Rachel Klein, PhD, the Fascitelli Family Professor of Child and Adolescent Psychiatry and the Director of the Anita Saltz Institute for Anxiety and Mood Disorders at the NYU Child Study Center and Department of Child and Adolescent Psychiatry, NYU Langone Medical Center, discusses a unique study that followed children with ADHD into adulthood. Although most children went on to lead successful adult lives, antisocial personality disorder — a set of behaviors that must first present in adolescence — was seen to develop in around 20% of adult patients.

Dr. Klein discusses conduct disorder as a precursor to antisocial personality disorder; the agressive, manipulative, and impulsive behavior that identifies the disorder in adulthood; and what parents can do to recognize the signs of these behaviors and get their children help before the disorder is solidified in adulthood.
