Work­ing mem­ory is our abil­ity to store and manip­u­late infor­ma­tion for a brief time. It is typ­i­cally mea­sured by dual-tasks, where the indi­vid­ual has to remem­ber an item while simul­ta­ne­ously pro­cess­ing a some­times unre­lated piece of infor­ma­tion. A widely used work­ing mem­ory task is the read­ing span task where the indi­vid­ual reads a sen­tence, ver­i­fies it, and then recalls the final word. Indi­vid­ual dif­fer­ences in work­ing mem­ory per­for­mance are closely related to a range of aca­d­e­mic skills such as read­ing, spelling, com­pre­hen­sion, and math­e­mat­ics. Cru­cially, there is emerg­ing research that work­ing mem­ory pre­dicts learn­ing out­comes inde­pen­dently of IQ. One expla­na­tion for the impor­tance of work­ing mem­ory in aca­d­e­mic attain­ment is that because it appears to be rel­a­tively unaf­fected by envi­ron­men­tal influ­ences, such as parental edu­ca­tional level and finan­cial back­ground, it mea­sures a student’s capac­ity to acquire knowl­edge rather than what they have already learned.

How­ever lit­tle is known about the con­se­quences of low work­ing mem­ory capac­ity per se, inde­pen­dent of other asso­ci­ated learn­ing dif­fi­cul­ties. In par­tic­u­lar, it is not known either what pro­por­tion of stu­dents with low work­ing mem­ory capac­i­ties has sig­nif­i­cant learn­ing dif­fi­cul­ties or what their behav­ioral char­ac­ter­is­tics are. The aim of a recent study pub­lished in Child Devel­op­ment (ref­er­ence below) was to pro­vide the first sys­tem­atic large-scale exam­i­na­tion of the cog­ni­tive and behav­ioral char­ac­ter­is­tics of school-aged stu­dents who have been iden­ti­fied solely on the basis of very low work­ing mem­ory scores.

In screen­ing of over 3000 school-aged stu­dents in main­stream schools, 1 in 10 was iden­ti­fied as hav­ing work­ing mem­ory dif­fi­cul­ties. There were sev­eral key find­ings regard­ing their cog­ni­tive skills. The first is that the major­ity of them per­formed below age-expected lev­els in read­ing and math­e­mat­ics.

My apolo­gies for not writ­ing in a few days…the Global Agenda Sum­mit in Dubai has required all my atten­tion — I will sum­ma­rize the great expe­ri­ence when I land back in San Fran­cisco tomor­row night.

The con­cepts of night and day do become chal­leng­ing when work­ing for a few days in a place with a 12-hour time dif­fer­ence with one’s home base. Sleep is indeed very impor­tant to main­tain top cog­ni­tive shape…which leads me to a fas­ci­nat­ing news announcement:

Health insur­ance firms offer­ing online cog­ni­tive ther­apy for insom­nia (Los Ange­les Times)

- “help­ing con­sumers get a good night’s sleep has become a pri­or­ity for most of the top-tier U.S. health insur­ance com­pa­nies, includ­ing Well­Point, Aetna, Cigna, Kaiser Per­ma­nente and sev­eral Blue Cross plans. Their new pro­grams don’t involve sleep­ing pills. Instead, insur­ers are advo­cat­ing the use of cog­ni­tive behav­ior ther­apy. Tra­di­tion­ally, the ther­apy has been done largely through face-to-face ses­sions, but many of the pro­grams are now avail­able online.”

The Wall Street Jour­nal had a very inter­est­ing arti­cle yes­ter­day, titled To Be Young and Anxiety-Free, focused on the value of cog­ni­tive behav­ioral ther­apy to help chil­dren with high lev­els of anx­i­ety learn how too cope bet­ter and pre­vent the snow­ball sce­nario, when that anx­i­ety grows and spi­rals out of con­trol result­ing in depres­sion and similar

- “…new research show­ing that treat­ing kids for anx­i­ety when they are young may help pre­vent the devel­op­ment of more seri­ous men­tal ill­nesses, includ­ing depres­sion and more debil­i­tat­ing anx­i­ety disorders.”

- “Of course, most kids have fears with­out hav­ing a full-blown anx­i­ety dis­or­der. And some anx­i­ety is healthy: It makes sense, for exam­ple, to be a lit­tle ner­vous before a big test. Doc­tors and psy­chol­o­gists do cau­tion that the increased focus on child­hood anx­i­ety could lead to an over­diag­no­sis of the prob­lem. What makes anx­i­ety a true ill­ness is when it inter­feres with nor­mal func­tion­ing or causes seri­ous emo­tional and phys­i­cal distress.”

- “But the use of anti­de­pres­sants in chil­dren has come under fire because Read the rest of this entry »

We have talked about the value of med­i­ta­tion before (see Mind­ful­ness and Med­i­ta­tion in Schools), as a form of well-directed men­tal exer­cise than can help train atten­tion and emo­tional self-regulation.  Which other stud­ies have shown how it strength­ens spe­cific parts of the brain, mainly in the frontal lobe.

Dr. Rabiner shares with us, below, an excel­lent review of a new study that ana­lyzes the ben­e­fits of mind­ful­ness for ado­les­cents and adults with atten­tion deficits. He writes that “although this is clearly a pre­lim­i­nary study, the results are both inter­est­ing and encouraging.”

Does Mind­ful­ness Med­i­ta­tion Help Adults & Teens with ADHD

– By Dr. David Rabiner

Although med­ica­tion treat­ment is effec­tive for many indi­vid­u­als with ADHD, includ­ing ado­les­cents adults, there remains an under­stand­able need to explore and develop inter­ven­tions that can com­ple­ment or even sub­sti­tute for med­ica­tion. This is true for a vari­ety of rea­sons includ­ing:
1) Not all adults with ADHD ben­e­fit from med­ica­tion.
2) Among those who ben­e­fit, many have resid­ual dif­fi­cul­ties that need to be addressed via other means.
3) Some adults with ADHD expe­ri­ence adverse effects that pre­vent them from remain­ing on medication.

What stresses you out ?

What­ever it is, how you respond to it may have more con­se­quences than you think. Let me show you how.

Recap­ping from last months arti­cle (see Stress and Neural Wreck­age: Part of the Brain Plas­tic­ity Puz­zle)…our bod­ies are a com­plex bal­anc­ing act between sys­tems work­ing full time to keep us alive and well. Any change which threat­ens this bal­ance can be referred to as stress. Cor­ti­sol, a key com­po­nent of the stress response, does an excel­lent job of allow­ing us to adapt to most stres­sors which last more than a cou­ple of min­utes. How­ever, hav­ing to endure a high stres­sor for longer than about 30 min­utes to an hour neg­a­tively impacts the brain in var­i­ous ways.

Dr. Adrian Preda, our newest Expert Con­trib­u­tor, writes today the first in a series of thought-provoking arti­cles, chal­leng­ing us to think about phys­i­cal exer­cise as the best and most unap­pre­ci­ated form of “brain exer­cise”. A superb article.

And one thing is clear, he points out: “the brain really likes it when it’s asked to be “active”. Pas­sive audi­ences, which are spoon fed infor­ma­tion, score less well when tested on reten­tion and under­stand­ing of the pre­sented mate­r­ial than audi­ences that were kept engaged through the process.”

So, will you write a com­ment below and con­tribute to an engag­ing con­ver­sa­tion? Thoughts? reac­tions? ques­tions?

Brain Lessons Part 1

– By Adrian Preda, M.D.

Let me start with a list of com­mon biases: expen­sive is bet­ter than cheap, free is of dubi­ous value (why would then be free?), rare is likely to be valu­able, and while new is bet­ter than old, ancient is always best. Which explains a com­mon sce­nario that is reen­acted about twice a week in my office. It starts like this: a patient shows me a fancy look­ing bot­tle of the brain sup­ple­ment of the week: ancient roots with obscure names mixed together in another novel com­bi­na­tion which you can exclu­sively find in that one and only store (rar­ity oblige!). And not to for­get: it ain’t cheap either! Of course, there it is, the per­fect the recipe for suc­cess: ancient yet new, rare and expen­sive. It got to be good! But is it, really?

Here you have a col­lec­tion of recent news cov­er­age on brain heath, fit­ness and train­ing topics:

1– Great Mem­ory Spe­cial in National Geo­graphic, including

- Inter­ac­tive 3D map of the brain

- Mem­ory Game

2– Fas­ci­nat­ing What the Bea­t­les Gave Sci­ence, by Sharon Beg­ley at Newsweek

- “Even in novices, med­i­ta­tion leaves its mark. An eight-week course in com­pas­sion med­i­ta­tion, in which vol­un­teers focus on the wish that all beings be free from suf­fer­ing, shifted brain activ­ity from the right pre­frontal cor­tex to the left, a pat­tern asso­ci­ated with a greater sense of well-being.”

3– One of the best edi­tions of Sci­en­tific Amer­i­can Mind

- Solv­ing the IQ Puz­zle “The 20th cen­tury saw the Flynn effect: mas­sive gains in IQ from one gen­er­a­tion to another. Now Flynn explains why”

- Anx­i­ety and Alzheimer- A life­time of stress could lead to mem­ory prob­lems and dis­ease: “Over a period of up to 12 years, vol­un­teers who were anxiety-prone had a 40 per­cent higher risk of devel­op­ing mild cog­ni­tive impair­ment than more easy­go­ing indi­vid­u­als did. Mild cog­ni­tive impair­ment is thought to be a pre­cur­sor for Alzheimer’s.”

4– Exer­cise builds strong brains, too — USATODAY.com

- “Phillip Tom­porowski, a study co-author and exer­cise psy­chol­o­gist at the Uni­ver­sity of Geor­gia in Athens, says exer­cise “may well improve the under­ly­ing men­tal processes that are involved in a lot of behav­iors and aca­d­e­mic tasks.”

5– Daily com­puter game boosts maths– BBC, report­ing pre­lim­i­nary results from a small pilot

- “Play­ing a daily com­puter game has helped a class of pri­mary school chil­dren improve their maths and con­cen­tra­tion, a study says.”

6– ADHD and Brain Devel­op­ment– Wash­ing­ton Post

- “Devel­op­ing more slowly in ADHD young­sters — the lag can be as much as three years — are brain regions that sup­press inap­pro­pri­ate actions and thoughts, focus atten­tion, remem­ber things from moment to moment, work for reward, and con­trol movement.”

Very nice Los Ange­les Times arti­cle on the grow­ing research behind, and accep­tance of, med­i­ta­tion in main­stream med­i­cine (through what is called Mindfulness-Based Stress Reduc­tion, or MBSR): Doctor’s orders: Cross your legs and say ‘Om’.

A few quotes:

- “It appears to work. In a new study, pub­lished in Octo­ber in the jour­nal Pain, Natalia Morone, an assis­tant pro­fes­sor of med­i­cine at the Uni­ver­sity of Pitts­burgh, tracked the effect of mind­ful­ness med­i­ta­tion on chronic lower back pain in adults 65 and older. The ran­dom­ized, con­trolled clin­i­cal trial found that the 37 peo­ple who par­tic­i­pated in an eight-week mind­ful­ness med­i­ta­tion pro­gram had sig­nif­i­cantly greater pain accep­tance and phys­i­cal func­tion than a sim­i­lar size con­trol group. Sub­se­quently, the con­trol group took the same eight-week pro­gram and had sim­i­lar results.”

- “As a med­i­ta­tor, I learned the value of being present and how that allows clar­ity in pro­cess­ing our daily lives,” Zeltzer said. “The clin­i­cal team sees chil­dren with chronic pain who are very dif­fi­cult to treat and have been to many other spe­cial­ists and feel dis­cour­aged by the time they come to us. I felt that learn­ing to med­i­tate would help the team feel a sense of bal­ance and equa­nim­ity in the face of the anx­i­ety and dis­tress brought to them by these patients and their families.”

- “SCIENTISTS have stud­ied the effects of med­i­ta­tion on pain for nearly three decades, ever since 1979, when MIT-trained micro­bi­ol­o­gist Jon Kabat-Zinn, pro­fes­sor emer­i­tus and founder of the Cen­ter for Mind­ful­ness at the Uni­ver­sity of Mass­a­chu­setts Med­ical Cen­ter, used mind­ful­ness med­i­ta­tion in a 10-week pro­gram to teach chronic pain patients how to cope. Kabat-Zinn’s 1990 best­seller, “Full Cat­a­stro­phe Liv­ing,” described the tech­nique he used — mindfulness-based stress reduc­tion, or MBSR.”
