Vitamin B against Alzheimer’s? Too early to tell.

November 9, 2010 by Dr. Pascale Michelon

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 more…] about Vit­a­min B against Alzheimer’s?

Cognitive stimulation is beneficial, even after diagnosis of Alzheimer’s

October 20, 2010 by Dr. Pascale Michelon

An inter­est­ing arti­cle in Nature Reviews last month reviewed sev­er­al stud­ies show­ing that cog­ni­tive inter­ven­tion can be ben­e­fi­cial even for indi­vid­u­als already diag­nosed with Alzheimer’s Dis­ease (Buschert et al., 2010).

The arti­cle shows that patients with mild-to-mod­er­ate demen­tia can ben­e­fit from a range of cog­ni­tive inter­ven­tions: from train­ing of par­tial­ly spared cog­ni­tive func­tions to train­ing on activ­i­ties of dai­ly liv­ing. Results sug­gest that such inter­ven­tions can improve glob­al cog­ni­tion, abil­i­ties of dai­ly liv­ing and qual­i­ty of life in these patients.

Patients with mod­er­ate-to-severe demen­tia seem to ben­e­fit from gen­er­al engage­ment in activ­i­ties that enhance cog­ni­tive and social func­tion­ing in a non-spe­cif­ic manner.

In gen­er­al, for patients diag­nosed with Alzheimer’s Dis­ease, the reviewed stud­ies sug­gest that pro­grams focus­ing on glob­al cog­ni­tive stim­u­la­tion are more effec­tive than pro­grams that train spe­cif­ic cog­ni­tive functions.

The oppo­site seems true for peo­ple diag­nosed with Mild Cog­ni­tive Impair­ment (MCI). As you may remem­ber, MCI diag­no­sis is made upon objec­tive mem­o­ry deficits that do not inter­fere with activ­i­ties of dai­ly liv­ing. 5 to 10% of peo­ple with MCI devel­op demen­tia with­in 1 year after being diagnosed.

It is inter­est­ing to see that the type of cog­ni­tive inter­ven­tion one may ben­e­fit from changes over the years, depend­ing on one’s cog­ni­tive sta­tus. This shows once again that there is no gen­er­al mag­ic pill in terms of brain fit­ness: Some inter­ven­tions or pro­grams work because they meet the needs of some spe­cif­ic indi­vid­u­als. No pro­gram can work for everybody.

Dr. Art Kramer on Why We Need Walking Book Clubs to Enhance Cognitive Fitness and Brain Health

June 25, 2008 by Alvaro Fernandez

Art KramerDr. Arthur Kramer is a Pro­fes­sor in the Uni­ver­si­ty of Illi­nois Depart­ment of Psy­chol­o­gy, the Cam­pus Neu­ro­science Pro­gram, the Beck­man Insti­tute, and the Direc­tor of the Bio­med­ical Imag­ing Cen­ter at the Uni­ver­si­ty of Illinois.

I am hon­ored to inter­view him today.

Dr. Kramer, thank you for your time. Let’ start by try­ing to clar­i­fy some exist­ing mis­con­cep­tions and con­tro­ver­sies. Based on what we know today, and your recent Nature piece (ref­er­enced below), what are the 2–3 key lifestyle habits would you sug­gest to a per­son who wants to delay Alzheimer’s symp­toms and improve over­all brain health?

First, Be Active. Do phys­i­cal exer­cise. Aer­o­bic exer­cise, 30 to 60 min­utes per day 3 days per week, has been shown to have an impact in a vari­ety of exper­i­ments. And you don’t need to do some­thing stren­u­ous: even walk­ing has shown that effect. There are many open ques­tions in terms of spe­cif­ic types of exer­cise, dura­tion, mag­ni­tude of effect but, as we wrote in our recent Nature Reviews Neu­ro­science arti­cle, there is lit­tle doubt that lead­ing a seden­tary life is bad for our cog­ni­tive health. Car­dio­vas­cu­lar exer­cise seems to have a pos­i­tive effect.

Sec­ond, Main­tain Life­long Intel­lec­tu­al Engage­ment. There is abun­dant prospec­tive obser­va­tion­al research show­ing that doing more men­tal­ly stim­u­lat­ing activ­i­ties reduces the risk of devel­op­ing Alzheimer’s symptoms.

Let me add, giv­en all media hype, that no “brain game” in par­tic­u­lar has been shown to have a long-term impact on Alzheimer’s or the main­te­nance of cog­ni­tion across extend­ed peri­ods of time. It is too ear­ly for that-and con­sumers should be aware of that fact. It is true that some com­pa­nies are being more sci­ence-based than oth­ers but, in my view, the con­sumer-ori­ent­ed field is grow­ing faster than the research is.

Ide­al­ly, com­bine both phys­i­cal and men­tal stim­u­la­tion along with social inter­ac­tions. Why not take a good walk with friends to dis­cuss a book? We lead very busy lives, so the more inte­grat­ed and inter­est­ing activ­i­ties are, the more like­ly we will do them.
