Brain-wide chemical changes linked to childhood lead exposure.

"Exposure to moderate levels of lead during childhood can permanently change important brain chemical levels later in life, suggests results from a large brain imaging study. The adults who had higher average blood lead levels as children also had lower levels of several key chemicals that are produced in different brain regions. These brain chemicals are critical to maintaining brain function. This is the first large brain imaging study in young adults followed since birth and adds new insights to the mechanism of lead exposure on brain function."
