While the aging Boomers face myriad health concerns, one of the biggest is cognitive decline and Alzheimer’s disease, which currently affects up to 5 million Americans. Deborah Kotz, writing for US News & World Reports, noted there is great interest among consumers in making preventive lifestyle choices to fight the loss of mental function. However, research is still unclear because of limitations in determining causality versus association in looking at, for example, level of education or dietary factors.
This is not to say there aren’t steps to be taken. In the area of nutrition, Kotz noted the science is strong in the area of omega-3 essential fatty acids (EFAs) from fish or fish oil supplements, showing an association between higher levels of omega-3 intake and a lower risk of cognitive decline. Evidence is limited for other nutrients such as antioxidants or B vitamins or dietary changes. Preliminary evidence also sees a link between exercise or active hobbies and preservation of cognitive function. And the link between smoking and loss of brain function is fairly conclusive.
There has also been a consistent association between depression and Alzheimer’s, although in a chicken-and-egg scenario. One step to take is increasing social connections and cognitive engagement, practicing mentally challenging tasks and keeping close social ties.
