RT Journal Article SR Electronic A1 Helwick, Caroline T1 Conduct Disorder and ADHD: Predictors for Substance Abuse JF MD Conference Express YR 2010 FD SAGE Publications VO 10 IS 4 SP 12 OP 13 DO 10.1177/155989771004007 UL http://mdc.sagepub.com/content/10/4/12.2.abstract AB Attention deficit hyperactivity disorder (ADHD) and associated comorbidities are known to be risk factors for substance abuse in adolescence and young adulthood, but few studies have examined the early childhood risk factors that may predispose to this behavior. In a 10-year follow-up of children with ADHD, the occurrence of substance use disorder was increased compared with controls, especially among ADHD youth with early conduct disorder.
