Prenatal Nicotine Exposure As A Teratogen In Neurological Pathways, Monica Grover
Prenatal Nicotine Exposure As A Teratogen In Neurological Pathways, Monica Grover
AUCTUS: The Journal of Undergraduate Research and Creative Scholarship
Attention-deficit/hyperactivity disorder (ADHD) is the most heritable and commonly diagnosed childhood psychiatric disorder with 4% of all children being diagnosed with this disorder. Prenatal smoking has been found to be a risk factor for ADHD, a disorder that has been believed to be linked to the fluctuation of dopamine levels. Prenatal nicotine exposure in the second trimester influences dopaminergic neurological pathways by altering dopamine release levels. The altered dopamine levels make the fetus brain more sensitive to the nicotine, causing the nicotine exposure to be more dangerous in causing ADHD symptoms. Prenatal nicotine exposure alters the neurological pathway of the …

Stress And Anxiety In Adhd: Links To Sensory Over-Responsivity, Stacey E. Reynolds
Theses and Dissertations
Sensory Modulation Dysfunction (SMD) is characterized by an inability to consistently and accurately grade responses to sensory information. SMD, and specifically sensory over-responsivity (SOR), has been correlated with stress and anxiety in some developmentally delayed populations and has been associated with structures and functions of the hypothalamic-pituitary adrenal (HPA) axis. Recent attention has been given to HPA functioning in children with Attention Deficit Hyperactivity Disorder (ADHD), with a majority of studies identifying blunted or diminished cortisol patterns. In contrast, elevated cortisol has been associated with anxiety and anxious behaviors in both animal and human studies. The purpose of this study …
