Jobs with low physical stress and good working conditions linked to larger hippocampus and better memory

by

CSU study links phys­i­cal stress on the job with brain and mem­o­ry decline in old­er age (press release):

A new study out of Col­orado State Uni­ver­si­ty has found that phys­i­cal stress in one’s job may be asso­ci­at­ed with faster brain aging and poor­er memory.

Aga Burzyn­s­ka, an assis­tant pro­fes­sor in the Depart­ment of Human Devel­op­ment and Fam­i­ly Stud­ies, and her research team con­nect­ed occu­pa­tion­al sur­vey respons­es with brain-imag­ing data from 99 cog­ni­tive­ly nor­mal old­er adults, age 60 to 79. They found that those who report­ed high lev­els of phys­i­cal stress in their most recent job had small­er vol­umes in the hip­pocam­pus and per­formed poor­er on mem­o­ry tasks. The hip­pocam­pus is the part of the brain that is crit­i­cal for mem­o­ry and is affect­ed in both nor­mal aging and in dementia.

On World Health Day 2020, let’s discuss the stress response and the General Adaptation Syndrome (2/3)

The hypothalamus–pituitary–adrenal (HPA) axis acts to release cor­ti­sol into the blood stream, as cor­ti­sol calls the body into action to com­bat stress. When high amounts of cor­ti­sol inter­act with the hypo­thal­a­mus, the HPA axis will slow down its activ­i­ty. The amyg­dala detects stress, while the pre­frontal cor­tex reg­u­lates our reac­tions to stress. Source: Bezdek K and Telz­er E (2017) Have No Fear, the Brain is Here!

Stress was put on the map, so to speak, by a Hun­gar­i­an — born Cana­di­an endocri­nol­o­gist named Hans Hugo Bruno Selye (ZEL — yeh) in 1950, when he pre­sent­ed his research on rats at the annu­al con­ven­tion of the Amer­i­can Psy­cho­log­i­cal Asso­ci­a­tion. To explain the impact of stress, Selye pro­posed some­thing he called the Gen­er­al Adap­ta­tion Syn­drome (GAS), which he said had three com­po­nents. Accord­ing to Selye, when an organ­ism expe­ri­ences some nov­el or threat­en­ing stim­u­lus it responds with [Read more…] about On World Health Day 2020, let’s dis­cuss the stress response and the Gen­er­al Adap­ta­tion Syn­drome (2/3)

Neuroscience tips about gratitude, aging, pain and the brain: An interview with Dr. Daniel Levitin

About 13 years ago, I watched my very vital moth­er die a slow death from Lewy-Body demen­tia. For me, it was a wake­up call. If there were any­thing I could do to stay healthy myself—to avoid the slow decline of an aging brain—I want­ed to do it. But what real­ly helps us stay sharp longer? And how can we sep­a­rate fad ideas from sol­id, evi­dence-based advice around aging?

Ready for a Hap­py New Year  and Hap­py New Decade?

Here’s a spe­cial edi­tion of the Sharp­Brains month­ly e‑newsletter fea­tur­ing the lat­est on brain health and men­tal well-being — we hope you enjoy these tips and advice about what to do, and what not to, to pro­mote brain well­ness in 2020 and beyond:

Prac­tice Breath­ing & Com­pas­sion: Three evi­dence-based ways to devel­op a resilient mind

… and a Sport you love: Play sports (smart­ly) for a qui­eter brain

Chal­lenge your friends, often: For bet­ter mem­o­ry and think­ing skills at age 70, play cards and board games from age 11

… for exam­ple by solv­ing big prob­lems togeth­er: Mind­strong Health recruits slew of Sil­i­con Val­ley talent

When in trou­ble, con­sid­er ther­a­py before meds: To treat depres­sion, ther­a­py alone works bet­ter than ther­a­py com­bined with antidepressants

… your might even be able to access it pri­vate­ly, online: First Dig­i­tal Health For­mu­la­ry by Express Scripts includes CBT-based pro­grams to treat depres­sion, anx­i­ety and insomnia

Final­ly, beware “brain-boost­ing” sup­ple­ments, and don’t jump on direct-to-con­sumer tran­scra­nial direct cur­rent stim­u­la­tion (tDCS) unless you under­stand Pros and Cons

… but always keep your mind open to awe and to new ways to tease your brain, see the world around us and even shape it!

 

Wishing you a happy, healthy and prosperous New Year and New Decade,

This start­up just raised $8 mil­lion to help busy doc­tors assess the cog­ni­tive health of 50 mil­lion seniors (TechCrunch):

“…star­tups increas­ing­ly rec­og­nize oppor­tu­ni­ties to cater to this aging pop­u­la­tion. Some are devel­op­ing prod­ucts to sell to indi­vid­u­als and their fam­i­ly mem­bers direct­ly; oth­ers are com­ing up with ways to empow­er those who work direct­ly with old­er Americans.

BrainCheck, a 20-per­son, Hous­ton-based start­up whose cog­ni­tive health­care prod­uct aims to help physi­cians assess and track the men­tal health of their patients, is among the lat­ter. Investors like what it has put togeth­er, too. Today, the start­up is announc­ing $8 mil­lion in Series A fund­ing co-led by S3 Ven­tures and Ten­sil­i­ty Ven­ture Part­ners.
