  • Between 50% and 75% of adolescents with anxiety disorders and impulse control disorders (such as conduct disorder or attention deficit hyperactivity disorder) develop these during adolescence.
  • An estimated 67% to 70% of youth in the juvenile justice system have a diagnosable mental health disorder.
