Subject: Chapter 11 and ADHD

In chapter 11, the author discussed the proposed etiologies of ADHD. He states that ADHD can be caused by �low levels of certain neurotransmitters�, prenatal and postnatal abnormalities, and environmental toxins such as lead�. It has also been proposed that maternal prenatal smoking increases the chances of a child getting ADHD. However, I recently came across a research study that looked at both maternal prenatal smoking and low birth weight as possible risk factors for the development of ADHD, Oppositional Defiance Disorder (ODD) and Conduct Disorder (CD) (Nigg & Breslau, 2007). In regards to ADHD, the researchers found that although at first there seemed to be higher risks of developing ADHD with exposure to maternal prenatal smoking, the effects were no longer statistically significant once familial characteristics were controlled for (maternal substance use and educational level). What I found most interesting was that the study found that children who were exposed to maternal prenatal smoking had a higher risk of developing ODD, and through this, develop CD later in life.
