Posit Science, Nintendo Brain Age, and Brain Training Topics

A few col­leagues referred me over the week­end to a very nice arti­cle at busi­ness pub­li­ca­tion Port­fo­lio.

While the arti­cle does an excel­lent job at intro­duc­ing the read­er to the con­cept and promise of com­put­er­ized cog­ni­tive assess­ments, it also con­tributes to the mythol­o­gy of “Brain Age”. MRI scan neuroimaging

Let’s first take a look at the arti­cle How Smart Are You: The busi­ness of assess­ing cog­ni­tion and mem­o­ry is mov­ing from test­ing brain-impaired patients to assess­ing healthy peo­ples’ brains online.

A cou­ple of quotes:

- “Cog­ni­tive Drug Research is one a hand­ful of busi­ness­es, most of them out­side of the U.S., that work with phar­ma­ceu­ti­cal com­pa­nies to test how new drugs for every­thing from nico­tine addic­tion to Alzheimer’s dis­ease affect the mind’s abil­i­ty to remem­ber things, make deci­sions, and ana­lyze information.”

- “Cog­ni­tive tests have been around for a cen­tu­ry as exam­i­na­tions tak­en with paper and pen­cil. In the 1970s and ’80s the tests shift­ed to com­put­ers, Cog­ni­tive Drug Research founder Kei­th Wesnes says.

So far, so good. In fact, one of the key high­lights from the mar­ket report we released in March was that “Large-scale, ful­ly-auto­mat­ed cog­ni­tive assess­ments are being used in a grow­ing num­ber of clin­i­cal tri­als. This opens the way for the devel­op­ment of inex­pen­sive con­sumer-fac­ing, base­line cog­ni­tive assess­ments.” And we pro­filed a few lead­ing com­pa­nies in the space: Brain Resource Com­pa­ny, Cog­ni­tive Drug Research, CNS Vital Signs and CogState.

Now, the arti­cle is accom­pa­nied by a 5–7 minute quick test that promis­es to give us our “Brain Age”. And this does­n’t come from Nin­ten­do, but from Cog­ni­tive Drug Research, a respect­ed sci­ence-based company.

Brain Fitness and SharpBrains.com in the Press

Fitness TrainerGrow­ing media atten­tion on the brain fit­ness field. At least on the “Healthy Aging” seg­ment (I pre­dict the media with catch up soon with devel­op­ments in oth­er areas, from cog­ni­tive train­ing for kids and adults with ADD/ ADHD to stroke and TBI reha­bil­i­ta­tion, to peak per­for­mance for cor­po­rate training).

First, a superb arti­cle by Leslie Walk­er at the Wash­ing­ton Post: Cross-Train­ing Your Brain to Main­tain Its Strength

Quotes:  “A grow­ing body of research sug­gests that men­tal activ­i­ty in mid­dle age and ear­li­er can help lat­er in life. As a result, Web sites such as HappyNeuron.com are spring­ing up to offer online games to peo­ple of all ages, while blogs like SharpBrains.com pro­vide com­men­tary on the fledg­ling indus­try.” (Note: we can also pro­vide com­men­tary on the commentary!)

“Peo­ple who engage in very chal­leng­ing tasks — not just in work but dur­ing leisure activ­i­ties such as read­ing, cross­word puz­zles, bridge, chess and trav­el — tend to slow down their men­tal aging process very sig­nif­i­cant­ly,” says Breznitz, who is also a mem­ber of Israel’s leg­is­la­ture and has devel­oped a brain-train­ing pro­gram called MindFit.”

“Also con­tribut­ing to the brain work­out boom are state-of-the-art imag­ing tech­niques that have allowed sci­en­tists to val­i­date a the­o­ry devel­oped decades ago. By tak­ing detailed pic­tures of brain neu­rons, sci­en­tists watch parts of the brain that had seemed dor­mant light up and assume new respon­si­bil­i­ties in response to stim­uli. The­o­ret­i­cal­ly, this means brain decay can be halt­ed or even reversed.”

“The brain is con­stant­ly rewiring and recal­i­brat­ing itself in response to what you do,” says Hen­ry Mah­ncke, whComputer Classroomo holds a PhD in neu­ro­science and is vice pres­i­dent of Posit Sci­ence, the San Fran­cis­co devel­op­er of the Brain Fit­ness soft­ware. “It remakes itself into a more effi­cient oper­a­tion to do the things you ask it to do.”

Com­ments: the arti­cle touch­es many key points. I espe­cial­ly enjoy the quote “To be effec­tive, sci­en­tists say men­tal activ­i­ty must become pro­gres­sive­ly more chal­leng­ing. Oth­er­wise, the brain adjusts and learns to per­form repet­i­tive tasks with less effort”, a key mes­sage I make often in my lec­tures to explain why well-designed pro­grams can be more effec­tive than doing cross­word puz­zle num­ber 512,789. The arti­cle also relates how many retire­ment com­mu­ni­ties and senior cen­ters and indi­vid­u­als are try­ing out the new brain fit­ness pro­grams com­ing to mar­ket, and shows some healthy skep­ti­cism on the state of the research. Now, this is an invi­ta­tion to the reporter to inter­view neu­ropsy­chol­o­gist Dr. Elkhonon Gold­berg to get the full pic­ture of the sci­ence behind the field, since these pro­grams haven’t appeared in a vac­u­um. Our 10-Ques­tion Eval­u­a­tion Check­list can pro­vide use­ful guid­ance to any­one con­sid­er­ing a program.

Boomers use online brain games to stave off demen­tia (Account­ing­Web)

Quotes: “The Inter­net offers a pletho­ra of brain games for those who don’t sub­scribe to a dai­ly news­pa­per or don’t want to pur­chase games. AARP, for exam­ple, offers plen­ty of free games on its site. More games appear at SharpBrains.com, includ­ing a page that con­tains the Top Ten Neu­ro­science Brain­teasers, and you can sign up to have the Col­lege Board e‑mail you the SAT ques­tion of the day.”

“The gen­er­a­tion that refus­es to age is not going to sit back and wait for Alzheimer’s Dis­ease and oth­er signs of demen­tia to take hold. Instead, savvy Baby Boomers are expand­ing their minds (no, not the way they did in the 60s) with the aid of the com­put­er, puz­zles, and games.
