Annotation: This study investigated the etiological overlap between symptoms of major depressive disorder (MDD) and attention-deficit/hyperactivity disorder (ADHD) in children and adolescents.
Abstract: Evidence was found to support a common genetic influence underlying symptoms of hyperactivity/inattention and negative mood in a twin sample. The finding supports the conjecture of a shared genetic etiology between attention-deficit/hyperactivity disorder (ADHD) and major depressive disorder (MDD) in both children and adolescent males and females. Evidence suggests that there is substantial comorbidity between ADHD and MDD in childhood and adolescence. This study investigates the degree to which etiological factors are shared between the symptoms of these significantly heritable disorders. The study measured both ADHD and MDD in a sample of 670 twin pairs and used bivariate structural equation modeling in order to partition any covariation between the two into shared genetic and environmental pathways.
