The brain, of course.
In other words, if you want to lower your risk of cognitive decline and dementia as you age, the best way to do that is to work on lowering your risk of cardiovascular disease.
So in a recent study, researchers using PET scans to detect brain changes were able to identify signs of future dementia and to link such changes to “standard cardiovascular (CV) disease risk factors”.
In other words, the more risk factors for CV disease a person had in this study, the more PET scan changes they had to indicate a higher risk of later dementia.
And just in case you think they were looking at advanced seniors who already had proven cognitive decline, you should know that the study population was 40 to 54 years old with no outward signs yet of cognitive decline.
