When early retirement equals mental retirement and memory decline

The New-York Times reports on the study pub­lished a few days ago in the Jour­nal of Eco­nom­ic Per­spec­tives, “Men­tal retire­ment”:

… Data from the Unit­ed States, Eng­land and 11 oth­er Euro­pean coun­tries sug­gest that the ear­li­er peo­ple retire, the more quick­ly their mem­o­ries decline.

… what aspect of work is doing that, Dr. Suz­man said. “Is it the social engage­ment and inter­ac­tion or the cog­ni­tive com­po­nent of work, or is it the aer­o­bic com­po­nent of work?” he asked. “Or is it the absence of what hap­pens when you retire, which could be increased TV watch­ing?”

Com­ments: This new study is anoth­er piece of evi­dence accu­mu­lat­ing with more and more oth­ers sug­gest­ing that a brain healthy life-style requires con­stant cog­ni­tive chal­lenge to help main­tain high-lev­el cog­ni­tive func­tions. Whether it is speak­ing mul­ti­ple lan­guages, phys­i­cal­ly exer­cis­ing or stay­ing men­tal­ly active, our every­day life can pos­i­tive­ly impact our brain health.  Some­thing to keep in mind after retirement…and to even retire the word “retire­ment”!

The results are also intrigu­ing because work­ing com­bines mul­ti­ple aspects of a brain-healthy lifestyle (social engage­ment, men­tal stim­u­la­tion) with aspects not so good for the brain (stress, absence of phys­i­cal exer­cise in some cas­es). How­ev­er, it seems that, over­all, the good aspects of work­ing take over the bad ones as far as mem­o­ry func­tions are con­cerned.

What is Brain Fitness, anyway?

Vijay, one of our read­ers, wrote yes­ter­day a very thought­ful com­ment :

What is brain fit­ness and how it is mea­sured? Is it the same as mind fit­ness which seeks to achieve bal­ance in life?”

I am curi­ous to learn how you would answer that ques­tion. I will add my per­spec­tive over the week­end, since I don’t want to bias your thoughts now.

What is brain fit­ness and how it is mea­sured?

Lifelong Learning and New Neurons in Adults

Very inter­est­ing new study, Crit­i­cal Peri­od Plas­tic­i­ty of Adult-Born Neu­rons, pub­lished in the jour­nal Neu­ron by a team of Johns Hop­kins Uni­ver­si­ty School of Med­i­cine researchers. The press release New Adult Brain Cells May Be Cen­tral To Life­long Learn­ing con­tains a good sum­ma­ry (the bold for­mat is mine):

  • The steady for­ma­tion of new brain cells in adults may rep­re­sent more than mere­ly a patch­ing up of aging brains, a new study has shown.”
  • The new adult brain cells may serve to give the adult brain the same kind of learn­ing abil­i­ty that young brains have while still allow­ing the exist­ing, mature cir­cuit­ry to main­tain sta­bil­i­ty.”
  • The researchers found that the new adult neu­rons showed a pat­tern of chang­ing plas­tic­i­ty very sim­i­lar to that seen in brain cells in new­born ani­mals. That is, the new adult brain cells showed a “crit­i­cal peri­od” in which they were high­ly plas­tic before they set­tled into the less plas­tic prop­er­ties of mature brain cells. In new­born ani­mals, such a crit­i­cal peri­od enables an impor­tant, ear­ly burst of wiring of new brain cir­cuit­ry with expe­ri­ence.”
  • The researchers also observed in the new adult neu­rons anatom­i­cal evi­dence of the same kind of for­ma­tion of new con­nec­tions that take place in the brains of new­borns as they wire new path­ways in response to expe­ri­ence.”
  • They con­clud­ed that “adult neu­ro­ge­n­e­sis may rep­re­sent not mere­ly a replace­ment mech­a­nism for lost neu­rons, but instead an ongo­ing devel­op­men­tal process that con­tin­u­ous­ly reju­ve­nates the mature ner­vous sys­tem by offer­ing expand­ed capac­i­ty of plas­tic­i­ty in response to expe­ri­ence through­out life.”

In short: not only do we know today that the adult brain is capa­ble of cre­at­ing new neu­rons, but this shows that our expe­ri­ence influ­ences what hap­pens to those neu­rons once cre­at­ed. Pret­ty rev­o­lu­tion­ary under­stand­ing, that still needs to per­me­ate through soci­ety and influ­ence our lifestyles and habits.

GABA Receptor
Steven Edwards at Wired Blog writes a post titled Yoga Boosts Brain’s GABA Lev­els, say­ing that “Par­tic­i­pants in the yoga group had a 27% increase in GABA lev­els, while those in the read­ing group remained unchanged. Co-authors Chris Streeter from BUSM and Domenic Ciraulo point­ed out that this research shows a method of treat­ing low GABA states. Fair­ly obvi­ous — yes — but this shows a non­phar­ma­co­log­i­cal method for increas­ing GABA lev­els that peo­ple can act on now, with­out wait­ing for a drug to go through FDA approval.”

Hav­ing attend­ed last week a con­fer­ence where neu­rophar­ma exec­u­tives pre­sent­ed all their future drugs against obe­si­ty, anx­i­ety, depression…I couldn’t agree more. The rates of seri­ous side effects of these drugs are astound­ing, yet as a soci­ety we seem to pre­fer to rely on tak­ing drugs when are sick rather than proac­tive­ly tak­ing charge of our health and lifestyles and do our best (which not always is enough) to pro­tect our fit­ness and well­ness.
