Ballroom dancing can reduce aging-related brain atrophy in the hippocampus (and, more than treadmill walking!)

by

Social ball­room danc­ing can improve cog­ni­tive func­tions and reduce brain atro­phy in old­er adults who are at increased risk for Alzheimer’s dis­ease and oth­er forms of demen­tia. That’s the key find­ing of my team’s recent­ly pub­lished study in the Jour­nal of Aging and Phys­i­cal Activity.

In our study, we enrolled 25 adults over 65 years of age in either six months of twice-week­ly ball­room danc­ing class­es or six months of twice-week­ly tread­mill walk­ing class­es. None of them were engaged in for­mal danc­ing or oth­er exer­cise pro­grams.

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

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.

Study: Building muscle mass helps delay cognitive decline beyond the value of exercise itself

A new rea­son to build mus­cle: brain health (The Globe and Mail):

… a recent study from researchers at McGill Uni­ver­si­ty, pub­lished in the jour­nal JAMA Net­work Open, offers a new rea­son for con­tin­u­ing to work on build­ing mus­cle: It’s good for your brain, not just your biceps. Greater mus­cle mass, the results sug­gest, helps ward off cog­ni­tive decline in old­er adults beyond what you’d expect based on their exer­cise lev­els alone.

Anticholinergic drugs found to significantly increase risk of cognitive decline, especially among those with Alzheimer’s Disease biomarkers or genetic predisposition

Com­mon Class of Drugs Linked to Increased Risk of Alzheimer’s Dis­ease (UC San Diego release):

A team of sci­en­tists, led by researchers at Uni­ver­si­ty of Cal­i­for­nia San Diego School of Med­i­cine, report that a class of drugs used for a broad array of con­di­tions, from aller­gies and colds to hyper­ten­sion and uri­nary incon­ti­nence, may be asso­ci­at­ed with an increased risk of cog­ni­tive decline, par­tic­u­lar­ly in old­er adults at greater risk for Alzheimer’s dis­ease (AD) … cog­ni­tive­ly nor­mal study par­tic­i­pants who were tak­ing at least one anti­cholin­er­gic drug at base­line were 47 per­cent more like­ly to devel­op mild cog­ni­tive impair­ment (MCI), often a pre­cur­sor to demen­tia such as AD, while being tracked over a peri­od of up to a decade com­pared to par­tic­i­pants who did not take such drugs.

Large study finds that placebo works as well as vitamin D supplements to prevent depression and improve mood

Large Study Con­firms Vit­a­min D Does Not Reduce Risk of Depres­sion in Adults (Mass Gen­er­al press release):

Vit­a­min D sup­ple­men­ta­tion does not pro­tect against depres­sion in mid­dle-age or old­er adult­hood accord­ing results from one of the largest ever stud­ies of its kind … “There was no sig­nif­i­cant ben­e­fit from the sup­ple­ment for this pur­pose. It did not pre­vent depres­sion or improve mood,” says Olivia I. Okereke, MD, MS, of the Mass­a­chu­setts Gen­er­al Hos­pi­tal (MGH) Psy­chi­a­try Department.

Hear­ing Aids Linked to Low­er Risk of Demen­tia, Depres­sion and Falls, Study Finds (Michi­gan Health Lab):

“Old­er adults who get a hear­ing aid for a new­ly diag­nosed hear­ing loss have a low­er risk of being diag­nosed with demen­tia, depres­sion or anx­i­ety in the fol­low­ing three years, and a low­er risk of suf­fer­ing fall-relat­ed injuries, than those who leave their hear­ing loss uncor­rect­ed, a new study finds.
