Alzheimer's and the Complex Jobs That Keep Your Brain Fit

Organizers, doing complex work with data involving complex interaction with other people, such as teaching, managing people,and conducting negotiations has been found to ward off dimentia and keep the brain fit.
That’s the conclusion of a University of a South Florida study published in the Journal of Gerontology: Psychological Science. According to lead author Ross Andel, PhD, the findings "suggest that greater complexity of work, and particularly complex work with people, may reduce the risk of Alzheimer’s disease."
The researchers studied 10,079 Swedish men and women, all of them twins, who were at least age 65 by 1998; 225 had been diagnosed with dimentia. Besides looking for overall connections between complex work and later risk of dementia, the scientists were able to compare pairs of twins—one with dementia, one without.
The strongest link to lower Alzheimer’s incidence—22% reduced risk—was found among subjects who’d held jobs involving complex interactions with other people, such as teaching, managing people, conducting negotiations or dealing with customers. The association was found regardless of level of education. This group also had a slightly lower risk of all forms of dementia.
In the twins comparisons, some evidence also pointed to a protective effect from complex work with data, such as compiling, organizing or analyzing information.
