Association between Depression and Attention Deficit Hyperactivity Disorder among Patients with Substance Use Disorder

Abstract

ttention-deficit hyperactivity disorder (ADHD) is the current diagnosis for what was previously labeled minimal brain damage (Barkley 1998). ADHD is a complicated neurodevelopmental disorder; the etiology involves genetic predisposition, neurochemical, neuroanatomical anomalies and environmental factors (Schweren et al., 2013). Clinicians thought (ADHD) disappeared along with childhood. But contrary to popular belief, at least 60% of children with ADHD continue to exhibit features of the disorder during adulthood (Wilens et al., 2004).
