1) Bay­crest cre­ates Cen­tre for Brain Fit­ness with $10-million Invest­ment from Ontario Gov­ern­ment (Canada NewsWire)

- “Today the Ontario Gov­ern­ment took a large step in this direc­tion by
announc­ing it is invest­ing $10 mil­lion dol­lars to cre­ate the Cen­tre for Brain
Fit­ness at Baycrest.”

- “Bay­crest will part­ner with the Toronto-based MaRS Ven­ture Group to
develop and mar­ket scientifically-proven prod­ucts for the clinic, work­place
and home envi­ron­ments.“
– “Prod­ucts in devel­op­ment over the next 10 years will include cog­ni­tive
assess­ment soft­ware (in a portable com­puter tablet) that allows clin­i­cians to
mea­sure in a sim­ple and rapid man­ner mem­ory and pro­cess­ing in peo­ple who have had a stroke, may have Alzheimer’s or other mem­ory chal­lenges; brain fit­ness
prod­ucts to help healthy aging adults (ages 45–75) main­tain their cog­ni­tive
func­tions, plus an addi­tional prod­uct suite for care­givers to pro­vide
cog­ni­tive reha­bil­i­ta­tion to peo­ple with mild cog­ni­tive impair­ment and demen­tia
who live in long-term care facil­i­ties and retire­ment homes; exec­u­tive train­ing
pro­gram for cor­po­ra­tions wish­ing to help their aging employ­ees improve
cog­ni­tive func­tions to remain pro­duc­tive; and an internet-based out­reach
pro­gram to sup­port peo­ple car­ing for loved ones with mild to medium cog­ni­tive
impair­ment.“
Com­ments: Fas­ci­nat­ing. And very well timed.

 

2) Cog­ni­tive tests are the best way to select med­ical stu­dents (EurekAlert)

- “Cog­ni­tive abil­ity tests are the best way for med­ical schools to select their entrants, rather than inter­views and psy­cho­log­i­cal tests, says an edi­to­r­ial in this week’s BMJ. (Note: British Med­ical Journal)”

- “Accord­ing to the authors, doc­tors should have three broad attributes—cognitive abil­ity, human­ity, and dili­gence. While it would be desir­able to screen poten­tial doc­tors for all these attrib­utes, the evi­dence sug­gests that only cog­ni­tive abil­ity can be assessed with rea­son­able accu­racy in the con­text of mass selection.”

- “The authors there­fore sug­gest that tests of cog­ni­tive abil­ity are the best way to select med­ical stu­dents because the processes they test are sim­i­lar to those used in clin­i­cal practice—the appli­ca­tion of knowl­edge to a problem.’

Com­ment: what spe­cific mix of cog­ni­tive abil­i­ties are we talk­ing about? for what spe­cific jobs? there is no sin­gle over­ar­ch­ing “cog­ni­tive abil­ity”. Hav­ing said that, the con­cept is appealling.

3) High blood pres­sure hard on the aging brain (Reuters)

- “Opti­mal con­trol of blood pres­sure may be ben­e­fi­cial in atten­u­at­ing the risk of cog­ni­tive decline as the pop­u­la­tion ages,” they conclude.

Com­ment: the study talks about “asso­ci­a­tions”. Now, which is the egg and which the chicken? can it be that per­sons suf­fer­ing cog­ni­tive decline on, for exam­ple, self-regulation or exec­u­tive skills, can’t man­age their diet and lifestyle as well thereby con­tribut­ing to blood pres­sure problems?

4) Alzheimer’s tests ben­e­fi­cial for seniors (Atlanta-Journal Constitutional)

- “Solomon, clin­i­cal direc­tor of the Mem­ory Clinic in Burling­ton, Vt. “But senil­ity and cog­ni­tive deficits are not typ­i­cal of the aging process. They sig­nal a dis­ease process.”

- “Doc­tors argue that older peo­ple need to think of the func­tion of their mind as they would the con­di­tion of their heart or the sta­bil­ity of their blood pressure”

Com­ment: couldn’t agree more with these state­ments. We pre­dict we will start to see main­stream, good, inex­pen­sive base­line ass­es­ments of cog­ni­tive func­tion (not clin­i­cal diagnosis) in a few years.

5) Dementia-Dreading Baby Boomers Spur Race to Invent Brain Games (Bloomberg)

- “Insur­ance com­pa­nies includ­ing Humana Inc., the sec­ond– largest seller of Medicare drug plans, are encour­ag­ing pol­i­cy­hold­ers to use the games. Treat­ing Alzheimer’s and demen­tia patients in 2005 cost the U.S. government’s Medicare and Med­ic­aid health pro­grams $112 bil­lion, a total that will reach $184 bil­lion by 2015, accord­ing to the Alzheimer’s Association.”

- “In Merzenich’s view, the only way to rein­vig­o­rate the brain is through con­tin­ued learn­ing. That stim­u­lates neu­rons, the nerve cells that carry mes­sages in the brain, to fire and form new branches. Solv­ing cross­word puz­zles or play­ing bridge keeps the mind active but doesn’t make it per­form new tasks, he says.”

Com­ment: I am quoted sev­eral times in the arti­cle, which is over­all pretty good. But the reporter and I did talk about many other areas not mentioned-I do find it fas­ci­nat­ing to observe that, whereas the research for cog­ni­tive train­ing is much more solid in other areas, healthy aging and dementia is get­ting all the media atten­tion now.

6) Viv­ity Labs launches Fit Brains brain-training game site (VentureBeat) 

- “We call it guilt-free gam­ing,” said Cole, whose com­pany (Note: Fit­Brains) recently raised $1 mil­lion in fund­ing from undis­closed angels. “We’ll go after the casual games audi­ence that wants to keep their minds sharp.”

Com­ment: how will the increas­ing num­ber of “brain train­ing” web­sites dif­fer­en­ti­ate themselves?

7) Depres­sion and Alzheimer’s (NHS Choices)

- “This study chal­lenges the the­ory that depres­sion and demen­tia are caused by another fac­tor. It there­fore adds weight to, but does not prove, the the­ory that depres­sion is a risk fac­tor for demen­tia. How­ever, this study has short­com­ings, and fur­ther research that is free of these should pro­vide a clearer pic­ture. Until more is known, depres­sion suf­fer­ers should not be overly wor­ried that they will develop dementia.”

Com­ment: I guess that last sen­tence offers good news…
