Are Certain Professionals, including Lawyers, Less at Risk for Cognitive Decline?

The Washington Post published an interesting article reporting on the recent Alzheimer’s Association International Conference in Toronto.  According to the article, 

Two studies looked at how complex work and social engagement counteract the effects of unhealthy diet and cerebrovascular disease on cognition. One found that while a “Western” diet (characterized by red and processed meats, white bread, potatoes, pre-packaged foods, and sweets) is associated with cognitive decline, people who ate such food could offset the negative effects and experienced less cognitive decline if they also had a mentally stimulating lifestyle.

 

Occupations that afforded the highest levels of protections included lawyer, teacher, social worker, engineer and doctor; the fewest protections were seen among people who held jobs such as laborer, cashier, grocery shelf stocker, and machine operator.

 

“You can never totally forget about the importance of a good diet, but in terms of your risk of dementia, you are better able to accommodate some of the brain damage that is associated with consuming this kind of (unhealthy) diet,” said Matthew Parrott, a post-doctoral fellow at the Rotman Research Institute in Toronto, who presented the study.

 

In another study, researchers found that people with increased white matter hyperintensities (WMHs) – white spots that appear on brain scans and are commonly associated with Alzheimer’s and cognitive decline – were able to better tolerate WMH-related damage if they worked primarily with other people rather than with things or data.
