Obe­sity linked to Cog­ni­tion (Health­Canal):

- “Obese peo­ple tend to per­form worse than healthy peo­ple at cog­ni­tive tasks like plan­ning ahead, a lit­er­a­ture review has found, con­clud­ing that psy­cho­log­i­cal tech­niques used to treat anorex­ics could help obese peo­ple too.” Read the rest of this entry »

Very inter­est­ing new data rein­forc­ing two main themes we have been ana­lyz­ing for a while:
1) We bet­ter start pay­ing seri­ous atten­tion (and R&D dol­lars) to lifestyle-based and non-invasive cog­ni­tive and emo­tional health inter­ven­tions, which are mostly ignored in favor of inva­sive, drug-based options
2) Inter­ven­tions will need to be per­son­al­ized. The study below ana­lyzes data at the coun­try level, but the same logic applies to the indi­vid­ual level

Many fear Alzheimer’s, want to be tested: sur­vey (Reuters):

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 »

With three years still left until pub­li­ca­tion, the fights over the new ver­sion of the psy­chi­atric diag­nos­tic man­ual, the DSM-V, are hot­ting up and The New York Times has a con­cise arti­cle that cov­ers most of the main point of contention.

- “What you have in the end,  Mr. Shorter said, “is this process of sort­ing the deck of symp­toms into syn­dromes, and the out­come all depends on how the cards fall.

- Psy­chi­a­trists involved in prepar­ing the new man­ual con­tend that it is too early to say for sure which cards will be added and which dropped.

Although I doubt the DSM com­mit­tee are using that exact metaphor, it cer­tainly illus­trates the point that the process requires a cer­tain degree of value-judgement.

It’s inter­est­ing, how­ever, that the pub­lic debate is cur­rently focused on whether cer­tain diag­noses should be included or not, rather than whether diag­no­sis itself is use­ful for psychiatry.

We’ve had psy­cho­met­rics for a good 100 years that allow us to mea­sure dimen­sions of human expe­ri­ence and per­for­mance with a much greater degree of accu­racy than Read the rest of this entry »

Play­ing the Blame Game
– Video games stand accused of caus­ing obe­sity, vio­lence, and lousy grades. But new research paints a sur­pris­ingly com­pli­cated and pos­i­tive pic­ture, reports Greater Good Mag­a­zine’s Jeremy Adam Smith.

Cheryl Olson had seen her teenage son play video games. But like many par­ents, she didn’t know much about them.

Then in 2004 the U.S. Depart­ment of Jus­tice asked Olson and her hus­band, Lawrence Kut­ner, to run a fed­er­ally funded study of how video games affect adolescents.

Olson and Kut­ner are the co-founders and direc­tors of the Har­vard Med­ical School’s Cen­ter for Men­tal Health and Media. Olson, a pub­lic health researcher, had stud­ied the effects of media on behav­ior but had never exam­ined video games, either in her research or in her per­sonal life.

And so the first thing she did was watch over the shoul­der of her son, Michael, as he played his video games. Then, two years into her research—which com­bined sur­veys and focus groups of junior high school students—Michael urged her to pick up a joy­stick. “I def­i­nitely felt they should be famil­iar with the games if they were doing the research,” says Michael, who was 16 at the time and is now 18.

Olson started with the PC game Read the rest of this entry »

——————-
1) There were a few inter­est­ing research papers pre­sented at the last  Amer­i­can Psy­cho­log­i­cal Asso­ci­a­tion con­ven­tions around the theme:

Play­ing Video Games Offers Learn­ing Across Life Span, Say Stud­ies
–Skills Trans­fer to Class­room, Sur­gi­cal Pro­ce­dures, Sci­en­tific Think­ing (press release).

Prob­a­bly the most inter­est­ing study was that of 303 laparo­scopic sur­geons, which “showed that sur­geons who played video games requir­ing spa­tial skills and hand dex­ter­ity and then per­formed a drill test­ing these skills were sig­nif­i­cantly faster at Read the rest of this entry »

The arti­cle Clumsy kids more likely to become obese adults: study (CBC)…

- “The study was based on tests of about 11,000 peo­ple in Britain who were tested for hand con­trol, co-ordination and clum­si­ness at age seven and 11, and were then fol­lowed until age 33.”

- “Prof. Scott Mont­gomery of the Karolin­ska Insti­tutet in Stock­holm and his col­leagues at Impe­r­ial Col­lege Lon­don in Eng­land said they pur­posely chose mea­sure­ments of fine hand con­trol such as pick­ing up matches, rather than those likely to be influ­enced by par­tic­i­pat­ing in sports, such as catch­ing balls.”

- “While it is often assumed that the cog­ni­tive impair­ments seen in adult obe­sity are a con­se­quence of excess weight, that could be putting the chicken before the egg, the researchers say”

…reminds me of Judith Beck’s words on how to “Train Your Brain to Think Like a Thin Person”

- “The main mes­sage of cog­ni­tive ther­apy over­all, and its appli­ca­tion in the diet world, is straight-forward: prob­lems los­ing weight are not one’s fault. Prob­lems sim­ply reflect lack of skills–skills that can be acquired and mas­tered through prac­tice. Read the rest of this entry »
