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

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…

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

In fact, her new book is called Good Anx­i­ety: Har­ness­ing the Pow­er of the Most Mis­un­der­stood Emo­tion. If you’re skep­ti­cal, so…

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

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.…
