Study: A combined cognitive-physical training approach may enhance both mind and body as we age

by

A com­bined cog­ni­tive and fit­ness train­ing helps restore old­er adults’ atten­tion abil­i­ties to young adult lev­els (Psy­Post):

A new study found promis­ing results for a com­bined phys­i­cal fit­ness and cog­ni­tive inter­ven­tion designed to enhance neu­ro­plas­tic­i­ty in old­er adults. Using a motion-cap­ture video game, the inter­ven­tion appeared to reme­di­ate age-relat­ed declines in atten­tion. The find­ings were pub­lished in the jour­nal npj Aging.

Combined tDCS neurostimulation and cognitive training found to improve working memory among older adults–especially those with lower starting capacity

by

Giv­ing mem­o­ry a lift: Can games and brain stim­u­la­tion do it? (Med­ical­New­sTo­day):

A person’s work­ing mem­o­ry may decline with age or if they have demen­tia, Parkinson’s dis­ease, or have had a stroke. When this occurs, the loss can affect their day-to-day qual­i­ty of life, turn­ing even sim­ple tasks into often-demor­al­iz­ing chal­lenges.

UC study finds near-transfer of cognitive training to be necessary (yet not sufficient) for far-transfer, broader benefits

by

Guicheng “Ariel” Tan / UCI Work­ing Mem­o­ry & Plas­tic­i­ty Lab

Who ben­e­fits from brain train­ing, and why? (UCI release):

If you are skilled at play­ing puz­zles on your smart­phone or tablet, what does it say about how fast you learn new puz­zles, or more broad­ly, how well can you focus in school or at work? In the lan­guage of psy­chol­o­gists, does “near trans­fer” pre­dict “far transfer”?

A team of psy­chol­o­gists from the Uni­ver­si­ty of Cal­i­for­nia, Irvine and the Uni­ver­si­ty of Cal­i­for­nia, River­side reports in Nature Human Behav­ior that peo­ple who show near trans­fer are more like­ly to show far trans­fer. For a per­son skilled at play­ing a game, such as Wor­dle, near trans­fer refers to being skilled at sim­i­lar games, such as a cross­word puz­zle. An exam­ple of far trans­fer for this per­son would be the abil­i­ty to bet­ter focus on dai­ly life activ­i­ties.

New book provides practical guidance for women (and men) to rebalance our lifestyles and build Cognitive Reserve

by

On one of our “walk and talks” around the lush trails of Rock Creek Park in DC sur­round­ed by bik­ers, run­ners, cars and the occa­sion­al deer, Wendy and Lisa talked about aging. Wendy’s moth­er, who had her chil­dren in her ear­ly 20s, was still join­ing the family’s gru­el­ing sum­mer hikes with her chil­dren and nine grand­chil­dren well into her 60s. Wendy mused about how much old­er she would be when their kids could have their own kids. It dawned on her that her health was not just a here and now issue, but an invest­ment in that future. We agreed to help each oth­er cul­ti­vate the habits and make time to build strength as well as reserves, both phys­i­cal and men­tal, for the long-term. Their goal: to enjoy being active in their 40s and 50s while also lay­ing the ground­work to con­tin­ue being active into their 60s, 70s, and beyond.

The Do’s and Don’ts of Harnessing Technology (and Anxiety) for Good

by

Wel­come to a new edi­tion of Sharp­Brains’ e‑newsletter, fea­tur­ing impor­tant brain & men­tal health news plus a few fun brain teasers to test your rea­son­ing skills and more…

#1. Chal­lenge ahead: Har­ness­ing tech­nol­o­gy for good men­tal health

“Tech­nol­o­gy can not only help us grow out of unhealthy habits, it is also pos­si­ble to expand human men­tal capac­i­ties … although it will be nec­es­sary to ana­lyze “the how and when” of these uses: they must be eth­i­cal­ly sound and ensure that results are ben­e­fi­cial to soci­ety.” — our very own Álvaro Fer­nán­dez, hop­ing you all agree 🙂

If you pre­fer to read the arti­cle in Span­ish: Cómo hac­er de la tec­nología un ali­a­do en el cuida­do de la salud mental

#2. On neu­ro­plas­tic­i­ty, young brains, and smartphones

“As with any tool, behav­ior, activ­i­ty, or tech­nol­o­gy, smart phones have the poten­tial to be either a use­ful and high­ly con­struc­tive asset or a destruc­tive and harm­ful diver­sion from life … What is the impact on brain devel­op­ment dur­ing the first 25 years of life when a sig­nif­i­cant part of each day is spent look­ing into a smart phone and the result­ing cog­ni­tive and emo­tion­al experiences?”

#3. Explor­ing links between hear­ing loss, demen­tia and the ‘cog­ni­tive reserve’ — plus the role of hear­ing aids

“Cer­tain types of demen­tia, par­tic­u­lar­ly vas­cu­lar demen­tia, are caused when there is less blood flow reach­ing the brain. This can dam­age our brain cells. Recent stud­ies have also shown that the parts of our brain that process sounds (our audi­to­ry sys­tem) have many blood ves­sels and are vul­ner­a­ble to dam­age … Anoth­er area of research is look­ing at whether hear­ing loss indi­rect­ly affects demen­tia risk by mak­ing it hard­er for peo­ple to stay con­nect­ed. Social iso­la­tion is anoth­er known risk fac­tor for dementia.”

#4. Com­put­er-assist­ed cog­ni­tive behav­ior ther­a­py (CCBT) may out­per­form Treat­ment as Usu­al (TAU) in help­ing patients reduce depres­sion, improve 6‑month remis­sion rates

“The find­ings of this ran­dom­ized clin­i­cal tri­al sug­gest that CCBT with a mod­est amount of clin­i­cian sup­port has poten­tial for wider-spread imple­men­ta­tion as an effec­tive, accept­able, and effi­cient treat­ment for depres­sion in pri­ma­ry care.”

#6. Wear­able EEG mon­i­tor­ing start-up Epi­tel rais­es $12.5M to mar­ket seizure detec­tion system

“It is time that EEGs for the brain become as acces­si­ble as EKGs for the heart to patients through­out the coun­try. For too long essen­tial neu­ro­log­i­cal ser­vices have been inac­ces­si­ble to large parts of our pop­u­la­tion” — Dr. Chaud­ery, Prin­ci­pal at Genoa Ven­tures (co-lead investor)

#7. Otsu­ka and Vir­tu­al Real­i­ty start-up Jol­ly Good sign $43M deal to pro­mote Social Skills Train­ing (SST) ther­a­pies, help­ing schiz­o­phre­nia patients first

“The com­bi­na­tion of SST and a phar­ma­ceu­ti­cal reg­i­men has been proven in stud­ies to reduce the recur­rence of men­tal dis­or­ders, the com­pa­nies said. Their first joint­ly devel­oped pro­gram will be direct­ed toward schiz­o­phre­nia patients, and they’re pre­dict­ing that the immer­sive nature of Jol­ly Good’s VR will make the SST ther­a­py more engag­ing and effec­tive than stan­dard methods.”

#8. Q&A with Dr. Wendy Suzu­ki on the parasym­pa­thet­ic ner­vous sys­tem and har­ness­ing anx­i­ety for good

“Most peo­ple have all heard of the fight-or-flight system—that’s the stress sys­tem, it makes your heart rate go up and you can run away real­ly fast. Well, peo­ple don’t real­ize that through evo­lu­tion in par­al­lel with the fight-or-flight sys­tem evolved an equal and oppo­site part of our ner­vous sys­tem that’s nick­named the “rest-and-digest” part of the ner­vous sys­tem, or parasym­pa­thet­ic ner­vous sys­tem. It’s basi­cal­ly the de-stress­ing part of our ner­vous sys­tem. That is what we need to acti­vate to bring our­selves back to equi­lib­ri­um when we’re in a stress­ful state.”

 

Final­ly, as promised, a few fun brain teasers to test your rea­son­ing skills–and more. Enjoy!

#9. Test your mem­o­ry and rea­son­ing skills with these proverbs

#10. Brain teas­er: Will you fin­ish your the­sis on time?

#11. Did you notice the jump? Good rea­son­ing and prob­lem-solv­ing often requires prop­er atten­tion to detail…

 

Wish­ing you and yours a healthy and safe March,

On neuroplasticity, young brains, and smartphones

by

Neu­ro­plas­tic­i­ty and Smart Phones (Psy­chi­atric Times):

In med­ical school, I was taught that the brain is hard­wired at birth. Dur­ing the past 30 years, neu­ro­science has defin­i­tive­ly shown that this is not the case at all. As our under­stand­ing of brain devel­op­ment advanced, it became clear that, dur­ing the first 3 years of life, neu­rons in the brain pro­lif­i­cal­ly form synap­tic con­nec­tions to be pre­pared for many diverse func­tion­al tasks, most of which it will nev­er encounter. From aged 3 years onward, the cir­cuits fre­quent­ly used strength­en their con­nec­tions while those serv­ing no func­tion are pruned away. Hence the com­mon phrase, “Neu­rons that fire togeth­er, wire togeth­er.” [Read more…] about On neu­ro­plas­tic­i­ty, young brains, and smartphones
