Smoking, Diabetes, Obesity May Shrink Your Brain

As if there weren't already enough good reasons to avoid smoking and keep your weight, blood sugar levels and blood pressure all under control, a new study suggests these risk factors in middle age may cause your brain to shrink, leading to mental declines up to a decade later.

Evaluating data from 1,352 participants whose average age was 54 in the Framingham Offspring Study -- which began in 1971 -- researchers from the University of California, Davis found that smoking, high blood pressure, diabetes and being overweight were each linked to potentially dangerous vascular changes in the brain.
