Lead exposure linked to ADHD in kids with genetic mutation

Association for Psychological Science

Exposure to small amounts of lead may contribute to ADHD symptoms in children who have a particular gene mutation, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

"This research is valuable to the scientific community as it bridges genetic and environmental factors and helps to illustrate one possible route to ADHD. Further, it demonstrates the potential to ultimately prevent conditions like ADHD by understanding how genes and environmental exposures combine," says lead researcher Joel Nigg, professor of psychiatry and behavioral neuroscience at the OHSU School of Medicine.
