The IMPACT study which we reported on in Decem­ber 2007, funded by Posit Sci­ence, con­ducted by the Mayo Clinic and USC Davis, has just announced pub­li­ca­tion at the Jour­nal of the Amer­i­can Geri­atrics Soci­ety. Ref­er­ence:

- Smith et al. A Cog­ni­tive Train­ing Pro­gram Designed Based on Prin­ci­ples of Brain Plas­tic­ity: Results from the Improve­ment in Mem­ory with Plasticity-based Adap­tive Cog­ni­tive Train­ing Study. Jour­nal of the Amer­i­can Geri­atrics Soci­ety, April 2009.

Com­puter Exer­cises Improve Mem­ory And Atten­tion, Study Sug­gests (Sci­ence Daily)

- “The Improve­ment in Mem­ory with Plasticity-based Adap­tive Cog­ni­tive Train­ing (IMPACT) study was funded by the Posit Sci­ence Cor­po­ra­tion, which owns the rights to the Brain Fit­ness Pro­gram, tested in the study.”

- “Of the 487 healthy adults over the age of 65 who par­tic­i­pated in a ran­dom­ized con­trolled trial, half used the Brain Fit­ness Pro­gram for 40 hours over the course of eight weeks. The Brain Fit­ness Pro­gram con­sists of six audio exer­cises done on a com­puter, and is intended to “retrain the brain to dis­crim­i­nate fine dis­tinc­tions in sound, and do it in a way that keeps the user engaged,” Zelin­ski explained.” The other half of par­tic­i­pants spent an equal amount of time learn­ing from edu­ca­tional DVDs fol­lowed by quizzes.

Com­ment: this is a very inter­est­ing study, in that it shows both that cog­ni­tive train­ing works, and that it doesn’t work.

Sharon Beg­ley, Newsweek’s sci­ence reporter, recently wrote that

- “With the nation’s 78 mil­lion baby boomers approach­ing the age of those dreaded ‘“where did I leave my keys?” moments, it’s no won­der the mar­ket for computer-based brain train­ing has shot up from essen­tially zero in 2005 to $80 mil­lion this year, accord­ing to the con­sult­ing firm SharpBrains.

- “Now comes the largest and most rig­or­ous study of a commercially-available train­ing pro­gram, and it shows that there is hope for aging brains. This morn­ing, at the meet­ing of the Geron­to­log­i­cal Soci­ety of Amer­ica, sci­en­tists are pre­sent­ing data show­ing that after eight weeks of daily one-hour ses­sions with Brain Fit­ness 2.0 from Posit Sci­ence, elderly vol­un­teers got mea­sur­ably bet­ter in their brain’s speed and accu­racy of processing.

We recently had the chance to inter­view Dr. Eliz­a­beth Zelin­ski of the Uni­ver­sity of South­ern Cal­i­for­nia Andrus Geron­tol­ogy Cen­ter, who led the IMPACT (Improve­ment in Mem­ory with Plasticity-based Adap­tive Cog­ni­tive Train­ing) Study Sharon Beg­ley refers to in the quote above.

First, some con­text on this study, which is by far the largest high-quality study of its kind. The study was prospec­tive, ran­dom­ized, con­trolled, and used a dou­ble blind trial. 524 healthy adults 65-year-old and over were divided into two groups. One received an hour a day of train­ing for eight to ten weeks, and the other spent the same amount of time watch­ing edu­ca­tional DVDs. The IMPACT study, funded by Posit Sci­ence cor­po­ra­tion, was per­formed in mul­ti­ple loca­tions, includ­ing the Mayo Clinic, USCF, and San Fran­cisco Vet­eran Affairs Med­ical Center.

Alvaro Fer­nan­dez: Dr. Zelin­ski. Thank you for being with us. Could you start by set­ting the con­text and pro­vid­ing an overview of how human cog­ni­tive abil­i­ties typ­i­cally evolve as we age based on insights from your Long Beach Lon­gi­tu­di­nal Study?

Eliz­a­beth Zelin­ski: Of course. The first con­cept to under­stand is that dif­fer­ent cog­ni­tive skills evolve over the lifes­pan in dif­fer­ent ways. Some that rely on expe­ri­ence, such as vocab­u­lary, actu­ally improve as we age. Some tend to decline grad­u­ally, start­ing in our late 20s. This hap­pens, for exam­ple, with pro­cess­ing speed (how long it takes us to process and respond to infor­ma­tion), mem­ory, and rea­son­ing. We could sum­ma­rize this phe­nom­e­non by say­ing that as we age we get bet­ter at deal­ing with the famil­iar, but worse at deal­ing with the new. We can always learn, but at a slower pace.

Are there any spe­cific tip­ping or inflec­tion points in this trend, any age when the rate of decline is more pronounced?

We don’t have a clear answer to that. It depends a lot on the indi­vid­ual. In gen­eral it is a grad­ual, cumu­la­tive process, so that by age 70 we sta­tis­ti­cally see clear age declines. Which, for exam­ple, is a strong fac­tor deter­min­ing why older adults strug­gle to adapt to new tech­nolo­gies, but why try­ing to learn them pro­vides needed men­tal stim­u­la­tion. Now we know that genes only account for a por­tion of this decline. Much of it depends on our envi­ron­ment, lifestyle and actions.

Can you sum­ma­rize what a healthy indi­vid­ual can do to slow down this process of decline, and help stay healthy and pro­duc­tive as long as possible?

One gen­eral rec­om­men­da­tion is to do every­thing we can to pre­vent or delay dis­ease processes, such as dia­betes or high-blood pres­sure, that have a neg­a­tive effect on our brains. For exam­ple, it is a tragedy in our soci­ety that we usu­ally reduce our lev­els of phys­i­cal exer­cise dras­ti­cally after we leave school.

Let me then ask: what are the rel­a­tive virtues of phys­i­cal vs. men­tal exercise?

Great ques­tion! That in fact leads into my sec­ond rec­om­men­da­tion. Aer­o­bic exer­cise has been shown to Read the rest of this entry »

Today I have an announce­ment to make. You prob­a­bly are seeing all the arti­cles about Brain Fit­ness in the press and wondering, “What is this all about?”, “Can some­one help me nav­i­gate through all the pro­grams out there?”, “How is Brain Fit­ness rel­e­vant to me in my per­sonal life or at work?”. Well…we are deliv­er­ing a series of work­shops to com­pa­nies and orga­ni­za­tions com­bin­ing mod­ules –includ­ing sci­en­tific overview, the indus­try trends and key play­ers, fun team-building exer­cises– that can be tai­lored to each organization’s spe­cific needs. Ses­sions last from 1 to 6 hours, depend­ing on the group’s com­po­si­tion and agenda and are deliv­ered either in per­son or via web conference.

We want to be able to reach more orga­ni­za­tions, so please let us know of any ideas!

Some recent examples

1. Man­ag­ing Stress for Peak Per­for­mance (we men­tioned some notes on an Accen­ture ses­sion)

New and chal­leng­ing sit­u­a­tions – such as tak­ing on new respon­si­bil­i­ties– can trig­ger reac­tions in our brain and body that limit or even block our decision-making abil­i­ties. These reac­tions may also harm our long-term brain power and health. Although we can­not avoid change and stress­ful sit­u­a­tions, we can learn how to man­age our stress lev­els to ensure peak performance-even in tough moments. The lat­est neu­ro­science research proves that stress man­age­ment is a train­able “men­tal mus­cle.” This is true for any high pres­sure pro­fes­sion, be it trad­ing, sports, or sim­ply mod­ern life.

2. The Sci­ence of Brain Health and Brain Fit­ness (sim­i­lar to what I will teach at UC Berke­ley OLLI)

Neu­ro­sci­en­tists have shown how the human brain retains neu­ro­plas­tic­ity (the abil­ity to rewire itself) and neu­ro­ge­n­e­sis (the cre­ation of new neu­rons) dur­ing its full life­time, lead­ing to a new under­stand­ing of Read the rest of this entry »

Q: How can I improve my mem­ory? Is there a daily exer­cise I can do to improve it?

A: The most impor­tant com­po­nent of mem­ory is atten­tion. By choos­ing to attend to some­thing and focus on it, you cre­ate a per­sonal inter­ac­tion with it, which gives it per­sonal mean­ing, mak­ing it eas­ier to remem­ber.
