Exposure to Lead May Contribute to ADHD

Forbes.com reports that

"new research suggests that certain children are more likely to develop
attention-deficit hyperactivity disorder (ADHD) when exposed to lead in their
environment."

The study found that the lead exposure caused more problems with boys than with girls, which could also be one of the reasons that more often boys suffer from ADHD than girls. While the exact cause of ADHD isn't know, this is a significant step toward finding the cause.
