Here you have the Octo­ber edi­tion of our monthly newslet­ter cov­er­ing cog­ni­tive health and brain fit­ness topics.

We recently run an online sur­vey among sub­scribers of our monthly eNewslet­ter, and over 500 peo­ple said we have helped them make bet­ter per­sonal or pro­fes­sional deci­sions on how to main­tain and improve brain fit­ness. Respon­dents also had many good ques­tions to ask, so I have selected 15 com­mon ones, paraphrased/ syn­the­sized them below, and answered them by link­ing to our most rel­e­vant posts and resources. I hope you enjoy the FAQ session.

Q: I teach a brain fit­ness class at my library/ senior center/ school, using much of your info. Can you share some of your pre­sen­ta­tions?
A: Yes, we have just decided to share, using a Cre­ative Com­mons Attri­bu­tion No Deriv­a­tives License, the full pre­sen­ta­tion of my recent book talk at New York Pub­lic Library (opens video in YouTube). As long as you give credit to Sharp­Brains and don’t mod­ify it, you are free to use the pre­sen­ta­tion you can view and down­load HERE.

Q: What exactly does neu­ro­plas­tic­ity mean, and why is it so impor­tant for edu­ca­tion and health?
A: Start by read­ing how learn­ing changes your brain.

Q. Is this only rel­e­vant for older adults? Can I also apply it in the work­place (I am 47)
A. I strongly sus­pect you do have a human brain, so you may ben­e­fit from these Ten Habits of Highly Effec­tive Brains. Fur­ther, HR depart­ments would do well to start pay­ing more atten­tion to Cog­ni­tive Fit­ness and the Mature Work­force trends.

Q. I read so many con­flict­ing things I don’t know where to start.
A. You are not alone. We should all be aware that It is Not Only Cars That Deserve Good Main­te­nance: Brain Care 101.

Q. How can my orga­ni­za­tion deliver brain fit­ness activ­i­ties as a com­mu­nity ser­vice?
A. These arti­cles will pro­vide good guide­lines and ideas: Retool­ing Use It or Lose It , and Pub­lic Libraries: Community-Based Health Clubs for the Brain.

Q. Every­one seems obsessed with brain games. What about med­i­ta­tion?
A. Check out Yes, You Can Build Willpower, and Mind­ful­ness Med­i­ta­tion in Schools.

Q. Are software-based cog­ni­tive inter­ven­tions effec­tive?
A. As a cat­e­gory, it cer­tainly seems so, as long as we ask the right ques­tions, For Whom, For What?. For exam­ple, did you see this Sci­ence paper on how Cog­ni­tive Train­ing Can Influ­ence Dopamine Sys­tem?.

Q. What about the trade-off between time invested vs ben­e­fits real­ized.
A. Effi­ciency and replic­a­bil­ity of cog­ni­tive and brain-based out­comes seem to be, in fact, the strongest points of struc­tured cog­ni­tive inter­ven­tions. They seem to max­i­mize the Cog­ni­tive Value of your Men­tal Work­out.

Q. It some­times looks like the whole field came out of nowhere, due to Nin­tendo Brain Age’s suc­cess, so we can’t be talk­ing about some­thing seri­ous.
A: Nin­tendo did indeed cre­ate con­sumer aware­ness (for a prod­uct with lit­tle evi­dence) but “brain train­ing” has solid roots in neu­ropsy­chol­ogy and cog­ni­tive neu­ro­science, as you can read in our inter­view with Elkhonon Gold­berg.

Q. What about neu­ro­feed­back?
A. After years of much clin­i­cal use and lit­tle solid evi­dence, sev­eral impor­tant tri­als have been pub­lished since 2009, show­ing how neu­ro­feed­back can help diag­nose and treat ADHD patients, for exam­ple.

Q. How can one improve mem­ory?
A. Well, the answer deserves a whole book, but we can offer some Tips to Improve Mem­ory includ­ing Sleep, Prac­tice and Test­ing.

Q. How can I choose one among the num­ber of prod­ucts mak­ing mem­ory and brain claims?
A. We sug­gest you use this Eval­u­a­tion check­list, and con­sider read­ing our con­sumer guide/ book.

Q. Any gen­eral tips for edu­ca­tors and life­long learn­ers?
A. Indeed, here you have these 10 Brain Tips to Teach and Learn.

Q. How can I keep track of all the new trends, com­pa­nies and prod­ucts? Our health system/ insurer/ senior community/ ven­ture firm/ com­pany needs to make good deci­sions.
A. Well, that’s why we pub­lish mar­ket research, such as the one sum­ma­rized in this Info­graphic: State of the Mar­ket 2009 and also recently launched a pro­fes­sional Net­work for Brain Fit­ness Inno­va­tion.

Q: Thank you for all the infor­ma­tion you provide…but what I want more of is… brain teasers!
A. Under­stood. We will make sure to offer more, but you can try, right now, these Top 50 Brain Teasers and con­tinue with more recent puz­zles and brain games.

Here you have the March edi­tion of our monthly newslet­ter cov­er­ing cog­ni­tive health and brain fit­ness top­ics. Please remem­ber that you can sub­scribe to receive this Newslet­ter by email, using the box at the top of this page. I know I am biased — but do believe this Newslet­ter issue might well be our best so far. I hope you find the time to enjoy it!

Bird’s Eye View

Brain Fit­ness Sur­vey: Over 2,000 thought­ful responses to our Jan­u­ary sur­vey (Thank You!) rein­force the need for pub­lic aware­ness ini­tia­tives and qual­ity infor­ma­tion to help eval­u­ate and nav­i­gate lifestyle and prod­uct claims, as well as the need for more research, an expanded health­care cul­ture, as more. Given this con­text, we are pub­lish­ing The Sharp­Brains Guide to Brain Fit­ness in May 2009, a book with 18 Inter­views with Sci­en­tists, Prac­ti­cal Advice, and Prod­uct Reviews, in addi­tion to our annual mar­ket report for pro­fes­sion­als and exec­u­tives (to be pub­lished in April). If you have ideas to help us pro­mote the book, please reply to this email and let us know!

Life­long Learning

Here you have the pre­sen­ta­tion I deliv­ered on Tues­day at ETech 2009 (this year’s O’Reilly Emerg­ing Tech­nol­ogy Conference):

Emerg­ing Research and Tech­nol­ogy for Life Hacking/ Brain Training

(click to open pre­sen­ta­tion in new window)

Descrip­tion: Life hack­ing. Brain train­ing. They are one and the same. The brain’s frontal lobes enable our goal-oriented behav­ior, sup­port­ing exec­u­tive func­tions, such as decision-making, atten­tion, emo­tional self-regulation, goal-setting, and work­ing mem­ory. These func­tions can be enhanced with tar­geted prac­tice  such as life hack­ing. This ses­sion will pro­vide an overview of the cog­ni­tive neu­ro­science under­pin­ning life hack­ing, and review the state-of-the-art of non-invasive tools for brain train­ing: neu­ro­feed­back, biofeed­back, soft­ware appli­ca­tions, cog­ni­tive sim­u­la­tions, Tran­scra­nial Mag­netic Stim­u­la­tion, and plain-old meditation.

It was great to meet fel­low blog­gers and pre­sen­ters, such as Shel­ley Batts of Of Two Minds and Chris Patil of Ouroboros, and very inquisite and through­ful audi­ence mem­bers. Get­ting ready to speak at ASA/ NCOA and IHRSA next week!

Neu­ro­feed­back — also known as EEG Biofeed­back — is an approach for treat­ing ADHD in which indi­vid­u­als are pro­vided real-time feed­back on their brain­wave pat­terns and taught to alter their typ­i­cal EEG pat­tern to one that is con­sis­tent with a focused, atten­tive state. This is typ­i­cally done by col­lect­ing EEG data from indi­vid­u­als as they focus on stim­uli pre­sented on a com­puter screen. Their abil­ity to con­trol the stim­uli, for exam­ple, keep­ing the smile on a smi­ley face, is con­tin­gent on main­tain­ing the par­tic­u­lar EEG state being trained. Accord­ing to neu­ro­feed­back pro­po­nents, learn­ing how to do this dur­ing train­ing gen­er­al­izes to real world sit­u­a­tions and this results in improved atten­tion and reduced hyperactive/impulsive behavior.

Neu­ro­feed­back treat­ment for ADHD has been con­tro­ver­sial in the field for many years and remains so today. Although a num­ber of pub­lished stud­ies have reported pos­i­tive results many promi­nent ADHD researchers believe that prob­lems with the design of these stud­ies pre­clude con­clud­ing that neu­ro­feed­back is an effec­tive treat­ment. These lim­i­ta­tions have included the absence of ran­dom assign­ment, the lack of appro­pri­ate con­trol groups, raters who are not ‘blind’ to children’s treat­ment sta­tus, and small sam­ples. For addi­tional back­ground, you can find a recent review I wrote on exist­ing research sup­port for neu­ro­feed­back treat­ment of ADHD — along with links to exten­sive reviews of sev­eral recently pub­lished stud­ies -: How Strong is the Research Sup­port for Neu­ro­feed­back in Atten­tion Deficits?

- Results from a New Study of Neurofeedback -

Recently, a study of neu­ro­feed­back treat­ment for ADHD was pub­lished that addresses sev­eral lim­i­ta­tions that have under­mined prior research [Gevensleben, et al., (2009). Is neu­ro­feed­back an effi­ca­cious treat­ment for ADHD? A ran­dom­ized con­trolled clin­i­cal trial. Jour­nal of Child Psy­chol­ogy and Psychiatry.]

The study was con­ducted in Ger­many and began with 102 chil­dren aged 8 to 12. All had been care­fully diag­nosed with ADHD and approx­i­mately over 90% had never received med­ica­tion treat­ment. About 80% were boys. Chil­dren were ran­domly assigned to Read the rest of this entry »

Here you have Sharp­Brains’ 30 most pop­u­lar arti­cles, ranked by the num­ber of peo­ple who have read each arti­cle in 2008.

Please note that, since the first arti­cle already includes most of our most pop­u­lar brain teasers, we have excluded teasers from the rest of the rank­ing. (If those 50 are not enough for you, you can also try these brain teasers).

Like all psy­chi­atric dis­or­ders, ADHD is diag­nosed based on the pres­ence of par­tic­u­lar behav­ioral symp­toms that are judged to cause sig­nif­i­cant impair­ment in an individual’s func­tion­ing, and not on the results of a spe­cific test. In fact, recently pub­lished ADHD eval­u­a­tion guide­lines from the Amer­i­can Acad­emy of Pedi­atrics (AAP) explic­itly state that no par­tic­u­lar diag­nos­tic test should be rou­tinely used when eval­u­at­ing a child for ADHD.

While most ADHD experts would agree that no sin­gle test could or should be used in iso­la­tion to diag­nose ADHD, there are sev­eral impor­tant rea­sons why the avail­abil­ity of an accu­rate objec­tive test would be useful.

First, many chil­dren do not receive a care­ful and com­pre­hen­sive assess­ment for ADHD but are instead diag­nosed with based on eval­u­a­tion pro­ce­dures that are far from optimal.

Sec­ond, although AAP guide­lines indi­cate that spe­cific diag­nos­tic tests should not be rou­tinely used, many par­ents are con­cerned about the lack of objec­tive pro­ce­dures in their child’s eval­u­a­tion. In fact, many fam­i­lies do not pur­sue treat­ment for ADHD because the the absence of objec­tive eval­u­a­tion pro­ce­dures leads them to ques­tion the diag­no­sis. You can read a review of an inter­est­ing study on this issue at www.helpforadd.com/2006/january.htm

For these rea­sons an accu­rate and objec­tive diag­nos­tic test for ADHD could be of value in many clin­i­cal sit­u­a­tions. Two impor­tant con­di­tions would have to be met for such a test to be useful.

First, it would have to be highly sen­si­tive to Read the rest of this entry »

We are work­ing on improv­ing sev­eral sec­tions of our web­site, espe­cially our Resources sec­tion. It will look much bet­ter in a few days. Our first step has been to re-organize our Neu­ro­science Inter­view Series, and below you have how it looks today.

(Note: neu­ro­feed­back is a form of biofeed­back that mea­sures brain waves and that, accord­ing to prac­ti­tion­ers, pro­vides good “brain train­ing” for spe­cific clin­i­cal con­di­tions).
A few weeks ago Dr. David Rabiner wrote a great post on How Strong is the Research Sup­port for Neu­ro­feed­back in Atten­tion Deficits?, con­clud­ing that

- “It is for these rea­sons that neu­ro­feed­back is under­stand­ably regarded as an unproven treat­ment approach for ADHD at this time by many ADHD researchers.

- How­ever, these stud­ies do pro­vide a solid basis for sug­gest­ing that if par­ents choose to pur­sue neu­ro­feed­back for their child, there is a rea­son­able chance that their child will ben­e­fit even though we can’t be sure that it is the spe­cific EEG train­ing that is respon­si­ble for the ben­e­fits. Thus, although the effi­cacy of neu­ro­feed­back has yet to be con­clu­sively con­firmed in a ran­dom­ized, placebo-controlled trial, it is impor­tant to place this lim­i­ta­tion in the con­text of the sup­port­ive research evi­dence that has been accumulated.

A CDC report esti­mated that, in 2003, 4.4 mil­lion youth ages 4–17 lived with diag­nosed ADHD, and 2.5 mil­lion of them were receiv­ing med­ica­tion treat­ment. Now, which is the core deficit under­ly­ing ADHD-so that treat­ments really address it? and how are ADHD and brain devel­op­ment related? Keep reading…

ADHD & the Nature of Self-Control — Revis­it­ing Barkley’s The­ory of ADHD

— By David Rabiner, Ph.D

As implied in the title of his book, ADHD and the Nature of Self-Control, Dr. Barkley argues that the fun­da­men­tal deficit in indi­vid­u­als with ADHD is one of self-control, and that prob­lems with atten­tion are a sec­ondary char­ac­ter­is­tic of the disorder.

Dr. Barkley empha­sizes that dur­ing the course of devel­op­ment, con­trol over a child’s behav­ior grad­u­ally shifts from exter­nal sources to being increas­ingly gov­erned by inter­nal rules and stan­dards. Con­trol­ling one’s behav­ior by inter­nal rules and stan­dards is what is meant by the term “self-control”.
