sharp­Brains Guide to Brain Fit­ness (May 2009, $19.95), by Alvaro Fer­nan­dez and Dr. Elkhonon Goldberg.

The new resource is avail­able via the Nav­i­ga­tion Bar as “HOW-TO GUIDE: all about brain fit­ness”, and below are its main sec­tions. You can engage in the con­ver­sa­tion in this blog, via Face­book, Twit­ter, and LinkedIn. Enjoy!

	Debunk­ing 10 Brain Myths You are a life­long learner. You may also be a care­giver, or a pro­fes­sional in fields such as health­care, edu­ca­tion, or psy­chol­ogy. The goal of this resource is to help you make informed deci­sions about brain health and cog­ni­tive fit­ness, based on lat­est sci­en­tific find­ings. First of all, let’s debunk some com­mon myths. Keep read­ing.
	1. Brain Fit­ness Fundamentals In order to make informed deci­sions about brain health and brain train­ing, you need to first under­stand the under­ly­ing orga­ni­za­tion of the human brain and how it evolves across our lifes­pan. For exam­ple, the brain is com­posed of a num­ber of spe­cial­ized regions serv­ing dis­tinct func­tions, our life and pro­duc­tiv­ity depend on a vari­ety of brain func­tions, not just one, and there is noth­ing inher­ently fixed in the tra­jec­tory of how brain func­tions evolve as we age. Keep read­ing.
	2. The 4 Pil­lars of Brain Maintenance Thanks to life­long neu­ro­plas­tic­ity and neu­ro­ge­n­e­sis, our lifestyles and actions play a mean­ing­ful role in how our brains phys­i­cally change. Now, there is no “gen­eral solu­tion” or “magic pill” for brain main­te­nance. A multi-pronged approach cen­tered on nutri­tion, stress man­age­ment, and both phys­i­cal and men­tal exer­cise is rec­om­mended for bet­ter brain health. Keep read­ing.
	3. Brain Train­ing vs. Men­tal Activity In this sec­tion we focus on men­tal exer­cise – which we will call brain train­ing, to dis­tin­guish it from men­tal activ­ity in gen­eral. Brain train­ing goes beyond men­tal activ­ity. It is the struc­tured use of cog­ni­tive exer­cises or tech­niques aimed at improv­ing spe­cific brain func­tions, and can be deliv­ered in a num­ber of ways: med­i­ta­tion, cog­ni­tive ther­apy, cog­ni­tive train­ing, biofeed­back. Keep read­ing.
	4. Mak­ing Informed Brain Train­ing Decisions The state of the research does not allow for strong “pre­scrip­tions” of spe­cific prod­ucts: we want to offer you the best infor­ma­tion avail­able today so that you can make bet­ter informed deci­sions. Dif­fer­ent peo­ple face dif­fer­ent cog­ni­tive demands, and have dif­fer­ent start­ing points, so there is no gen­eral solu­tion for every­one and every­thing. As in phys­i­cal fit­ness, informed con­sumers and pro­fes­sion­als must ask them­selves a num­ber of ques­tions. Keep read­ing.
	5. Brain Fit­ness through the Lifespan The same way there are many rea­sons to exer­cise our bod­ies (run in a marathon, stay in shape, lose weight, become an Olympian, have strong abdom­i­nal mus­cles, etc.), there are many rea­sons to exer­cise our brains. In this chap­ter, we review a few cur­rent and future appli­ca­tions of brain train­ing through the lifes­pan, includ­ing edu­ca­tion, cor­po­rate well­ness, retire­ment com­mu­ni­ties, clin­i­cal con­di­tions, and more. Keep read­ing.
	6. Ready for the Future? In this sec­tion our aim is to describe the trends we think are impor­tant in order to help you be ready for the future. Informed and proac­tive adults will look for solu­tions to inte­grate brain fit­ness to their every­day activ­i­ties. Pro­fes­sion­als will iden­tify oppor­tu­ni­ties to offer new ser­vices and pro­grams. We hope this chap­ter will give you ideas as to how to intro­duce brain fit­ness in your per­sonal life and/or your work­place. Keep read­ing.
	7. Open­ing the Debate Our ulti­mate goal is to stim­u­late dis­cus­sion. In this final sec­tion we want to pro­vide you, proud brain own­ers and ambas­sadors of brain fit­ness, with addi­tional food for though. Pro­cess­ing new infor­ma­tion is a stim­u­lat­ing intel­lec­tual exer­cise, and dis­cussing insights and open ques­tions with a group of peo­ple can be equally if not more stim­u­lat­ing. Keep read­ing.

Tur­bocharg­ing the Brain–Pills to Make You Smarter?

“Will a pill at break­fast improve con­cen­tra­tion and memory—and will it do so with­out long-term detri­ment to your health?”

Their answer, in short: not really, not any­time soon.

I couldn’t agree more. Let’s pay real atten­tion to non-invasive options to aug­ment cog­ni­tion, from exer­cise to cog­ni­tive train­ing and meditation.

For more con­text, you may enjoy my recent arti­cle Prepar­ing Soci­ety for the Cog­ni­tive Age, pub­lished in Fron­tiers in Neuroscience.

The July/ August 2009 issue of The Jour­nal on Active Aging includes my arti­cle Why We Need to Retool “Use It Or Lose It“

An excerpt:

“By now you have prob­a­bly heard about brain plas­tic­ity, the life­long capac­ity of the brain to change and rewire itself in response to the stim­u­la­tion of learn­ing and expe­ri­ence. The lat­est sci­en­tific research shows that spe­cific lifestyles and actions can improve the health and level of func­tion­ing of our brains, no mat­ter our age.

Of par­tic­u­lar impor­tance to main­tain­ing cog­ni­tive func­tion­ing through life are the hip­pocam­pus (deep inside the brain, part of what is called the lim­bic sys­tem), which plays a role in learn­ing and mem­ory; and the frontal lobes (behind your fore­head), which are key to main­tain­ing decision-making and auton­omy. Is there a way to phys­i­cally pro­tect these parts of the aging brain? Yes. But the right answer is far from “do one more cross­word puz­zle” or “do more X” (what­ever X is). The key is to add sig­nif­i­cantly dif­fer­ent activ­i­ties to ensure a flow of nov­elty, vari­ety and chal­lenge, com­bin­ing phys­i­cal and men­tal exer­cise while not ignor­ing fac­tors such as stress man­age­ment and bal­anced nutrition.

We need, in other words, to retool our under­stand­ing and prac­tice of “Use it or lose it.” We must focus on the impor­tance of get­ting out of our phys­i­cal and men­tal rou­tines and activ­i­ties to get the ben­e­fits of real exercise—physical and mental.”

Learn­ing & the Brain is a con­fer­ence that gets marked on my cal­en­dar annu­ally because I always return home hav­ing either been exposed to new infor­ma­tion, or with a new per­spec­tive on an old topic. Last month’s con­fer­ence in Cam­bridge, MA, themed Using Emo­tions Research to Enhance Learn­ing & Achieve­ment, was no excep­tion. As with pre­vi­ous con­fer­ences, in addi­tion to the many keynote ses­sions, I focused on the adult learn­ing strand, since so much of my time is spent pro­vid­ing pro­fes­sional devel­op­ment for, and col­lab­o­rat­ing with adults. Here are five con­fer­ence cues as they relate to education.

1. CHALLENGE YOURSELF WITH NEW LEARNING

Aaron Nel­son stated that our mem­ory starts to decline between ages twenty-five and thirty, or to phrase it a bit more pos­i­tively, Sam Wang says our mem­ory peaks around age thirty. On the other end of the age spec­trum, accord­ing to Ken Kosik, there is unequiv­o­cal evi­dence that edu­ca­tion pro­tects against Alzheimer’s. Both Nel­son and Kosik men­tioned the the­ory of cog­ni­tive reserve, which trans­lates roughly to the more we learn, the more con­nec­tions we cre­ate, and there­fore the greater the neu­ronal buffer we have to draw upon as we age.

Elkhonon Gold­berg, at last April’s con­fer­ence, stated that “as one ages, the domain of the novel shrinks, and the domain of what is known grows”. He cau­tioned the audi­ence to beware of being on men­tal autopi­lot. Thus, the goal is not to sim­ply get bet­ter at doing more of the same. The type of learn­ing that makes a dif­fer­ence con­sists specif­i­cally of new, novel chal­lenges. The result of such engage­ment is that Read the rest of this entry »

“If Dr. Rob can inter­view Santa, why can’t I inter­view a select group of health & med­ical blog­gers? They will have some good ideas to share”.

So did President-elect Obama came to real­ize a few days ago. After his peo­ple kindly con­tacted our peo­ple, we felt com­pelled to grant him open access to our col­lec­tive wis­dom. With­out fur­ther ado, below you have Grand Rounds 5:12 — a Q&A ses­sion led by the incom­ing Pres­i­dent on how to reform (for the bet­ter, we hope) healthcare.

On Health Insurance

Q:  How does the blo­gos­phere per­ceive the prob­lem of hav­ing a sig­nif­i­cant group of peo­ple uninsured?

Health Insur­ance Col­orado: a grow­ing eco­nomic bur­den, which may lead to emer­gency rooms turn­ing peo­ple away if they are unable to pro­vide proof of health insurance.

Dr Rich: well, a recent arti­cle in the Jour­nal of the Amer­i­can Med­ical Asso­ci­a­tion showed how over­crowd­ing in Amer­i­can emer­gency rooms is NOT due to the unin­sured. Rather, it is due to insured Amer­i­cans who can­not get in to see their pri­mary care physi­cians. We may need improved care both for the insured and unin­sured groups.

Insure­Blog: I’d sec­ond that. Lack of health insur­ance is a major prob­lem but is it really our Biggest Problem?

It’s All about Attitude

Q: You may have heard my cam­paign mantra, “Yes We Can”. Can I count on your support?

ButY­ouDont­Look­Sick: Yes. If Leslie Hunt can talk so openly about her chronic ill­ness (Lupus) yet ful­fill her Amer­i­can Idol dreams, we can ful­fill our dreams too.

Notes of an Anes­the­sioboist: you are talk­ing to the group of pro­fes­sion­als will­ing to self-experiment with our own body for the ben­e­fit of sci­ence and our patients.

Med­views: My wife, son, and I signed up to work as med­ical vol­un­teers for your upcom­ing inauguration.

Emergi­Blog: I am on board too. But, please, remem­ber that car­ing is the essence of nurs­ing. And that is why my patients will always be my patients and never my  clients.

Neu­roan­thro­pol­ogy: Mr. President-elect, it seems to me that, despite all our good inten­tions, bal­anc­ing the bud­get and mul­ti­ple com­pet­ing pri­or­i­ties will be a chal­lenge. May I sug­gest you start prac­tic­ing some capoeira for equi­lib­rium training?

Shrink Rap: Happy to help. Now, we will need to pro­tect some time for qual­ity sleep time.

Train­ing

Q: I am encour­aged by your words. How can my team and I bet­ter sup­port you in your daily activities?

Aequa­nim­i­tas: we need more role mod­els for us to “learn to think, observe, and com­pare” and that the patient is our “first, last, and only teacher”.

Mud­phud­der: Couldn’t agree more. We need Read the rest of this entry »
