Our study, along
with prior studies, supports the notion that «cognitive reserve» resulting from early - life and lifelong education and cognitive stimulation may be a potent strategy for the primary prevention of dementia in both high - and
low - income countries around the world.21 However, it should be noted that the relationships among education, brain biology, and cognitive function are complex and likely multidirectional; for instance, a number of recent population - based studies have shown genetic links
with level of educational attainment, 22,23 and
with the risk for cognitive decline in later life.24 Higher levels of educational attainment are also associated
with health behaviors (eg,
physical activity, diet, and smoking), more cognitively - complex occupations, and better access to health care, all of which may play a role in decreasing lifetime dementia risk.

The researchers also factored in other characteristics of the participants that have previously been correlated
with dementia risk including
physical activity, age, sex, level of education, obesity,
low body mass index (BMI), and a history of high blood pressure, stroke, or diabetes.
A potential explanation for the secular trend may be that while improved treatment for cardiovascular risk factors or complicating diseases has reduced mortality in all weight classes, the effects may have been greater at higher BMI levels than at
lower BMI levels.12 Because obesity is a causal risk factor for hypertension, diabetes, cardiovascular disease, and dyslipidemia,15,19 - 22 obese individuals may have had a higher selective decrease in mortality.18 Indirect evidence of this effect is seen in the findings as the deaths occur at similar time periods in the 3 cohorts, but cohorts recruited at later periods have an increase in the BMI associated
with the
lowest mortality, possibly suggesting a period effect related to changes in clinical practice, such as improved treatments, or general public health status, such as decreased smoking or increased
physical activity.
