In the past few days you may have come across head­lines claim­ing that weight loss can improve mem­ory. If so, you may be won­der­ing what to make of this.

Let’s take a brief look at the study at the ori­gin of these arti­cles. Par­tic­i­pants were 109 bariatric surgery patients and 41 obese peo­ple (con­trols) who had not under­gone surgery. Bariatric surgery refers mostly to gas­tric bypass surgery, which cre­ates a smaller stom­ach and bypasses part of the small intes­tine. The bariatric patients were enrolled in the Lon­gi­tu­di­nal Assess­ment of Bariatric Surgery project con­ducted, among oth­ers, by researchers at Kent State uni­ver­sity and Colum­bia University.

The mem­ory of the 150 par­tic­i­pants was assessed before the surgery as well as 12 weeks after. Results showed that the mem­ory of the surgery patients had improved whereas the mem­ory of the obese con­trols had declined. Read the rest of this entry »

A few weeks ago I had the plea­sure to give a talk to one hun­dred or so staff mem­bers at New York Pub­lic Library. As you would expect, it was a very stim­u­lat­ing group, and one of the par­tic­i­pants, Brigid Caha­lan, just wrote a fun blog post on her impres­sions from the event:

Brain Fit­ness at New York Pub­lic Library:

- “After attend­ing a recent staff train­ing ses­sion offered by the library’s Office of Staff Devel­op­ment, I decided to return to a habit of my childhood–eating sar­dines.“
– key pil­lars for brain health …are… “1) A bal­anced diet; 2) Car­dio­vas­cu­lar phys­i­cal exer­cise; 3) Stress man­age­ment; and 4) Brain exer­cise: Nov­elty, Vari­ety, Chal­lenge (as long as it doesn’t stress us out).”

Com­ment: A very inter­est­ing trend of observe — the grow­ing role of pub­lic libraries in pro­vid­ing qual­ity brain health infor­ma­tion and even, why not, becom­ing community-based brain fit­ness des­ti­na­tions. After all, is it not men­tal stim­u­la­tion of all sorts, incor­po­rat­ing Nov­elty, Vari­ety, and Chal­lenge, what they truly offer?

Last week, the US Car Care Coun­cil released a list of tips on how to take care of your car and “save big money at the pump in 2008.”

You may not have paid much atten­tion to this announce­ment. Yes, it’s impor­tant to save gas these days; but, it’s not big news that good main­te­nance habits will improve the per­for­mance of a car, and extend its life.

If we can all agree on the impor­tance of main­tain­ing our cars that get us around town, what about main­tain­ing our brains sit­ting behind the wheel?

A spate of recent news cov­er­age on brain fit­ness and “brain train­ing” has missed an impor­tant con­stituency: younger peo­ple. Recent advance­ments in brain sci­ence have as tremen­dous impli­ca­tions for teenagers and adults of all ages as they do for seniors.

In a recent con­ver­sa­tion with neu­ro­sci­en­tist Yaakov Stern of Colum­bia Uni­ver­sity, he related how sur­prised he was when, years ago, a reporter from Sev­en­teen mag­a­zine requested an inter­view. The reporter told Dr. Stern that he wanted to write an arti­cle to moti­vate kids to stay in school and not to drop out, in order to start build­ing their Cog­ni­tive Reserve early and age more gracefully.

Fun arti­cle in the San Fran­cisco Exam­iner today on how High-tech ‘brain gyms’ tone minds, reduce stress. Quotes:

• “Sharp­Brains and Posit Sci­ence are just two of a grow­ing num­ber of start-up com­pa­nies lead­ing the way in the area of pack­ag­ing and devel­op­ing suites of soft­ware they call “brain gyms.”
• “Sharp­Brains offers a suite of prod­ucts that eval­u­ate buy­ers’ needs and tar­get their weak­ness, gen­tly push­ing for improve­ment, Fer­nan­dez said. One pro­gram helps improve mem­ory using a num­ber game (here); another pro­vides instant biofeed­back to users so they can prac­tice breath­ing and pos­i­tive think­ing to reduce stress (here), Fer­nan­dez said.”
• “I can start see­ing the changes in my stress level take place right in front of my eyes,” said Baba Shiv (pro­file here), a neu­ro­sci­en­tist and pro­fes­sor at Stanford’s Grad­u­ate School of Busi­ness, who uses Freeze-Framer 2.0 (here), one of the pro­grams licensed by Sharp­Brains. By mon­i­tor­ing his stress level through heart mon­i­tors hooked to his per­sonal com­puter at work, he dis­cov­ered that con­stantly mon­i­tor­ing his e-mail inbox raised his stress level, Shiv said. Now he lim­its him­self to check­ing e-mail every two hours, Shiv said.

The reporter did a great job in under­stand­ing and com­mu­ni­cat­ing a new and some­times com­plex topic. Read the arti­cle: High-tech ‘brain gyms’ tone minds, reduce stress.
