Research Shows More Than 150 Million Mental Diagnoses May Be Linked to Lead in Gasoline

A history of lead in gasoline may be behind tens of millions of mental health conditions in the United States, according to new research.

“We’ve shifted the curve in the population for mental health problems, so that everyone has a greater liability in the mental illness symptoms, and that some people who were already at risk are going to develop diagnosable disorders sooner, more often or more kinds,” said coauthor of the study Dr. Aaron Reuben, assistant professor of clinical neuropsychology at the University of Virginia.

The study published Wednesday in The Journal of Child Psychology and Psychiatry estimates that about 151 million mental disorder diagnoses in the US are attributable to lead. The exposure likely would not have happened had lead not been in gasoline, Reuben added.
