Today’s kids are into multi-tasking. This is the gen­er­a­tion hooked on iPods, IM’ing, video games — not to men­tion TV! Many peo­ple in my gen­er­a­tion think it is won­der­ful that kids can do all these things simul­ta­ne­ously and are impressed with their competence.

Well, as a teacher of such kids when they reach col­lege, I am not impressed. Col­lege stu­dents these days have short atten­tion spans and have trou­ble con­cen­trat­ing. They got this way in sec­ondary school. I see this in the middle-school out­reach pro­gram I help run. At this age kids are really wrapped up in multi-tasking at the expense of focus.

Accord­ing to a Kaiser Fam­ily Foun­da­tion study last year, school kids in all grades beyond the sec­ond grade com­mit­ted, on aver­age, more than six hours per day to TV or videos, music, video games, and com­put­ers. Almost one-third reported that “most of the time” they did their home­work while chat­ting on the phone, surf­ing the Web, send­ing instant mes­sages, watch­ing TV, or lis­ten­ing to music.

Kids think that this enter­tain­ment while study­ing helps their learn­ing. It prob­a­bly does make learn­ing less tedious, but it clearly makes learn­ing less effi­cient and less effec­tive. Multi-tasking vio­lates every­thing we know about how mem­ory works. Now we have objec­tive sci­en­tific evi­dence that Read the rest of this entry »

In other words, may some foods be specif­i­cally good for brain function?

For a great in-depth review of the effects of food on the brain you can check out Fer­nando Gomez-Pinilla’s recent arti­cle in Nature Reviews Neu­ro­science (ref­er­ence below). Here is an overview of the state off the research.

Sev­eral com­po­nents of diet seem to have a pos­i­tive effect on brain function.

Omega-3 fatty acids

These acids are nor­mal con­stituents of cell mem­branes and are essen­tial for nor­mal brain func­tion. Omega-3 fatty acids can be found in fish (salmon), kiwi, and wal­nuts. Docosa­hexaenoic acid, or DHA, is the most abun­dant omega-3 fatty acid in cell mem­branes in the brain. The human body pro­duces DHA but not enough. So we are depen­dent on the DHA that we get from what we eat.

A ran­dom­ized double-blind con­trolled trial (which means seri­ously con­ducted sci­en­tific study) is cur­rently look­ing at the effect of tak­ing omega-3 fatty acids on children’s per­for­mance at school in Eng­land. Pre­lim­i­nary results (Port­wood, 2006) sug­gest that Read the rest of this entry »

I just read a very inter­est­ing arti­cle in Newsweek: Exec­u­tive Func­tions: The School Skill That May Mat­ter More Than IQ. A few quotes:

- “But recent advances in psy­chol­ogy and brain sci­ence are now sug­gest­ing that a child’s abil­ity to inhibit dis­tract­ing thoughts and stay focused may be a fun­da­men­tal cog­ni­tive skill, one that plays a big part in aca­d­e­mic suc­cess from preschool on. Indeed, this and closely related skills may be more impor­tant than tra­di­tional IQ in pre­dict­ing a child’s school performance.”

- “EF (exec­u­tive func­tions) com­prises not only effort­ful con­trol and cog­ni­tive focus but also work­ing mem­ory and men­tal flex­i­bil­ity the abil­ity to adjust to change, to think out­side the box.”

- “When the teacher holds up a cir­cle they clap, with a tri­an­gle they hop, and so forth. The kids are taught to talk them­selves through the men­tal exer­cise: “OK, now clap.” “Twirl now.” This has been shown to flex and enhance the brain’s abil­ity to switch gears, to sup­press one piece of infor­ma­tion and sub in a new one. It takes dis­ci­pline; it’s the ele­men­tary school equiv­a­lent of say­ing “I really need stop think­ing about next week’s vaca­tion and focus on this report.”

The main points: exec­u­tive func­tions are cru­cial for suc­cess in life, AND they can be trained. I couldn’t agree more with the arti­cle in that cog­ni­tive train­ing should be part of the edu­ca­tion cur­ricu­lum and receive more research dol­lars to deter­mine exactly how to best do so.

I read another very inter­est­ing arti­cle on Alzheimer’s Dis­ease. Which may look like a com­pletely dif­fer­ent topic than the one above…but please bear with me. Read the rest of this entry »

The Aspen Health Forum gath­ered an impres­sive group of around 250 peo­ple to dis­cuss the most press­ing issues in Health and Med­ical Sci­ence (check out the Pro­gram and the Speak­ers bios), on Octo­ber 3-6th. It was the first con­fer­ence, by the way, where I have heard a speaker say: “I resus­ci­tated a woman yesterday”.

Key high­lights and trends:

1– Global health prob­lems require the atten­tion of the sci­en­tific com­mu­nity. Richard Klaus­ner encour­aged the sci­en­tific com­mu­nity to focus on Global Prob­lems: mater­nal mor­tal­ity rates, HIV/ AIDS, nutri­tion, can­cer, clean water.  Bill Frist, for­mer Sen­ate Major­ity Leader, added to that list the increas­ing epi­demic risks of global zootic dis­eases (trans­mit­ted between humans and ani­mals), sup­ported by 2 inter­est­ing data points: at any one moment, there are 500,000 peo­ple fly­ing world­wide; in a year, air­lines trans­port the equiv­a­lent of 2 bil­lion passengers.

2– “Let’s get real…Ideology kills”. Mary Robin­son, for­mer Pres­i­dent of Ire­land, on what it takes to stop HIV/ AIDS: “I am from Ire­land, a Catholic coun­try. And I am Catholic. But I can see how ide­ol­ogy kills..we need more empa­thy with real­ity, and to work with local women in those coun­tries who need things like female con­doms.” She was implic­itly crit­i­ciz­ing the large bud­get devoted to unre­al­is­tic absti­nence pro­grams. This ses­sion included a fas­ci­nat­ing exchange where Bill Frist rose from the audi­ence to defend the role of US aid, explain­ing how 60% of retro­vi­ral drugs in African coun­tries have been funded by the Amer­i­can tax­payer, high­light­ing Pres­i­dent Bush’s courage to make HIV/AIDS a top agenda item in many devel­op­ing coun­tries, and crit­i­ciz­ing other coun­tries for not doing enough. Which made Nobel Prize Lau­re­ate Peter Agre, also in the audi­ence, stand up and encour­age the US to really step up to the plate and devote 1% of the GDP to aid, as a num­ber of Euro­pean coun­tries do, instead of 0.1%.

3– Where is the new “Sput­nik”?: Basic sci­ence is cru­cial for inno­va­tion and for eco­nomic growth, but it is often under­ap­pre­ci­ated. Sci­en­tists are not “nerds”, as some­times they are por­trayed in pop­u­lar cul­ture, but peo­ple with a deep curios­ity and drive to solve a Big prob­lem. Many of the speak­ers had been inspired by the Sput­nik and the Apollo mis­sions to become sci­en­tists, at a time when the pro­fes­sion was con­sid­ered cool. Two Nobel Prize Lau­re­ates (Peter Agre, Michael Bishop), talked about their lives and careers try­ing to demys­tify what it takes to be a sci­en­tist and to win a Nobel Prize. Both are grate­ful to the tax­pay­ers dol­lars that funded their research, and insist we must do a bet­ter job at explain­ing the sci­en­tific process to soci­ety at large. Both are proud of hav­ing attended small lib­eral arts col­leges, and hav­ing evolved from there, fueled by their great curios­ity and unpre­dictable, serendip­i­tous paths, into launch­ing new sci­en­tific and med­ical fields.  Bishop listed a num­ber of times where he made deci­sions that were con­sid­ered “career sui­cide” by men­tors and col­leagues, and men­tioned “I was con­fused” around 15 times in 15 minutes…down to earth and inspiring.

4– We need a true Health Care Cul­ture: Mark Ganz sum­ma­rized it best by explain­ing how his health provider group improved care when they rede­fined them­selves from “we are 7,000 employ­ees” to “we are a 3 mil­lion strong com­mu­nity”, mov­ing from Read the rest of this entry »

Wel­come to the August 19, 2007 edi­tion of med­i­cine 2.0.

Med­i­cine 2.0? Yes, some pio­neers are already mak­ing good use of Web 2.0 tools to improve Med­i­cine in a new, col­lab­o­ra­tive way. This blog car­ni­val seems to me to be, in itself, liv­ing proof.

Let’s see.

You may won­der, what exactly is “Med­i­cine 2.0″? well, Con­struc­tive Med­i­cine takes a stab at it, show­ing how it may be much older than we thought.

You want an exam­ple? see a blog­ger (Berta­lan) chron­i­cle an amaz­ing med­ical sim­u­la­tion in Sec­ond Life.

Some blog­gers pro­vide great overview posts:

• A Beginner’s Guide to Read­ing Med­ical Blogs (Vitum Med­i­ci­nus) pro­vides a fan­tas­tic resource cov­er­ing every­thing you need to know about med­ical blogs and blogs in gen­eral, includ­ing why to sub­scribe to RSS feeds (for How, keep reading).
• Nurs­ing and Web 2.0 (Uni­ver­sal Health) is a thought­ful post on the gap between nurs­ing research and prac­tice and how blog­ging and 2.0 can help.
• Essay on the effect of Web 2.0 on the future of med­ical prac­tice and edu­ca­tion (Med­ical Jour­nal of Aus­tralia), that pro­vides a great overview of med­i­cine 2.0, defin­ing and list­ing blogs, wikis, pod­casts and more.
