Main results


In a population-based cohort that was followed-up for 31 years, the cumulative burden of BP, serum total- and LDL-C, and smoking from childhood and adolescence, were independently associated and combined with midlife cognitive performance. These findings support the implementation of primordial strategies to prevent CV risk factors from childhood, in order to promote cognitive health in adulthood.

Editorial comment

In their editorial article, Lloyd-Jones and Allen start with a clear positioning of an unmet medical need: ‘It is increasingly being recognized that loss of ideal cardiovascular health and exposure to elevated cardiovascular risk factor levels at young ages, and the accumulated burden of these risk factors, is a major contributor to health outcomes in later life. In fact, the top global research priorities for the next decade in dementia research call for a focus on prevention; however, until recently, it has been unclear at what ages this accumulated burden starts to accrue and when prevention efforts should begin.’

In this context, they summarize the study of Rovio et al, and focus on one important weakness. A single measure of cognitive performance was used in the study, leaving open the chicken-or-egg question: Are CV risk factors leading to limited cognitive function, or was the limited cognitive function already there during childhood, leading to unhealthy behaviors? A longitudinal analysis in the future might answer this question. For the time being, the authors of the editorial conclude: ‘Rovio et al show compelling data on how influential very early life exposures are on long-term health. They highlight how crucial it is to focus our efforts on primordial prevention in childhood so we can help current and future generations remain in both ideal cardiovascular and cognitive health.’
