Childhood Exposure to Lead Can Blunt IQ for Decades
A study reported in the March 28, 2017 issue of the Journal of the American Medical Association (JAMA), suggests that exposure to lead as a child can affect an adult decades later and that there is a link between early childhood lead exposure and a dip in a person’s later cognitive ability and socioeconomic status.
Aaron Reuben, the study’s co-author and a graduate student in clinical psychology at Duke University reports that “Lead damages brain health. We know what it does. What we didn’t know until this study was, how long do those effects last?…There’s no reason to believe they ever go away.”
