ADHD
Though research is still being conducted, scientists believe that up to thirty percent of children born with ADHD are linked to either tobacco smoke exposure prior to birth or lead exposure after birth. For children whose mothers smoked during pregnancy, they were over two times as likely to develop ADHD. However, it is not just smoke, other toxins may also lead to ADHD. For example, take alcohol. Studies have reported brain changes related in both ADHD and prenatal alcohol exposure that show striking similarity, suggesting that prenatal exposure to teratogenic substances may, have a role in deviant brain development in ADHD.

Mercury,in a new study, was reported by researchers that children who are exposed to higher levels of mercury in the womb are more likely to exhibit attention problems, hyperactivity, and other ADHD symptoms.
