Complex occupations help protect our brains from aging-related cognitive decline

Cog­ni­tive aging: Work helps our brain (AAAS):

A recent study shows that work plays an active role in keep­ing our brains healthy. “We have demon­strat­ed the role of work­ing activ­i­ty on cog­ni­tive per­for­mance”. Pro­fes­sor Raf­fael­la Rumiati says … “Many stud­ies have been focused on the fac­tors influ­enc­ing our brain aging and dif­fer­ences in cog­ni­tive decline have been often observed in asso­ci­a­tion with edu­ca­tion or oth­er relat­ed to qual­i­ty of life. From our analy­sis it emerges that the type of work activ­i­ty also con­tributes to the dif­fer­ences in nor­mal and patho­log­i­cal cog­ni­tive aging”.

Study in China finds that retirement may accelerate cognitive decline, even for those with stable income

by

Peo­ple who retire ear­ly suf­fer from accel­er­at­ed cog­ni­tive decline and may even encounter ear­ly onset of demen­tia, accord­ing to a new eco­nom­ic study (Note: opens PDF) I con­duct­ed with my doc­tor­al stu­dent Alan Adelman.

To estab­lish that find­ing, we exam­ined the effects of a rur­al pen­sion pro­gram Chi­na intro­duced in 2009 that pro­vid­ed peo­ple who par­tic­i­pat­ed with a sta­ble income if they stopped work­ing after the offi­cial retire­ment age of 60. We found that peo­ple who par­tic­i­pat­ed in the pro­gram and retired with­in one or two years expe­ri­enced a cog­ni­tive decline equiv­a­lent to a drop in gen­er­al intel­li­gence of 1.7% rel­a­tive to the gen­er­al pop­u­la­tion. This drop is equiv­a­lent to about three IQ points and could make it hard­er for some­one to adhere to a med­ica­tion sched­ule or con­duct finan­cial plan­ning. The largest neg­a­tive effect was in what is called “delayed recall,” which mea­sures a person’s abil­i­ty to remem­ber some­thing men­tioned sev­er­al min­utes ago. Neu­ro­log­i­cal research links prob­lems in this area to an ear­ly onset of demen­tia.

On centenarians, memory, Mars, tDCS, ADHD, digital health, beautiful brains, and more

Hen­drik­je van Andel Schip­per (1890–2005)

Wel­come to a new edi­tion of Sharp­Brains’ e‑newsletter, fea­tur­ing ten time­ly resources and research find­ings for life­long brain and men­tal fitness.

#1. Let’s start with a fas­ci­nat­ing sto­ry and study 🙂

Study with 330 cen­te­nar­i­ans finds that cog­ni­tive decline is not inevitable … (Henne Hol­stege, PhD, assis­tant pro­fes­sor at Ams­ter­dam Uni­ver­si­ty Med­ical Cen­ter) said her inter­est in research­ing aging and cog­ni­tive health was inspired by the “fas­ci­nat­ing” sto­ry of Hen­drik­je van Andel Schip­per, who died at age 115 in 2005 “com­plete­ly cog­ni­tive­ly healthy.”

#2. Neu­ro­sci­en­tist Lisa Gen­o­va, author of the beau­ti­ful nov­el Still Alice, releas­es non-fic­tion book on Mem­o­ry: “It is sober­ing to real­ize that three out of four pris­on­ers who are lat­er exon­er­at­ed through DNA evi­dence were ini­tial­ly con­vict­ed on the basis of eye­wit­ness tes­ti­mo­ny. “You can be 100 per­cent con­fi­dent in your vivid mem­o­ry,” Gen­o­va writes, “and still be 100 per­cent wrong” … Gen­o­va assures her read­ers that only two per cent of Alzheimer’s cas­es are of the strict­ly inher­it­ed, ear­ly-onset kind. For most of us, our chances of devel­op­ing the dis­ease are high­ly amenable to interventions…”

#3. Time­ly tips for the week­end: Shape your envi­ron­ment, shape your mind

  • Sur­round your­self with nature
  • Cre­ate oppor­tu­ni­ties for awe
  • Clear the clutter

#4. “For a mis­sion to suc­ceed, high men­tal and cog­ni­tive func­tion would be absolute­ly crit­i­cal; astro­nauts would be called on to per­form demand­ing tasks in a demand­ing envi­ron­ment. Los­ing 20 IQ points halfway to Mars is not an option … Stress—an emo­tion­al or men­tal state result­ing from tense or over­whelm­ing circumstances—and the body’s response to it, which involves mul­ti­ple sys­tems, from metab­o­lism to mus­cles to memory—may be the chief chal­lenge that astro­nauts face.” Next in NASA’s path to Mars: Over­com­ing astro­nauts’ cog­ni­tive and men­tal health challenges

#5. Study: Depres­sion affects visu­al per­cep­tion … mak­ing it more accu­rate (based on a cool opti­cal illusion)

#6. It’s good to have more tools in the neu­ro toolkit…assuming we use them wise­ly: Emerg­ing appli­ca­tions of tran­scra­nial Direct Cur­rent Stim­u­la­tion (tDCS): e‑sports skills train­ing, cog­ni­tive enhance­ment in old­er adults

#7. Does ADHD treat­ment enable long-term aca­d­e­m­ic suc­cess? (Yes, espe­cial­ly when phar­ma­co­log­i­cal and non-phar­ma treat­ments are combined)

#8. Men­tal Health in the Dig­i­tal Age: From dig­i­tal ther­a­peu­tics to per­son­al­ized men­tal health solu­tions: Pear Ther­a­peu­tics expands plat­form via part­ner­ships with Empat­i­ca, etec­tRx, Key­Wise, and Winterlight

#9. The award was won last year by Indi­an vil­lage teacher Ran­jitsinh Disale; who will be next? Final day to nom­i­nate teach­ers for the $1M Glob­al Teacher Prize 2021

#10. And last, but cer­tain­ly not least, let’s wel­come Men­tal Health Month (May) by appre­ci­at­ing our beau­ti­ful brains

Wish­ing you a men­tal­ly healthy and cog­ni­tive­ly stim­u­lat­ing month of May,

Study with 330 centenarians finds that cognitive decline is not inevitable

Hen­drik­je van Andel Schip­per (1890–2005)

Age-Relat­ed Cog­ni­tive Decline May Not Be Inevitable (Web­MD):

It is often assumed that a decrease in mem­o­ry and brain func­tion are inevitable parts of aging, but a new study of cen­te­nar­i­ans sug­gests otherwise.

Inves­ti­ga­tors found that despite the pres­ence of neu­ro­log­i­cal issues gen­er­al­ly asso­ci­at­ed with Alzheimer’s dis­ease (AD), many cen­te­nar­i­ans main­tained high lev­els of cog­ni­tive performance.

(Henne Hol­stege, PhD, assis­tant pro­fes­sor at Ams­ter­dam Uni­ver­si­ty Med­ical Cen­ter) said her inter­est in research­ing aging and cog­ni­tive health was inspired by the “fas­ci­nat­ing” sto­ry of Hen­drik­je van Andel Schip­per, who died at age 115 in 2005 “com­plete­ly cog­ni­tive­ly healthy.” Her moth­er, who died at age 100, was also cog­ni­tive­ly intact at the end of her life.

Buyer beware: The story of a pricey and “credentialled” program to end Alzheimer’s Disease

by

When her hus­band was diag­nosed with ear­ly-stage Alzheimer’s dis­ease in 2015, Eliz­a­beth Pan was dev­as­tat­ed by the lack of options to slow his inevitable decline. But she was encour­aged when she dis­cov­ered the work of a UCLA neu­rol­o­gist, Dr. Dale Bre­desen, who offered a com­pre­hen­sive lifestyle man­age­ment pro­gram to halt or even reverse cog­ni­tive decline in patients like her husband.

Given cognitive strengths and needs are diverse, what brain training may work best for each person and under which conditions?

Does ‘Brain Train­ing’ Actu­al­ly Work? (Sci­en­tif­ic American):

If there were an app on your phone that could improve your mem­o­ry, would you try it? Who wouldn’t want a bet­ter mem­o­ry? After all, our rec­ol­lec­tions are frag­ile and can be impaired by dis­eases, injuries, men­tal health con­di­tions and, most acute­ly for all of us, aging.
