Chap­ter 4: Devel­op­ment and Growth.

The First 20 years.

Many par­ents, health care pro­fes­sion­als, and edu­ca­tors agree that there is a press­ing need to develop effec­tive treat­ments for ADHD to com­ple­ment or sub­sti­tute for tra­di­tional med­ica­tion and behav­ior ther­apy approaches. This is because such treat­ments do not work for every­one, impor­tant dif­fi­cul­ties often remain even when these treat­ments are effec­tive, and evi­dence for the long-term ben­e­fits of these treat­ments remains less com­pelling than one would like. In addi­tion, in the case of med­ica­tion treat­ment, some indi­vid­u­als expe­ri­ence intol­er­a­ble side effects and many have con­cerns about tak­ing ADHD med­ica­tion for an extended period.

One alter­na­tive approach to treat­ing ADHD has relied on the use of Com­pound Herbal Prepa­ra­tions (CHP) derived from tra­di­tional Chi­nese med­i­cine. Prac­ti­tion­ers of this approach believe that such prepa­ra­tions have impor­tant cog­ni­tive enhanc­ing prop­er­ties because they sup­ply essen­tial nutri­ents, fatty acids, phos­pho­lipids, amino acids, B vit­a­mins, min­er­als, and other micronu­tri­ents that are impor­tant for opti­mal brain growth and devel­op­ment. As a treat­ment for ADHD, the idea is that many indi­vid­u­als with ADHD have defi­cien­cies in essen­tial nutri­ents that com­pro­mise healthy brain devel­op­ment and result in ADHD symp­toms. Pro­vid­ing these nutri­ents via an appro­pri­ately pre­pared herbal com­pound thus has the poten­tial to be ther­a­peu­tic and reduce these symptoms.

This idea was tested recently in a randomized-controlled trial of a spe­cific CHP for chil­dren with ADHD [Katz, Kol-Degani, & Kav-Venaki (2010). A com­pound herbal prepa­ra­tion (CHP) in the treat­ment of ADHD: A ran­dom­ized con­trolled trial. Jour­nal of Atten­tion Dis­or­ders. Pub­lished online on March 12, 2010.] Par­tic­i­pants were 120 6–12 year-old chil­dren newly diag­nosed with ADHD based on a com­pre­hen­sive diag­nos­tic eval­u­a­tion. These chil­dren were all eval­u­ated at the Sheba Med­ical Cen­ter, one of the largest university-affiliated ter­tiary care cen­ters in Israel.

(Editor´s note: Dr. David Rabiner, author of this arti­cle, pre­vi­ously reviewed a 2005 meta-analysis whose find­ings need to be kept in mind to con­tex­tu­al­ize this new study. In the arti­cle Dietary Inter­ven­tion for ADHD: A Meta-Analysis, Dr. Rabiner con­cluded that “Results from this meta-analysis pro­vide strong evi­dence that the behav­ior of chil­dren with ADHD can be made worse by dietary fac­tors, and that elim­i­nat­ing AFCs from their diets will, on aver­age, result in behav­ioral improve­ments. This result is con­sis­tent with with accu­mu­lat­ing evi­dence that neu­robe­hav­ioral tox­i­c­ity may result from a wide vari­ety of dis­trib­uted chemicals.”)

The cur­rent price is $379, with a 15% dis­count if you use code “sharp09” (with­out quo­ta­tion) when you reg­is­ter Here. Details: June 11-12th at the Hyatt Har­bor­side Hotel in Boston, MA.

Bilin­gual Babies Get Head Start — Before They Can Talk:

- “Unlike the mono­lin­gual group, the bilin­gual group was able to suc­cess­fully learn a new sound type and use it to pre­dict where each char­ac­ter would pop up…The bilin­gual babies’ skill applies to more than just switch­ing between lan­guages. Mehler likened this appar­ently enhanced cog­ni­tive abil­ity to a brain select­ing “the right tool for the right operation”—also called exec­u­tive function.”

- “In this basic process, the brain, ever flex­i­ble, nim­bly switches from one learned response to another as sit­u­a­tions change…Monolingual babies hone this abil­ity later in their young lives, Mehler suggests.”

At a time when edu­ca­tors are pre­oc­cu­pied with stan­dards, test­ing, and the bot­tom line, some researchers sug­gest the arts can boost stu­dents’ test scores; oth­ers aren’t con­vinced. Karin Evans asks, What are the arts good for?

—
When poet and national endow­ment for the Arts Chair­man Dana Gioia gave the 2007 Com­mence­ment Address at Stan­ford Uni­ver­sity, he used the occa­sion to deliver an impas­sioned argu­ment for the value of the arts and arts education.

“Art is an irre­place­able way of under­stand­ing and express­ing the world,” said Gioia. “There are some truths about life that can be expressed only as sto­ries, or songs, or images. Art delights, instructs, con­soles. It edu­cates our emotions.”

For years, arts advo­cates like Gioia have been mak­ing sim­i­lar pleas, stress­ing the intan­gi­ble ben­e­fits of the arts at a time when many Amer­i­cans are pre­oc­cu­pied with a market–driven cul­ture of enter­tain­ment, and schools are con­sumed with meet­ing fed­eral stan­dards. Art brings joy, these advo­cates say, or it evokes our human­ity, or, in the words of my 10–year–old daugh­ter, “It cools kids down after all the other hard stuff they have to think about.”

Bol­ster­ing the case for the arts has become increas­ingly nec­es­sary in recent years, as school bud­get cuts and the move toward stan­dard­ized test­ing have pro­foundly threat­ened the role of the arts in schools. Under the No Child Left Behind Act, passed in 2002, the fed­eral gov­ern­ment started assess­ing school dis­tricts by their stu­dents’ scores on read­ing and math­e­mat­ics tests.

As a result, accord­ing to a study by the Cen­ter on Edu­ca­tion Pol­icy, school dis­tricts across the United States increased the time they devoted to tested subjects—reading/language arts and math—while cut­ting spend­ing on non–tested sub­jects such as the visual arts and music. The more a school fell behind, by NCLB stan­dards, the more time and money was devoted to those tested sub­jects, with less going to the arts. The National Edu­ca­tion Asso­ci­a­tion has reported that the cuts fall hard­est on schools with high num­bers of minor­ity children.

And the sit­u­a­tion is likely to worsen as state bud­gets get even tighter. Already, in a round of fed­eral edu­ca­tion cuts for 2006 and 2007, arts edu­ca­tion nation­ally was slashed by $35 mil­lion. In 2008, the New York City Depart­ment of Education’s annual study of Read the rest of this entry »

Round-up of recent arti­cles on neu­ro­science, brain devel­op­ment and cog­ni­tive health:

Encephalon 68: A car­ni­val of neu­ro­science:

Chris hosts a great col­lec­tion of neu­ro­science and psy­chol­ogy posts in his sig­na­ture Q&A style.

Bilin­gual Babies Get Head Start — Before They Can Talk:

- Unlike the mono­lin­gual group, the bilin­gual group was able to suc­cess­fully learn a new sound type and use it to pre­dict where each char­ac­ter would pop up.

- The bilin­gual babies’ skill applies to more than just switch­ing between lan­guages. Mehler likened this appar­ently enhanced cog­ni­tive abil­ity to a brain select­ing “the right tool for the right oper­a­tion” also called exec­u­tive function.

- In this basic process, the brain, ever flex­i­ble, nim­bly switches from one learned response to another as sit­u­a­tions change.

- Mono­lin­gual babies hone this abil­ity later in their young lives, Mehler suggests.”

Study shows how kids’ stress hurts mem­ory:

“Now, research is pro­vid­ing what could be cru­cial clues to explain how child­hood poverty trans­lates into dim­mer chances of suc­cess: Chronic stress from grow­ing up poor appears to have a direct impact on the brain, leav­ing chil­dren with impair­ment in at least one key area — work­ing memory.”

Return­ing troops get­ting tested for brain injuries:

- “More than 150,000 ser­vice mem­bers from the Marines, Air Force, Army and Navy have under­gone the test­ing that became manda­tory last year. Those who suf­fer a con­cus­sion or sim­i­lar head injury will get a follow-up test.”

Dia­betes ‘impact on brain power’:

- “Fail­ure to con­trol type 2 dia­betes may have a long-term impact on the brain, research has suggested.

- Lead researcher Dr Jackie Price said: “Either hypos lead to cog­ni­tive decline, or cog­ni­tive decline makes it more dif­fi­cult for peo­ple to man­age their dia­betes, which in turn causes more hypos.

- “A third expla­na­tion could be that a third uniden­ti­fied fac­tor is caus­ing both the hypos and the cog­ni­tive decline.”

In April 2008, Bay­crest, a lead­ing research insti­tute focused on aging and brain func­tion, received $10-million from the Ontario Gov­ern­ment to cre­ate a ground­break­ing Cen­tre for Brain Fit­ness. Its stated goal was to “develop and com­mer­cial­ize a range of prod­ucts designed to improve the brain health of aging Ontar­i­ans and oth­ers around the world”.

“Our gov­ern­ment is proud to sup­port Bay­crest and its invalu­able work, which is already lead­ing to the dis­cov­ery of impor­tant new tools and approaches to treat­ing brain dis­eases asso­ci­ated with aging,” said Min­is­ter of Research and Inno­va­tion, John Wilkinson.

We have Baycrest’s CEO with us today, to explore why Ontario and Bay­crest chose to become pio­neers in this area, and dis­cuss some of the main oppor­tu­ni­ties, and chal­lenges. Dr. William E. Reich­man is Pres­i­dent and CEO of Bay­crest. Dr. Reich­man, an internationally-known expert in geri­atric men­tal health and demen­tia, is also Pro­fes­sor of Psy­chi­a­try on the Fac­ulty of Med­i­cine at the Uni­ver­sity of Toronto.

Alvaro Fer­nan­dez: Bill, thank you for your time. Let me start by ask­ing, given that you just spoke at the recent Con­sumer Elec­tronic Show, what do you make of the grow­ing brain fit­ness field?

Bill Reich­man: it looks like a clas­sic exam­ple of a very promis­ing but still early stage field – a lot of oppor­tu­nity and enthu­si­asm, but also a lot of prod­uct claims that are not backed by solid research. Think about the phys­i­cal fit­ness anal­ogy: even today, after decades of progress, you still see peo­ple buy­ing research-based prod­ucts such as tread­mills but also all types of ran­dom machines they see on TV and have not been sub­ject to any val­i­da­tion. Sim­i­larly, con­sumers today do not know what to make of grow­ing brain fit­ness claims. As another speaker pointed out, for the indus­try to ful­fill its promise, it will need to be care­ful with research and claims, not to end up like the nutraceu­ti­cals category.

By the way, let me rec­og­nize that the work you are doing with Sharp­Brains reports and your web­site is very impor­tant to offer qual­ity information.

Thank you. Let’s step back for a moment. Tak­ing a, say, 10 years view, what is the main oppor­tu­nity that technology-based brain fit­ness can offer to society?

First of all, let me say that I think we have an oppor­tu­nity to make major progress in Brain Health in the XXI cen­tury, sim­i­lar to what hap­pened with Car­dio­vas­cu­lar Health in the XX, and tech­nol­ogy will play a cru­cial role.

Given the rapid advances we are wit­ness­ing today in the research and tech­nol­ogy are­nas, I feel con­fi­dent in say­ing that in less than 10 years we will have both valid and reli­able assess­ments of cog­ni­tive func­tions, that will be used both by Read the rest of this entry »

Dr. Robert Syl­wester is an edu­ca­tor of edu­ca­tors, hav­ing received mul­ti­ple awards dur­ing his long career as a mas­ter com­mu­ni­ca­tor of the impli­ca­tions of brain sci­ence research for edu­ca­tion and learn­ing. He is the author of sev­eral books and many jour­nal arti­cles, and mem­ber of our Sci­en­tific Advi­sory Board. His most recent book is The Ado­les­cent Brain: Reach­ing for Auton­omy (Cor­win Press, 2007). He is an Emer­i­tus Pro­fes­sor of Edu­ca­tion at the Uni­ver­sity of Oregon.

I am hon­ored to inter­view him today.

Alvaro Fer­nan­dez: Let’s start with that eter­nal source of debate. What do we know about the respec­tive roles of genes and our envi­ron­ment in brain devel­op­ment?

Robert Syl­wester: Genetic and envi­ron­men­tal fac­tors both con­tribute to brain mat­u­ra­tion. Genet­ics prob­a­bly play a stronger role in the early years, and the envi­ron­ment plays a stronger role in later years. Still the mother’s (envi­ron­men­tal) use of drugs dur­ing the preg­nancy could affect the genet­ics of fetal brain devel­op­ment, and some adult ill­nesses, such as Huntington’s Dis­ease, are genet­i­cally triggered.

Nature and nur­ture both require the sig­nif­i­cant con­tri­bu­tions of the other in most devel­op­men­tal and main­te­nance func­tions. We typ­i­cally think of envi­ron­men­tal fac­tors as things that hap­pen to us, over which we have lit­tle control.

Can’t our own deci­sions have an effect in our own brain devel­op­ment? For exam­ple, what if I choose a career in invest­ment bank­ing, vs. one in jour­nal­ism or teaching?

We make our own career deci­sions in life, and most of us make a com­bi­na­tion of good and bad deci­sions, which influ­ence our brain’s maturation.

My father was very unusual in his career tra­jec­tory in that he worked at one place through­out his entire adult life, and died three months after he retired at 91. I’ve always thought that it’s a good idea to make a change every ten years or so and do some­thing dif­fer­ent either within the same orga­ni­za­tion or to move to another one.

It’s just as good for orga­ni­za­tions to have some staff turnover as it is for staff to move to new chal­lenges. The time to leave one posi­tion for another is while you and your employer are Read the rest of this entry »
