Can exposure to toxins or other substances during pregnancy cause ADHD?

ANSWER

Studies show that pregnant women who smoke or drink alcohol may have a higher risk of having a child with ADHD. Exposure to lead, PCBs, or pesticides may also have a role.

Researchers believe that some toxins may interfere with brain development, which could lead to hyperactivity, rash behavior, and inattentiveness.
