Early life socioeconomic circumstance and late life brain hyperintensities--a population based cohort study.

<h4>Context</h4>There have been many reports confirming the association between lower childhood socioeconomic circumstance and cardiovascular disease but evidence for links with cerebrovascular disease is contradictory. Hyperintensities on brain magnetic resonance imaging are associated...
