With juvenile crime on the rise, understanding and preventing juvenile delinquency is one of the greatest challenges facing mental health professionals today. Recognizing early signs of conduct disorder (CD) can be difficult, but identifying risk factors is an important step in preventing a child's progression to CD or Antisocial Personality Disorder (APD). This paper focuses on various risk factors for CD and APD, such as intrinsic individual differences, psychosocial/environmental factors, genetic and neurochemical factors. Early recognition and intervention may prevent the progression from aggressive and maladaptive behaviors to CD and later APD.
