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

by

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

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

by

Anx­i­ety can feel like a heavy weight that we didn’t ask to car­ry. Who wouldn’t love to get rid of it?

But neu­ro­sci­en­tist Wendy Suzu­ki wants to chal­lenge the way we look at our anx­i­ety. In fact, her new book is called Good Anx­i­ety: Har­ness­ing the Pow­er of the Most Mis­un­der­stood Emo­tion.

If you’re skep­ti­cal, so was I. But Suzuki’s point is that anx­i­ety is a nat­ur­al human emo­tion, one that evolved to serve a pur­pose. We feel anx­ious when there is some kind of dan­ger; it primes our body to fight or flee from that dan­ger, in hopes that we’ll end up bet­ter off (i.e., alive). In the same way, our mod­ern anx­i­eties can be a warn­ing sig­nal for things that are wrong: not enough rest, too much mul­ti­task­ing, iso­la­tion from oth­ers. Our anx­ious ener­gy alerts us to change our lives for the bet­ter, she argues.

Promote brain plasticity and keep your mind at ease by taking your daily “exercise pill”

by

As with many oth­er physi­cians, rec­om­mend­ing phys­i­cal activ­i­ty to patients was just a doc­tor chore for me – until a few years ago. That was because I myself was not very active. Over the years, as I picked up box­ing and became more active, I got first­hand expe­ri­ence of pos­i­tive impacts on my mind. I also start­ed research­ing the effects of dance and move­ment ther­a­pies on trau­ma and anx­i­ety in refugee chil­dren, and I learned a lot more about the neu­ro­bi­ol­o­gy of exer­cise.

The neuroscience behind why our brains will need time to adjust to ‘un-social distancing’

by

With COVID-19 vac­cines work­ing and restric­tions lift­ing across the coun­try, it’s final­ly time for those now vac­ci­nat­ed who’ve been hun­kered down at home to ditch the sweat­pants and reemerge from their Net­flix caves. But your brain may not be so eager to dive back into your for­mer social life. [Read more…] about The neu­ro­science behind why our brains will need time to adjust to ‘un-social distancing’

Debate: Are depression and dementia two sides of the same coin? And, if they are, how to best approach treatment?

by

Every sev­en sec­onds, some­one in the world is diag­nosed with demen­tia. A typ­i­cal case that I often see in my prac­tice is as fol­lows: A 76-year-old woman has a two-year his­to­ry of pro­gres­sive wors­en­ing of short-term mem­o­ry and cog­ni­tive decline. She can’t recall the names of her grand­chil­dren and is dev­as­tat­ed by her dete­ri­o­rat­ing abilities.

How­ev­er, this is not the first time in her life that she has had feel­ings of loss and despair. Over the past 30 years, she has inter­mit­tent­ly strug­gled with depres­sion and anx­i­ety. Her fam­i­ly has many ques­tions: Does she have demen­tia or Alzheimer’s? Could her depres­sion have led to a demen­tia diag­no­sis? Is it only depres­sion and not demen­tia? These are all good ques­tions and the col­lec­tive answer to them is “yes.” [Read more…] about Debate: Are depres­sion and demen­tia two sides of the same coin?
