(PHILLY) — Kids at the head of the class not only have better college and job prospects, they may also stave off Alzheimer's disease, two new studies suggest.
People with the best school grades and most complex jobs later on -- as managers, teachers or executives, for example -- have roughly a 40 to 60 percent reduced risk of developing dementia, according to two teams of Swedish researchers.
But, both Swedish studies only found an association between school grades, later jobs and risks of dementia, and not a proven cause-and-effect link.

"We are just starting to figure out that there is this lifetime risk for developing Alzheimer's disease," said Dean Hartley, director of science initiatives at the Alzheimer's Association, which played no part in either study.
