The role of vit­a­min D in the brain appeared evi­dent in the 1980s when researchers found key pro­teins in the brain involved in vit­a­min D metab­o­lism. A lot of clin­i­cal evi­dence has accu­mu­lated since then sug­gest­ing that low vit­a­min D lev­els may poten­tially result in cog­ni­tive decline. Nonethe­less the results are mixed and not all pre­vi­ous stud­ies have show that low lev­els of vit­a­min D are indeed asso­ci­ated with cog­ni­tive decline or dementia.

A 2010 study eval­u­ated this ques­tion for the first time by fol­low­ing the same indi­vid­u­als over the years, instead of com­par­ing peo­ple with nor­mal lev­els and peo­ple with low-levels of vit­a­min D. This study fol­lowed 858 adults 65 years and older over 6-years. Results showed an increased risk of cog­ni­tive decline in patients with vit­a­min D defi­ciency. Read the rest of this entry »

Every­one these days is talk­ing about edu­ca­tion and test­ing reform, but why is rel­e­vant brain research often ignored? Which organ if not the brain does the learn­ing and teach­ing part? Renowned edu­ca­tor and brain expert Dr. Robert Syl­wester shares his rec­om­mended Top Brain Books for Edu­ca­tors and Learn­ers to help inform the con­ver­sa­tion. A must read!

Save the Date: the 2011 Sharp­Brains Sum­mit, the sec­ond edi­tion of our annual indus­try and research con­fer­ence, will take place vir­tu­ally from March 28th to March 31st 2010. Details will fol­low soon.

Research Bites

Foot­ball and brain dam­age: In high-contact sports such as foot­ball, even hits not lead­ing to con­cus­sions can affect the brain.

How to take omega-3: Eat­ing fish (source of omega-3) reduces risks of demen­tia but DHA sup­ple­ments have no effect on Alzheimer’s symptoms.

Vit­a­mins against Alzheimer’s? A good review shows that Vit­a­min B has unclear effects on mem­ory and cog­ni­tive decline.

Brain train­ing helps older dri­vers: tar­geted cog­ni­tive train­ing can help reduce older dri­vers’ car crashes. Dr. Mich­e­lon explains why and how.

An inter­est­ing and very well-documented arti­cle in the Los Ange­les Times reviews stud­ies look­ing at Vit­a­min B and its role in improv­ing mem­ory.

The vit­a­mins — includ­ing folic acid and vit­a­mins B6 and B12 — are often touted as a way to improve mem­ory and stave off cog­ni­tive decline. The claims are based on the find­ing that lev­els of the vit­a­min are low in peo­ple with var­i­ous forms of cog­ni­tive impair­ment Read the rest of this entry »

Our fel­low blog­ger Jeremy over at Psy­Blog has writ­ten a thought­ful post com­par­ing the value of a num­ber of cog­ni­tive enhanc­ing tools. His over­all verdict?

“The evi­dence for exer­cise boost­ing cog­ni­tive func­tion is head-and-shoulders above that for brain train­ing, drugs, nutri­tional sup­ple­ments and med­i­ta­tion. Sci­en­tif­i­cally, on the cur­rent evi­dence, exer­cise is the best way to enhance your cog­ni­tive func­tion. And as for its side-effects: yes there is the chance of an injury but exer­cise can also reduce weight, lower the chance of demen­tia, improve mood and lead to a longer life-span. Damn those side-effects!”

Arti­cle: Which Cog­ni­tive Enhancers Really Work: Brain Train­ing, Drugs, Vit­a­mins, Med­i­ta­tion or Exercise?

Jeremy, I started writ­ing this as a com­ment to your post in your blog, but then it got too long. Let me write my reac­tion to your post here.

While I appre­ci­ate your analy­sis and share most of your points, I think the “rank­ing” effort (this type of inter­ven­tion is bet­ter than that one) is ulti­mately mis­lead­ing.  It is based on a faulty search for a gen­eral solution/ magic pill for every­one and everything.

If only things were so sim­ple. Per­haps one day there will be research to sup­port that view, but cer­tainly not today. A num­ber of inter­ven­tions have shown their value. In dif­fer­ent pop­u­la­tions, and con­texts. For “exer­cise is the best way to enhance your cog­ni­tive func­tion” to be true, one needs to have a pretty spe­cific under­stand­ing of “best”, “your” and “cog­ni­tive function”.
