Question

Maternal smoking during pregnancy has been linked to a higher risk of ADHD symptoms in children. This association can be viewed within the epigenetic framework, which suggests that prenatal exposure to nicotine can cause changes in DNA methylation patterns that can alter gene expression and contribute to the development of ADHD symptoms. While not all children prenatally exposed to nicotine will develop ADHD symptoms, the majority are at higher risk. The DD genotype, which has been associated with a higher risk of ADHD, is not specifically linked to prenatal nicotine exposure.
