Large neuroimaging study finds social isolation to be an early indicator of increased dementia risk

June 23, 2022 by The Conversation Leave a Comment

Why do we get a buzz from being in large groups at fes­ti­vals, jubilees and oth­er pub­lic events? Accord­ing to the social brain hypoth­e­sis, it’s because the human brain specif­i­cal­ly evolved to sup­port social inter­ac­tions. Stud­ies have shown that belong­ing to a group can lead to improved well­be­ing and increased sat­is­fac­tion with life.

Unfor­tu­nate­ly though, many peo­ple are lone­ly or social­ly iso­lat­ed. [Read more…] about Large neu­roimag­ing study finds social iso­la­tion to be an ear­ly indi­ca­tor of increased demen­tia risk

Study finds that playing videogames may be more cognitively beneficial for children than other forms of screentime (social media, watching videos/ TV)

June 1, 2022 by The Conversation Leave a Comment

Many par­ents feel guilty when their chil­dren play video games for hours on end. Some even wor­ry it could make their chil­dren less clever. And, indeed, that’s a top­ic sci­en­tists have clashed over for years.

In our new study, we inves­ti­gat­ed how video games affect the minds of chil­dren, inter­view­ing and test­ing more than 5,000 chil­dren aged ten to 12. And the results, pub­lished in Sci­en­tif­ic Reports, will be sur­pris­ing to some.

On mental fitness beliefs, lifestyles and new tools like apps, digital therapeutics, virtual reality, “brain age gaps” and more

May 31, 2022 by SharpBrains Leave a Comment

Wel­come to a new edi­tion of Sharp­Brains’ e‑newsletter, fea­tur­ing time­ly brain & men­tal health news and a fun cou­ple of math brain teasers.

#1. Study on the “ABCs of Men­tal Health” finds that sim­ply believ­ing you can improve men­tal well­be­ing helps actu­al­ly improve it

Beliefs mat­ter.

#2. “Dig­i­tal ther­a­peu­tics” vs. “Men­tal health apps”: A grow­ing debate on stan­dards, reg­u­la­tion and efficacy

Def­i­n­i­tions matter.

#3. How ’sleep­ing on it’ can help the pre­frontal cor­tex reg­u­late emo­tion­al respons­es, mak­ing us feel bet­ter in the morning

Sleep mat­ters.

#4. NICE in the UK issues rec­om­men­da­tion for Sleepio app, the dig­i­tal cog­ni­tive behav­iour­al ther­a­py for insom­nia by Big Health

Inno­va­tion mat­ters: “At a price of £45 per per­son, Sleepio is cost sav­ing com­pared with usu­al treat­ment in pri­ma­ry care. This is based on an analy­sis of pri­ma­ry care resource use data before and after Sleepio was intro­duced in 9 GP prac­tices. Health­care costs were low­er at 1 year, most­ly because of few­er GP appoint­ments and sleep­ing pills prescribed.”

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

Lifestyle mat­ters: “The more com­plex our lives are, the more we need sim­ple things that can ground us and help us to be more resilient – to rebal­ance and rebal­ance and rebal­ance again. Build­ing the men­tal mus­cles to find bal­ance when one gets off bal­ance is a crit­i­cal skill thrive and to build cog­ni­tive reserve in our fast-chang­ing times. As our month­ly gath­er­ings showed us over the years, prac­tic­ing rebal­ance in good com­pa­ny not only rein­forces neur­al path­ways and capa­bil­i­ties but also strength­ens the bonds of trust and con­fi­dence that are invalu­able to build a healthy envi­ron­ment to thrive in.”

#6. Study: Auto­mat­ed VR psy­chother­a­py can help reduce anx­i­ety and dis­tress, espe­cial­ly among those with psy­chosis and severe agoraphobia

One of the ben­e­fits of VR is that patients know they are in a sim­u­la­tion, which enables “psy­cho­log­i­cal dis­tance from prob­lem­at­ic reac­tions,” the study authors wrote. “The process of find­ing the best uses and imple­men­ta­tion meth­ods of this immer­sive tech­nol­o­gy at scale in men­tal health is only beginning.”

#7. Fund­ing for dig­i­tal health start-ups, espe­cial­ly in men­tal health, fall sub­stan­tial­ly in Q1’22

“While all tech sec­tors received small­er fund­ing totals than the pre­vi­ous quar­ter, dig­i­tal health plunged much fur­ther than oth­ers did … investor inter­est in men­tal health tech wavered as the mar­ket and pub­lic com­pa­nies like Talk­space and Cere­bral come under scrutiny.”

#8. Deep learn­ing mod­el built on neu­roimag­ing data iden­ti­fies “Brain Age Gaps” as mark­ers of Alzheimer’s dis­ease (AD)

“The main find­ing of our study is that we could indeed find evi­dence that high brain age gap is behav­ing as an accel­er­at­ed brain aging bio­mark­er.” — Dr. David Jones, neu­rol­o­gist at Mayo Clinic

Final­ly, a cou­ple fun brain teasers to help you flex your math/ cog­ni­tive men­tal muscles:

#9. Will you fin­ish your the­sis on time?

#10. Math brain teas­er requir­ing no math — just per­cep­tion and cognition

 

Wish­ing you and yours a healthy and stim­u­lat­ing June!

Study: Automated VR psychotherapy can help reduce anxiety and distress, especially among those with psychosis and severe agoraphobia

May 5, 2022 by SharpBrains Leave a Comment

Oxford Uni­ver­si­ty VR spin­out demon­strates sig­nif­i­cant psy­chother­a­py ben­e­fits in Lancet study (Fierce Healthcare):

Vir­tu­al real­i­ty can help treat symp­toms in patients with psy­chosis, accord­ing to a new study pub­lished in The Lancet Psychiatry.

GameChangeVR auto­mates psy­chother­a­py, guid­ing users with a vir­tu­al coach. It was devel­oped by Oxford­VR, a dig­i­tal ther­a­peu­tics com­pa­ny, the Uni­ver­si­ty of Oxford and Oxford Health NHS Foun­da­tion Trust … The study, based on 346 patients, found that auto­mat­ed VR ther­a­py led to “sig­nif­i­cant reduc­tions” in symp­toms of anx­ious avoid­ance and dis­tress. The tech­nol­o­gy espe­cial­ly ben­e­fit­ed those with severe symp­toms. The study con­clud­ed that the tech­nol­o­gy has the poten­tial to increase access to effec­tive care for psy­chosis.

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

February 28, 2022 by SharpBrains

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…

On neuroplasticity, young brains, and smartphones

February 14, 2022 by SharpBrains

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
